Testing is a skill that is a vital part of every programmers training. Learning how to write good tests helps you write more robust code, and ensures that when you've written code that works, it keeps working long into the future. It can also help you write better code in the first place. It turns out that well architected code, with high cohesion and low coupling, is also easy to test - so writing code that is easy to test will almost always result in better overall code quality.
An important step in "levelling up" your testing experience is to start using a Continuous Integration, or CI service. A CI service is a tool that automatically runs your test suite every time someone makes a change - or every time someone proposes a change in the form of a pull request. Using a CI service makes sure that your code always passes your test suite - you can't accidentally slip in a change that breaks a test, because you'll get a big red warning notification.
CI is such an important service that many companies exist solely to provide CI-as-a-service. The BeeWare project has, for various projects, used TravisCI and CircleCI. Both these tools provide free tiers for open source projects, and have generously sponsored BeeWare with capacity upgrades at various times.
However, the BeeWare has had an interesting relationship with commercial CI services. This is for two reasons.
Firstly, our test suites - especially for VOC and Batavia - take a long time to run. These two projects require tests that repeatedly start and shut down virtual machines (for Java and JavaScript, respectively), and no matter how much you optimize the code being tested, the startup and shutdown time of a virtual machine eventually adds up. We also need to run our test suites on multiple versions of Python - at present, we support Python 3.4, 3.5 and 3.6, with 3.7 on the horizon. There are also subtle changes in micro versions that may require testing.
We've been able to speed up the duration of a test run by splitting up the test suite and running parts of the suite in parallel, but that forces us up against the second problem. Commercial CI services usually operate on a subscription model; higher subscriptions providing more simultaneous resources. However, our usage pattern is highly unusual. Most of the year, we get a slow trickle of pull requests that require testing. However, a couple of times a year, we have a large sprint, and we have a flood of contributions over a short period of time. At PyCon US, we have had groups of 40 people submitting patches - and they all need their submissions tested by CI. And time is a factor - the sprints only last a couple of days, so a fast turnaround on testing is essential.
If we were to subscribe to the top tier subscription levels of CircleCi and TravisCI, we still wouldn't have enough resources to support a sprint - but we'd be massively overresourced for the rest of the year. We'd also have to pay $750 or more a month for this service, which is a budget we can't afford.
So - we had a problem. To run our test suite effectively, we needed massively parallelized resources to run a test suite quickly; and at certain times of the year, we need extremely large numbers of these resources.
We also had other automated tasks that we wanted to perform. We wanted to do code linting (automated checking of code style) before a PR was tested. We wanted to check spelling of documentation. And we wanted these tasks to feed back into GitHub as automated comments and specific code review status markers, informing contributors not just that a problem occurred - but what problem occurred, and where in their code.
We also wanted to manage pipeline builds - there's no point in doing a full test of multiple versions of Python once you've established the tests are failing on one version. And there's no point testing at all if there are code style problems.
We also wanted to do things that weren't just testing. We wanted to check that contributor agreements have been signed. We wanted to automate deployment of websites and documentation.
What we had wasn't just a CI problem. It was a problem where we wanted to automatically run arbitrary code, in a safe way, in response to a GitHub event.
I've been trying to find a CI service that can meet our needs for over a year. But over the last year, a few thoughts started to congeal in my head.
- Amazon provides a API (EC2) that allows you to spool up machines of varying complexity (up to 64 CPUs, with almost 500GB of RAM), and pay by the minute for that usage.
- Docker provides the tools for configuring, launching, and running code in an isolated fashion
- Amazon also provides an API (ECS) to control the execution of Docker containers.
There's nothing specific about AWS EC2 or ECS either - you could just as easily use Linode and Kubernetes, or Docker Swarm, or Microsoft Azure... you just need to have the ability to easily spool up machines and run a Docker container. After all: a test suite is just a Docker container that runs a script that starts your test suite. A linting check is a Docker container that runs a script that lints your code. A contributor agreement check is a Docker container that checks the metadata associated with a pull request.
All you need then is a website that can receive GitHub event notifications, and start Docker containers in response.
At the start of July, I found myself between jobs, and uttered the fateful question "How hard could it be?" And so, today, I'm announcing BeeKeeper - BeeWare's own CI service.
BeeKeeper deploys as a Heroku website, written using Django. After configuring it with Github and AWS credentials, it listens for Github webhooks. When a Pull Request or Push is detected, BeeKeeper creates a build request; that build request inspects the code in the repository looking for a beekeeper.yml configuration file. That configuration file describes the pipeline of tasks that will be performed, and for each task, the type of machine that should be used, any environment variables that are required, and the Docker image that will be used.
BeeKeeper also allows the site admin to describe what resources will be used to satisfy builds. A task can say it needs a "High CPU" instance; but the BeeKeeper instance can determine what "High CPU" means - is it 4 CPUs or 32? When those machines are spooled up, how long will they be allowed to sit idle before being shut down again? How many machines should be sitting in the pool permanently? And what is the upper limit on machines that will be started?
A companion tool to BeeKeeper is Waggle. Waggle is a tool that prepares a local definition of a task so it can be used by BeeKeeper - it compiles the Docker image, and uploads it into ECS so that it can be referenced by tasks. (It's called "Waggle" because when worker bees discover a good source of nectar, they return to the hive and do a waggle dance that tells other bees how to find that source).
We've also provided a repository called Comb (named after honey comb, the place bees store all the nectar they find) that defines the task configurations that a BeeKeeper instance can use. We've provided some simple definitions as part of the base Comb repository; each BeeKeeper deployment should have one of these repositories of it's own.
There's still a lot of work to do, but we're already using BeeKeeper to Batavia and VOC, and the upcoming PyCon AU sprints will be our first outing under high-load conditions. Some back-of-envelope calculations predict that for around $50, we'll be able to provide enough CPU resources for each test run to complete running in 10 minutes or less, supporting a sprint of dozens of people.
Although BeeKeeper was written to meet the needs of the BeeWare project, it's an open source tool available for anyone to use. If you'd like to take BeeKeeper for a spin, come along to the sprints, or check out the code on GitHub.
BeeKeeper is also an example of the sort of product you'd see more of if BeeWare development was funded full time. I was able to build BeeKeeper because I had a spare couple of weeks between jobs. There is no end to the tools and libraries like BeeKeeper and Waggle that could be built to support the software development process - all that is missing is the resources needed to develop those tools. If you'd like to see more tools like BeeKeeper in the world, please consider joining the BeeWare project as a financial member. Every little bit helps, and if we can reach a critical mass of supporters, I'll be able to start working on BeeWare full time.

