无法在Docker Entrypoint命令中使用variables
我正在尝试构build一个dockerfile。 我以前尝试使用硬编码path为我的项目和输出是好的。 但是，一旦我开始使用一个variables，java代码停止执行。
Dockerfile
FROM java:7 EXPOSE 7100 ARG version ENV version=$version RUN echo $version RUN mkdir -p /cacheDir/services/live/prediction/p7100/$version/logs RUN ls -tlr /cacheDir/services/live/prediction/p7100/ RUN mkdir -p /cacheDir/services/releases/prediction/p7100/$version/ RUN mkdir -p /cacheDir/services/predictionmodel ADD target/predictionDependencies/star /cacheDir/services/predictionmodel/ #star here is the operator (*), it was being interpret as comments by this stackoverflow editor.

docker build --build-arg version=0.0.14-SNAPSHOT -t prediction:0.0.14-SNAPSHOT .
图像似乎是成功的。 但是，当我运行该命令时，容器就自行退出。 使用的运行命令：
docker run -p 7100:7100 -v ~/PredictionVolume/logs/:/cacheDir/services/live/prediction/p7100/0.0.14-SNAPSHOT/logs/ -t prediction:0.0.14-SNAPSHOT
当试图查看正在运行的容器时，它没有运行。
我尝试过使用这两种解决scheme，但没有一个能够解决问题。
如何在ENTRYPOINT数组中使用Docker环境variables？
其他的解决scheme是，我用这个replace下面的ENTRYPOINT命令。
ENTRYPOINT ["sh","-c","java","-server","-Xmx2g","-Xloggc:/cacheDir/services/live/prediction/p7100/${version}/logs/gc.log","-verbose:gc","-XX:+PrintGCDateStamps","-XX:+PrintGCDetails","-XX:+HeapDumpOnOutOfMemoryError","-XX:HeapDumpPath=/cacheDir/services/live/prediction/p7100/${version}/oom.dump","-Dlogback.configurationFile=/cacheDir/services/releases/prediction/p7100/${version}/logback.xml","-Dlog.home=/cacheDir/services/live/prediction/p7100/${version}/logs","-Dlogback.debug=true","-Dbroker.l^Ct=sv-kafka6.pv.sv.nextag.com:9092,sv-kafka7.pv.sv.nextag.com:9092,sv-kafka8.pv.sv.nextag.com:9092,sv-kafka9.pv.sv.nextag.com:9092","-jar","/cacheDir/services/releases/prediction/p7100/${version}/prediction-0.0.13-SNAPSHOT.jar","7100","/cacheDir/services/releases/prediction/p7100/${version}/instance.properties","/com/wizecommerce/services/qa","&"]
但是使用这个命令的输出就像在terminal上键入java一样，显示所有可用的选项将显示在屏幕（terminal）上。
任何人都可以请build议出路？ 谢谢！！！
尝试这个：
ENTRYPOINT ["sh","-c","java -server -Xmx2g ..."]
当你使用sh -c ，它需要一个单独的参数，就是要运行的命令，空格分隔参数，就像你在命令行input一样。 你目前只运行java ，并将一些额外的不适当的parameter passing给sh 。
此外，摆脱＆符号&最后 – 你不想尝试和背景的过程。
