Configure a Pod to Use a Projected Volume for Storage

    Note: serviceAccountToken is not a volume type.

    You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:

    To check the version, enter kubectl version.

    Here is the configuration file for the Pod:

    1. Create the Secrets:

      1. echo -n "admin" > ./username.txt
      2. echo -n "1f2d1e2e67df" > ./password.txt
      4. # Package these files into secrets:
      5. kubectl create secret generic user --from-file=./username.txt

    3. In another terminal, get a shell to the running container:

      1. kubectl exec -it test-projected-volume -- /bin/sh

    Delete the Pod and the Secrets:

    1. kubectl delete pod test-projected-volume
    2. kubectl delete secret user pass
