Question #13 (Topic: Single Topic)
SIMULATION
Context
An existing Pod needs to be integrated into the Kubernetes built-in logging architecture (e.g.
kubectl logs). Adding a streaming sidecar container is a good and common way to accomplish this requirement.
Task
Add a sidecar container named sidecar, using the busybox image, to the existing Pod big-corp-app. The new sidecar container has to run the following command:
Use a Volume, mounted at /var/log, to make the log file big-corp-app.log available to the sidecar container.
