GitOps Culture
1. Introduction
GitOps is a modern approach to managing infrastructure and application deployments using Git as a single source of truth. This culture emphasizes the use of version control systems to facilitate collaboration, automation, and continuous delivery.
2. Key Concepts
2.1 Definitions
- Infrastructure as Code (IaC): Managing infrastructure through code rather than manual processes.
- Continuous Delivery (CD): A software development practice where code changes are automatically prepared for a release.
- Pull Requests: A method of submitting contributions to a project using Git.
3. GitOps Workflow
3.1 Overview of the Workflow
The GitOps workflow typically involves the following steps:
graph LR
A[Code Change] --> B[Create Pull Request]
B --> C[Review & Merge]
C --> D[Automatic Deployment]
D --> E[Monitoring & Feedback]
E -->|Feedback| A
3.2 Step-by-Step Process
- Developers make changes to the application code.
- Create a pull request to merge changes into the main branch.
- Changes are reviewed and approved by peers.
- Upon merging, Continuous Integration (CI) pipelines are triggered.
- Automated deployment tools deploy the changes to the production environment.
- Monitoring tools provide feedback on the deployment's success.
4. Best Practices
4.1 Key Best Practices
- Use Git branches effectively to manage features and releases.
- Implement automated testing in the CI/CD pipeline.
- Maintain documentation for all infrastructure changes.
- Ensure rollback mechanisms are in place for failed deployments.
- Regularly review and refine the GitOps processes.
