Avant de commencer

Chrono : 30 minutes. Il démarre quand le cluster est prêt et continue si vous fermez l’onglet.
Notation : environ toutes les 5 minutes, et le bouton Grade note tout de suite.
Inactivité : 20 minutes sans frappe ferment le cluster. Un compte à rebours de 90 secondes s’affiche d’abord sur la page. « Je suis là », ou une touche dans le terminal, le remet à zéro.
Le terminal est prêt quand il affiche la ligne verte « You're in. The cluster is ready. » Session connected veut seulement dire que la socket est ouverte. Ensuite, kubectl get nodes doit lister un nœud.

Question 1 (6 points) — InitContainer, Volumes

- 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

Add an emptyDir volume backed by memory (tmpfs) instead of the node's
disk, and mount it in sorrel at /paint.
