一.部署sentinel

1.編寫資源清單

[root@master241 07-sentinel]# cat 01-deploy-sentinel.yaml 
apiVersion:  apps/v1
kind: Deployment
metadata:
  name: deploy-sentinel
spec:
  replicas: 1
  selector:
    matchLabels:
      apps: sentinel
  template:
    metadata:
      labels:
        apps: sentinel
    spec:
      containers:
      - name: sentinel
        image: docker.io/herodotus/sentinel-dashboard:v1.8.8
        ports:
        - containerPort: 8858
          name: web
[root@master241 07-sentinel]# 
[root@master241 07-sentinel]# cat 02-svc-sentinel.yaml 
apiVersion: v1
kind: Service
metadata:
  name: svc-sentinel
spec:
  ports:
  - port: 8858
  selector:
    apps: sentinel
  type: LoadBalancer
[root@master241 07-sentinel]# 

2.部署服務(wù)

[root@master241 07-sentinel]# ll

[root@master241 07-sentinel]# 
[root@master241 07-sentinel]# kubectl apply -f .
