Maximum resources a container can use
Determines when to restart containers in a pod
Checks if container is running; restarts if fails
Checks if container is ready to serve traffic
Inject a secret value as an environment variable
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
livenessProbe: Indicates if the container is running. If fails, kubelet kills the container and restarts it.
Correct matches: livenessProbe checks container health, readinessProbe checks service readiness, startupProbe checks application startup, and imagePullPolicy controls image pulling. Common confusions involve swapping definitions with restartPolicy.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
livenessProbe: Indicates if the container is running. If fails, kubelet kills the container and restarts it.
Why this is correct
Liveness probe checks if the container is alive; failure triggers restart.
readinessProbe: Indicates if the container is ready to serve requests. If fails, the pod is removed from service endpoints.
Why this is correct
Readiness probe controls traffic routing; failure removes pod from service.
startupProbe: Indicates if the container application has started. If fails, restarts before liveness/readiness probes take over.
Why this is correct
Startup probe delays liveness/readiness checks until the app starts successfully.
imagePullPolicy: Defines when to pull the container image (e.g., Always, IfNotPresent, Never).
Why this is correct
Image pull policy controls image download behavior.
imagePullPolicy: Defines the policy for restarting the container after exit.
Why it's wrong here
Incorrect — this describes restartPolicy, not imagePullPolicy.
restartPolicy: Defines when to pull the container image.
Why it's wrong here
Incorrect — this describes imagePullPolicy, not restartPolicy.
