idea 搭建 docker
服务器端 idea 开启远程
pom.xml 修改如下
在 src 目录下 创建 docker 目录
编写 Dockerfile

FROM java:8
MAINTAINER dj dj@qq.com
COPY *.jar /app.jar
EXPOSE 8081
ENTRYPOINT ["java","-jar","app.jar"]


使用插件打包即可发布到测试环境

docker 加速方案

可信镜像源 https://hub.atomgit.com/

https://hub.gog.email/

在名称前加入 地址 hub.gog.email/
 docker pull hub.gog.email/apache/skywalking-oap-server:9.4.0 
2

 vi /etc/docker/daemon.json 
 添加一下内容
 {"registry-mirrors": ["https://hub.gog.email"]} 
 systemctl daemon-reload &&  systemctl restart docker
