GitOps Best Practices

1. Introduction

GitOps is a modern operational framework that uses Git as the single source of truth for declarative infrastructure and applications. This lesson covers essential practices to implement GitOps effectively.

2. Key Concepts

• Declarative Configuration: Use configuration files to define the desired state of your system.
• Version Control: Store all configurations in Git repositories.
• Continuous Deployment: Automatically deploy changes to production environments using CI/CD pipelines.
• Observability: Monitor the actual state of the system and ensure it matches the desired state.
