All these are shell commands.

docker-machine env to get the current default docker-machine configuration

eval $(docker-machine env) to get the current docker-machine configuration and set the current shell environment up to use this docker-machine with .

If your shell is set up to use a proxy, you can specify the --no-proxy option in order to bypass the proxy when connecting to your docker-machine: eval $(docker-machine env --no-proxy)

If you have multiple docker-machines, you can specify the machine name as argument: eval $(docker-machine env --no-proxy machinename)

All these are shell commands

• If you need to log onto a running docker-machine directly, you can do that:

docker-machine ssh to ssh into the default docker-machine

docker-machine ssh machinename to ssh into a non-default docker-machine

• If you just want to run a single command, you can do so. To run uptime on the default docker-machine to see how long it's been running for, run docker-machine ssh default uptime

Using docker-machine is the best method to install Docker on a machine. It will automatically apply the best security settings available, including generating a unique pair of SSL certificates for mutual authentication and SSH keys.

To create a local machine using Virtualbox:

docker-machine create --driver virtualbox docker-host-1

To install Docker on an existing machine, use the generic driver:

docker-machine -D create -d generic --generic-ip-address 1.2.3.4 docker-host-2

The --driver option tells docker how to create the machine. For a list of supported drivers, see:

• officially supported

• third party

Listing docker-machines will return the state, address and version of Docker of each docker machines.

 docker-machine ls

Will print something like:

NAME             ACTIVE   DRIVER    STATE     URL                          SWARM   DOCKER    ERRORS
docker-machine-1 -        ovh       Running   tcp://1.2.3.4:2376                   v1.11.2   
docker-machine-2 -        generic   Running   tcp://1.2.3.5:2376                   v1.11.2   

To list running machines:

docker-machine ls --filter state=running

To list error machines:

docker-machine ls --filter state=

To list machines who's name starts with 'side-project-', use Golang filter:

docker-machine ls --filter name="^side-project-"

To get only the list of machine's URLs:

docker-machine ls --format '{{ .URL }}'

See https://docs.docker.com/machine/reference/ls/ for the full command reference.

Upgrading a docker machine implies a downtime and may require planing. To upgrade a docker machine, run:

docker-machine upgrade docker-machine-name

This command does not have options

To get the IP address of a docker machine, you can do that with this command :

docker-machine ip machine-name
