idea整合docker

1.开启docker远程访问

[root@izwz9eftauv7x69f5jvi96z docker]# vim /usr/lib/systemd/system/docker.service
#修改ExecStart这行
ExecStart=/usr/bin/dockerd  -H tcp://0.0.0.0:2375  -H unix:///var/run/docker.sock
#重新加载配置文件
[root@izwz9eftauv7x69f5jvi96z docker]# systemctl daemon-reload    
#重启服务
[root@izwz9eftauv7x69f5jvi96z docker]# systemctl restart docker.service 
#查看端口是否开启
[root@izwz9eftauv7x69f5jvi96z docker]# netstat -nlpt
#直接curl看是否生效
[root@izwz9eftauv7x69f5jvi96z docker]# curl http://127.0.0.1:2375/info

如下图则表示正确
[root@localhost ~]# vim /usr/lib/systemd/system/docker.service
[root@localhost ~]# systemctl daemon-reload

[root@localhost ~]# systemctl restart docker.service
[root@localhost ~]# netstat -nlpt

2.整合idea

3.写一个测试类

@RestController
public class TestController {
   @GetMapping("test")
    public  String test(){
        return "hello docker";

    }
}

4.修改pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

        <relativePath/> <!-- lookup parent from repository -->

5.配置Dockerfile文件

#指定基础镜像，在其上进行定制
FROM java:8

#维护者信息
MAINTAINER cqd

#这里的 /tmp 目录就会在运行时自动挂载为匿名卷，任何向 /tmp 中写入的信息都不会记录进容器存储层
VOLUME /tmp

#复制上下文目录下的target/demo-1.0.0.jar 到容器里
COPY target/docker-0.0.1-SNAPSHOT.jar  docker-0.0.1.jar

#bash方式执行，使demo-1.0.0.jar可访问
#RUN新建立一层，在其上执行这些命令，执行结束后， commit 这一层的修改，构成新的镜像。
RUN bash -c "touch /docker-0.0.1.jar"

#声明运行时容器提供服务端口，这只是一个声明，在运行时并不会因为这个声明应用就会开启这个端口的服务
EXPOSE 8080

#指定容器启动程序及参数   <ENTRYPOINT> "<CMD>"
ENTRYPOINT ["java","-jar","docker-0.0.1.jar"]

6.创建docker镜像

7.启动

8.客户端访问

9.也可以直接用在docker客户端上直接执行：

[root@localhost ~]# docker run -p 28081:8080 --name cqd2 cqd/dockerdemo:1.0
