CGOA Gitops Patterns Practice Question
You are performing a Canary deployment using Argo Rollouts. You notice that the analysis template is failing even though the metrics are within range. What is the most common cause of this in a GitOps workflow?
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
✓
The Prometheus metric query does not match the 'args' passed from the Rollout object.
If the analysis template fails despite metrics being valid, the culprit is often an incorrectly configured 'provider' field pointing to the wrong Prometheus endpoint or incorrect authentication credentials within the secret referenced by the analysis run.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The analysis template is missing the 'rollback' flag.
Why it's wrong here
Rollback is a behavior, not a condition for template execution failure.
- ✓
The Prometheus metric query does not match the 'args' passed from the Rollout object.
Why this is correct
AnalysisTemplates rely on accurately passed arguments to correctly query the metrics provider.
- ✗
The Rollout image version is not updated in the Git repository.
Why it's wrong here
This would result in no deployment, not a failure of the analysis template itself.
- ✗
The ReplicaSet is failing to scale to the desired state.
Why it's wrong here
This is a scaling issue, not an analysis template execution error.
