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
|
|
|
|
.. code-block:: bash
|
|
|
|
host> docker-machine active
|
|
default
|
|
|
|
2. Print all information
|
|
|
|
.. code-block:: bash
|
|
|
|
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
|
|
|
|
.. code-block:: bash
|
|
|
|
host> docker-machine active
|
|
default
|
|
|
|
2. Get SSH username (Using machine name ``default`` from above)
|
|
|
|
.. code-block:: bash
|
|
|
|
host> docker-machine inspect default --format={{.Driver.SSHUser}}
|
|
docker
|
|
|
|
3. Get SSH public key (Using machine name ``default`` from above)
|
|
|
|
.. code-block:: bash
|
|
|
|
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)
|
|
|
|
.. code-block:: bash
|
|
|
|
host> docker-machine inspect default --format={{.Driver.SSHPort}}
|
|
51701
|
|
|
|
5. Get Docker Toolbox IP address (Using machine name ``default`` from above)
|
|
|
|
.. code-block:: bash
|
|
|
|
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)
|
|
|
|
.. code-block:: bash
|
|
|
|
host> ssh -i .docker\machine\machines\default\id_rsa -p 51701 docker@127.0.0.1
|
|
|
|
2. via Docker Toolbox IP address
|
|
|
|
.. code-block:: bash
|
|
|
|
host> ssh -i .docker\machine\machines\default\id_rsa docker@192.168.99.100
|
|
|
|
|
|
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:
|
|
|
|
.. code-block:: bash
|
|
:caption: ssh-docker.sh
|
|
|
|
#!/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:
|
|
|
|
.. code-block:: bash
|
|
|
|
host> bash ssh-docker.sh
|
|
|
