1. 安装docker:
2. 安装 dotnet: sudo yum install dotnet-sdk-5.0
3. mkdir webapi && cd webapi && dotnet new webapi && dotnet build && dotnet bin/Debug/net5.0/webapi.dll & (dotnet -h 可以查看帮助)。
4. wget https://localhost:5001/WeatherForecast --no-check-certificate 查看结果
5. 新建Dockerfile
#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.
