开放2375端口
1# 开启防火墙端口 2firewall-cmd --zone=public --add-port=2375/tcp --permanent 3systemctl restart firewalld
配置私有仓库
配置daemon.json文件
1[root@localhost admin]# vim /etc/docker/daemon.json 2 3{ 4 "insecure-registries":["192.168.192.128:443"] 5}
1# 重启服务 2systemctl daemon-reload 3systemctl restart docker
然后下载registry镜像
1[root@localhost admin]# docker pull registry 2[root@localhost admin]# mkdir /usr/docker_registry_data 3[root@localhost admin]# docker run -d -p 443:5000 -v /usr/docker_registry_data:/var/lib/registry registry 4 5# 开启防火墙端口 6firewall-cmd --zone=public --add-port=443/tcp --permanent 7systemctl restart firewalld

打包（注意，要保证服务器的Registry容器开启）
1SET DOCKER_HOST=tcp://192.168.192.128:2375 2mvn clean package -Dmaven.test.skip=true docker:build -DpushImageTag
成功
现在回来看镜像
启动（后台启动加上-d）
访问
另一种方式：Dockerfile
在src/main下新建一个docker目录
Dockerfile内容
1# 基础镜像 2FROM java:8 3# 打包jar去向 4ADD /hello-0.0.1-SNAPSHOT.jar /app.jar 5# 暴露端口 6EXPOSE 8081 7# 启动命令 8ENTRYPOINT ["java", "-jar", "/app.jar"]
pom文件修改如下：

打包推送
