1. Watch Jenkins instance being created:
$ kubectl --namespace {{ .Release.Namespace }} get pods -w

2. Get Jenkins credentials:
$ kubectl --namespace {{ .Release.Namespace }} get secret jenkins-operator-credentials-{{ .Values.jenkins.name }} -o 'jsonpath={.data.user}' | base64 -d
$ kubectl --namespace {{ .Release.Namespace }} get secret jenkins-operator-credentials-{{ .Values.jenkins.name }} -o 'jsonpath={.data.password}' | base64 -d

3. Connect to Jenkins (actual Kubernetes cluster):
$ kubectl --namespace {{ .Release.Namespace }} port-forward jenkins-{{ .Values.jenkins.name }} 8080:8080

Now open the browser and enter http://localhost:8080
