Version Control and Commit Tracking: I maintain a history of commits using Git. Each commit, branch, and pull request has a unique ID and meaningful message attached to it. This forms the basis for traceability - traceable chronology of changes, information about authors and rationale.
I also use automated logging and metadata tagging. Tools like Jenkins, GitLab CI, and GitHub Actions enable me to log all CI/CD events. For example, in a Build-Test-Deploy sequence, I assign a unique build ID to each build. This allows for centralized logging through platforms such as the ELK Stack or Splunk, which consolidate logs and make searching across any step in the pipeline easy and efficient.
Role-Based Access Control (RBAC) and Approval Gates: In the CI/CD platform, I have implemented RBAC so that only approved personnel can approve changes to the production. High-risk deployment approval gates introduce a human review step that provides a security layer and traceability. The audit logs are created with every access attempt and approval, thereby assisting us in compliance and security.
