maven+docker构建springboot时,报"POST unix://localhost:80/build?t="的错

具体报错如下:

[INFO] Copying /root/springcloudconfig2/EurekaClient/target/EurekaClient-0.0.1-SNAPSHOT.jar -> /root/springcloudconfig2/EurekaClient/target/docker/EurekaClient-0.0.1-SNAPSHOT.jar

产生错误的pom.xml:

        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
            
                com.spotify
                docker-maven-plugin
                0.4.3
               
                ${docker.image.prefix}/${project.artifactId}
                    /src/main/docker
                   
                       
                            /
                ${project.build.directory}
                            ${project.build.finalName}.jar
                       
                   
               
           
        
    
错误的原因

1.${docker.image.prefix}/${project.artifactId}

imagename中字母必须全部小写,我的${project.artifactId}中含有大写字母

2.  /src/main/docker


 路径改为${project.basedir}/src/main/docker

更改之后的pom.xml

        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
            
                com.spotify
                docker-maven-plugin
                0.4.3
               
                luo/ec
                    ${project.basedir}/src/main/docker
                   
                       
                            /
                ${project.build.directory}
                            ${project.build.finalName}.jar
                       
                   
               
           
        
    
最后构建成功

注意:

1.在项目的/src/main下创建一个docker目录,在docker目录下创建Dockerfile文件

2 Dockerfile

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD ./EurekaClient-0.0.1-SNAPSHOT.jar app.jar
#RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
EXPOSE 8761

ADD 指令后面的第一个路径是jar相对于/target/docker/Dockerfile的路径  第二个是容器中的路径
