1、部署redis-master Deployment Step1 编辑redis-master-deployment.yaml # application/guestbook/redis-master-deployment.yaml apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2 kind: Deployment metadata: name: redis-master labels: app: redis spec: selector: matchLabels: app: redis role: master tier: backend replicas: 1 template: metadata: labels: app: redis role: master tier: backend spec: containers: - name: master image: redis # or just image: redis resources: requests: cpu: 100m memory: 100Mi ports: - containerPort: 6379 Step2 执行命令 # 创建Deployment kubectl create -f redis-master-deployment.yaml # 查看pods kubectl get pods 2、部署redis-master Service Step1 编辑redis-master-service.yaml # application/guestbook/redis-master-service.yaml apiVersion: v1 kind: Service metadata: name: redis-master labels: app: redis role: master tier: backend spec: ports: - port: 6379 targetPort: 6379 selector: app: redis role: master tier: backend Step2 执行命令 # 创建DService kubectl create -f redis-master-service.yaml # 查看service kubectl get services 3、部署redis-slave Deployment Step1 编辑redis-slave-deployment.yaml # application/guestbook/redis-slave-deployment.yaml apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2 kind: Deployment metadata: name: redis-slave labels: app: redis spec: selector: matchLabels: app: redis role: slave tier: backend replicas: 2 template: metadata: labels: app: redis role: slave tier: backend spec: containers: - name: slave image: gcr.io/google_samples/gb-redisslave:v3 resources: requests: cpu: 100m memory: 100Mi env: - name: GET_HOSTS_FROM value: dns # Using `GET_HOSTS_FROM=dns` requires your cluster to # provide a dns service. As of Kubernetes 1.3, DNS is a built-in # service launched automatically. However, if the cluster you are using # does not have a built-in DNS service, you can instead # access an environment variable to find the master # service's host. To do so, comment out the 'value: dns' line above, and # uncomment the line below: # value: env ports: - containerPort: 6379 Step2 执行命令 kubectl create -f redis-slave-deployment.yaml kubectl get pods 4、部署redis slave Service Step1 编辑redis-slave-service.yaml # application/guestbook/redis-slave-service.yaml apiVersion: v1 kind: Service metadata: name: redis-slave labels: app: redis role: slave tier: backend spec: ports: - port: 6379 selector: app: redis role: slave tier: backend Step2 执行命令 kubectl create -f redis-slave-service.yaml kubectl get services 5、部署guestbook Deployment Step1 编辑frontend-deployment.yaml # application/guestbook/frontend-deployment.yaml apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2 kind: Deployment metadata: name: frontend labels: app: guestbook spec: selector: matchLabels: app: guestbook tier: frontend replicas: 3 template: metadata: labels: app: guestbook tier: frontend spec: containers: - name: php-redis image: gcr.io/google-samples/gb-frontend:v6 # 官网上使用的是v4版，在使用中出现ImageInspectErr，镜像出现问题，升级为v6 resources: requests: cpu: 100m memory: 100Mi env: - name: GET_HOSTS_FROM value: dns # Using `GET_HOSTS_FROM=dns` requires your cluster to # provide a dns service. As of Kubernetes 1.3, DNS is a built-in # service launched automatically. However, if the cluster you are using # does not have a built-in DNS service, you can instead # access an environment variable to find the master # service's host. To do so, comment out the 'value: dns' line above, and # uncomment the line below: # value: env ports: - containerPort: 80 Step2 执行命令 kubectl create -f frontend-deployment.yaml kubectl get pods 6、部署guestbook Service Step1 编辑frontend-service.yaml # application/guestbook/frontend-service.yaml apiVersion: v1 kind: Service metadata: name: frontend labels: app: guestbook tier: frontend spec: # comment or delete the following line if you want to use a LoadBalancer type: NodePort # if your cluster supports it, uncomment the following to automatically create # an external load-balanced IP for the frontend service. # type: LoadBalancer ports: - port: 80 selector: app: guestbook tier: frontend Step2 执行命令 kubectl create -f frontend-service.yaml kubectl get services 然后使用node的IP和端口，就可以访问服务了。
