修改grafana-pvc.yaml文件中的信息，然后应用YAML文件

bash 复制代码

cat > /opt/k8s/grafana/grafana-pvc.yaml <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: grafana-data-pvc
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: "nfs-storage"
  resources:
    requests:
      storage: 5Gi
EOF

bash 复制代码

kubectl apply -f grafana-pvc.yaml 
kubectl get pvc

部署ConfigMap

上传文件grafana.ini 到/opt/k8s/grafana/file/下

bash 复制代码

kubectl create configmap grafana-config \
  --from-file=grafana.yml=/opt/k8s/grafana/file/grafana.ini

如需修改可使用kubectl edit 或者以下方式

删除现有的ConfigMap
kubectl delete configmap grafana-config
使用新的文件重新创建ConfigMap
kubectl create configmap grafana-config

--from-file=grafana.yml=/opt/k8s/grafana/file/grafana.ini

部署Deployment

修改grafana-Deployment.yaml文件中的信息，然后应用YAML文件

bash 复制代码

cat > /opt/k8s/grafana/grafana-Deployment.yaml <<EOF
apiVersion: apps/v1
kind: Deployment

  name: grafana
spec:
  replicas: 1
  selector:
