Docker Machine Multi-host management

We must be more host in the production process, so I use the Docker-machine management tools to achieve the management of Docker on multiple hosts.

1, installation Docker-machine
setting environment variables;
base=https://github.com/docker/machine/releases/download/v0.14.0
Download
Curl-l $base/docker-machine-$ (uname-s)-$ (uname-m) >/tmp/docker-machine
Setting environment variables
sudo install/tmp/docker-machine/usr/local/bin/docker-machine
At this point, you can execute Docer-machine related instructions to verify success
[Email protected] ~]# Docker-machine--version
Docker-machine version 0.14.0, build 89b8332

2. Add Host
1, set no password login
2. Add Host
[Email protected] ~]# docker-machine create--driver generic--generic-ip-address=192.168.1.39 docker

We're going to add ourselves in.
Now look at the action that executes this command
[Email protected] ~]# Ps-ef|grep Yum

Root 13572 13502 0 20:45 pts/5 00:00:00 grep--color=auto Yum
After executing this command, install Dicker and other plugins in the upgrade

Verify that the addition is complete
