Java docker jdk alpine 8上带有BusyBox消息的Spring微服务

我试图在docker的jdk alpine映像上运行Spring Cloud microservice，但在运行两个容器的过程中，我收到了以下消息：

licensingservice_1       | BusyBox v1.29.3 (2019-01-24 07:45:07 UTC) multi-call binary.
licensingservice_1       |
licensingservice_1       | Usage: basename FILE [SUFFIX]
licensingservice_1       |
licensingservice_1       | Strip directory path and .SUFFIX from FILE
licensingservice_1       | usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-O length]
licensingservice_1       |        [-P proxy_username] [-p source_port] [-q seconds] [-s source]
licensingservice_1       |        [-T toskeyword] [-V rtable] [-w timeout] [-X proxy_protocol]
licensingservice_1       |        [-x proxy_address[:port]] [destination] [port]

下面是用于构建映像的docker文件和run.sh文件

DockerFile

ADD @project.build.finalName@.jar /usr/local/licensingservice/
ADD run.sh run.sh
RUN chmod +x run.sh
CMD ./run.sh

run.sh

#!/bin/sh
getPort() {
    echo $1 | cut -d : -f 3 | xargs basename
}

我已经用带有spotify docker插件1.2.0的mvn clean package docker:build命令构建了这个图像

是什么设置了变量，比如

$EUREKASERVER\u PORT

？如果这些变量为空，我可以看到发生此错误。@DavidMaze我使用docker compose传递环境参数，看起来我忽略了其中一些参数，出现了这个奇怪的错误。谢谢你的帮助！是什么设置变量，如
