拉取redis哨兵chart

helm pull bitnami/redis --version 28.0.5

部署redis哨兵

helm install redis redis -f redis/values_custom.yaml

创建nodeport svc共外部访问,文件名redis-np.yaml

apiVersion: v1
kind: Service
metadata:
  name: redis-np
spec:
  type: NodePort
  selector:
    app.kubernetes.io/instance: redis
    app.kubernetes.io/name: redis
    app.kubernetes.io/component: node
  ports:
    - name: redis
      port: 6379
      targetPort: 6379
      nodePort: 30000

部署nodeport svc

kubectl create -f redis-np.yaml
