Discussion
Arrange the stages of a rolling update in order.
1. new pods pass their readiness probes
2. the desired image in the Deployment is changed
3. old pods are terminated
4. the controller creates pods with the new image
Answer: A
Termination waits for readiness so that capacity is never lost during the update. A readiness probe that always passes defeats the protection entirely. Capacity is preserved throughout. Old pods wait for the new to be ready.
