Command Line Help
-----------------

To list available commands, either run ``docker`` with no parameters or execute
``docker help``::

  $ sudo docker
    Usage: docker [OPTIONS] COMMAND [arg...]
      -H=[unix:///var/run/docker.sock]: tcp://host:port to bind/connect to or unix://path/to/socket to use

    A self-sufficient runtime for linux containers.

    ...

.. _cli_attach:

``attach``
----------

::

    Usage: docker attach CONTAINER

    Attach to a running container.

      -nostdin=false: Do not attach stdin
      -sig-proxy=true: Proxify all received signal to the process (even in non-tty mode)

You can detach from the container again (and leave it running) with
``CTRL-c`` (for a quiet exit) or ``CTRL-\`` to get a stacktrace of
the Docker client when it quits.

To stop a container, use ``docker stop``

To kill the container, use ``docker kill``

.. _cli_build:

``build``
---------

::

    Usage: docker build [OPTIONS] PATH | URL | -
    Build a new container image from the source code at PATH
      -t="": Repository name (and optionally a tag) to be applied to the resulting image in case of success.
      -q=false: Suppress verbose build output.
      -no-cache: Do not use the cache when building the image.
      -rm: Remove intermediate containers after a successful build
    When a single Dockerfile is given as URL, then no context is set. When a git repository is set as URL, the repository is used as context

.. _cli_build_examples:

Examples:
~~~~~~~~~

.. code-block:: bash

    sudo docker build .

This will read the ``Dockerfile`` from the current directory. It will
also send any other files and directories found in the current
directory to the ``docker`` daemon.

The contents of this directory would be used by ``ADD`` commands found
within the ``Dockerfile``.  This will send a lot of data to the
``docker`` daemon if the current directory contains a lot of data.  If
the absolute path is provided instead of ``.`` then only the files and
directories required by the ADD commands from the ``Dockerfile`` will be
added to the context and transferred to the ``docker`` daemon.

.. code-block:: bash

   sudo docker build -t vieux/apache:2.0 .

This will build like the previous example, but it will then tag the
resulting image. The repository name will be ``vieux/apache`` and the
tag will be ``2.0``


.. code-block:: bash

    sudo docker build - < Dockerfile

This will read a ``Dockerfile`` from *stdin* without context. Due to
the lack of a context, no contents of any local directory will be sent
to the ``docker`` daemon.  ``ADD`` doesn't work when running in this
mode because the absence of the context provides no source files to
copy to the container.

.. code-block:: bash

    sudo docker build github.com/creack/docker-firefox

This will clone the Github repository and use it as context. The
``Dockerfile`` at the root of the repository is used as
``Dockerfile``.  Note that you can specify an arbitrary git repository
by using the ``git://`` schema.


.. _cli_commit:

``commit``
----------

::

    Usage: docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]

    Create a new image from a container's changes

      -m="": Commit message
      -author="": Author (eg. "John Hannibal Smith <hannibal@a-team.com>"
      -run="": Configuration to be applied when the image is launched with `docker run`.
               (ex: '{"Cmd": ["cat", "/world"], "PortSpecs": ["22"]}')

    Create a new filesystem image from the contents of a tarball

At this time, the URL must start with ``http`` and point to a single
file archive (.tar, .tar.gz, .tgz, .bzip, .tar.xz, .txz) containing a
root filesystem. If you would like to import from a local directory or
archive, you can use the ``-`` parameter to take the data from
standard in.

Examples
~~~~~~~~

Import from a remote location
.............................

This will create a new untagged image.

``$ sudo docker import http://example.com/exampleimage.tgz``

Import from a local file
........................

Import to docker via pipe and standard in

``$ cat exampleimage.tgz | sudo docker import - exampleimagelocal:new``

Import from a local directory
.............................

``$ sudo tar -c . | docker import - exampleimagedir``

Note the ``sudo`` in this example -- you must preserve the ownership
of the files (especially root ownership) during the archiving with
tar. If you are not root (or sudo) when you tar, then the ownerships
might not get preserved.

Examples:
~~~~~~~~~

.. code-block:: bash

    $ docker rm /redis
    /redis


This will remove the container referenced under the link ``/redis``.


.. code-block:: bash

    $ docker rm -link /webapp/redis
    /webapp/redis


This will remove the underlying link between ``/webapp`` and the ``/redis`` containers removing all
network communication.

.. code-block:: bash

    $ docker rm `docker ps -a -q`

      -P=false: Publish all exposed ports to the host interfaces

Examples
--------

.. code-block:: bash

    sudo docker run -cidfile /tmp/docker_test.cid ubuntu echo "test"

This will create a container and print "test" to the console. The
``cidfile`` flag makes docker attempt to create a new file and write the
container ID to it. If the file exists already, docker will return an
error. Docker will close this file when docker run exits.

.. code-block:: bash

   docker run mount -t tmpfs none /var/spool/squid

This will *not* work, because by default, most potentially dangerous
kernel capabilities are dropped; including ``cap_sys_admin`` (which is
required to mount filesystems). However, the ``-privileged`` flag will
allow it to run:

.. code-block:: bash

   docker run -privileged mount -t tmpfs none /var/spool/squid

The ``-privileged`` flag gives *all* capabilities to the container,
and it also lifts all the limitations enforced by the ``device``
cgroup controller. In other words, the container can then do almost
everything that the host can do. This flag exists to allow special
use-cases, like running Docker within Docker.

.. code-block:: bash

   docker  run -w /path/to/dir/ -i -t  ubuntu pwd

The ``-w`` lets the command being executed inside directory given,
here /path/to/dir/. If the path does not exists it is created inside the
container.

.. code-block:: bash

   docker  run  -v `pwd`:`pwd` -w `pwd` -i -t  ubuntu pwd

The ``-v`` flag mounts the current working directory into the container.
The ``-w`` lets the command being executed inside the current
working directory, by changing into the directory to the value
returned by ``pwd``. So this combination executes the command
using the container, but inside the current working directory.

.. code-block:: bash

    docker run -p 127.0.0.1:80:8080 ubuntu bash

This binds port ``8080`` of the container to port ``80`` on 127.0.0.1 of the
host machine. :ref:`port_redirection` explains in detail how to manipulate ports
in Docker.

.. code-block:: bash

    docker run -expose 80 ubuntu bash

This exposes port ``80`` of the container for use within a link without
publishing the port to the host system's interfaces. :ref:`port_redirection`
explains in detail how to manipulate ports in Docker.

.. code-block:: bash

    docker run -name console -t -i ubuntu bash

This will create and run a new container with the container name
being ``console``.

.. code-block:: bash

    docker run -link /redis:redis -name console ubuntu bash

The ``-link`` flag will link the container named ``/redis`` into the
newly created container with the alias ``redis``.  The new container
can access the network and environment of the redis container via
environment variables.  The ``-name`` flag will assign the name ``console``
to the newly created container.

.. code-block:: bash

   docker run -volumes-from 777f7dc92da7,ba8c0c54f0f2:ro -i -t ubuntu pwd

The ``-volumes-from`` flag mounts all the defined volumes from the
refrence containers. Containers can be specified by a comma seperated
list or by repetitions of the ``-volumes-from`` argument. The container
id may be optionally suffixed with ``:ro`` or ``:rw`` to mount the volumes in
read-only or read-write mode, respectively. By default, the volumes are mounted
in the same mode (rw or ro) as the reference container.

     -notrunc=false: Don't truncate output
