如何使用 Docker 使用 IIS 托管 Blazor 应用程序？

Question

我正在尝试创建一个包含 IIS 的容器，该 IIS 用于托管我的 blazor 应用程序。

我使用静态 HTML 文件运行它，但是当我尝试托管 Blazor 应用程序时，我在浏览器中收到错误：

You do not have permission to view this directory or page.

或

The page cannot be displayed because an internal server error has occurred.

当我重新启动容器并查看日志时，我得到以下信息：

Service 'w3svc' has been stopped

APPCMD failed with error code 4312

Failed to update IIS configuration

当我使用一种解决方法来创建自己的入口点并启动w3svc 时，我陷入了无限循环。 我当前的 dockerfile

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-20191210-windowsservercore-ltsc2019

COPY ./dotnet/dotnet-hosting-3.1.0-win.exe .
RUN powershell ./dotnet-hosting-3.1.0-win.exe /quiet /install

RUN powershell -NoProfile -Command Remove-Item -Recurse C:\inetpub\wwwroot\*
WORKDIR /inetpub/wwwroot
COPY ./output . # Contains compiled blazor hello world project

COPY ./config.ps1 .
RUN powershell ./config.ps1 # Creates new app and pool

COPY ./ContainerRunTime.ps1 .
ENTRYPOINT ./ContainerRunTime.ps1 # C:\\ServiceMonitor.exe w3svc

我的操作系统是 WinServer 2019

我终于使它与以下 Dockerfile 一起工作。

将此 Dockerfile 复制到项目的根目录中，重要的是项目有自己的 projectforlder。

# Use iis as base image and install dotnet 3.0.1 hosting pack
FROM microsoft/iis as base
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'Continue'; $verbosePreference='Continue';"]

# Use dotnet core sdk as build image 
FROM mcr.microsoft.com/dotnet/core/sdk:3.0 AS build
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.sln ./
COPY ./{PROJECT_NAME}/*.csproj ./{PROJECT_NAME}/
RUN dotnet restore

# Copy everything else and build app
COPY ./{PROJECT_NAME}/. ./{PROJECT_NAME}/

# Create final image

WORKDIR /inetpub/wwwroot/{PROJECT_NAME}

RUN Import-Module WebAdministration
RUN Remove-Website -Name 'Default Web Site'

# Create pool
RUN New-WebAppPool -Name '{PROJECT_NAME}-pool'; \
    Set-ItemProperty IIS:\AppPools\{PROJECT_NAME}-pool -Name managedRuntimeVersion -Value ''; \
    Set-ItemProperty IIS:\AppPools\{PROJECT_NAME}-pool -Name enable32BitAppOnWin64 -Value 0; \
    Set-ItemProperty IIS:\AppPools\{PROJECT_NAME}-pool -Name processModel.identityType -Value Service
# Create new Website
RUN New-Website -Name '{PROJECT_NAME}' \
    -Port 80 -PhysicalPath 'C:\inetpub\wwwroot\{PROJECT_NAME}' \
    -ApplicationPool '{PROJECT_NAME}-pool' -force

# Copy output from build img
COPY --from=build /app/out .

EXPOSE 80

现在将所有{PROJECT_NAME} 替换为您的项目名称并创建并启动容器：

docker build -t blazor-iis .
docker run -d -p 8080:80 --name blazor-iis-container blazor-iis

现在您可以在 chrome 中打开您的应用了

start chrome $(docker inspect -f "{{ .NetworkSettings.Networks.nat.IPAddress }}" "blazor-iis-container")
