EX280 Application Deployment And Lifecycle Practice Question
You need to deploy a Node.js application from a Git repository using Source-to-Image (S2I) on OpenShift 4.14, and you want to ensure the build triggers automatically whenever a new image is pushed to the dependent base ImageStream. Which BuildConfig strategy and configuration element achieves this?
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
✓
Configure a Source build with an ImageChange trigger on the input ImageStreamTag.
Using the source strategy in a BuildConfig along with triggers of type ImageChange allows the build to automatically run when the referenced ImageStreamTag changes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a Docker build with a ConfigChange trigger on the DeploymentConfig.
Why it's wrong here
ConfigChange triggers restart deployments on configuration changes, not builds based on image updates.
- ✓
Configure a Source build with an ImageChange trigger on the input ImageStreamTag.
Why this is correct
An ImageChange trigger monitors the base ImageStreamTag and automatically initiates a new build when the base image updates.
- ✗
Configure a Pipeline build referencing a Tekton pipeline with manual execution parameters.
Why it's wrong here
Pipeline builds are not automatically driven by base ImageStream updates unless explicitly scripted in Tekton.
- ✗
Configure a Custom build with a GitHub webhook trigger referencing the source repository.
Why it's wrong here
Webhook triggers respond to code pushes in Git, not updates to dependent base images.