To record the work that I will be doing throughout this course, I will be coding developing this website using html. I will also be using css to style the pages and javaScript where appropriate. I decided to use divs in the development of the site so that I can keep my code organised. This also helps me simplify my css code.
Our first project was, using only sheets of newspaper and tape, to build the tallest tower that could also withstand airflow from a fan. Our group decided to build a tripod base for the tower and add as many rolls of newspaper we could on top of the base. We managed to get a stable tower with 3 rolls of newspaper above the tripod base.

MDOF Systems
Multiple degrees of freedom linear systems are very simple to study if we adopt a matrix notation for the equation of motion...
- Vectorial equation of dynamic equilibrium.
- Linear relationship between displacement, acceleration vector and elastic, inertial force vector written in terms of a matrix product.
- Homogeneous equation of motion, equation of frequencies, eigenvalues and eigenvectors.
- Modal superposition.

The linear address corresponds to the address of the least-significant byte of the referenced memory data. When a memory address is indicated, the 8 bytes of data at memory location m64 are loaded. When the register-register form of this operation is used, the lower half of the 128-bit source register is duplicated and copied into the 128-bit destination register. See Figure 3-24.

Class Detail
exports.Integer(bits, sign)
Constructs a two's-complement integer an array containing bits of the
integer in 32-bit (signed) pieces, given in little-endian order (i.e.,
lowest-order bits in the first piece), and the sign of -1 or 0.
See the from* functions below for other convenient ways of constructing
exports.Integers.
The internal representation of an integer is an array of 32-bit signed
pieces, along with a sign (0 or -1) that indicates the contents of all the
other 32-bit pieces out to infinity. We use 32-bit pieces because these are
the size of integers on which Javascript performs bit-operations. For
operations like addition and multiplication, we split each number into 16-bit
pieces, which can easily be multiplied within Javascript's floating-point
representation without overflow or change in sign.
- Parameters:
-
{Array.
} bits - Array containing the bits of the number.
- {number} sign
- The sign of the number: -1 for negative and 0 positive.

