如何從 Windows 主機連接到 wsl2 內 docker 容器內的應用程序？

Question

在 Windows 上：

我剛剛通過dotnet new mvc創建了應用程序並為此創建了 Dockerfile：

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY ["src/App.csproj", "src/"]
RUN dotnet restore "src/App.csproj"
COPY . .
WORKDIR "/src/src"
RUN dotnet build "App.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "App.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "App.dll"]

然后我打開 wsl2，進入/mnt/d/myproject並構建了docker build -t app. 並開始了它。

我看到它在運行

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
9e17cbwe6e4c        test1               "dotnet App.dll"    5 days ago          Up About a minute   80/tcp, 443/tcp     affectionate_goldstine

還有正確的日志：

[10:54:13 WRN] Storing keys in a directory '/root/.aspnet/DataProtection-Keys' that may not be persisted outside of the container. Protected data will be unavailable when container is destroyed.
[10:54:13 INF] User profile is available. Using '/root/.aspnet/DataProtection-Keys' as key repository; keys will not be encrypted at rest.
[10:54:13 INF] Now listening on: http://[::]:80
[10:54:13 INF] Application started. Press Ctrl+C to shut down.
[10:54:13 INF] Hosting environment: Production
[10:54:13 INF] Content root path: /app/

但我不確定如何連接到它？

Answer 1

您需要使用 -p 公開端口

docker run -itd --name myapp -p 80:80 <image>

然后您可以通過host_ip:80訪問您的應用
