GitOps is a software development methodology that uses Git as a single source of truth for both application code and infrastructure configuration. In GitOps, all changes to the application and its infrastructure are made via Git commits and pull requests, which trigger automated pipelines that deploy those changes to the live environment.

The basic GitOps workflow involves the following steps:

  1. Developers make changes to application code or infrastructure configuration in a Git branch.
  2. A pull request is created, and the changes are reviewed and approved.
  3. Automated tests are run, and if they pass, the changes are merged into the main branch.
  4. A Git webhook triggers a pipeline to deploy the changes to the live environment.
  5. The deployment is monitored, and if any issues arise, they are rolled back using Git.

By using Git as the source of truth, GitOps provides several benefits such as improved collaboration, version control, and auditability of changes. It also helps to reduce manual errors, ensures consistency across environments, and enables the deployment of changes in a safe and predictable manner.
