pom配置

 先在pom.xml加上插件,
	注意:docker服务器地址(默认docker.io)/docker注册名称/具体名称(docker服务器地址的值需要在settings.xml里有对应的配置,否则无法push到docker服务器)
  
 
	com.spotify
	dockerfile-maven-plugin
	1.4.10
	
		
			default
			
				build
				push
			
		
	
	
		true
		false 
		registry.hub.docker.com/${docker.registry.name}/${project.artifactId}				
		latest
		
			target/${project.build.finalName}.jar
		
	

settings.xml配置

docker服务器的用户名密码配置
id和上面的docker服务器地址地址一致
   
   	 
      docker.io
      297513458
      密码
    
    
      registry.hub.docker.com 
      297513458
      密码
    

在pom.xml同级目录加上Dockerfile
dockerfile 基础配置

FROM openjdk:8-jre
MAINTAINER wendao
#加载到docker的目录
VOLUME /tmp
ARG JAR_FILE
ADD ${JAR_FILE} /app/app.jar
WORKDIR /app/
EXPOSE 8080
ENTRYPOINT ["/usr/bin/java","-jar","./app.jar"]
命令,不处理docker:mvn clean package -Ddockerfile.skip
编译mvn clean package dockerfile:build
发布mvn clean package dockerfile:push或mvn clean deploy
