Suggestion: Traefik dynamic configuration provider #288

Open thielj opened 2 months ago

thielj commented 2 months ago

Right now, enabling services for use with sablier requires managing configuration in various locations as Traefik discards dynamic configuration obtained from docker when a container is stopped.

An alternative would be for sablier to provide this information. I don't know if it's possible through the plugin, but providing an HTTP end point scraped by Traefik every few seconds would work.

It's an interesting solution indeed. Thanks for proposing that.

However, this behavior is really for a specific usage of traefik.

Note that in future releases of traefik, you should be able to use Sablier labels just like traefik labels to register the plugin configuration.

And as you mentioned, currently stopped containers will be discarded from the pool so you have to configure this in files and it may not be practical for you.

Now, this behavior has been identified as a bug in traefik: see https://github.com/traefik/traefik/issues/9907#issue-1725043940

If I have time, I will fix the issue on the Traefik repository.

So instead of developing a scraper, I'd recommend you to wait for the option to be available for Traefik.

Does that make sense ?

traefik maintainers have questions on changing allowEmptyServices, what do you think?

btw this is not to pressure you, but maybe their reply slipped your mind in a busy period or the like, it happens all the time to me

Hello @aless3, thanks for your interest in the project :)

I'm currently busy on a lot of other things in my life, I'll be able to work on the project soon enough.

I'm also using traefik and docker and I'm looking forward to be able to use sablier on my own services :D
