i am trying to move an aspnet core application to docker.Unfortunately i can't get the application run on port https 8081.I tried several things (see my config below) but when trying to open the app via https in the browser nothing happens (i don't even see an error in the container log files).
I managed to get the app working on http with port 8080 but not on https
Here are my configs so far:
Dockerfile:
I installed additional packages like curl to be able to get more details on running processes and internal http requests on port 8081.
#how to use the asp.net image as baseFROM mcr.microsoft.com/dotnet/aspnet:8.0 AS baseUSER appWORKDIR /appEXPOSE 8081FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base#Install the .NET Core runtimeCOPY --from=mcr.microsoft.com/dotnet/sdk:8.0 /usr/share/dotnet/sdk /usr/share/dotnet/sdk# Instlling the required packagesRUN apt-get update && apt-get install -y procps telnet curl iproute2 wgetThe certificate was made with openssl using the bash of the docker image and added to the kestrel config.

docker-compose.yml:

After the Docker image build i performed this steps in addition:
# Copy SSL certificates to the containercopied the localhost.crt to /usr/local/share/ca-certificates/# Update SSL certificates in the container bashupdate-ca-certificates
After enabling the certificates i finally got a reponse by using curl:
