Do tnet смотреть сбой в docker -составить

/ 22 января 2020

Мне недавно пришлось обновить docker (2.2.0.0 stable 42247), и теперь у меня возникают проблемы с запуском dotnet watch в docker контейнере с использованием docker-compose.

Мой рабочий процесс заключается в монтировании каталога решения (на хосте) в контейнер docker, который запускает dotnet watch в соответствующем проекте, первоначальная версия выглядела примерно так:

./docker-compose.yml

version: "3.2"
services:
  my-api:
    build: 
      context: $MY_API_LOCATION_ON_HOST # the folder with the .sln file and all projects
      dockerfile: $DOCKERFILE_ROOT/Dockerfile-aspcore-dev
      args:
        PROJECT: app/src/MyApi # Where the .csproj will be
    volumes:
      - type: bind
        source: $MY_API_LOCATION_ON_HOST # the folder with the .sln file and all projects
        target: /app
      - type: bind
        source: $SECRETS_FOLDER # C:\Users\DevUser\AppData\Roaming\Microsoft\UserSecrets
        target: /root/.microsoft/usersecrets

./Dockerfile-aspcore-dev

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS base
ARG PROJECT
WORKDIR ${PROJECT}

ENTRYPOINT ["dotnet", "watch", "run", "--urls", "http://0.0.0.0:5000"]

, и он будет успешно работать. После обновления я получаю следующую ошибку: 

docker-compose up --build --force-recreate my-api

Этот вывод вместе с моим временным обходным решением предполагает, что это связано с неспособностью выяснить, что такое cwd или pwd, а не проблема с tnet смотреть. Обход выглядит так:

./docker-compose.yml

version: "3.2"
services:
  my-api:
+    tty: true
+    stdin_open: true
    working_dir: /app/src/MyApi # Where the .csproj will be
    build: 
      context: $MY_API_LOCATION_ON_HOST
      dockerfile: $DOCKERFILE_ROOT/Dockerfile-aspcore-dev
    volumes:
      - type: bind
        source: $MY_API_LOCATION_ON_HOST # the folder with the .sln file and all projects
        target: /app
      - type: bind
        source: $SECRETS_FOLDER # C:\Users\DevUser\AppData\Roaming\Microsoft\UserSecrets
        target: /root/.microsoft/usersecrets

./Dockerfile-aspcore-dev

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS base
ARG PROJECT
WORKDIR ${PROJECT}

- ENTRYPOINT ["dotnet", "watch", "run", "--urls", "http://0.0.0.0:5000"]

run: 

docker-compose up --build --force-recreate search-api

затем запустите : 

docker exec -it src_my-api_1 dotnet "watch" "run" "--urls" "http://0.0.0.0:5000"
watch : Polling file watcher is enabled
watch : Started
watch : Exited
watch : File changed: /app/src/MyApi/Constants.cs
watch : Started
...

дополнительно выполнение чего-то вроде 

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS base
ARG PROJECT
WORKDIR ${PROJECT}

ENTRYPOINT ["dotnet", "fsx"]

приведет к очень похожей ошибке 

docker-compose up --build --force-recreate my-api
