k8s部署grafana

修改grafana-pvc.yaml文件中的信息，然后应用YAML文件

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

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

部署ConfigMap

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

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
