Docker 29 incompatability with traefik 2.11

1

Heads up for anyone running off upstream docker. The recent Docker 29 release has changed a minimum API version that breaks compatibility with the current traefik version 2.11 selected by RhodeCode.

Lots of complaints and some workarounds on the traefik bugtracker.

Results in router stack logs:

traefik-1             | time="2025-11-11T15:50:12Z" level=error msg="Failed to retrieve information of the docker client and server host: Error response from daemon: client version 1.24 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version" providerName=docker

You can temporary apply this workaround:

Which leads to:

And the workaround consists of adding:

"min-api-version": "1.24"

to the daemon.json file, usually located at /etc/docker (you can create one if it does not exist)

Thanks for the info! We’re working on migration to traefik 3.X ATM should be solved soon !

New rcstack released now uses traefik v3 that is compatible with latest docker
