CGOA Gitops Patterns Practice Question
Your organization uses the App-of-Apps pattern in Argo CD to manage hundreds of microservices. You need to ensure that when a developer updates a repository structure, the root application automatically discovers and syncs new child applications without manual intervention. Which feature should be enabled in the Application resource?
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
✓
Enable automated sync policy with self-healing and allow-empty
The self-healing and automated sync policies, combined with directory recursion, allow the App-of-Apps pattern to maintain state automatically.
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 the 'ignoreDifferences' field for the child application manifests
Why it's wrong here
IgnoreDifferences prevents synchronization rather than enabling discovery.
- ✓
Enable automated sync policy with self-healing and allow-empty
Why this is correct
Self-healing ensures the live state matches the desired state defined in Git, while automatic sync ensures new directories are picked up.
- ✗
Set the sync policy to 'manual' and use a post-sync hook
Why it's wrong here
Hooks are for orchestration, not for dynamic application discovery.
- ✗
Configure a manual webhook trigger on the root application
Why it's wrong here
Manual triggers defeat the purpose of automated GitOps workflows.
