traefik rootless / docker and portainer ?

[ThierryIT]

Hello,
I have been rebuilding a new Ubuntu server, but this time, the docker and all others dockers and portainer-ce will run in rootless mode (I hope).
It is today working for the Portainer docker only. I cannot build any stack yet, still this error message failed to deploy a stack: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

When checking my Traefik config file and reading your post concerning this special mode, if I understood well, Traefik will run in rootless mode when your proxy will need root to run.

The "rootless" socket PATH is today: /run/user/1000/docker.sock .

My proxy config for Traefik v3.0
