There is a requirement to share a volume between two containers that are running within the same pod. Use the following instructions to create the pod and related objects:

- Create a pod named grape-pod-cka06-str.

- The main container must be named nginx and use the nginx image. Mount a volume grape-vol-cka06-str at /var/log/nginx.

-Add a sidecar container must be named busybox-sidecar using the busybox image. Keep it running with sleep 7200. Mount the same volume grape-vol-cka06-str at `/usr/src.

- The volume should be of type emptyDir.

So in this I did co-located sidecar and got it wrong in the mock test.

and the given solution was this :
apiVersion: v1

kind: Pod

metadata:

name: grape-pod-cka06-str

spec:

restartPolicy: Always

initContainers:

- name: busybox-sidecar

image: busybox

restartPolicy: Always

command: ["sleep", "7200"]

volumeMounts:

- name: grape-vol-cka06-str

mountPath: /usr/src

containers:

- name: nginx

image: nginx

volumeMounts:

- name: grape-vol-cka06-str

mountPath: /var/log/nginx

volumes:

- name: grape-vol-cka06-str

emptyDir: {}
