Question

我一直在使用spotify插件来构建docker图像，但由于某种原因它突然停止工作，并且它在spotify插件上发出错误抱怨exec失败

我的pom.xml插件非常简单，maven项目构建和包也没问题

<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>

                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>

Answer 1

关注这一行：

[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]

您似乎使用UNIX作为操作系统，Docker会回答错误500.

我正在使用MACOS并且它与我的配置完全相同，但在我需要在终端中评估Docker环境变量之前：

eval $(docker-machine env default)

Answer 2

使用该库，您无法使用大写的存储库名称。只允许[a-z0-9-_。]。

所以改变

SimpleWebApp

到

简单web应用

或类似的东西。

无法使用spotify插件构建Docker镜像
