Hi @Harshanand Wankhede ,

Thanks for reaching out.

I understand you are getting error while deploying the ASP.Net core applications with Docker over HTTPS

Docker needs a certificate to process HTTPS requests.
Below are the steps you required to deploy the ASP.net core with docker are:

1. Create the certificate. Make sure to set the password to use the certificate with docker.
2. Provide the certificate to the docker image.

Reference sample: https://github.com/dotnet/dotnet-docker/blob/main/samples/run-aspnetcore-https-development.md

Hope this will help.

Thanks,
Shweta

You have to use volumes in docker-compose.yml to point out the location of ssl certificate. This tutorial will help you - Deploy a Docker based ASP.NET Core app to Azure

While you can store a ssl certificate in azure key value, docker does not directly support this. You need to export the certificate to the proper location for docker.
