Question 1 (6 points) — InitContainer, Volumes
Create a Pod ricochet in namespace flight:
- a container shuttle, image nginx:1.14.2
- an init container preflight, image busybox:1.36, that creates the
file /shared/ready before shuttle starts
- both containers mount the same emptyDir volume at /shared
Question 2 (7 points) — Job
Create a Job timonerie-run in namespace hangar:
- one container runner, image busybox:1.36, running the command
echo timonerie-ok
- the Job needs 3 successful completions, with at most 2 Pods running
in parallel
- the Job retries at most 2 times before it is marked failed
Question 3 (6 points) — CronJob
Create a CronJob boulon-tune in namespace workshop:
- schedule */5 * * * * (every 5 minutes)
- a new run must not start while the previous one is still running;
skip it instead
- only the last successful Job is kept in history
- one container droid, image busybox:1.36, running the command
echo tune
Question 4 (6 points) — Volumes
Create a Pod spray-paint in namespace workshop with one container
sorrel, image busybox:1.36, command sleep 1d.
Add an emptyDir volume backed by memory (tmpfs) instead of the node's
disk, and mount it in sorrel at /paint.
