Docker图像无声地无法启动
以下Docker映像成功构建但不会运行 - 没有任何（可见）错误：
FROM alpine:3
RUN apk --no-cache add transmission-cli transmission-daemon \
&& mkdir -p /transmission/config \
&& chmod -R 777 /transmission
RUN apk add --no-cache --upgrade bash
RUN wget -P ./transmission/ https://speed.hetzner.de/100MB.bin
ENV TRACKER_URL="http://104.219.73.18:6969/announce"
RUN echo tracker url is: ${TRACKER_URL}
RUN transmission-create -t ${TRACKER_URL} -o ./transmission/testfile.torrent /transmission/100MB.bin
CMD transmission-daemon -c ./transmission --config-dir ./transmission/
logs对我没有任何显示。奇怪的是：如果我构建图像，在其中运行外壳并执行cmd，一切都很好。我已经尝试将cmd包装在bash脚本中，并执行了（因为为什么），但结果相同。
我想念什么？
The following docker image successfully builds but will just not run - without any (visible) error:
FROM alpine:3
RUN apk --no-cache add transmission-cli transmission-daemon \
&& mkdir -p /transmission/config \
&& chmod -R 777 /transmission
RUN apk add --no-cache --upgrade bash
RUN wget -P ./transmission/ https://speed.hetzner.de/100MB.bin
ENV TRACKER_URL="http://104.219.73.18:6969/announce"
RUN echo tracker url is: ${TRACKER_URL}
RUN transmission-create -t ${TRACKER_URL} -o ./transmission/testfile.torrent /transmission/100MB.bin
CMD transmission-daemon -c ./transmission --config-dir ./transmission/
The logs show nothing for me. What's strange: If I build the image, run a shell inside it and execute the CMD, everything runs just fine. I've already tried wrapping the CMD in a bash script and executed that (because why not), but with the same result.
What am I missing?

如果您在命令行上运行
trainmission-daemon自己，您会发现它会将自己置于后台。从Docker的角度来看，您的容器刚刚退出！您需要将
-f（- 前景）添加到tranmission-daemon命令行：If you run
tranmission-daemonyourself on the command line, you'll see that it puts itself into the background. From Docker's perspective, your container just exited!You need to add the
-f(--foreground) option to yourtranmission-daemoncommand line:
