What tools and scripts are used for process automation?

The following tools and scripts are often used for automating processes in DevOps:

• Scripts in Bash, Python, PowerShell — for writing simple and complex automated tasks.
• Ansible, Puppet, Chef — tools for configuration management and automatic deployment.
• Jenkins, GitLab CI/CD, Travis CI — continuous integration and delivery systems (CI/CD) that automate building, testing, and deployment.
• Terraform — for automating the creation and management of infrastructure.
• Docker and Kubernetes — for automating containerization and orchestration of applications.

An example of a simple Bash script for automatic updating and restarting a service:

#!/bin/bash
sudo apt update && sudo apt upgrade -y
sudo systemctl restart myservice

This approach helps reduce manual labor and increase the reliability of processes.
