Welcome: Kubernetes Visualization and Kubectl Tricks

Hello, and welcome! This repository is part of a Sela Software Development Practices (SDP) lecture titled "Kubernetes Visualization and Kubectl Tricks". This is more than just a lecture—it's a journey through the fascinating world of Kubernetes, its visualization techniques, and some clever tricks for using kubectl.

The lecturers guiding you on this journey are Noam Amrani and Natali Cutic.

This repo builds upon our previous work on kind kubernetes dashboard, which you can find in this repository.

Now, buckle up as we dive into the depths of kubectl.

Kubernetes: Exploring kubectl

Welcome to this comprehensive journey into the world of kubectl, a versatile command-line tool for interacting with a Kubernetes cluster.

What is kubectl?

kubectl is a powerful CLI tool that is used to deploy, manage, and scale containerized applications using Kubernetes, an open-source container orchestration system.

Key Features

• Deploy and manage applications on Kubernetes
• Get insights into your application and cluster
• Create, update, and delete various Kubernetes resources
• Use labels to organize Kubernetes resources
• Auto-completion support for Bash and Zsh shells to save typing

Fun Fact: Did you know that kubectl supports autocompletion for Bash and Zsh? This can save you a lot of typing!

Installation

Before we proceed, it's important to ensure that you have kubectl installed on your system.

For detailed instructions on how to install kubectl, please refer to the official Kubernetes documentation.

Autocompletion in Bash and Zsh

To make your journey easier and more efficient, kubectl supports autocompletion for both Bash and Zsh shells. Here is how you can set it up:

Bash

Ensure bash-completion is installed. The procedures vary based on the Linux distribution:

# macOS
brew install bash-completion@2

# Ubuntu
apt-get install bash-completion

Once installed, add the following lines to your ~/.bash_profile file for kubectl autocompletion, For Zsh, add the completion script to your .zshrc file:

echo 'source <(kubectl completion bash)' >>~/.bash_profile
echo 'alias k=kubectl' >>~/.bash_profile
echo 'complete -F __start_kubectl k' >>~/.bash_profile
source ~/.bash_profile

Setting KUBE_EDITOR

You can set your preferred editor for Kubernetes like this:

echo "export KUBE_EDITOR=\"nano\"" >>  ~/.bash_profile

Setting Alias

It is very reomended to set an alias when working whith kubectl

echo "alias k=kubectl" >>  ~/.bash_profile

Next Steps

As we move forward, we will dive deep into each functionality that kubectl offers, providing practical examples that you can try out yourself.

Enjoy the journey!
