Compatible with podman rootless?

[Finch290]

Describe the bug
I'm using the latest version compatible with podman.

Trying to reach my dozzle.domain.com pointing on my dozzle container on my VPS, it shows

"{
"detail": "session was not ready after 1m30s",
"instance": "/api/strategies/blocking?group=dozzle\u0026session_duration=2m\u0026timeout=90s",
"status": 500,
"title": "Internal Server Error",
"type": "https://sablierapp.dev/#/errors?id=internal-error"
}"

Without sablier as a middleware in traefik, going to dozzle.domain.com let me access dozzle. But as soon as i activate the middleware it shows that error. But the thing is, sablier is waking up dozzle and is stopping it. but it doesn't let me access the URL.

Sablier logs :

8:49PM ERR slog-gin@v1.15.1/middleware.go:265 Error #01: Internal Server Error request.time=2025-07-27T20:48:03.829Z request.method=GET request.host=sablier:10000 request.path=/api/strategies/blocking request.query="group=dozzle&session_duration=2m&timeout=1m" request.params=map[] request.route=/api/strategies/blocking request.ip=10.93.6.85 request.referer="" request.length=0 response.time=2025-07-27T20:49:04.395Z response.latency=1m0.566088993s response.status=500 response.length=272 id=22e16e2c-e0a7-47c6-b14a-30ac604d859e

Context

• Sablier version: 1.10.0
• Provider: podman 4.3.1
• Reverse proxy: traefik 3.4.4
• Sablier running inside a container : yes

my traefik dynamic.yml :

    sablier:
      plugin:
        sablier:
          sablierUrl: http://sablier:10000
          group: dozzle
          sessionDuration: 2m
          blocking:
            timeout: 1m

my sablier compose :

services:
  sablier:
    image: sablierapp/sablier:latest
    container_name: sablier
    command:
      - start
      - --provider.name=podman
    environment:
      - TZ=Europe/Paris
      - SABLIER_LOG_LEVEL=debug
    volumes:
      - /run/user/1001/podman/podman.sock:/run/podman/podman.sock:ro
    security_opt:
      - no-new-privileges:true
    networks:
      - proxy

and dozzle compose :

services:
  dozzle:
    image: ghcr.io/amir20/dozzle:latest
    container_name: dozzle
    hostname: "Server"
    networks:
      - proxy
    labels:
      - sablier.enable=true
      - sablier.group=dozzle          
    environment:
      - DOZZLE_HOSTNAME=Server
      - DOCKER_HOST=unix:///var/run/docker.sock
    volumes:
      - /opt/podman/dozzle/data:/data:Z
      - /opt/podman/dozzle/data/users.yml:/data/users.yml:ro,Z
      - /run/user/1001/podman/podman.sock:/var/run/docker.sock:ro
    security_opt:
      - no-new-privileges

Expected behavior
Sablier doesn't let me access my container

Additional context
Traefik, dozzle, sablier are on the same network, they can communicate with each others.

I'm completely lost
Thank you in advance for your help

It should be compatible with podman rootless as long as you expose a socket for podman.

Can you set sablier log level to debug and paste all of the logs? (--logging.level=debug)

Also can you share your Sablier configuration ?

So you dozzle container is properly found, when you request it to start it seems that it cannot be considered started within a minute so it fails.

When you try to access dozzle with the middleware enabled, what is the current status of the dozzle container ? (i.e.: podman ps)

Yes but even if i set timeout: 3m it will fail.

the container is down and reaching the URL wakes up dozzle and it stays up until sablier put it to sleep again

Does dozzle have an healthcheck defined ?

no

I will add some debug logging which should help us investigate, it will be released in 1.10.1, I will release it in a few days!

[acouvreur]

Released v1.10.1 with more debug logging. Enable debug logging and print the result please

@Finch290 do you have any more information ?
