Mac使用本地docker，在IDEA进行本地容器化部署、启动

1、idea安装docker插件：

2、Idea连接本地docker测试：

 

 如果连接失败，连接失败原因：基于mac的docker for mac本身不支持远程访问，需要依赖一款名叫 socat的网络工具提供的镜像来做远程访问。

安装socat执行以下步骤：

2.1、brew install socat  出现以下问题，执行2.2步骤；

2.2 brew更新步骤：

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc
source ~/.zshrc
brew update
brew install socat

2.3 启动socat：

socat -d TCP-LISTEN:2375,range=127.0.0.1/32,reuseaddr,fork UNIX:/var/run/docker.sock

后台启动：

nohup socat -d TCP-LISTEN:2375,range=127.0.0.1/32,reuseaddr,fork UNIX:/var/run/docker.sock &

最后返回idea进行docker连接就可以了；

连接成功可以看到docker中已经启动的容器和已经装载的镜像；

 

3、 新建一个springboot项目进行测试；

项目结构如下：

 3.1 新建Dockerfile文件：

FROM openjdk:8-jdk-alpine
ADD *.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

 3.2 pom.xml文件需要引入的依赖和插件：

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.3 新建application.properties文件：

server.port=8088

 3.4 新建DockerApplication文件：

package com.tealala;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class DockerApplication {
    public static void main(String[] args) {
        SpringApplication.run(DockerApplication.class, args);
    }
}

3.5新建DockerController文件：

package com.tealala;
 
import org.apache.juli.logging.Log;
import org.apache.juli.logging.LogFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
public class DockerController {
    static Log LOGGER = LogFactory.getLog(DockerController.class);
 
    @RequestMapping("/docker")
    public String index(){
        LOGGER.info("hello docker!");
        return "Hello Docker!";
    }
}

3.6 docker启动配置：
