title: My internship at Red Hat
|
|
---
|
|
|
|
I have been contributing to open source for the last 3 years and Red Hat
|
|
was one of the companies that I was very fond of. I must say all my
|
|
contributions and consistency paid off, and I made it to the Red Hat as
|
|
a DevTools intern. This post is about onboarding and how I prepared
|
|
myself for working on the actual project.
|
|
|
|
On the first day of my internship, I met two amazing teammates
|
|
[Saytam](https://github.com/) and [Utkarsh](https://github.com/). We
|
|
were also introduced to a Senior Software Engineer [Piyush
|
|
Garg](https://github.com) who later mentored us. The initial few
|
|
meetings were more on the introduction and what to learn topics. Before
|
|
I jump into more details let me explain first what does a **DevTools
|
|
Developer/Engineer** do?
|
|
|
|
## What does a DevTools Developer/Engineer do?
|
|
|
|
From [MDN Web
|
|
Docs](https://developer.mozilla.org/en-US/docs/Glossary/Developer_Tools)
|
|
**Developer tools (or "development tools" or short "DevTools") are
|
|
programs that allow a developer to create, test, and debug software.**
|
|
At RedHat, a lot of open source developer tools of industry standards
|
|
are developed. There are many, OpenShift, Tekton, CodeReady containers,
|
|
and many more.
|
|
|
|
## Learning on the Go
|
|
|
|
There was a lot of learning and still a lot to learn. In a meeting with
|
|
my manager [^1] Pradeepto Bhattacharya, I was told that I will be working on
|
|
TektonCD or OpenShift Pipelines, and both of them require a sound
|
|
knowledge of Golang, CI/CD, Containers, Docker, and Kubernetes. I was
|
|
familiar with CI/CD, containers, and Docker but never used Golang and
|
|
Kubernetes. We were provided plenty of good resources and my teammates
|
|
also helped with many awesome resources. I am listing all the resources
|
|
with their category.
|
|
|
|
### Go Programming Language
|
|
|
|
One of Golang's biggest advantages is that it offers the clarity and
|
|
ease of use that other languages lack. Golang's advantages make it easy
|
|
for new programmers to quickly understand the language and for seasoned
|
|
veterans to easily read each other's code.

|
|
### Docker
|
|
|
|
Docker takes away repetitive, mundane configuration tasks and is used
|
|
throughout the development lifecycle for fast, easy, and portable
|
|
application development - desktop and cloud. Docker's comprehensive
|
|
end-to-end platform includes UIs, CLIs, APIs, and security that are
|
|
engineered to work together across the entire application delivery
|
|
lifecycle.

### Kubernetes
|
|
|
|
|
|
|
|
**Kubernetes** is the Greek word for a ship's captain. We get the words
|
|
Cybernetic and Gubernatorial from it. The Kubernetes project focuses on
|
|
building a robust platform for running thousands of containers in
|
|
production.

## *Not so Minimal* Tekton Server
|
|
|
|
In late January, we were asked to implement our learnings and deep dive
|
|
into Kubernetes and TektonCD through an assignment project. Soon we
|
|
realized that whatever we were learning so far was not even close to
|
|
what we were going to implement. We were given a document containing the
|
|
requirements of the applications we were supposed to create along with
|
|
all the documentation and architectural diagrams.
|
|
|
|
The application was called **Minimal Tekton Server**. It is a set of
|
|
three different applications, i.e a server, a CLI, and a dashboard. In
|
|
short, this application is supposed to *listen to custom resources being
|
|
created and then transfer the request to Tekton API to create the
|
|
corresponding resource on the OpenShift/Kubernetes cluster.*
|
|
|
