I'm running a GitHub self hosted action runner which uses the docker cli but the host I am running it on is using containerd as the runtime. docker is installed, except there is no active /var/run/docker.sock. How can I fix this so GitHub action runners work?

pi@kube-master:~ $ sudo find / -name "docker.sock"

pi@kube-master:~ $ sudo find / -name "containerd.sock"
/run/containerd/containerd.sock

pi@kube-master:~ $ docker info
Client: Docker Engine - Community
 Version:    25.0.3
 Context:    default

 Plugins:
  buildx: Docker Buildx (Docker Inc.)

  compose: Docker Compose (Docker Inc.)

    Path:     /usr/libexec/docker/cli-plugins/docker-compose

Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Indeed, when containerd was installed and upgraded the docker systemd service was disabled.

Simply doing sudo systemctl enable --now docker fixed the issue.