Introduction¶
This online resource serves as a guide for professors/instructors that wish to adopt a data science classroom environment. These suggestions are based off of UC Berkeley’s experience teaching introductory data science courses (i.e. Data 8) on campus since 2015. For a guide on the pedagogical and curriculum considerations, there is a separate guide here.
This guide is written with all levels of technical understanding in mind, so even if you are new to creating a computational course, this guide is for everyone!
What is Data 8?¶
Data 8 is a “Foundations in Data Science” course taught for first year students at UC Berkeley. It combines principles/skills in statistics, programming, inference, modeling, hypothesis testing, visualization, and exploration. It provides a foundation in the many fields encompassed by “data science”, and gives students a practical introduction to the field. For a more in-depth description of the topics taught, please reference the separate pedagogy guide.
Creating a data science course from first-principles requires considerable advances in the technology available to instructors. In creating Data 8, the development team has worked closely with members of the open-source community, and has contributed to or adopted many open source projects. The goal driving development of technology for Data 8 is to develop an open platform of which Berkeley happens to be the first user.
As such, most of these components are freely available to the educational community, and we welcome others to adopt these tools for their own uses and become contributors to these projects over time.
Brief Outline¶
The following is an outline of the technical pieces that go into running Data 8. It is broken down by activity/need so that it might be most useful for others hoping to accomplish the same goals.
JupyterHub¶
Quick Link to Jupyterhub Intro
Data 8 started with 60 students in Fall 2015, and now has 1350 students as of Spring 2020. The course operates on a scale and level of complexity that required several technological improvements to our current teaching toolset. The Data 8 team worked closely with various open-source projects in order to contribute to tools that are broadly useful.
Autograding¶
Quick Link to Autograding Intro
Automating the grading of assignments within a Jupyter environment has been made simpler in recent years with the implementation of several open-source software solutions. These strides towards automated solutions save professors and instructors the long hours of grading assignments manually. This chapter serves as a guide towards choosing one that best fits a course’s scale and requirements.


The Peaks at the Pinnacles
The Pinnacles at Silver Star Mountain Resort are at the 'Peak' of construction.
In response to increasing demand for accommodations at the world-renowned North Okanagan ski hill, The Pinnacles Suites is constructing six, three-storey townhomes, called The Peaks.
Opening in January 2020, the new 2000-plus-square-foot townhomes sleep up to 10 people and offer prime ski-in, ski-out access to the slopes and breathtaking views over the village to the Monashee Mountains.
“As rental accommodations become harder to find on the mountain, people are very excited about these new townhomes and already inquiring about reservations for January,” said Destanne Norris, Pinnacles Suites general manager. “In addition, many families and groups prefer our larger suites where they can all stay together, and even bring their dog.”
Constructed by Pasechnik Construction of Vernon and Maddocks Construction of Armstrong, the townhomes have tandem garages and are adjacent to the existing Pinnacles Suites. The townhomes are fully furnished with deluxe amenities including high ceilings, full kitchen and dining area with covered deck, slate fireplace, three bedrooms, 2.5 baths including full ensuite in the master, flat screen TVs, washer/dryer, and private, heated patio with a six-person hot tub.
In keeping with the Pinnacles Suites strata complex, the townhomes are privately owned.
Only two units are remaining and owners can choose to live in their suites full time, lock and leave, or put them into the rental management pool for periods when they are unoccupied
There is no speculation tax in the North Okanagan and all come with a 10 year warranty.
The Peaks is the last and final phase of development at the Pinnacles which was started when a group of ski patrollers bought the day lodge from the resort in the mid-1980s.
They converted it into suites. In 1991, they added on to the central lodge by building three-story suites on the west wing, and then in 2001, the Pinnacles Slopeside townhomes on the east were constructed. Pinnacles Suites manages the rentals and has in-house housekeeping and front-desk staff.

