podman systemd service (with quadlet) starting a private container with ecr login

custom.sh

# custom.container
#
# This does login into ECR and starts a private container on boot with podman and quadlet / systemd.
# The container is running rootless, the systemd service is a 'user' service
# This is build to work on Fedora CoreOS, even the aws-cli does not need to be installed, it's used from aws public container repo. 
# You need to have valid aws credentials in ~/.aws/
# Replace the *** with your correct aws ecr url
#
# This file was partly generated with podlet
#
# Store in: ~/.config/containers/systemd/custom.container (create the dir if it does not exist)
#
# systemctl --user daemon-reload
# systemctl --user start custom.service
# systemctl --user status custom.service
# journalctl --user -fu custom.service
