I’ve also tried to run the docker compose file with not changes from the Zitadel documentation, zitadel.com/docs/self-hosting/deploy/compose

This is what shows:

[+] Running 3/3

dependency failed to start: container root-db-1 is unhealthy

docker ps -a then shows the root-zitadel-1 container created but not started, I can’t get any logs to show on the root-db-1 container even though it shows as running…

I start the root-zitadel-1 container and restart the root-db-1 container and this is what I get in the logs:
