Moved from Windows/WSL/Ubuntu to RPi 4b Ubuntu 64 and container fails on startup

[smseidl]

It's not producing much error details only: email2pdf | standard_init_linux.go:228: exec user process caused: exec format error

My compose section:

  email2pdf:
    image: ghcr.io/rob-luke/emails-html-to-pdf:latest
    container_name: email2pdf
    environment:

Initially I thought it might be something to do with https://stackoverflow.com/questions/42494853/standard-init-linux-go178-exec-user-process-caused-exec-format-error but I checked and the runner.sh file has a #!. I will keep digging.

What happens if you pin to an earlier version rather than latest?

Still getting below when I reference v0.1.0. I don't think there are other tags to use. I was reading that same post last night... is the problem that you haven't built the ARM/AMD version that matches RPi 4? See lower answer in that post here

I've tried to build locally, and am getting errors with the apt install of wkhtmltox. I can't seem to find the right architecture

I may have gotten it working today on my Pi 4B. Here is the Dockerfile I needed to use. I'm not sure how you'd add this into your master. I'm going to have this running for a while and will update here with my findings.
