Solution - Troubleshooting Permission Errors When Deploying Into A GKE Cluster

Issue

When attempting to deploy Ondat onto a new GKE cluster with the Ondat kubectl plugin, you experience a permission error message that causes the installation to fail.

# installing Ondat using the Ondat kubectl plugin
kubectl storageos install \
  --include-etcd \
  --admin-username "storageos" \
  --admin-password "storageos"

# log output
namespace/storageos-etcd created
Warning: resource namespaces/storageos is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by  apply.  apply should only be used on resources created declaratively by either  create --save-config or  apply. The missing annotation will be patched automatically.

Root Cause

  • The permission error messages that are returned is due to not having the correct privileges to be able to install Ondat in a GKE cluster.

Resolution

  • To resolve this issue, ensure that your user account has cluster administrator privileges first so that you can install Ondat successfully.
kubectl create clusterrolebinding cluster-admin-binding \
  --clusterrole=cluster-admin \
  --user=$(gcloud config get-value account)
