Podman comes with an auto-update flag you can set for containers that uses systemd to do this for you. Takes a bit of reading to get it right but its smooth sailing mostly.

[foresto]

Good to know, but my script is for a different workflow: It checks for updates to remote dependencies of my running custom containers. (For example, when alpine:latest points to something new.) It then prints a message for cron to email to me, noting that it's time to rebuild my custom stuff.
