6 - 01 - Install Docker Machine

Docker Machine enables you to provision multiple remote Docker hosts on various flavors of Linux.
You have an old host for running docker, but this old host is not able to run new Docker application.


You can install Docker and Docker Machine in the old host, and run the Docker Engine locally.
Using Docker Machiner to remote controll other newer hosts to run new Docker application.



1. There are three KVM, and running the ubuntu-16.04.6-desktop-amd64.iso.
But in this lab, it will only use the KVM1.
KVM1 install Docker first. ping KVM2(192.168.122.251) and KVM3(192.168.122.64)

2. In KVM1, install Docker Machine(v0.16.1)

peter@peter-KVM:~$ curl -L https://github.com/docker/machine/releases/download/v0.16.1/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine &&
>     chmod +x /tmp/docker-machine &&
>     sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

3. Verify the Docker Machine version.

peter@peter-KVM:~$ docker-machine -v
docker-machine version 0.16.1, build cce350d7
peter@peter-KVM:~$ 

4. Installing Command Completion

peter@peter-KVM:~$ docker-machine --version
docker-machine version 0.16.1, build cce350d7
peter@peter-KVM:~$ 
peter@peter-KVM:~$ cd /etc/bash_completion.d/
peter@peter-KVM:/etc/bash_completion.d$
peter@peter-KVM:/etc/bash_completion.d$ sudo wget https://raw.githubusercontent.com/docker/machine/v0.16.1/contrib/completion/bash/docker-machine-prompt.bash
peter@peter-KVM:/etc/bash_completion.d$ sudo wget https://raw.githubusercontent.com/docker/machine/v0.16.1/contrib/completion/bash/docker-machine-wrapper.bash
peter@peter-KVM:/etc/bash_completion.d$ sudo wget https://raw.githubusercontent.com/docker/machine/v0.16.1/contrib/completion/bash/docker-machine.bash

5. Add the following this script in the end line of $HOME/.bashrc

peter@peter-KVM:/etc/bash_completion.d$ vi $HOME/.bashrc

PS1='[\u@\h \W$(__docker_machine_ps1)]\$ '

6. logout and login again.
