When following the instructions to use the "kubernetes-university-live" code sample in Scylla U, a dependency is not listed, which causes a failure.

Steps to reproduce

  1. Install gcloud via the Google Cloud SDK.

  2. Initialize gcloud:

gcloud init
  1. Login via gcloud:
gcloud auth login

  1. Install kubectl.

  2. Install helm.

  3. Clone the repo:

git clone https://github.com/scylladb/scylla-code-samples.git
  1. Change directory:
cd scylla-code-samples/kubernetes-university-live
  1. Set the account and project to environment variables:
export GCP_USER=$(gcloud config list account --format "value(core.account)")   
export GCP_PROJECT=$(gcloud config list project --format "value(core.project)")
  1. Run the gke.sh script:
./gke.sh --gcp-user "$GCP_USER" -p "$GCP_PROJECT" -c "university-live-demo"

Actual results

A failure occurs due to a missing dependency:

It looks like you are trying to use a client-go credential plugin that is not installed.

To learn more about this feature, consult the documentation available at:
      https://kubernetes.io/docs/reference/access-authn-authz/authentication/#client-go-credential-plugins

Install gke-gcloud-auth-plugin for use with kubectl by following https://cloud.google.com/blog/products/containers-kubernetes/kubectl-auth-changes-in-gke

Expected results

The missing dependency must be installed prior to running gke.sh:

sudo apt install google-cloud-cli-gke-gcloud-auth-plugin

While updating this section, it would be good to also deal with this: WARNING: The --enable-stackdriver-kubernetes flag is deprecated and will be removed in an upcoming release. Please use --logging and --monitoring instead. For more information, please read: https://cloud.google.com/stackdriver/docs/solutions/gke/installing.

@GeoffMontee can you test with the alternate - --logging and --monitoring, removing the --enable-stackdriver-kubernetes flag?

These deprecations are things that will break scylla u when they become removed.

Thanks, @pdbossman. I will test this change to avoid the deprecation warning:
