Kernel Requirements
|
|
===================
|
|
|
|
If you want to have a full working CRUX+Docker system you will need to
|
|
rebuild your kernel various networking, cgroups and optional lvm options
|
|
|
|
You may check your kernel configuration by running:
|
|
|
|
::
|
|
|
|
./check-config.sh /usr/src/linux/.config
|
|
|
|
|
|
Execution Engines
|
|
=================
|
|
|
|
As of Docker 0.9+ execution engines are pluggable and as such Docker
|
|
no longer depends on lxc.
|
|
|
|
The new default execution driver is now an internal ``libcontainer``
|
|
driver that replaces the need for lxc.
|
|
|
|
Please see the `Docker Documentation <http://docs.docker.io>`_
|
|
if you want to use a different execution engine other then the default.
|
|
|
|
|
|
Storage Backends
|
|
================
|
|
|
|
Docker comes with three main Storage Backends:
|
|
|
|
- AUFS (*requires AUFS kernel/patches*)
|
|
- devmapper
|
|
- btrfs
|
|
|
|
It is recommended you use the devmapper or btrfs backend (Default: devmapper).
|
|
|
|
To use the ``btrfs`` backend edit ``/etc/docker.conf``
|
|
and modify the ``DOCKER_OPTS`` with:
|
|
|
|
::
|
|
|
|
DOCKER_OPTS="-s btrfs"
|
|
|
|
.. note:: As of Docker 0.10.x the ``btrfs`` storage backend is now
|
|
considered stable and has been promoted to an officially
|
|
supported storage backend.
|
|
|
|
|
|
Docker Client
|
|
=============
|
|
|
|
Add yourself to the ``docker`` group if you wish to access
|
|
the Docker daemon on localhost via UNIX Socket.
