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.
If I'm not doing anything fancy and just use it for basic reverse proxy stuff for my docker containers, would I need to change stuff in the configs? Most of the stuff mentioned in the migration guide is about tls.caOptional stuff, which I don't believe I use.
