Why is my service "Unable to start Kestrel" in EKS only?
Microsoft.AspNetCore.Server.Kestrel[0] Unable to start Kestrel. System.Net.Sockets.SocketException (13): Permission denied at
Looks like your container did not have enough permissions to listen on the port that you want.
In Linux, you typically need privileged permissions to listen to a port 1024 and lover. I suggest that you change your app to listen to port 8080 and 8433 instead. You can have a Service that expose port 80 but map that to targetPort 8080.
