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

this solution didnt help me

I am installing docker on android. I got docker binaries and extract/install it well. docker –version work correctly. But any other docker command does not work. I execute dockerd and it SEEMS it works but i dont know.
this is the error i got after running docker run hello-world
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

anyway. after lots of search it seems these packages are not installed and I don’t know how to get it. I could get docker binaries via adb shell and root. Also I have Tremux on android.

1- systemctl 2-systemd

after “systemctl status docker” it shows me “systemctl not found”.
I am confused and dont know what is the problem here.

I added the execution path to $PATH
Thanks a lot
