CGOA Gitops Patterns Practice Question
You want to promote a microservice from staging to production using the 'Git Branch' strategy. Which configuration allows you to ensure the exact same container image SHA is used across both environments?
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 a common Helm chart with environment-specific values files.
Using image tags like 'latest' is non-deterministic. Referencing the specific SHA in the Git manifest for the production branch ensures consistency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manually update the container image using kubectl edit.
Why it's wrong here
Manual changes bypass the GitOps reconciliation loop and will be overwritten.
- ✓
Use a common Helm chart with environment-specific values files.
Why this is correct
Keeping the chart constant and varying the values (including the image SHA) is the standard GitOps practice for promotion.
- ✗
Use a different container registry for production.
Why it's wrong here
Registry location does not guarantee image consistency or content addressability.
- ✗
Change the image tag to 'production' in the deployment manifest.
Why it's wrong here
Mutable tags like 'production' can be overwritten, breaking GitOps immutability principles.
