wordpress + mysql

image都是官方的，使用NodePort方式暴露端口来供外部访问

创建namespace

kubectl create namespace wordpress

编写mysql的yaml文件

vim wordpress-db.yaml

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: mysql-deploy
  namespace: wordpress
  labels:
    app: mysql
spec:
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
      - name: mysql
        image: mysql:5.6  
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 3306
          name: dbport
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: rootPassW0rd
        - name: MYSQL_DATABASE
          value: wordpress
        - name: MYSQL_USER
          value: wordpress
        - name: MYSQL_PASSWORD
          value: wordpress
        volumeMounts:
        - name: db
          mountPath: /var/lib/mysql
      volumes:
      - name: db
        hostPath:
          path: /var/lib/mysql

spec:
  selector:
    app: mysql
  ports:
  - name: mysqlport
    protocol: TCP
    port: 3306
    targetPort: dbport

部署yaml文件

kubectl apply -f wordpress-db.yaml

查看wordpress命名空间下创建的pod资源

kubectl get pods -n wordpress -o wide

编写wordpress的yaml文件

vim wordpress.yaml

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: wordpress-deploy
  namespace: wordpress
  labels:
    app: wordpress
spec:
  template:
    metadata:

    spec:
      containers:
      - name: wordpress
        image: wordpress
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80
          name: wdport
        # 这里修改成mysql的pod的访问地址，账号和密码
        env:
        - name: WORDPRESS_DB_HOST
          # 这里是mysql的pod外面的service的IP地址，不是mysql的pod的IP地址
          value: 10.105.38.153:3306 
          # 这里也可以使用service的名称
          # value: mysql:3306
        - name: WORDPRESS_DB_USER
          value: wordpress
        - name: WORDPRESS_DB_PASSWORD
          value: wordpress

apiVersion: v1
kind: Service
metadata:
  name: wordpress
  namespace: wordpress
spec:
  # NodePort类型的service会在node上都暴露端口给外部访问
  type: NodePort
  selector:
    app: wordpress
  ports:
  - name: wordpressport
    protocol: TCP
    port: 80
    targetPort: wdport

查看wordpress这个namespace下面的service的详情信息

kubectl get svc -n wordpress -o wide

查看wordpress这个namespace下面的pod的详情信息

kubectl get pods -n wordpress -o wide

访问集群中部署了wordpress这个pod的node的外网访问IP和对外暴露的端口，即可访问wordpress

访问地址：http://121.40.226.50:31805/
如果是阿里云ECS需要开通端口的访问IP白名单

Spring Boot项目

image是自己的，使用Ingress来供外部访问

创建namespace

kubectl create namespace springboot-demo

使用maven命令打包springboot项目

mvn clean package -Dmaven.test.skip=true

将打包生成的jar文件上传到服务器上
创建Dockerfile

vim Dockerfile

FROM openjdk:8-jre-alpine
COPY springboot-demo-0.0.1-SNAPSHOT.jar /springboot-demo.jar
ENTRYPOINT ["java","-jar","/springboot-demo.jar"]

构建Dockerfile，创建image

docker build -t springboot-demo-image .

把image上传到阿里云镜像仓库

docker tag springboot-demo-image registry-vpc.cn-hangzhou.aliyuncs.com/djflying/springboot-demo-image:v1.0

docker login --username=djflying1988@163.com registry-vpc.cn-hangzhou.aliyuncs.com

docker push registry-vpc.cn-hangzhou.aliyuncs.com/djflying/springboot-demo-image:v1.0

创建springboot的yaml文件

vim springboot-demo.yaml

# 以Deployment部署Pod
apiVersion: apps/v1
kind: Deployment
metadata: 
  name: springboot-demo
  namespace: springboot-demo
spec: 
  selector:

        ports: 
        - containerPort: 8080

  - port: 80
    protocol: TCP
    targetPort: 8080
  selector: 
    app: springboot-demo
---
# 创建Ingress，定义访问规则，一定要记得提前创建好nginx ingress controller
apiVersion: extensions/v1beta1
kind: Ingress
metadata:

  rules: 
  - host: springboot-demo.djflying.top
    http: 
      paths: 
      - path: /
        backend: 
          serviceName: springboot-demo
          servicePort: 80

部署yaml文件

kubectl apply -f springboot-demo.yaml

查看springboot-demo这个namespace下面的pod的详情信息

kubectl get pods -n springboot-demo -o wide
