CGOA Gitops Patterns Practice Question
In a multi-cluster GitOps setup using Argo CD, you need to ensure that specific secrets are only synced to a production cluster. Which approach is the most secure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Argo CD 'Project' resource to limit which namespaces secrets can be synced to.
Using External Secrets Operator with cluster-specific namespaces or Argo CD Project-level restrictions allows you to segregate secret access effectively.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use Argo CD 'Project' resource to limit which namespaces secrets can be synced to.
Why this is correct
Argo CD Projects allow for strict destination constraints, ensuring secrets only reach authorized cluster destinations.
- ✗
Store secrets in Git as plain text and use a private repository.
Why it's wrong here
Storing secrets in plain text in Git is a major security violation.
- ✗
Use Helm post-render hooks to inject secrets at runtime.
Why it's wrong here
Post-render hooks are not designed for secure secret management and occur outside the GitOps state definition.
- ✗
Enable 'AllowClusterResources' in the global configuration.
Why it's wrong here
This broad permission would expose secrets to all clusters, violating the security requirement.
