While trying to follow https://docs.gitlab.com/ee/ci/autodeploy/quick_start_guide.html, I found a number of issues with the current documentation and Auto Deploy script: * GKE no longer has a "Secrets" tab in the Google Cloud UI: https://docs.gitlab.com/ee/ci/autodeploy/quick_start_guide.html#copy-credentials-to-gitlab-com-project * Due to missing line breaks, you can't copy and paste the CA certificate in GitLab's UI and have it work:  I ended up running `gcloud get credentials`, looking in my `.kube/config`, pulling out the base64-encoded `certificate-authority-data`, and then using the decoded format that way. * The service token isn't available in the Google Cloud UI. You can only get this via `kubectl describe secrets` now. We need to add documentation for that. * What is the service token used for? I see no explanation why it's necessary or how to verify that it's correct. * There's no way to test the Kubernetes integration to make sure the settings are correct. * I had to precreate a Kubernetes namespace: ``` $ kubectl create -f nginx-deployment.yaml || kubectl replace -f nginx-deployment.yaml Error from server (NotFound): error when creating "nginx-deployment.yaml": namespaces "kube-test-147" not found Error from server (NotFound): error when replacing "nginx-deployment.yaml": namespaces "kube-test-147" not found ``` /cc: @markpundsack, @ayufan, @bikebilly
