for Docker Machine, the termMachineis the host that runs the Docker daemon. "Create machine" refers to installing and deploying Docker on host. Execute Firstdocker-machine lsTake a look at the current machine

As we expected, there is no machine at the moment. Next we create the first machine host1-192.168.56.104.

Create machine requires the ability to log on to a remote host without a password, so you need to copy SSH key to 192.168.56.104 with the following command

Ssh-copy-id 192.168.56.104  

Everything's ready. Execute docker-machine create command Create host1

docker-machine Create--driver generic--generic-ip-address=192.168.56.104 host1

--generic-ip-address   Specifies the IP of the target system and is named   host1 . The command execution procedure is as follows

① Login to the remote host via SSH.
② install Docker.
③ Copy Certificate.
④ Configure Docker daemon.
⑤ start Docker.

re-executes   docker-machine ls

Can already see the host1. We can log in to host1 to see the specific configuration/etc/systemd/system/docker.service of the Docker daemon.

2. -H tcp://0.0.0.0:2376 make Docker daemon accept remote connections.

4. --tls* Enable secure authentication and encryption for remote connections.

And we also see that hostname has been set tohost1

Create host2 using the same method

docker-machine Create--driver generic--generic-ip-address=192.168.56.105 host2

after successful creation   docker-machine ls   you can see that both host1 and Host2 are ready
