Spring Boot和Docker-compose设置参数
Spring Boot和Docker-compose设置参数
提问于 2018-06-19 23:41:33
我可能是docker领域的新手，并尝试将我的Spring-Boot项目与docker和docker-compose结合起来，但不知何故docker-compose不起作用。
我使用的是spring boot文档中描述的com.spotify maven插件。我可以使用spotify插件构建和运行docker镜像，也可以使用docker命令从命令行构建和运行docker镜像，但当我尝试使用docker-compose up时不能。
在这里，我总是得到一个错误‘错误:无效或损坏的jarfile /app.jar’。
我确信这与ARG有关，它是从spotify插件传递给JAR_FILE命令的。我不知道如何在docker-compose.yml中设置这个ARG_FILE，这样我就可以从docker-compose up开始，并使用spotify插件只运行docker镜像。
下面是我的设置：
