How to add Fonts in azure container?

Question

I have an application which I have deployed to Azure through docker image. Now I am facing one issue. This application sends an email with RDLC reports. But the reports I am getting in mail have different fonts than the report I am getting previously(without docker). I found that the base docker image mcr.microsoft.com/dotnet/framework/runtime:4.8-windowsservercore-ltsc2019 I am using does not have fonts loaded with it. I need to install fonts in my docker image/container. How can I do this?

Below is my Dockerfile commands:
FROM mcr.microsoft.com/dotnet/framework/runtime:4.8-windowsservercore-ltsc2019 AS BASE
COPY . .
ENTRYPOINT BackgroundService.exe

Thanks in advance

Answer

Welcome to Microsoft Q&A! Thanks for posting the question.

At the end of the Dockerfile, add the following line and save the file.
RUN ${source:-obj/Docker/publish/InstallFont.ps1}
-- InstallFont.ps1 is the file in the CustomFontSample project in the sample highlighted in the document, you may take a similar approach to install the font.

Additional for a reference, this example Docker File does the following:

Specifies a Long Term Servicing Channel base Windows Server 2019 Core image, i.e. mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019

Executes a PowerShell script to download and install the custom font within the container
