在dockfile基础上先把做好的镜像推到本地仓库

docker tag nginx:v1 10.0.0.11:5000/nginx:v1
docker push 10.0.0.11:5000/nginx:v1

创建rc

vim /k8s/rc/rc_kod.yaml

kind: ReplicationController
metadata:
  name: nginx
spec:
  replicas: 5
  selector:
    app: myweb
  template:
    metadata:
      labels:
        app: myweb
    spec:
      containers:
      - name: myweb
        image: 10.0.0.11:5000/nginx:v1
        ports:
        - containerPort: 80

kubectl create -f  /k8s/rc/rc_kod.yaml

创建service(用于负载)

vim /k8s/svc/svc_kod.yaml
apiVersion: v1
kind: Service
metadata:
  name: myweb
spec:
  type: NodePort
  ports:
    - port: 80
      nodePort: 3000
      targetPort: 80
  selector:
    app: myweb

kubectl create -f  /k8s/rc/svc_kod.yaml

注意他们APP必须保持一致
