其中

env.DOCKER_REGISTRY_NAME = hub.xx.com:10443
env.DOCKER_REGISTRY= https://hub.xx.com:10443
env.DOCKER_CERT_PATH = E:\Doc\cert\hub.xx.com
env.DOCKER_HOST =  tcp://172.168.1.1:2375

注意：

最终的镜像一定要是~/~/~:~ 格式，如

${docker.repostory}/${docker.registry.name}/${project.artifactId}:${project.version}

mvn的setting配置

开放docker的2375端口方法

vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
#重新加载docker配置
systemctl daemon-reload // 1，加载docker守护线程
systemctl restart docker // 2，重启docker

如果需要有docker服务器推送到私有中央仓库且为https协议，需要在/etc/docker/certs.d目录下配置证书，证书放置文件夹为私有仓库的域名如hub.123.com:10443
