1.修改docker配置文件，打开2375端口

[root@s162 docker]# vim /usr/lib/systemd/system/docker.service
#查找 ExecStart，在末尾添加
#后面加上-H tcp://0.0.0.0:2375 

[root@s162 docker]# systemctl daemon-reload
[root@s162 docker]# systemctl start docker

## 查看2375端口是否启用
[root@s162 docker]# lsof -i:2375
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
dockerd 27021 root 5u IPv6 352598799  0t0 TCP *:2375 (LISTEN)

2. Idea安装配置docker插件

2.1. idea-plugins市场安装docker插件

略…

2.2. 配置docker

3.springboot项目部署到docker服务器

3.1. 编写docker/dockerfile

3.2.maven添加docker-maven-plugin插件

 
   com.spotify
   docker-maven-plugin
   1.0.0
   
    
    jhs/${project.artifactId}:${project.version}
    
    

    
    ${project.basedir}/docker
    
    http://192.168.129.162:2375


    
    
     
      /
      ${project.build.directory}
      ${project.build.finalName}.jar
     
    


    
    
     target/${project.build.finalName}.jar
    
   
  

3.3. docker:build

使用命令$ mvn clean package docker:build -Dmaven.test.skip=true构建镜像，在docker服务器上查看镜像是否上传成功：

3.4 docker:tag

docker命令行格式为：#docker tag :/:

插件配置
补充配置：

 
	 jhs/${project.artifactId}:${project.version}
  
  192.168.129.160:5000/${project.artifactId}:${project.version}

为镜像打上tag标签，为后续的push做准备：mvn clean docker:tag -Dmaven.test.skip=true -DskipDockerBuild

3.5 docker:push

插件配置
补充配置：

	 
  
  nexus-docker-registry
  192.168.129.160:5000
  	
  	
		192.168.129.160:5000/${project.artifactId}

将上文打上tag标签的镜像，推送到私服nexus：mvn clean docker:push -Dmaven.test.skip=true -DskipDockerBuild -DskipDockerTag

3.6 docker插件参数

• -DskipDockerBuild to skip image build
• -DskipDockerTag to skip image tag
• -DskipDockerPush to skip image push
• -DskipDockerto skip any Docker goals

3.7 绑定命令到maven phases

  
   build-image
   package
   
    build
   
  

  
   tag-image
   package
   
    tag
   
   
    jhs/${project.artifactId}:${project.version}
    192.168.129.160:5000/${project.artifactId}:${project.version}
   
  


  
   push-image
   deploy
   
    push
   
   
    
    
    nexus-docker-registry
    192.168.129.160:5000
    192.168.129.160:5000/${project.artifactId}
   
  

 

3.8 最佳实践

 
  http://192.168.129.162:2375
  192.168.129.160:5000
