Question
Unable to deploy to Digital Ocean Kubernetes using GitLab CI

Asked by Remco Haszing
I’m moving my review apps from Google Kubernetes to Digital Ocean Kubernetes.
I have succesfully linked the Kubernetes clusted to GitLab. I have installed Helm Tiller, Ingress, Cert-Manager, and Prometheus using the GitLab integration. I have upgraded Tiller to the latest version manually, as did I on the previous Google cluster.
The cluster is RBAC-enabled,GitLab-managed, configured to use the default namespace, and tied to the * wildcard environment scope.
Now my deployments are failing. job output
$ helm upgrade "$CI_ENVIRONMENT_SLUG" config/charts/appsemble-docs --atomic --install --set "git.commit.sha=$CI_COMMIT_SHA" --set "image.tag=$CI_COMMIT_REF_NAME"
Error: pods is forbidden: User "system:serviceaccount:default:default-service-account" cannot list resource "pods" in API group "" in the namespace "gitlab-managed-apps"
Manual deployments on my own laptop work fine.
What could be causing this issue?

Hi there,
This looks like an RBAC permissions issue. The error you’re seeing is saying the service-account “default-service-account” in namespace “default” doesnt have access to pods in the ‘gitlab-managed-apps’ namespace.
You can fix this by either creating a role that allows this access then binding the sa to that role witha rolebinding:
See below for examples to achieve something similar:
This will create a role pod-reader that can get, list, and watch pods
kubectl create role pod-reader --verb=get,list,watch --resource=pods -n <namespace to read pods>
Then we will create the rolebinding to associate a serviceaccount to this role that can view pods.
kubectl create rolebinding sa-read-pods --role=pod-reader --user=system:serviceaccount:default:default-service-account -n rbac
Let me know if you have any further questions.