Before getting too far, it is important to verify several things about the target application.
It is absolutely essential that the battery management system has at least one method to turn off the battery charger if one is used. It is strongly recommended to achieve this by connecting the Charger Safety Relay (See: Relay Settings [Link target "param_enabled_relays" not found] for how to enable it). Failure to provide the BMS with a means to turn off the charger can result in damage to the battery pack should the charger fail to turn itself off by its own means.
It is also essential for there to be some method for the battery management system to enforce current limits either through relays (See: Relay Settings [Link target "param_enabled_relays" not found] or through digital communication (See: CANBUS).

This demo is a fictious video-streaming service that demonstrates several aspects of IRMA. When you become IRMATube “member” you receive membership attributes. Subsequently, you can use these to watch (trailers of) movies on the IRMATube main page.
In particular, the IRMATube demo illustrates the following aspects of attribute-based authentication.
Upon becoming member of IRMATube you receive two attributes: one which simply proves that you are a member, and one which contains a personal membership number. When you wish to watch a movie, only your membership attribute is requested, not the membership number that identifies you: you only prove that you are a member, not who you are.
In a more elaborate and realistic scenario you may want to reveal your membership number too in case you want a movie to be added to your profile. That is not included in the current version of the IRMATube demo.
Some of the movies on IRMATube have an age limit. When you wish to watch those movies, you have to reveal not only your IRMATube membership attribute, but also your age limit attribute. (These attributes can be obtained here or here.)

Working with AWS Lambda function metrics
When your function finishes processing an event, Lambda sends metrics about the invocation to Amazon CloudWatch. You can build graphs and dashboards with these metrics in the CloudWatch console, and set alarms to respond to changes in utilization, performance, or error rates.
This page describes the Lambda function invocation, performance, and concurrency metrics available on the CloudWatch console.
Viewing metrics in the CloudWatch console
You can use the CloudWatch console to filter and sort function metrics by function name, alias, or version.
To view metrics in the CloudWatch console
-
Open the Metrics page
( AWS/Lambda
namespace) on the CloudWatch console. -
Choose a dimension.
-
By Function Name (
FunctionName
) – View aggregate metrics for all versions and aliases of a function. -
By Resource (
Resource
) – View metrics for a version or alias of a function. -
By Executed Version (
ExecutedVersion
) – View metrics for a combination of alias and version. Use theExecutedVersion
dimension to compare error rates for two versions of a function that are both targets of a weighted alias. -
Across All Functions (none) – View aggregate metrics for all functions in the current AWS Region.
-
-
Choose metrics to add them to the graph.
By default, graphs use the Sum
statistic for all metrics. To choose a different statistic and
customize the graph, use the options on the Graphed metrics tab.
The timestamp on a metric reflects when the function was invoked. Depending on the duration of the execution, this can be several minutes before the metric is emitted. If, for example, your function has a 10-minute timeout, look more than 10 minutes in the past for accurate metrics.
For more information about CloudWatch, see the Amazon CloudWatch User Guide.
Types of metrics
The following section describes the type of metrics available on the CloudWatch console.
Using invocation metrics
Invocation metrics are binary indicators of the outcome of an invocation. For example,
if the function returns
an error, Lambda sends the Errors
metric with a value of 1. To get a count of the number of function
errors that occurred each minute, view the Sum
of the Errors
metric with a period of one
minute.
You should view the following metrics with the Sum
statistic.
Invocation metrics
-
Invocations
– The number of times your function code is executed, including successful executions and executions that result in a function error. Invocations aren't recorded if the invocation request is throttled or otherwise resulted in an invocation error. This equals the number of requests billed. -
Errors
– The number of invocations that result in a function error. Function errors include exceptions thrown by your code and exceptions thrown by the Lambda runtime. The runtime returns errors for issues such as timeouts and configuration errors. To calculate the error rate, divide the value ofErrors
by the value ofInvocations
. Note that the timestamp on an error metric reflects when the function was invoked, not when the error occurred. -
DeadLetterErrors
– For asynchronous invocation, the number of times Lambda attempts to send an event to a dead-letter queue but fails. Dead-letter errors can occur due to permissions errors, misconfigured resources, or size limits. -
DestinationDeliveryFailures
– For asynchronous invocation, the number of times Lambda attempts to send an event to a destination but fails. Delivery errors can occur due to permissions errors, misconfigured resources, or size limits. -
Throttles
– The number of invocation requests that are throttled. When all function instances are processing requests and no concurrency is available to scale up, Lambda rejects additional requests with TooManyRequestsException. Throttled requests and other invocation errors don't count asInvocations
orErrors
. -
ProvisionedConcurrencyInvocations
– The number of times your function code is executed on provisioned concurrency. -
ProvisionedConcurrencySpilloverInvocations
– The number of times your function code is executed on standard concurrency when all provisioned concurrency is in use.
Using performance metrics
Performance metrics provide performance details about a single invocation. For example,
the
Duration
metric indicates the amount of time in milliseconds that your function spends processing
an event. To get a sense of how fast your function processes events, view these metrics
with the
Average
or Max
statistic.
Performance metrics
-
Duration
– The amount of time that your function code spends processing an event. The billed duration for an invocation is the value ofDuration
rounded up to the nearest millisecond. -
IteratorAge
– For event source mappings that read from streams, the age of the last record in the event. The age is the amount of time between when the stream receives the record and when the event source mapping sends the event to the function.
Duration
also supports percentile statistics. Use
percentiles to exclude outlier values that skew average and maximum statistics. For
example, the P95 statistic
shows the maximum duration of 95 percent of executions, excluding the slowest 5 percent.
Using concurrency metrics
Lambda reports concurrency metrics as an aggregate count of the number of instances
processing events across a
function, version, alias, or AWS Region. To see how close you are to hitting concurrency
limits, view these
metrics with the Max
statistic.
Concurrency metrics
-
ConcurrentExecutions
– The number of function instances that are processing events. If this number reaches your concurrent executions quota for the Region, or the reserved concurrency limit that you configured on the function, additional invocation requests are throttled. -
ProvisionedConcurrentExecutions
– The number of function instances that are processing events on provisioned concurrency. For each invocation of an alias or version with provisioned concurrency, Lambda emits the current count. -
ProvisionedConcurrencyUtilization
– For a version or alias, the value ofProvisionedConcurrentExecutions
divided by the total amount of provisioned concurrency allocated. For example,.5
indicates that 50 percent of allocated provisioned concurrency is in use. -
UnreservedConcurrentExecutions
– For an AWS Region, the number of events that are being processed by functions that don't have reserved concurrency.


