不再推荐用这篇文章的方法配置https，推荐用nginx反向代理ASP.NET Core然后在nginx上配ssl证书

错误重现一下：

新建了一个ASP.NET Core应用，在VS2017下添加Docker支持，选择Linux环境
然后再给这个web应用再右键添加容器业务流程协调程序支持，然后解决方案就多了一个docker-compose的项目

通过VS2017的调试是可以通过docker-compose启动web应用项目的，并且会弹出提示信任证书的提示，但是，在CMD或PowerShell中使用

docker-compose build
docker-compose up

　　却抛出Unable to start Kestrel.的错误提示

问题重现完成，我的解决方案如下：

Step 1. 编辑Dockerfile

 1 FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
 2 WORKDIR /app
 3 EXPOSE 80
 4 EXPOSE 443
 5 
 6 FROM microsoft/dotnet:2.1-sdk AS build
 7 WORKDIR /app
 8 RUN dotnet dev-certs https --clean
 9 RUN dotnet dev-certs https -ep ./WebApplication1.pfx  -p crypticpassword
10 WORKDIR /src
11 COPY WebApplication1/WebApplication1.csproj WebApplication1/
12 RUN dotnet restore WebApplication1/WebApplication1.csproj
13 COPY . .
14 WORKDIR /src/WebApplication1
15 RUN dotnet build WebApplication1.csproj -c Release -o /app
16 
17 FROM build AS publish
18 RUN dotnet publish WebApplication1.csproj -c Release -o /app
19 
20 FROM base AS final
21 WORKDIR /app
22 COPY --from=publish /app .
23 ENTRYPOINT ["dotnet", "WebApplication1.dll"]

步骤1主要在第6行后面加了如下操作：

1 FROM microsoft/dotnet:2.1-sdk AS build
2 WORKDIR /app
3 RUN dotnet dev-certs https --clean
4 RUN dotnet dev-certs https -ep ./WebApplication1.pfx  -p crypticpassword

Step 2.编辑docker-compose.override.yml

 1 version: '3.4'
 2 
 3 services:
 4   webapplication1:
 5     environment:
 6       - ASPNETCORE_ENVIRONMENT=Development
 7       - ASPNETCORE_URLS=https://+:443;http://+:80
 8       - ASPNETCORE_HTTPS_PORT=44380
 9       - ASPNETCORE_Kestrel__Certificates__Default__Password=crypticpassword
10       - ASPNETCORE_Kestrel__Certificates__Default__Path=./WebApplication1.pfx
11     ports:
12       - "62084:80"
13       - "44380:443"
14     volumes:
15       - ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro
16       - ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro

步骤2主要添加了两个环境变量：

1     environment:
2       - ASPNETCORE_Kestrel__Certificates__Default__Password=crypticpassword
3       - ASPNETCORE_Kestrel__Certificates__Default__Path=./WebApplication1.pfx

Step 3. 再次运行命令

1 docker-compose build
2 docker-compose up

1 Hosting environment: Development
2 Content root path: /app
3 Now listening on: https://[::]:443
4 Now listening on: http://[::]:80
5 Application started. Press Ctrl+C to shut down.

问题解决成功！
