[Bug] CKAD 1 Question 6: Sidecar container should be under initContainers

[miriSch]

Describe the bug

In the first CKAD exam, the solution and the second check is wrong according to kubernetes documentation.

Environment (please complete the following):

Report in Depth

In the first CKAD exam, the solution places the sidecar container in spec.containers (https://github.com/sailor-sh/CK-X/blob/master/facilitator/assets/exams/ckad/001/answers.md#question-6-create-a-multi-container-pod-with-sidecar-logging-pattern) and also the check for the second subtask expects it there (

CK-X/facilitator/assets/exams/ckad/001/scripts/validation/q6_s2_validate_shared_volume.sh

Line 27 in eaa11c1

MOUNT_IN_CONTAINER2=$(kubectl get pod sidecar-pod -n troubleshooting -o jsonpath="{.spec.containers[1].volumeMounts[?(@.name==\"$VOLUME\")].mountPath}" 2>/dev/null)

).

According to the documentation https://kubernetes.io/docs/concepts/workloads/pods/sidecar-containers/#pod-sidecar-containers sidecar containers should be placed in spec.initContainers, so the solution and the checks are wrong.

Steps to reproduce

Expected Behavior

Checks passing, correct solution documented.

Actual Behaviour

The check "Pod has shared volume mounted in both containers" fails and the solution places the sidecar container under spec.containers
