不能使用Spotify插件来构buildDocker镜像

我一直在使用Spotify插件来构buildDocker镜像，但由于某种原因，它突然停止工作，并且发出错误，抱怨Spotify插件上的exec失败

[INFO] [INFO] --- maven-jar-plugin:2.5:jar (default-jar) @ SimpleWebApp --- [INFO] Building jar: /home/test/opd_workspace/my_simple_webapp/target/SimpleWebApp-0.0.1-SNAPSHOT.jar [INFO] [INFO] --- spring-boot-maven-plugin:1.3.5.RELEASE:repackage (default) @ SimpleWebApp --- [INFO] [INFO] --- docker-maven-plugin:0.2.3:build (default-cli) @ SimpleWebApp --- SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

我的pom.xml插件非常简单，而且maven项目的构build和打包是可以的

 <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>0.2.3</version> <configuration> <imageName>${docker.image.prefix}/${project.artifactId}</imageName> <dockerDirectory>src/main/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> 

Answer 1

继线：

 [ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.2.3:build (default-cli) on project SimpleWebApp: Exception caught: Request error: POST unix://localhost:80/v1.12/build?t=imgprefix/SimpleWebApp: 500: HTTP 500 Internal Server Error -> [Help 1] 

看来你使用UNIX作为操作系统，而Docker你一个错误500。

我正在使用MACOS ，它完全适合我，与您的configuration相同，但是在我需要在terminal中评估Docker环境variables之前：

 eval $(docker-machine env default) 

Answer 2

使用该库，不能使用大写的存储库名称。 只允许[a-z0-9-_。]。

所以改变

SimpleWebApp

至

简单web应用程序

或类似的东西。
