1.配置docker远程连接端口

 vi /usr/lib/systemd/system/docker.service

 找到 ExecStart，在最后面添加 -H tcp://0.0.0.0:2375

 

装好docker插件，配置好连接，启动就可以看到docker上的容器和镜像。

 

如果上面配置没有效，就这样配置

ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375 -H fd:// --containerd=/run/containerd/containerd.sock 

 

2.新建项目

新建一个SpringBoot项目

 pom配置：

Controller:

@RestController
public class DockerController {
    static Log log = LogFactory.getLog(DockerController.class);

    @RequestMapping("/")
    public String index() {
        log.info("Hello Docker!");
        return "Hello Docker!";
    }
}

 Dockerfile:

FROM registry.cn-hangzhou.aliyuncs.com/choerodon-tools/javabase:0.5.0
ADD *.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

3.新建配置

  

 启动docker

 启动项目：

ok 访问成功！
