Git & Scripting Skills
Automation is the heart of DevOps, and Version Control is its backbone. You need to move away from manual "click-ops" to code-driven automation.
1. Version Control with Git
Version control is a must-have. It helps track changes, makes teamwork easy, and integrates with CI/CD pipelines.
- Basic Commands:
git clone,git add,git commit,git push,git pull. - Branching: Understanding
main,feature-branches, and how to use Pull Requests (PRs) for code review. - Conflict Resolution: Knowing what happens when two people change the same file and how to fix it.
- Platforms: Get comfortable with GitHub, GitLab, or Bitbucket.
2. Programming & Scripting
As a DevOps engineer, you don't need to be a "Software Developer" in the traditional sense, but you must write code to automate tasks.
Scripting (The Fast Way)
- Bash (Linux): Used for quick automation tasks like installing software, moving logs, or checking server health.
- PowerShell (Windows): The equivalent for Windows-based environments.
Programming (The Scalable Way)
- Python or Go: Used for complex automation, interacting with Cloud APIs (like Boto3 for AWS), and writing custom scripts. Python is highly recommended for beginners due to its readability.
Data Formats (The "Language" of DevOps)
You must understand JSON and YAML. These are not programming languages, but they are the standard formats for configuration files in almost every DevOps tool (Kubernetes, Ansible, CloudFormation).
[!IMPORTANT] Pro Tip: Try making a small project and share it on GitHub to get hands-on experience with both Git and scripting.
