Отладка Dockefile

Автор вопроса: S.H.

Я пишу контейнер, который соберет моё приложние.

Чтобы потом собранное приложение упаковать в другой контейнер для запуска.

Приблизительно Dockerfile для сборки выглядит так:

    #Dockerfile for build container for my app
    FROM mcr.microsoft.com/dotnet/sdk:6.0
    COPY ./MyApp /App/MyApp
    WORKDIR /App/MyApp
    RUN dotnet publish --runtime linux-musl-x64 --self-contained true -c release
    CMD mkdir /App/publish-output/
    CMD cp -r /App/MyApp/bin/Release/net6.0/linux-musl-x64/publish/* /App/publish-output

Потом я всё это запускаю таким sh - файлом:

    docker build -t make_myapp-image -f Dockerfile_build .
    docker run -it --name make_myapp-cont  -v ~/FsaRobots/publish-output:/App/publish-output -d make_myapp-image

Где то при сборке происходит ошибка. Мне нужно, чтобы после "docker run" контейнер не "умер", а остался в запущенном состоянии, и я мог приконнектиться туда docker exec'ом и просмотреть внутненнее состояние

Как мне это сделать?

я получил несколько бесполезных советов от chatgpt, связанных то с RUN sleep infinity, то с предложением написать какой то entrypoint.sh, но это всё не работает. я помню, что раньше я писал в произвольном месте Dockerfile просто "STOPSIGNAL SIGQUIT", и это работало как магическое заклинание "контейнер, стой, жди, когда я с тебе подключусь!".

Но сейчас я попробовал - не работает!

Что Вы посоветуете?

Спасибо!

UPDATE

проблема вашего контейнера в том, что нет такого пути bin/Release, есть путь bin/release.

Исходный ответ

Я попробовал ваш dockerfile в режиме простого run, без detached:

docker run --rm -it -v .\release:/App/publish-output make_myapp-image

Вот что увидел

cp: cannot stat '/App/MyApp/bin/Release/net6.0/linux-musl-x64/publish/*': No such file or directory

предлагаю вам поменять команду CMD вот на что

CMD cp -av /App/MyApp/bin/release/net6.0/linux-musl-x64/publish /App/publish-output/

тогда при запуске выводится

а в каталоге release, который был отмаплен на /App/publish-output/, появился каталог publish

теперь про exec. В контейнер, который построен из вашего Dockerfile, вы не сможете сделать exec так как контейнер сразу же завершается после выполнения команды. Вам нужно погрузить шелл в вечный сон, тогда контейнер не будет завершаться сразу после работы. Например, вот так.

CMD /bin/sh -c 'cp -vr /App/MyApp/bin/Release/net6.0/linux-musl-x64/publish/* /App/publish-output; sleep infinity'
