Asp.net-core – Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found

In later .net core versions a *.csproj file is used instead of the project.json file.

You can modify the file to get the desired result by adding:

   <ItemGroup>
      <Content Update="appsettings.json">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      </Content>
   </ItemGroup>

As soon as you've setup the certificate in nginx, I see no sense enabling it in the asp.net core container as your docker network is going to be visible to public via nginx.

To disable Kestrel Https listening just remove 443 port from the following code:

- ASPNETCORE_URLS=https://+:443;http://+:80

Replace it with:

- ASPNETCORE_URLS=http://+:80
