问题描述
我自己就遇到了这个问题。我认为dotnet watch
run与localhost类型的url配合不好。尝试https://0.0.0.0:5000在您的容器中将托管网址设置为。
在dockerfile中，带有：
ENTRYPOINT [ "dotnet", "watch", "run", "--no-restore", "--urls", "https://0.0.0.0:5000"]
或在launchSettings.json中，例如：
{
"profiles": {
"[Put your project name here]": {
"commandName": "Project",
"launchbrowser": true,
"environmentvariables": {
"ASPNETCORE_ENVIRONMENT": "Development",
"DOTNET_USE_POLLING_FILE_WATCHER": "true"
},
"applicationUrl": "https://0.0.0.0:5000/"
}
}
}
现在，要使其自动从容器中重新加载，您必须使用轮询文件监视程序。这就是第二个环境变量的用途。（这很常见，您必须使用webpack，angular等来执行此操作）。
在您的情况下，您需要将更esportsapp.volume改为主机上的目录：
volumes:
- ./:/app
它将容器中的/ app卷映射到docker-compose目录。您面临的问题是该应用程序内置在项目默认的docker- compose网络上的某个卷中，因此，当您在源目录中更改文件时，该卷中实际上并没有更改。但是，使用此修复程序，您将遇到容器内部dotnet恢复和dotnet监视更改主机文件的问题。如果您有兴趣，可以解决所有问题…
要调试，请运行： docker-compose -f run.yml up --build
要构建发行版： docker-compose -f build.yml up --build
/ # source control root
/build.yml # docker-compose file for building a release
/run.yml # docker-compose file for running locally & debugging
/project # an application
/project/build.Dockerfile # the docker container that will build "project" for release
/project/run.Dockerfile # the docker container that will build and run "project" locally for debugging
/project/.dockerignore # speeds up container builds by excluding large directories like "packages" or "node_modules"
/project/src # where I hide my source codez
/project/src/Project.sln
/project/src/Project/Project.csproj
/project/src/Project/Directory.Build.props # keeps a docker mapped volume from overwriting .dlls on your host
/project/src/Project.Data/Project.Data.csproj # typical .Net project structure
/web-api # another application...
（将其与.csproj放在同一文件夹中，dotnet watch
run以免使命令与主机上的源目录混淆）
<Project>
<PropertyGroup>
<DefaultItemExcludes>$(DefaultItemExcludes);$(MSBuildProjectDirectory)/obj/**/*</DefaultItemExcludes>
<DefaultItemExcludes>$(DefaultItemExcludes);$(MSBuildProjectDirectory)/bin/**/*</DefaultItemExcludes>
</PropertyGroup>
<PropertyGroup Condition="'$(DOTNET_RUNNING_IN_CONTAINER)' == 'true'">
<BaseIntermediateOutputPath>$(MSBuildProjectDirectory)/obj/container/</BaseIntermediateOutputPath>
<BaSEOutputPath>$(MSBuildProjectDirectory)/bin/container/</BaSEOutputPath>
</PropertyGroup>
<PropertyGroup Condition="'$(DOTNET_RUNNING_IN_CONTAINER)' != 'true'">
<BaseIntermediateOutputPath>$(MSBuildProjectDirectory)/obj/local/</BaseIntermediateOutputPath>
<BaSEOutputPath>$(MSBuildProjectDirectory)/bin/local/</BaSEOutputPath>
</PropertyGroup>

（用于调试的docker-compose.yml）
version: "3.5"
services:
project:
build:
context: ./project
dockerfile: run.Dockerfile
ports:
- 5000:80
volumes:
- ./project/src/Project:/app
（用于调试的Dockerfile）
FROM microsoft/dotnet:2.1-sdk
# install the .net core debugger
RUN apt-get update
RUN apt-get -y --no-install-recommends install unzip
RUN apt-get -y --no-install-recommends install procps
RUN rm -rf /var/lib/apt/lists/*
RUN curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l /vsdbg
VOLUME /app
workdir /app
CMD dotnet watch run --urls http://0.0.0.0:80
（用于构建发行版的docker-compose.yml）
version: "3.5"
services:
project:
build:
context: ./project
dockerfile: build.Dockerfile
volumes:
- ./project:/app
（用于构建发行版的Dockerfile）
FROM microsoft/dotnet:2.1-sdk
VOLUME /app
# restore as a separate layer to speed up builds
workdir /src
copY src/Project/Project.csproj .
RUN dotnet restore
copY src/Project/ .
CMD dotnet publish -c Release -o /app/out/
解决方法
如标题所示，我有一个无法从主机端口绑定到容器端口的容器。我尝试搜索类似的问题，但是自从Microsoft
microsoft/dotnet在sdk映像中引入了带有dotnet watch 的docker repo
以来，没有发现与在docker容器中使用dotnet watch相关的任何信息。
对于我在做什么错的任何建议，我们将不胜感激。
