One of several containers in a pod is marked as unhealthy after failing its livenessProbe many times. Is this the action taken by the orchestrator to fix the unhealthy container?

Solution: The controller managing the pod is autoscaled back to delete the unhealthy pod and alleviate load.
A . Yes
B . No

Answer: B

Explanation:

: = The livenessProbe is a mechanism that checks if the container is alive and healthy, and restarts it if it fails1. The orchestrator is the component that manages the deployment and scaling of containers across a cluster of nodes2. The action taken by the orchestrator to fix the unhealthy container is not to autoscale back and delete the pod, but to recreate the pod on the same or a different node3. This ensures that the desired number of replicas for the pod is maintained, and that the pod can resume its normal operation. Autoscaling back and deleting the pod would reduce the availability and performance of the service, and would not necessarily alleviate the load.

I hope this helps you understand the concept of livenessProbe and orchestrator, and how they work with Docker and Kubernetes. If you have any other questions related to Docker, please feel free to ask me.