Leclerc blames himself for error, apologises to Ferrari
by AFPSAO PAULO: Charles Leclerc blamed himself and apologised to Ferrari on Saturday after qualifying fourth on the grid for Sunday’s Brazilian Grand Prix.
The Monegasque driver, who is set to take a 10-place penalty after taking a new engine, said he had made a mistake during his best lap, which had cost him three-tenths of a second, and wrecked his hopes of taking pole.
“I don’t think pole position was out of reach today,” said Leclerc. “But I am very disappointed with myself as I made a mistake which cost me three-tenths.
“I didn’t do the job in the car so ‘sorry to the team’, but with my grid penalty it was always going to be very tough.
“So, I will be in full-on attack mode tomorrow. I enjoy the first from the back and I will really try to ensure I do a good job for the team.”
Red Bull’s Max Verstappen claimed his second career pole for Red Bull and will start ahead of Leclerc’s team-mate four-time champion Sebastian Vettel on the front row.
Vettel said: “I had a bit a wobble in the exit of the last corner of my first run, but I think Max improved his time so fair play. It’s his pole.
“I am happy with the front row and look forward to see what we can do tomorrow in the race.
“We got better and better through this qualifying, which was the target and we were improving so we will see how it plays out.
“Red Bull and Mercedes look stronger in managing the tyres, but we have the speed and the power. I am cautiously optimistic – and it should be a good race.”

