Description

When upgrading to Docker 29.X.X, Traefik stops working because of Docker API version bump to min. 1.44 (before: 1.24), see https://github.com/traefik/traefik/issues/12253 . https://github.com/traefik/traefik/pull/12256 fixes this in Traefik v3.6.1.

The version bump fixes a non working installation or upgrade when using Crowdsec since the Crowdsec compose part uses a Docker Label which does not work in Traefik v3.5.X after the Docker upgrade to 29.X.X.

How to test?

Update Docker to 29.X.X with Traefik 3.5.X and Crowdsec enabled -> Pangolin and Resources do not work
Traefik Error: ERROR: CrowdsecBouncerTraefikPlugin: YYYY/MM/DD HH:MM:SS appsecQuery:unreachable

Upgrade to Traefik 3.6 -> Pangolin and Resources are working
