用自己电脑做网站服务器电商运营培训班多少钱

1. Dockerfile文件编写

   #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. kubectl 定义资源文件

   apiVersion: v1
   kind: Service
   metadata:name: $IMG_NAMEnamespace: rzlabels:app: $IMG_NAME
   spec:type: ClusterIPports:- name: tcp-9301-9301port: 9301protocol: TCPtargetPort: 9301selector:app: $IMG_NAME
   ---
   apiVersion: apps/v1
   kind: Deployment #对象类型
   metadata:name: $IMG_NAME #名称namespace: rzlabels: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_NAMEtemplate:metadata:labels:app: $IMG_NAMEspec:containers: #docker容器的配置- name: $IMG_NAME
   #          env:
   #            - name: aliyun_logs_catalina
   #              value: stdoutimage: rz-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com/rz-real/$IMG_NAME:$IMG_TAG # pull镜像的地址 ip:prot/dir/images:tagimagePullPolicy: 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-configmountPath: /etc/localtimereadOnly: true- name: volume-logsmountPath: /logssubPath: logsresources:limits:cpu: 500mmemory: 1Girequests:cpu: 10mmemory: 50Mi#从私有仓库拉取镜像凭证imagePullSecrets:- name: miyue-vpcvolumes:- name: time-confighostPath:path: /usr/share/zoneinfo/Asia/Shanghai- name: volume-logspersistentVolumeClaim:claimName: nas-volume-claim-real
   

3. 一键shell脚本部署pod

   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=aliyun03 rz-dt-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com --password=1234echo "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-real/${image_name}:${image_tag}
   docker push rz-dt-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com/rz-dt-real/${image_name}:${image_tag}echo "k8s一键部署"
   export IMG_TAG=${image_tag}
   export IMG_NAME=${image_name}
   envsubst < ${image_name}'-real'.yaml | kubectl --kubeconfig ~/.kube-rz-real/config apply -f -
