# 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.

There was a lot of learning and still a lot to learn. In a meeting with
my manager 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.

### [Golang](https://go.dev/)

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](https://www.docker.com/)

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](https://kubernetes.io/)

**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.*
