SSH into Docker Toolbox

Requirements

You shell must have an SSH client (the ssh command or equivalent).

Manual

Before going to use the automated approach, you should understand how to fetch all required information via the docker-machine command.

Gather all information

1. Get active Toolbox machine name

   host> docker-machine active
   default

2. Print all information

   host> docker-machine -D ssh default
   Host : localhost
   Port : 51701
   User : docker
   Key : .docker\machine\machines\default\id_rsa

Gather specific information

1. Get active Toolbox machine name

   host> docker-machine active
   default

2. Get SSH username (Using machine name default from above)

   host> docker-machine inspect default --format={{.Driver.SSHUser}}
   docker

3. Get SSH public key (Using machine name default from above)

   host> docker-machine inspect default --format={{.Driver.SSHKeyPath}}
   .docker\machine\machines\default\id_rsa

4. Get local SSH port (Using machine name default from above)

   host> docker-machine inspect default --format={{.Driver.SSHPort}}
   51701

5. Get Docker Toolbox IP address (Using machine name default from above)

   host> docker-machine ip default
   192.168.99.100

SSH into Docker Toolbox

Now with the above gathered information you can ssh into Docker Toolbox in two different ways:

1. via local port-forwarded ssh port (automatically forwarded by Docker Toolbox)

   host> ssh -i .docker\machine\machines\default\id_rsa -p 51701 [email protected]

2. via Docker Toolbox IP address

   host> ssh -i .docker\machine\machines\default\id_rsa [email protected]

Automated

Instead of typing all of the above manually each time, you can also create a small bash script to automate this.

1. Create a file ssh-docker.sh and add the following to it:

   #!/bin/bash
   docker_machine_name=$(docker-machine active)
   docker_ssh_user=$(docker-machine inspect $docker_machine_name --format={{.Driver.SSHUser}})
   docker_ssh_key=$(docker-machine inspect $docker_machine_name --format={{.Driver.SSHKeyPath}})
   docker_ssh_port=$(docker-machine inspect $docker_machine_name --format={{.Driver.SSHPort}})
   
   ssh -i $docker_ssh_key -p $docker_ssh_port $docker_ssh_user@localhost

2. Run it:

   host> bash ssh-docker.sh
