Wrong Questions: First Attempt

Q1

Create a pod called secret-1401 in the admin1401 namespace using the busybox image. The container within the pod should be called secret-admin and should sleep for 4800 seconds.

The container should mount a read-only secret volume called secret-volume at the path /etc/secret-volume. The secret being mounted has already been created for you and is called dotfile-secret

I didn't create a PVC

Q2

A new deployment called alpha-mysql has been deployed in the alpha namespace. However, the pods are not running. Troubleshoot and fix the issue. The deployment should make use of the persistent volume alpha-pv to be mounted at /var/lib/mysql and should use the environment variable MYSQL_ALLOW_EMPTY_PASSWORD=1 to make use of an empty root password.

Important: Do not alter the persistent volume.

I created a volume instead of a secret volume, it differs

Q3

Print the names of all deployments in the admin2406 namespace in the following format: DEPLOYMENT CONTAINER_IMAGE READY_REPLICAS NAMESPACE <deployment name> <container image used> <ready replica count> <Namespace>. The data should be sorted by the increasing order of the deployment name.

Example: DEPLOYMENT CONTAINER_IMAGE READY_REPLICAS NAMESPACE deploy0 nginx:alpine 1 admin2406 Write the result to the file /opt/admin2406_data.

I didn't practice json path

kubectl -n admin2406 get deployment -o custom-columns=DEPLOYMENT:.metadata.name,CONTAINER_IMAGE:.spec.template.spec.containers[].image,READY_REPLICAS:.status.readyReplicas,NAMESPACE:.metadata.namespace --sort-by=.metadata.name > /opt/admin2406_data

Second Attempt

2 Wrong, the jsonpath and the deployment alpha-mysql.

• Regarding the jsonpath I don't know what to do tbh.

• For the deployment I must create a new PVC based on the information of the PV, what I was doing is trying to use a current PVC and change the deployment based on it which is not ideal.
