Installing fonts for DotNet AWS Lambda

[genifycom]

I have read everything I can about this. I know that I could produce an AWS Linux 2 with fonts installed, but I would prefer to use the existing Lambda container.

I tried copying the fonts from /var/task/fonts/ to /usr/share/fonts/ but that target directory says it is read-only.

I could not use sudo with AWS Lambda.

I have tried using font.conf in the /var/task/fonts/ directory, but I guess I need fontconfig installed.

Has anyone managed to install a font in the DotNet Lambda environment? I could really use some help.

The end aim is to use ClosedXML in DotNet Lambda to generate an Excel file for Windows but I cannot get a Windows font installed.

Articles I have tried using:

https://stackoverflow.com/questions/46486261/include-custom-fonts-in-aws-lambda
https://linuxconfig.org/how-to-install-and-manage-fonts-on-linux

Approaches tried:

Running several Linux commands via System.Diagnostics.Process.

I would strongly encourage you to try and deploy the function as a container image where you will have much more control of what is installed. The only writable area in the filesystem in a zip based Lambda function is the /tmp directory.
