GitOps Exercises: Intermediate (EN)
These exercises belong to the workshop level Intermediate. Every task requires traceable evidence: source, commit, desired state, rendered state, controller relationship, risk and recovery path.
Submission Format
Do not store production secrets. Document instead:
- commands used,
- relevant manifest excerpts,
- affected GitOps source and target environment,
- assessment of drift, promotion, rollback, RBAC and secrets,
- recovery or rollback path.
