1.helm部署grafana

部署很簡單,見下

[root@k8s-node1 prometheus-grafana]# helm install stable/grafana --generate-name
NAME: grafana-1577432108
LAST DEPLOYED: Fri Dec 27 15:35:11 2019
NAMESPACE: default
STATUS: deployed
REVISION: 1
NOTES:
1. Get your 'admin' user password by running:

   kubectl get secret --namespace default grafana-1577432108 -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-1577432108.default.svc.cluster.local

   Get the Grafana URL to visit by running these commands in the same shell:

     export POD_NAME=$(kubectl get pods --namespace default -l "app=grafana,release=grafana-1577432108" -o jsonpath="{.items[0].metadata.name}")
     kubectl --namespace default port-forward $POD_NAME 3000

3. Login with the password from step 1 and the username: admin

注意這條:

1. Get your 'admin' user password by running:

   kubectl get secret --namespace default grafana-1577432108 -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

服務起來了

[root@k8s-node1 ~]# kubectl get svc,pod |grep grafana

service/grafana-1577432108                         ClusterIP   10.254.172.86            80/TCP          132m
pod/grafana-1577432108-65b987fdc6-dlhpb                         1/1     Running   1          132m

2.配置web訪問

配置Ingress文件,讀取執(zhí)行,然后做host解析即可通過grafana-server訪問web.

[root@k8s-node1 prometheus-grafana]# cat grafana-server-ingress.yaml 
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: grafana-server
  namespace: default
spec:
  rules:
  - host: grafana-server
    http:
      paths:
      - path: /
        backend:
          serviceName: grafana-1577432108
          servicePort: 80

http url是prometheus service的地址

[root@k8s-node1 prometheus-grafana]# kubectl get svc |grep server
prometheus-1577263826-server               ClusterIP   10.254.132.104           80/TCP          47h
