1. Get your 'admin' user password by running:
|
|
|
|
kubectl get secret --namespace grafana grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
|
|
|
|
|
|
2. The Grafana server can be accessed via port 80 on the following DNS name from within your cluster:
|
|
|
|
grafana.grafana.svc.cluster.local
|
|
|
|
Get the Grafana URL to visit by running these commands in the same shell:
|
|
export POD_NAME=$(kubectl get pods --namespace grafana -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=grafana" -o jsonpath="{.items[0].metadata.name}")
|
|
kubectl --namespace grafana port-forward $POD_NAME 3000
|
|
|
|
3. Login with the password from step 1 and the username: admin