Orientation¶
Here we introduce you to the OKD orchestrator, guide you through its use and walk through one of the built-in standard AWS-based tutorial files. 1
Introduction¶
The OKD Orchestrator is a utility designed to simplify simple 2 RedHat OKD platform installations.
The OKD Orchestrator is an OpenRiskNet funded project 3 and the orchestrator has a number of roles: -
Definition of a deployment
Compilation of base operating system machine images
Provisioning of cloud-based compute instances
Deployment of the OKD platform
It achieves this through the use of Packer, Terraform and Ansible, all managed by a pair of simple Python-based command-line utilities and a high-level configuration file.
We are not going to discuss Packer, Terraform or Ansible in this orientation.
If you want to recreate this orientation’s deployment on AWS you will need: -
An AWS account and SSH keypair
Git to clone the OKD Orchestrator
Docker to run the OKD Orchestrator in Docker
Python (and a suitable virtual environment) to run the OKD Orchestrator from the command-line
A certbot/Let’s encrypt account if you want to enable also auto-generate SSL certificates
Familiarity with the unix command-line and shell
An internet connection
The more detailed guide that starts with the Getting Started document should provide you with all the necessary instructions.
Why do I need the OKD Orchestrator?¶
You don’t.
You just need an OpenShift OKD inventory file and some hardware.
Create an inventory file…
The configuration of OKD is, understandably, complex. There are lots of parts to OKD and a myriad of configuration parameters spread over pages of some quite extensive documentation. OKD is no different if you don’t understand it then configuring it will be difficult as one depends on the other.
Anyway, you’re through the documentation and you’ve created your OKD inventory file (in an extended-ini or YAML format) knowing what you need to do to create your compute instances…
Create your hardware…
If you’ve used a cloud provider’s built-in tools you’ll appreciate that creating precisely what you need for the network topology can be challenging.
Each provider uses their own terms for the network components (security groups in AWS, firewalls in GCE), which are often connected differently (groups connect to instances in AWS but firewalls connect to a networks in GCE).
The good news is that if you’re tied to one provider for business reasons then at least your task is reduced somewhat - there’s just one learning curve to climb.
Run the installer…
Clone the OpenShift repo on the cloud machine
Switch the a tagged release
Install Ansible
Run the installer
But…
The OKD Orchestrator tries eliminate these complexities by: -
Consolidating both cluster and OKD configuration definitions into one human-readable configuration file
Providing simplified create and destroy* command-line utilities so that you can create your OKD installation and then quickly tear it down
Trying to make the process cloud-agnostic by providing built-in Terraform orchestration for key providers
The OKD Orchestrator also supports advanced features like customer-specific (on-premise) or bare-metal installations and post-OKD playbooks for the installation of additional applications (like the ACME Controller certificate provisioner):
"Genius is making complex ideas simple, not making simple ideas complex."
-- Albert Einstein
So, how do I use the orchestrator?¶
The orchestrator is normally executed using a Docker container launched from within the project root of a clone (or fork) of the orchestrator GitHub repository. The Docker container is essentially a batteries included approach - where all the tools are built-in.
If you are comfortable working with your own copies of the underlying tools (i.e. Packer and Terraform) and Python virtual environments, you can run the orchestrator directly from the command-line 4.
We’ll explore the basics of the orchestrator by reproducing the built-in configuration for a small AWS-based installing called standard-aws-frankfurt-3-11 using the container image distribution of the OKD orchestrator, which contains all the tools you need.
Once you have cloned (or forked) the OKD Orchestrator 4 distinct steps are required to install OKD on a new cloud environment: -
Define a deployment
Compiling machine images
Provisioning physical compute instances
Deployment of the OKD platform
Assuming that you have a container runtime like Docker installed your next step is to clone the OKD Orchestrator to our desktop using Git:
$ git clone https://github.com/InformaticsMatters/okd-orchestrator.git
$ cd okd-orchestrator
This will provide us with the create (and destroy) utility and the example deployments including the standard AWS deployment we’re illustrating here and the container we’ll run will provide us with all the additional tools including a Python environment.
