Traefik 3.0 GA Has Landed: Here's How to Migrate (traefik.io)
from passepartout@feddit.de to selfhosted@lemmy.world on 01 May 00:24

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.

#selfhosted

threaded - newest

That’s great for them and good on you for upgrading. After the upgrade from v1 to v2, I switched to caddy. Traefik was too much for me.

Nothing wrong with that, Caddy is great!

I wish nginx had the concept of default header values for reverse proxies…

I mean, you can kind of do it with macros but man…

jkrtn@lemmy.ml on 01 May 11:56 collapse

Damn, same, nuked Traefik when v2 broke the setup I spent hours trying to figure out. I don’t think the concepts are overwhelming, but something is profoundly wrong with their documentation habits. Now someone in the comments here is saying v3 changes the way paths are read with regex? Lol, fuck Traefik, never again.

Awesome! Just updated without issues, I only had to make one tiny change to my config.

jenny_ball@lemmy.world on 01 May 06:36 next collapse

gui yet?

Appoxo@lemmy.dbzer0.com on 01 May 10:17 collapse

Yaml is better. But it has a dashboard.

chiisana@lemmy.chiisana.net on 01 May 10:44 collapse

Not necessarily just yaml — there are things yaml cannot do well, but even ignoring that, traefik can also use toml, or container labels — but rather, the entire concept of infrastructure as code is way better than GUIs. Infrastructure as code allows for much better linting, testing, and version controls thereby providing better stability and reproducibility.

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.

sxt@lemmy.world on 01 May 07:14 next collapse

All I had to do was remove one field to do with docker swarm which I don’t think I was using anyway.

Strit@lemmy.linuxuserspace.show on 01 May 07:28 collapse

Cool. I don’t have any swarm related config stuff.

PathPrefix no longer being regex stood out

Kata1yst@kbin.social on 01 May 11:29 next collapse

For real? Damn it that's going to be painful.

Lem453@lemmy.ca on 01 May 18:11 collapse

Sounds like they actually changed it to Go language regex syntax instead of pearl syntax.

The documentation certainly makes it sounds like they just got rid of regex but this forum post seems to show otherwise.

I’m definitely in the wait for a month at least before attempting this upgrade camp…

timbuck2themoon@sh.itjust.works on 01 May 08:36 next collapse

I might give this a go. Have been using bog standard ingress nginx for my k8s but have wanted to try a gateway supporting ingress product for a while.

Thanks op.

Appoxo@lemmy.dbzer0.com on 01 May 10:17 collapse

He… give it a Go. ;)

Decronym@lemmy.decronym.xyz on 01 May 08:45 next collapse

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

Fewer Letters More Letters
HTTP Hypertext Transfer Protocol, the Web
k8s Kubernetes container management package
nginx Popular HTTP server

2 acronyms in this thread; the most compressed thread commented on today has 11 acronyms.

Found it out the hard way because I have automatic updates with watchtower… xD

passepartout@feddit.de on 01 May 10:35 next collapse

I hope it went well :) i was completely ready to go back changing the image tag to v2 but didn’t need to.

Appoxo@lemmy.dbzer0.com on 01 May 14:54 collapse

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)_/¯

thegreekgeek@midwest.social on 01 May 12:14 next collapse

Oof, that’s what killed my V1 setup lol

MangoPenguin@lemmy.blahaj.zone on 01 May 22:24 collapse

Definitely worth using specific versions on your docker images if you’re doing automatic updates.

traefik:mimolette for example should keep you on 2.x versions while still getting patches and bug fixes.

Appoxo@lemmy.dbzer0.com on 02 May 05:05 collapse

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

MangoPenguin@lemmy.blahaj.zone on 02 May 13:16 collapse

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.

rsolva@lemmy.world on 01 May 15:07 collapse

Does it support Podman yet?
