[英]Dotnet watch failing in docker-compose
我最近不得不更新 docker(2.2.0.0 穩定版 42247),現在我在使用docker-compose
在 docker 容器中運行dotnet watch
時遇到問題。
我的工作流程是將解決方案目錄(在主機上)掛載到在相關項目上運行dotnet watch
的 docker 容器上,初始版本看起來有點像這樣:
./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"]
它會成功運行。 更新后,我收到以下錯誤:
docker-compose up --build --force-recreate my-api

此輸出以及我的臨時解決方法表明,這與無法弄清楚 cwd 或 pwd 是什么有關,而不是 dotnet watch 的問題。 解決方法如下:
./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"]
跑:
docker-compose up --build --force-recreate search-api

Step 1/3 : FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS base

然后運行:
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
...
另外運行類似的東西
FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS base
ARG PROJECT
WORKDIR ${PROJECT}
ENTRYPOINT ["dotnet", "fsx"]
會產生非常相似的錯誤
docker-compose up --build --force-recreate my-api

我沒有使用特定版本,並且看到 github 問題帖子說要將您的版本降低到 2.1 某些東西。 但是,如果其他人出現,這里有一個 3.1.404 版本,它可以為您指明正確的方向。
Dockerfile.dev
FROM mcr.microsoft.com/dotnet/core/sdk:3.1.404-buster
WORKDIR /app
COPY *.sln ./
COPY *.csproj ./
RUN dotnet restore
ENTRYPOINT ["dotnet","watch","run","--no-launch-profile"]
和撰寫文件
version: "3.8"
services:
aspnet_service:
container_name: aspnet_dev_container
restart: always
hostname: api
build:
context: .
dockerfile: ./Docker/api/Dockerfile.dev
environment:

- ASPNETCORE_ENVIRONMENT=Development
ports:

mode: host
- target: 443

working_dir: /app
stdin_open: true
tty: true
command: dotnet watch run --no-launch-profile
稍微介紹一下,如果您願意,此 docker-compose 還可以讓您在本地使用 https 證書。 Build: dockerfile 部分只是我的 dockerfile 的路徑,而上下文是項目的根。
卷
--no-launch-profile
對我--no-launch-profile
,所以我把它保留在--no-restore
就像我在其他讓我失敗的項目示例中看到的那樣。
我找不到有關如何使 https 工作的帖子,但如果您希望我編輯此回復並將其添加進來,請發表評論,我會的。 我省略了它,因為它與問題無關。
