The basics
=============
Starting Docker
---------------
If you have used one of the quick install paths', Docker may have been installed with upstart, Ubuntu's
system for starting processes at boot time. You should be able to run ``docker help`` and get output.
If you get ``docker: command not found`` or something like ``/var/lib/docker/repositories: permission denied``
you will need to specify the path to it and manually start it.
.. code-block:: bash
# Run docker in daemon mode
sudo <path to>/docker -d &

Committing (saving) an image
-----------------------------
Save your containers state to a container image, so the state can be re-used.
When you commit your container only the differences between the image the container was created from
and the current state of the container will be stored (as a diff). See which images you already have
using ``docker images``
.. code-block:: bash
# Commit your container to a new named image
docker commit <container_id> <some_name>
# List your containers
docker images
You now have a image state from which you can create new instances.
Committing an image
---------------------
Committing your container to an (named) image is useful because this way it can be re-used. Compare it to creating
a virtual machine image. Except your containers will generally be shorted lived so saving (committing) the state of
it is more important.
The state of a container can be saved at any time by running
::
docker commit <container_id>
However, it is probably more useful to commit it to a specific name
::
docker commit <container_id> <your username>/some_name

Committing containers to named images is not only usefull when committing to the repository. But in order to commit to
the repository it is required to have an image with your namespace.

Notes:
------
- **Docker daemon** The docker daemon is started by ``sudo docker -d``, Vagrant may have started
the Docker daemon for you, but you will need to restart it this way if it was terminated. Otherwise
it may give you ``Couldn't create Tag store: open /var/lib/docker/repositories: permission denied``

Not at this time, Docker currently only runs on Linux, but you can use VirtualBox to run Docker in a virtual machine on your box, and get the best of both worlds. Check out the MacOSX_ and Windows_ intallation guides.

They are complementary. VMs are best used to allocate chunks of hardware resources. Containers operate at the process level, which makes them very lightweight and perfect as a unit of software delivery.
