warn: Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]
Failed to determine the https port for redirect.
For the https redirection warning, I recommend simply removing the https redirection policy from the startup.cs file which is typically defined via app.UseHttpsRedirection(); unless you're actually using this policy for your container and in this case you'd need to actually setup the certificates and expose the HTTPS port on your container.
需要注释掉startip.cs里的app.UseHttpsRedirection()。
