 There are two ways to respond to this breaking change:
 
-- Recommended: Explicitly set the `ASPNETCORE_HTTP_PORTS`, `ASPNETCORE_HTTPS_PORTS`, and `ASPNETCORE_URLS` environment variables to the desired port. Example: `docker run --rm -it -p 9999:80 -e ASPNETCORE_HTTP_PORTS=80 <my-app>`
-- Update existing commands and configuration that rely on the expected default port of port 80 to reference port 8080 instead. Example: `docker run --rm -it -p 9999:8080 <my-app>`
+- (Recommended action) Explicitly set the `ASPNETCORE_HTTP_PORTS`, `ASPNETCORE_HTTPS_PORTS`, and `ASPNETCORE_URLS` environment variables to the desired port. Example: `docker run --rm -it -p 8000:80 -e ASPNETCORE_HTTP_PORTS=80 <my-app>`

+If your app was built using the older <xref:Microsoft.AspNetCore.WebHost.CreateDefaultBuilder?displayProperty=nameWithType> method, set `ASPNETCORE_URLS` (not `ASPNETCORE_HTTP_PORTS`). Example: `docker run --rm -it -p 8000:80 -e ASPNETCORE_URLS=http://*:80 <my-app>`.
