定义一个mysql的RC文件：mysql-rc.yaml

apiVersion: v1
kind: ReplicationController
metadata:
  name: mysql
spec:
  replicas: 1
  selector:
    app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
      - name: mysql
        image: mysql
        ports:
        - containerPort: 3306
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: "123456"

发布到k8s集群中

# kubectl create -f mysql-rc.yaml

    1
    2

报错：

The connection to the server localhost:8080 was refused - did you specify the right host or port?

没有启动k8s集群或启动顺序不对，重新按一下顺序启动所有服务：

# systemctl start etcd
# systemctl start docker
# systemctl start kube-apiserver
# systemctl start kube-controller-manager
# systemctl start kube-scheduler
# systemctl start kubelet
# systemctl start kube-proxy

然后再发布mysql-rc.yaml就不报错了
