Not able to change maxconn backend configuration from marathon labels

[migueleliasweb]

This is the example confif from https://docs.traefik.io/toml/

I could not find a way to change maxconn from marathon labels.

Tried:

• traefik.backend.maxconn with value amount=1000
• traefik.backend.(mybackendname).maxconn with value amount=1000
• traefik.backend.maxconn.amount with value 1000

None of them worked. =/

What I did wrong ?

[Example toml from docs]

# rules
[backends]
  [backends.backend1]
    [backends.backend1.circuitbreaker]
      expression = "NetworkErrorRatio() > 0.5"
    [backends.backend1.servers.server1]
    url = "http://172.17.0.2:80"
    weight = 10
    [backends.backend1.servers.server2]
    url = "http://172.17.0.3:80"
    weight = 1
  [backends.backend2]
    [backends.backend1.maxconn]
      amount = 10
      extractorfunc = "request.host"

It appears that Traefik isn't yet reading any labels to set maxconn values (see: template, provider code.) I'll take a stab at this.

[migueleliasweb]

I think the same happens on some other labels. I compared marathon provider with the file provider and seems to me that some other configurations are missing...

Anyway, thanks @jangie !

Yeah, aside from maxconn, it appears that circuit breaker and which specific loadbalancer algorithm are the two missing currently from the marathon provider's Backend configurability. I plan on adding those in soon, perhaps in the existing PR I have for maxconn.

🎉 Perfect ! That would help a lot !

Ps(edit): I actually know Go but I could not help much with this issue because I had a lot of trouble trying to create a development environment for Traefik. Maybe some docs to help with build would make more people help directly with PRs !

[jangie]

yeah... this past weekend was honestly my first stab at playing with go or with traefik's code and i had some trouble getting myself setup. i'm not even entirely sure i'm setup fully at this point (ha) but i was at least able to test that maxconn is settable via labels in my fork and will be able to do likewise for the other items. if i get some time maybe i'll try setting up from scratch and take notes.
