Installing in GKE Cluster
If you are installing KubeDB on a GKE cluster, you will need cluster admin permissions to install KubeDB operator. Run the following command to grant admin permision to the cluster.
$ kubectl create clusterrolebinding "cluster-admin-$(whoami)" \
--clusterrole=cluster-admin \
--user="$(gcloud config get-value core/account)"
In addition, if your GKE cluster is a private cluster, you will need to either add an additional firewall rule that allows master nodes access port 8443/tcp on worker nodes, or change the existing rule that allows access to ports 443/tcp and 10250/tcp to also allow access to port 8443/tcp. The procedure to add or modify firewall rules is described in the official GKE documentation for private clusters mentioned before.
Detect KubeDB version
To detect KubeDB version, exec into the operator pod and run kubedb version command.
$ POD_NAMESPACE=kube-system
$ POD_NAME=$(kubectl get pods -n $POD_NAMESPACE -l app.kubernetes.io/name=kubedb -o jsonpath={.items[0].metadata.name})
$ kubectl exec $POD_NAME -c operator -n $POD_NAMESPACE -- /kubedb version
