Act_Runner not starting on Raspberry Pi4

[Dennis-Do]

Description

Hello,

I have some containers running in Docker on a Raspberry Pi4. Everything works fine also Gitea. For some reason act_runner is not.

I used the docker compose file from here: https://gitea.com/gitea/act_runner/src/branch/main/examples/docker-compose

I tried it both on Windows with Docker Desktop and on the Pi. On Windows it is starting.

Here are the last Log Messages:

time="2025-07-20T17:03:59.875263048Z" level=info msg="Initializing buildkit" time="2025-07-20T17:03:59.989522131Z" level=info msg="Completed buildkit initialization" time="2025-07-20T17:03:59.993216840Z" level=info msg="Daemon has completed initialization" time="2025-07-20T17:03:59.993315967Z" level=info msg="API listen on [::]:2376" time="2025-07-20T17:03:59.993341722Z" level=info msg="API listen on /var/run/user/1000/docker.sock" time="2025-07-20T17:04:00Z" level=info msg="Starting runner daemon" time="2025-07-20T17:04:00Z" level=info msg="runner: runner_dind_rootless_win_v1, with version: v0.2.12, with labels: [ubuntu-latest ubuntu-22.04 ubuntu-20.04], declare successfully"

On the Raspberry Pi the daemon is not starting and it ends with the sock log:

time="2025-07-20T13:43:43.193443711Z" level=info msg="Initializing buildkit" time="2025-07-20T13:43:43.254762644Z" level=info msg="Completed buildkit initialization" time="2025-07-20T13:43:43.274933256Z" level=info msg="Daemon has completed initialization" time="2025-07-20T13:43:43.275098401Z" level=info msg="API listen on [::]:2376" time="2025-07-20T13:43:43.275102605Z" level=info msg="API listen on /var/run/user/1000/docker.sock"

Docker Engine is the same: 28.3.2
