修改掛載目錄權限
如果就這樣部署，會發(fā)生錯誤：
? ~ kubectl logs -f grafana-xxx -n grafana-system
GF_PATHS_DATA='/var/lib/grafana' is not writable.
You may have issues with file permissions, more information here: http://docs.grafana.org/installation/docker/#migration-from-a-previous-version-of-the-docker-container-to-5-1-or-later
mkdir: cannot create directory '/var/lib/grafana/plugins': Permission denied
可以看出是由于沒有目錄權限引起的，我們可以通過修改目錄權限來解決這個問題，我們可以了利用一個 Job 來幫我們解決這個問題：
apiVersion: batch/v1

name: grafana-chown

Service
創(chuàng)建 grafana 訪問所需的 service, 可以根據(jù)自己需求自行修改骨杂，我這里因為我的集群部署了 Ingress 控制器，所以使用 ClusterIP。
apiVersion: v1

Ingress
創(chuàng)建 grafana 訪問所需的 ingress。
apiVersion: networking.k8s.io/v1
kind: Ingress
