實(shí)例結(jié)構(gòu)

創(chuàng)建redis-master-controller.yaml

apiVersion: v1
kind: ReplicationController
metadata:
  name: redis-master
spec:
  replicas: 1
  selector:
    name: redis-master
  template:
    metadata:
      name: redis-master
      labels:
        name: redis-master
    spec:
      containers:
      - name: redis-master
        image: kubeguide/redis-master
        ports:
        - containerPort: 6379

發(fā)布到kubernetes集群,自動(dòng)創(chuàng)建pod

kubectl create -f redis-master-controller.yaml
kubectl get rc
kubectl get pods

創(chuàng)建redis-master-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: redis-master
  labels:
    name: redis-master
spec:
  ports:
  - port: 6379
    targetPort: 6379
  selector:
    name: redis-master

創(chuàng)建service

kubectl create -f redis-master-service.yaml
kubectl get services

創(chuàng)建redis-slave-controller.yaml

apiVersion: v1
kind: ReplicationController
metadata:
  name: redis-slave
spec:
  replicas: 2
  selector:
    name: redis-slave
  template:
    metadata:
      name: redis-slave
      labels:
        name: redis-slave
    spec:
      containers:
      - name: redis-slave
        image: kubeguide/guestbook-redis-slave
        env:
        - name: GET_HOSTS_FROM
          value: env
        ports:
        - containerPort: 6379

創(chuàng)建

kubectl create -f redis-slave-controller.yaml
kubectl get rc
kubectl get pods

創(chuàng)建redis-slave-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: redis-slave
  labels:
    name: redis-slave
spec:
  ports:
  - port: 6379
  selector:
    name: redis-slave

創(chuàng)建

kubectl create -f redis-slave-service.yaml
kubectl get services

創(chuàng)建frontend-controller.yaml

apiVersion: v1
kind: ReplicationController
metadata:
  name: frontend
  labels:
    name: frontend
spec:
  replicas: 3
  selector:
    name: frontend
  template:
    metadata:
      labels:
        name: frontend
    spec:
      containers:
      - name: frontend
        image: kubeguide/guestbook-php-frontend
        env:
        - name: GET_HOSTS_FROM
          value: env
        ports:
        - containerPort: 80

創(chuàng)建

kubectl create -f frontend-controller.yaml
kubectl get rc
kubectl get pods

創(chuàng)建frontend-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: frontend
  labels:
    name: frontend
spec:
  type: NodePort
  ports:
  - port: 80
    nodePort: 30001
  selector:
    name: frontend

創(chuàng)建

kubectl create -f frontend-service.yaml
kubectl get services

訪問(wèn)
http://your-host:30001/

全部啟動(dòng)后的kubernetes-ui

刪除

kubectl delete -f frontend-controller.yaml
replicationcontroller "frontend" deleted
kubectl delete -f redis-master-controller.yaml
replicationcontroller "redis-master" deleted
kubectl delete -f redis-slave-controller.yaml
replicationcontroller "redis-slave" deleted
kubectl delete -f redis-slave-service.yaml
service "redis-slave" deleted
kubectl delete -f redis-master-service.yaml
service "redis-master" deleted
kubectl delete -f frontend-service.yaml
