This is a bash script that is intended to automate the process of setting up a DevOps environment on a Ubuntu-based operating system. It can be used to set up a development environment on a new machine, ensuring that all the necessary tools and configurations are in place. This can be particularly useful for developers working on a team, as it ensures that everyone is using the same tools and configurations.

The script starts by updating the package index, which is necessary to ensure that the system is aware of the latest versions of packages that are available for installation.
After updating the package index, the script installs the Zsh shell, which is a popular alternative to the default Bash shell on Linux systems. The script then proceeds to install and configure a number of other tools that are commonly used in DevOps workflows:
Terraform, infrastructure as code tool for provisioning and managing cloud infrastructure.
Ansible, a configuration management and automation tool.
Git, a distributed version control system that is used for managing the source code of software projects
Docker, a platform that allows developers to easily create, deploy, and run applications in containers.
Kubernetes, an open-source container orchestration system.
Helm, a package manager for Kubernetes.
AWSCLI, command line interface for Amazon Web Services.
Python3, a popular programming language.
kubie, a tool that makes it easier to switch between different Kubernetes contexts and namespaces.
Once the tools have been installed, the script adds them to the PATH environment variable, which allows them to be easily executed from anywhere on the system.
The script also creates aliases for these tools, which are shortcuts that can be used to run the tools with certain options or arguments. For example, the script creates an alias “k” for kubectl, which allows the user to run kubectl commands by typing “k” instead of “kubectl”.
In addition, the script adds a number of other useful alias commands for different tasks. for example,
“kg” for “kubectl get”
“kgp” for “kubectl get pods -o wide”
“kgs” for “kubectl get service”
“kgpv” for “kubectl get pv”
“kgpvc” for “kubectl get pvc”
Finally, the script sets up Zsh autocomplete, which allows the user to press the TAB key to automatically complete commands and options as they are typed.
Overall, this script is intended to automate the process of setting up a development and operations environment on Ubuntu and make the user more efficient by providing a set of useful alias commands.
