Docker container factory registration failed

[Tilakkumar]

Hi,

I am trying to run cadvisor in docker swarm. Looks like cadvisor is not getting docker details. Please suggest.

http://host:8080/docker/ shows ->Cannot connect to the Docker daemon. Is the docker daemon running on this host?

cadv

Docker version - 17.09.0-ce.

I did try "sudo docker service create" and "sudo usermod -aG docker $USER". Both did not help.

Thanks

Try using a more recent version of cadvisor. Maybe v0.27.3 or v0.28.2