As well as this high-level orientation there is a more detailed discussion of the orchestrator that starts with the Getting Started document.
A discussion of the directories and layout of the OKD Orchestrator can be found in the accompanying Architecture document.
Step 1 - DEFINE a deployment¶
Here we define the installation (topology) and provide some key (secret) material that consists of: -
A deployment configuration
A set of environment variables in an environment file
An SSH key-pair
Deployments are defined in a YAML file in the OKD Orchestrator’s
deployments
directory and variables required to interact with your cloud provider setup in asetenv.sh
file. The deployment file (configuration.yaml
) resides in a sub-directory and allows you to define the physical and software topology of the OKD cluster.The environment file (a shell-script called
setenv.sh
) lives in theprovider-env
directory, where you will find templates of required variables for the supported cloud providers. The setenv-aws-template is a good example of what might be expected in terms of environment variables.The SSH keypair (kept in the root of the project) allows the orchestrator to securely communicate with the physical instances it will be creating.
Anatomy of a deployment configuration¶
Before we orchestrate the built-in example we can spend some time exploring the anatomy of the deployment configuration, the YAML file that describes the cluster hardware you desire and the OKD software that will be installed.
You can find a discussion of the deployment configuration in the Anatomy of a Deployment Configuration document, or you can inspect the built-in compact-aws-frankfurt-3-11 configuration that has comprehensive in-line documentation.
Step 2 - COMPILE a Machine Image¶
In this initial step, which you’d run once for each cloud-provider and region (depending on provider), we use Yacker (a YAML wrapper around the HashiCorp Packer utility) to compile a machine image suitable for OKD.
Its role is to create an operating system (machine) image that contains all the extra bits needed by OKD. 5
The compilation takes place on a temporary machine created in your provider’s network. The machine is small but may still incur a cost depending on the cloud-provider’s pricing policy.
To compile you simply run the yacker build
command from within the
orchestrator container image:
$ ./okdo-start.sh
$ yacker build yacker/3.11/aws/okd.yaml
$ yacker build yacker/3.11/aws/bastion.yaml
A detailed introduction to compiling machine images can be found in the document Compiling Machine Images.
Once complete the resultant machine images are saved in your cloud account and illustrated in the following diagram.
The default Yacker build for AWS will build machine images for the Frankfurt
(eu-central-1
) region.
Step 3 - PROVISION the hardware¶
With machine images built, your next step relies on the deployment configuration that you have defined.
The configuration file is used by the create.py
utility’s --cluster
option to form the physical compute instances that will be used by OKD.
From within the OKD Orchestrator container you’d typically run the
following, which instructs the create
utility to create a cluster
based on the configuration directory standard-aws-frankfurt-3-11
:
$ ./create.py --cluster standard-aws-frankfurt-3-11
Illustrated in the diagram below, the by-product of the provisioning process is: -
A network of cloud-based hardware
An inventory file for use in the next stage
A copy of the OKD Orchestrator on the Bastion machine, which includes the deployment configuration, inventory and other key files
The orchestrator achieves this by compiling a set of Terraform templates that represent your hardware needs and then utilises Terraform to instantiate all the physical components required to host your environment. This typically involves instantiating a large number of components (networks, firewalls, machines and volumes).
The AWS cluster components for our _standard_ configuration looks something like this: -
Step 4 - DEPLOY OpenShift OKD¶
With the cluster created the final step, installing the OKD platform software, takes place on the Bastion machine (or Master if the Master is also acting as a Bastion). A copy of the orchestrator, deployment and all relevant files have been placed on it by the provisioning step.
The orchestrator exposed the address of the Bastion at the end of the cluster instantiation, so you simply need to hop onto it and run the final stage from there:
$ ssh centos@<bastion-address>
$ cd okd-orchestrator
$ ./create.py
At the end of this stage your OKD platform has been installed and configured.

