项目结构如图:

  1. Dockerfile 文件 构建镜像: 
    #基础镜像,如果本地仓库没有,会从远程仓库拉取 openjdk:8
    FROM openjdk:8
    #暴露端口
    EXPOSE 9301
    #容器中创建目录
    RUN mkdir -p /usr/local/java
    #编译后的jar包copy到容器中创建到目录内 ../../realize-gateway
    COPY realize-auth.jar /usr/local/java/realize-auth.jar
    #指定容器时区
    RUN rm -f /etc/localtime \
    && ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
    && echo "Asia/Shanghai" > /etc/timezone
    #指定容器启动时要执行的命令
    ENTRYPOINT ["java","-jar","-Dspring.profiles.active=server","/usr/local/java/realize-auth.jar"]
    

  2.  k8s realize-auth.yaml 文件:
    apiVersion: v1
    kind: Service
    metadata:
      name: $IMG_NAME
      namespace: rz-dt
      labels:
        app: $IMG_NAME
    spec:
      type: ClusterIP #NodePort
      ports:
      - name: tcp-9301-9301
        port: 9301
        protocol: TCP
        targetPort: 9301
        #nodePort: 31050 #service对外开放端口
      selector:
        app: $IMG_NAME
    ---
    apiVersion: apps/v1
    kind: Deployment #对象类型
    metadata:
      name: $IMG_NAME #名称
      namespace: rz-dt
      labels:
        app: $IMG_NAME #标注
    spec:
      replicas: 1 #运行容器的副本数,修改这里可以快速修改分布式节点数量
      selector:
        matchLabels:
          app: $IMG_NAME
      template:
        metadata:
          labels:
            app: $IMG_NAME
        spec:
          containers: #docker容器的配置
            - name: $IMG_NAME
              image: rz-dt-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com/rz-dt/$IMG_NAME:$IMG_TAG # pull镜像的地址 ip:prot/dir/images:tag
              imagePullPolicy: Always #pull镜像时机,
              ports:
                - containerPort: 9301 #容器对外开放端口,需与springboot配置文件一致
              volumeMounts:
                - name: time-config
                  mountPath: /etc/localtime
                  readOnly: true
                - name: volume-logs
                  mountPath: /logs
                  subPath: logs
              resources:
                limits:
                  cpu: 500m
                  memory: 1Gi
                requests:
                  cpu: 10m
                  memory: 50Mi
          #从私有仓库拉取镜像凭证
          imagePullSecrets:
            - name: rz-dt-miyue-vpc
          volumes:
            - name: time-config
              hostPath:
                path: /usr/share/zoneinfo/Asia/Shanghai
            - name: volume-logs
              persistentVolumeClaim:
                claimName: rz-dt-nas-volume-claim
    

  3. centos配置kubectl客户端连接k8s集群,执行,sh test.sh测试环境发布k8s,sh real.sh生产环境
    echo "开始制作镜像..."
    image_name=realize-auth
    image_tag=`date +%Y-%m-%d-%H-%M-%S` #_%H%M
    echo "当前时间版本号:$image_tag"
    docker build -t ${image_name}:${image_tag} .
    echo "制作镜像成功!"
    
    echo "登录"
    sudo docker login --username=aliyun03985131512 rz-dt-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com --password=1234R
    
    echo "镜像最新版本提交"
    docker tag ${image_name}:${image_tag} rz-dt-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com/rz-dt/${image_name}:${image_tag}
    docker push rz-dt-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com/rz-dt/${image_name}:${image_tag}
    
    echo "k8s一键部署"
    export IMG_TAG=${image_tag}
    export IMG_NAME=${image_name}
    envsubst < ${image_name}.yaml | kubectl --kubeconfig ~/.kube-rz/config apply -f -
