一.部署sentinel

1.编写资源清单

[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.部署服务

[root@master241 07-sentinel]# ll
total 16
drwxr-xr-x 2 root root 4096 Jul 14 17:53 ./
drwxr-xr-x 9 root root 4096 Jul 14 16:38 ../
-rw-r--r-- 1 root root  382 Jul 14 17:49 01-deploy-sentinel.yaml
-rw-r--r-- 1 root root  142 Jul 14 17:53 02-svc-sentinel.yaml
[root@master241 07-sentinel]# 
[root@master241 07-sentinel]# kubectl apply -f .
deployment.apps/deploy-sentinel created
service/svc-sentinel created
[root@master241 07-sentinel]# 
[root@master241 07-sentinel]# kubectl get pods -l apps=sentinel -o wide

[root@master241 07-sentinel]# 
[root@master241 07-sentinel]# kubectl get svc svc-sentinel

[root@master241 07-sentinel]#
