I have 4 containers setup for Immich:

immich
immich-database
immich-machine-learning
immich-redis

However my Immich container fails to start on boot. And I read in the error log that has to do with the immich-database not finishing starting.

You are missing an After= for your database and redis containers.

Worked! Thank you :)
