本文主要介绍搭建一个简单spring boot项目并发布镜像到远程docker服务器上。

环境：

spring boot 2.1.0.RELEASE

maven

docker 19.03

IDEA

环境搭建

新建spring boot项目，增加测试方法

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @ResponseBody
    @RequestMapping(value = "/")
    String home() {
        return "Hello Docker World";
    }
}

    </build>

</project>

dockerHost配置为远程要访问的docker

docker开启远程访问

我的服务器环境是ubuntu18.04、docker19.03.5

sudo vim /lib/systemd/system/docker.service

修改ExecStart这行，新增" -H tcp://0.0.0.0:2375  "

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

重启docker服务
sudo systemctl daemon-reload
sudo systemctl restart docker

2. 远程发布镜像

在idea maven plugin中使用docker build

3. 启动容器

docker images  查看发布的镜像

docker run -d -p 8080:8080 你的镜像id或镜像名称

暴露8080端口

4. 验证

浏览器输入 http://192.168.50.185:8080/ 显示Hello Docker World
