After 5 years of development, the wait is finally over: Traefik 3.0 is generally available! This article will focus on the beginning, the elephant in the room: the migration.
Upgrade went mostly without a problem (had set more than one Hostname for a service before, seems to not work anymore lol), and i have a pretty large configuration that has grown over the past two years.
What i noticed is that it is quite a bit faster. Also the dashboard shows a little more information than before and the logs have colours now.
Juat an error due to the swarmRefresh setting in the traefik.yml.
Because I am not running in swarm mode it threw an error.
Oh well. Life and learn ¯\_(ツ)_/¯
Yeah…I should be doing it but I am honestly too lazy to change my compose.
The only place I actually did it is my mongodb container bexause I know absolutely nothing about it.
At lwast I can rescue my traefik config :p

Found it out the hard way because I have automatic updates with watchtower… xD
I hope it went well :) i was completely ready to go back changing the image tag to v2 but didn’t need to.

Oof, that’s what killed my V1 setup lol
Definitely worth using specific versions on your docker images if you’re doing automatic updates.
traefik:mimolettefor example should keep you on 2.x versions while still getting patches and bug fixes.Yeah…I should be doing it but I am honestly too lazy to change my compose.

I mean same, I say it’s worth using but I don’t do it either haha.
Everything is backed up every night, so if something breaks to the point of data loss I just fix it after.
