Kubernetes - Jenkins integration

Question

I\'ve bootstrapped with kubeadm Kubernetes 1.9 RBAC cluster and I\'ve started inside a POD Jenkins based on jenkins/jenkins:lts. I would like to try out https://github.com/j

The Kubernetes plugin for Jenkins reads this file /var/run/secrets/kubernetes.io/serviceaccount/token. Please see if your Jenkins pod has this. The service account should have permissions targeting pods in the appropriate namespace.

In fact, we are using Jenkins running outside kubernetes 1.9. We simply picked the default service account token (from default namespace), and put it in that file on the Jenkins master. Restarted ... and the kubernetes token credential type was visible.

We do have a role and rolebinding though:

kubectl create role jenkins --verb=get,list,watch,create,patch,delete --resource=pods
kubectl create rolebinding jenkins --role=jenkins --serviceaccount=default:default

In our case, Jenkins is configured to spin up slave pods in the default namespace. So this combination works.
