I have following scenario.

1. Two Machine ( Physical Machine)
2. One is Windows 10 With Docker On Windows Installer and same way ubuntu 18.04 with docker-ce installed.
3. I can run command on individual and that is fine.
4. I want to connect Ubuntu Docker Host from Docker on Windows machine. So Docker CLI on Windows Point to deamon at Ubuntu Host.

You will need to enable docker remote API on Ubuntu Docker Host by adding below settings in daemon.json or your startup script

[root@localhost ~]# cat /etc/docker/daemon.json
{
  "hosts": [ "unix:///var/run/docker.sock", "tcp://0.0.0.0:2376" ]
}

Once you restart docker you can connect to docker host locally by socket file and remotely by listening port (2376). Verify the listening port of docker on Ubuntu

[root@localhost ~]# netstat -ntlp | grep 2376
tcp6       0      0 :::2376                 :::*                    LISTEN      1169/dockerd

Now you can connect to this docker from Windows machine by setting the DOCKER_HOST env variable in Windows like this

PS C:\Users\YellowDog> set DOCKER_HOST=tcp://<Ubuntu-Docker_Host-IP>:2376
PS C:\Users\YellowDog> docker ps

It will list docker containers running on Ubuntu Docker Host
