k8s 部署 grafana

创建namespace

grafana-namespace.yaml

apiVersion: v1
kind: Namespace
metadata:
  name: ns-grafana

拉取镜像

swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/rancher/mirrored-grafana-grafana:10.3.3

grafana的Deployment

grafana-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: grafana
  namespace: ns-grafana
spec:
  replicas: 1
  selector:
    matchLabels:
      task: monitoring
      name: grafana
  template:
    metadata:
      labels:
        task: monitoring
        name: grafana
    spec:
      # hostNetwork: true
      containers:
      - name: grafana
        image: swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/rancher/mirrored-grafana-grafana:10.3.3
        ports:
        - containerPort: 3000
          protocol: TCP
 

如果使用Service模式部署可以注释hostNetwork: true；
