Understanding GitOps: A Technical Deep Dive
GitOps transforms the deployment process by orchestrating infrastructure and application modifications using Git repositories. GitOps is based on four basic pillars:
Declarative Infrastructure as Code (IaC)
GitOps supports the concept of declarative IaC, which expresses infrastructure configurations as code in Git repositories. This technique assures consistency, repeatability, and traceability because the desired state of the infrastructure is well defined and versioned.
Continuous Integration/Deployment (CI/CD) Pipelines
GitOps uses CI/CD pipelines to automate the deployment process. Changes to the Git repository initiate automated workflows for building, testing, and deploying apps and infrastructure changes, enhancing agility and eliminating manual involvement.
Git
is the single source of truth in GitOps procedures. All configuration changes, including infrastructure modifications and application upgrades, are managed using Git, which serves as a centralized and auditable repository for collaboration and version control.
GitOps prioritizes observability and monitoring throughout the deployment process. Integrating with monitoring tools and employing Git-based workflows allows teams to gain visibility into changes, track performance metrics, and effectively troubleshoot issues, maintaining system reliability and stability.
