tar xvf etcd-v0.4.6-linux-amd64.tar.gz

创建pod
搭好了运行环境后，就可以提交pod了。首先编写pod描述文件，保存为redis.json：

{"id": "redis","desiredState": {"manifest": {"version": "v1beta1","id": "redis","containers": [{"name": "redis","image": "dockerfile/redis","imagePullPolicy": "PullIfNotPresent","ports": [{"containerPort": 6379,"hostPort": 6379}]}]}},"labels": {"name": "redis"}
}

然后，通过命令行工具kubecfg提交：

./kubecfg -c redis.json create /pods

提交完后，通过kubecfg查看pod状态：

# ./kubecfg list /pods
ID                  Image(s)            Host                Labels              Status
----------          ----------          ----------          ----------          ----------
redis               dockerfile/redis    127.0.0.1/          name=redis          Running

Status是Running表示pod已经在容器里运行起来了，可以用"docker ps"命令来查看容器信息:

# docker ps
CONTAINER ID        IMAGE                     COMMAND                CREATED             STATUS              PORTS                    NAMES
ae83d1e4b1ec        dockerfile/redis:latest   "redis-server /etc/r   19 seconds ago      Up 19 seconds                                k8s_redis.caa18858_redis.default.etcd_1414684622_1b43fe35

创建replicationController

{"id": "redisController","apiVersion": "v1beta1","kind": "ReplicationController","desiredState": {"replicas": 1,"replicaSelector": {"name": "redis"},"podTemplate": {"desiredState": {"manifest": {"version": "v1beta1","id": "redisController","containers": [{"name": "redis","image": "dockerfile/redis","imagePullPolicy": "PullIfNotPresent","ports": [{"containerPort": 6379,"hostPort": 6379}]}]}},"labels": {"name": "redis"}}},"labels": {"name": "redis"}}

然后，通过命令行工具kubecfg提交：

./kubecfg -c redisController.json create /replicationControllers 

提交完后，通过kubecfg查看replicationController状态：

# ./kubecfg list /replicationControllers
ID                  Image(s)            Selector            Replicas
----------          ----------          ----------          ----------
redisController     dockerfile/redis    name=redis          1

同时，1个pod也将被自动创建出来，即使我们故意删除该pod，replicationController也将保证创建1个新pod。