Deleting your cluster¶
We’re not going to go into detail here but, once you’re done with your
cluster, the OKD orchestrator comes with a handy destroy
utility.
It doesn’t uninstall OKD it simply deletes all of the cloud objects and any volumes created created by the underlying OKD platform. Your just need to run the following from your OKD desktop container:
$ ./destroy.py standard-aws-frankfurt-3-11
Further reading¶
You can read more about the orchestrator by following the Getting Started guide and a number of more advanced features are covered in the Advanced Topics section.
Footnotes
- 1
Depending on your network performance the AWS configuration should be ready to use in about 30 minutes.
- 2
Single Master, single infrastructure and multiple compute nodes. i.e. devoid of load-balancing capabilities and zone redundancy but sufficient to experiment with complex projects
- 3
Some icons in this presentation are produced by Freepix under the Creative Commons BY 3.0 licence.
- 4
The documentation assumes that you will be using the containerised OKD
- 5
Even with the latest OKD it isn’t installed on an “out-of-the-box” operating system - some stuff needs to be added (typically to CentOS)

A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions.
You can divide up your code into separate functions. How you divide up your code among different functions is up to you, but logically the division is such that each function performs a specific task.
A function declaration tells the compiler about a function's name, return type, and parameters. A function definition provides the actual body of the function.
The C standard library provides numerous built-in functions that your program can call. For example, strcat() to concatenate two strings, memcpy() to copy one memory location to another location, and many more functions.
A function can also be referred as a method or a sub-routine or a procedure, etc.
The general form of a function definition in C programming language is as follows −
return_type function_name( parameter list ) { body of the function }
A function definition in C programming consists of a function header and a function body. Here are all the parts of a function −
Return Type − A function may return a value. The return_type is the data type of the value the function returns. Some functions perform the desired operations without returning a value. In this case, the return_type is the keyword void.
Function Name − This is the actual name of the function. The function name and the parameter list together constitute the function signature.
Parameters − A parameter is like a placeholder. When a function is invoked, you pass a value to the parameter. This value is referred to as actual parameter or argument. The parameter list refers to the type, order, and number of the parameters of a function. Parameters are optional; that is, a function may contain no parameters.
Function Body − The function body contains a collection of statements that define what the function does.
Given below is the source code for a function called max(). This function takes two parameters num1 and num2 and returns the maximum value between the two −
/* function returning the max between two numbers */ int max(int num1, int num2) { /* local variable declaration */ int result; if (num1 > num2) result = num1; else result = num2; return result; }
A function declaration tells the compiler about a function name and how to call the function. The actual body of the function can be defined separately.
A function declaration has the following parts −
return_type function_name( parameter list );
For the above defined function max(), the function declaration is as follows −
int max(int num1, int num2);
Parameter names are not important in function declaration only their type is required, so the following is also a valid declaration −
int max(int, int);
Function declaration is required when you define a function in one source file and you call that function in another file. In such case, you should declare the function at the top of the file calling the function.
While creating a C function, you give a definition of what the function has to do. To use a function, you will have to call that function to perform the defined task.
When a program calls a function, the program control is transferred to the called function. A called function performs a defined task and when its return statement is executed or when its function-ending closing brace is reached, it returns the program control back to the main program.
To call a function, you simply need to pass the required parameters along with the function name, and if the function returns a value, then you can store the returned value. For example −
#include <stdio.h> /* function declaration */ int max(int num1, int num2); int main () { /* local variable definition */ int a = 100; int b = 200; int ret; /* calling a function to get max value */ ret = max(a, b); printf( "Max value is : %d\n", ret ); return 0; } /* function returning the max between two numbers */ int max(int num1, int num2) { /* local variable declaration */ int result; if (num1 > num2) result = num1; else result = num2; return result; }
We have kept max() along with main() and compiled the source code. While running the final executable, it would produce the following result −

If a function is to use arguments, it must declare variables that accept the values of the arguments. These variables are called the formal parameters of the function.
Formal parameters behave like other local variables inside the function and are created upon entry into the function and destroyed upon exit.
While calling a function, there are two ways in which arguments can be passed to a function −
| S.N. | Call Type & Description |
|---|---|
| 1 | Call by value
This method copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function have no effect on the argument. |
| 2 | Call by reference
This method copies the address of an argument into the formal parameter. Inside the function, the address is used to access the actual argument used in the call. This means that changes made to the parameter affect the argument. |
By default, C uses call by value to pass arguments. In general, it means the code within a function cannot alter the arguments used to call the function.

It is a joining a group of people together to program and solve solutions. By seperateing into distinct roles of Driver and Navigator.
Pair programming limits errors, a second set of eyes cleans up the process, it expands the number of potential solutions by taking in a different perspective. It is what DBC is all about.
DRIVER: Someone who litterally writes out the code. NAVIGATOR: Directs the driver on a certain part of the code, and lays out the steps to solve the problems.
