kubernetes上部署应用实例

实例结构

创建redis-master-controller.yaml

apiVersion: v1 kind: ReplicationController metadata:name: redis-master spec:replicas: 1selector:name: redis-mastertemplate:metadata:name: redis-masterlabels:name: redis-masterspec:containers:- name: redis-masterimage: kubeguide/redis-masterports:- containerPort: 6379

发布到kubernetes集群,自动创建pod

kubectl create -f redis-master-controller.yaml kubectl get rc kubectl get pods

创建redis-master-service.yaml

apiVersion: v1 kind: Service metadata:name: redis-masterlabels:name: redis-master spec:ports:- port: 6379targetPort: 6379selector:name: redis-master

创建service

kubectl create -f redis-master-service.yaml kubectl get services

创建redis-slave-controller.yaml

apiVersion: v1 kind: ReplicationController metadata:name: redis-slave spec:replicas: 2selector:name: redis-slavetemplate:metadata:name: redis-slavelabels:name: redis-slavespec:containers:- name: redis-slaveimage: kubeguide/guestbook-redis-slaveenv:- name: GET_HOSTS_FROMvalue: envports:- containerPort: 6379
