Installing Camel K on Google Kubernetes Engine (GKE)

This guide assumes you’ve already created a Kubernetes Engine cluster on https://console.cloud.google.com.

Make sure you’ve selected a version of Kubernetes greater than 1.11 when creating the cluster. You can create it in any region.

In the list of clusters for the current project, GKE provides a connection string that you need to execute on a shell to configure the kubectl command.

the connection string contains a --project flag that indicates your project ID. You should keep that information for the last step.

After executing the connection string, if everything is installed correctly, you should be able to execute:

kubectl get pod

When the cluster is first installed, you should find that "no pods are present" in the cluster. You can proceed with the installation then.

Before installing Camel K on a fresh GKE cluster, you need to perform some extra steps to give to your account the required cluster-admin permissions. This means executing the following command (replacing "your-address@gmail.com" with your account email address):

kubectl create clusterrolebinding user-cluster-admin-binding --clusterrole=cluster-admin --user=your-address@gmail.com

The command above is needed to make sure your user is able to delegate some permissions to Camel K service accounts.

The last thing to do is to configure gcr.io as registry to host your integration image.
