Question

我正在尝试在我的项目上执行 mvn clean package docker:build 它失败并出现以下错误

这是我的 Dockerfile

FROM openjdk:8u131-jdk-alpine
ENV targetDir /usr/local/access-management-app-1.0.0-SNAPSHOT.jar
ENV srcDir .
ENV jarFile mma-access-management-app-1.0.0-SNAPSHOT.jar
RUN mkdir ${targetDir}
COPY ${srcDir}/${jarFile} ${targetDir}
WORKDIR ${targetDir}
CMD ["java", "-jar", "mma-access-management-app-1.0.0-SNAPSHOT.jar"]
EXPOSE 8080/tcp

我不知道哪里出了问题。我还尝试使用 spotify 的 dockerfile 插件，但也失败了。

Answer 1

maven 构建的 jar 文件 ${project.build.finalName}.jar 与您在 Dockerfile 中定义的不同。

调整Dockerfile中指定的jar文件名，使其与maven构建的jar匹配即可。

FROM openjdk:8u131-jdk-alpine
ENV targetDir /usr/local/access-management-auth-server-1.0.0-SNAPSHOT.jar
ENV srcDir .
ENV jarFile mma-access-management-auth-server-1.0.0-SNAPSHOT.jar
RUN mkdir ${targetDir}
COPY ${srcDir}/${jarFile} ${targetDir}
WORKDIR ${targetDir}
CMD ["java", "-jar", "mma-access-management-auth-server-1.0.0-SNAPSHOT.jar"]
EXPOSE 8080/tcp

Answer 2

看起来不像是 spotify 插件的问题。 docker 构建失败于 COPY ${srcDir}/${jarFile} ${targetDir} 我猜 srcDir 指向 src 文件夹，而 jar 将出现在 target 文件夹中。
