Custom software installation / ubuntu2004

[runnerImages]

I've added a custom software installation script that installs Terragrunt in the image build.
Script is also including a simple test (as presented below).
It occurred that terragrunt is not available in the scale set instances deployed from custom image.

It is very important for me to have it installed in the image (same as i.e. terraform and other tools).
I've seen some discussions about installing it in the pipeline where terragrunt is used, but unfortunately I can't use that solution due to organizational procedures.

Could you please let me know what other steps should I perform to add extra software into the image?

As I see, you already adds custom script to packer template. So for now you need to set building environment and start build process. Here is step-by-step guide with explaining how to do it.

Thank you, I'll check it! :)

Thank you @sergei-pyshnoi for help. I've found the problem which was not related to the software installation.
