- 创建redis-master Pod和服务
先定义RC来创建pod,然后定义与之关联的service。
为redis-master服务新建一个名为redis-master-controller.yaml的RC定义文件,内容为:
apiVersion: v1
kind: ReplicationController
metadata:
name: redis-master
labels:
name: redis-master
spec:
replicas: 1
selector:
name: redis-master
template:
metadata:
labels:
name: redis-master
spec:
containers:
- name: master
image: kubeguide/redis-master
ports:
- containerPort: 6379
新建好文件之后执行如下命令:
kubectl create -f redis-master-controller.yaml
删除：将create换为delete即可。
查看刚刚新建的redis-master：
kubectl get rc
检查pod信息:
kubectl get pods
下面新建与上面建的pod相关联的service,service对应的文件redis-master-service.yaml,内容如下:
apiVersion: v1
kind: Service
metadata:
name: redis-master
labels:
name: redis-master
spec:
ports:
- port: 6379
targetPort: 6379
selector:
name: redis-master
创建service：
kubectl create -f redis-master-service.yaml
查看新建的service:
kubectl get services
2. redis-slave Pod和服务
步骤和redis-master的一样。
新建文件redis-slave-controller.yaml，内容如下:
apiVersion: v1
kind: ReplicationController
metadata:
name: redis-slave
labels:
name: redis-slave
spec:
replicas: 2
selector:
name: redis-slave
template:
metadata:
labels:
name: redis-slave
spec:
containers:
- name: slave
image: kubeguide/guestbook-redis-slave
env:
- name: GET_HOSTS_FROM
value: env
ports:
- containerPort: 6379
运行kubectl create命令:
kubectl create -f redis-slave-controller.yaml
查看RC:
kubectl get rc
查看pod:
kubectl get pods
配置文件redis-slave-service.yaml内容如下:
apiVersion: v1
kind: Service
metadata:
name: redis-slave
labels:
name: redis-slave
spec:
ports:
- port: 6379
selector:
name: redis-slave
创建service：
kubectl create -f redis-slave-service.yaml
检查service：
kubectl get services;
