I am having some similar issues when trying to download Ignition on my Pi 4.
I used
sudo docker run -p 8088:8088 --name my-ignition -e GATEWAY_ADMIN_PASSWORD=password -e IGNITION_EDITION=full -d kcollins/ignition:nightly
which downloaded with no issues. However when I start the container it starts, but after a second it stops with an exit code 1. Is there any help you can offer.
