EX280 Application Deployment And Lifecycle Practice Question
An administrator needs to perform a canary deployment strategy using standard OpenShift Deployment resources (not DeploymentConfigs). What is the standard Kubernetes/OpenShift native mechanism to route a small percentage of traffic to the canary deployment?
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
✓
Using an OpenShift Route with weighted backend services pointing to stable and canary Services
Standard Deployments do not have native percentage-based traffic splitting; an administrator must use a Service with multiple underlying selector labels alongside a Service Mesh, Ingress controller, or an OpenShift Route with weight configurations pointing to distinct Services. Specifically, OpenShift Routes support splitting traffic via weighted backends across multiple Services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Setting the traffic-split annotation on the Deployment resource
Why it's wrong here
Deployments do not natively interpret traffic-split annotations for external routing without a mesh or ingress controller.
- ✓
Using an OpenShift Route with weighted backend services pointing to stable and canary Services
Why this is correct
OpenShift Routes support weighted traffic distribution across multiple Services to implement canary routing.
- ✗
Configuring weight parameters directly in the Deployment spec rollingUpdate strategy
Why it's wrong here
Deployment rollingUpdate strategy only controls pod creation rates, not external traffic routing weights.
- ✗
Enabling canary mode in the ImageStream tag metadata
Why it's wrong here
ImageStream tags do not control traffic routing weights between deployments.
