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

报错：

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
