Traefik broken on OrbStack 2.1.0

[D3strukt0r]

Describe the bug

using something simple as just this

services:
  traefik:
    restart: unless-stopped
    image: 'traefik:2.10'
    container_name: traefik
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ~/.iwf-dev/config/traefik.yml:/etc/traefik/traefik.yml
      - ~/.iwf-dev/traefik/certs-conf:/etc/traefik/certs-conf
      - ~/.iwf-dev/traefik/certs:/certs
      - /var/run/docker.sock:/var/run/docker.sock
    networks:
      - web
    labels:
      - "traefik.http.routers.api.rule=Host(`traefik.test`) && PathPrefix(`/api`, `/dashboard`)"
      - "traefik.http.routers.api.service=api@internal"
      - "traefik.http.routers.api.tls=true"
      - "traefik.http.services.api.loadbalancer.server.port=8080"

  # The local DNS to resolve the *.test domains to 127.0.0.1 and all project specific configs in ~/.iwf-dev/dns
  # (for format see manpage: https://thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html)
  # install on MacOS with:
  # sudo mkdir -v /etc/resolver && sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/test'
  dns:
    restart: always
    image: 4km3/dnsmasq:latest
    container_name: dns
    command: '--address=/.test/127.0.0.1'
    volumes:
      - ~/.iwf-dev/dns:/etc/dnsmasq.d:ro
    ports:
      - "53:53/udp"
    cap_add:
      - NET_ADMIN

networks:
  web:
    external: true

and traefik is not reachable over https://traefik.test/dashboard/ anymore (it works on OrbStack 2.0.1)

sorry i found lots of log entries like this

time="2026-04-20T08:22:59Z" level=error msg="Provider connection error Error response from daemon: client version 1.24 is too old. Minimum supported API version is 1.40, please upgrade your client to a newer version, retrying in 7.211303916s" providerName=docker

did you downgrade something?

which is weird because your client is newer

i think i figured it out. i think the issue is ourselves, because we use an older version of traefik (2.10) and that client seems to be on 1.24 which is why it worked on OrbStack 2.0.1 as this was exactly the min version required

now with orbstack 2.1.0 its API version: 1.54 (minimum version 1.40). if someone can confirm my hypothesis please? i guess we can just close it then

[kdrag0n]

Docker 29 raised the minimum API version to 1.40. Traefik 2.10 is on API 1.24, so it can't talk to the daemon anymore.

The Docker update wasn't optional on our side; older versions had a security issue that's fixed in 29.x. Updating Traefik to a newer version should fix it.
