1 Kernel Requirements
2 ===================
3
4 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
5
6 Please review the provided ``test_kernel_config.sh`` shell script carefully and use this to test your kernel configuration. This README does not document
7 what these specific options are to vaoid duplication. They are listed instead in ``test_kernel_config.sh``.
8
9 You may check your kernel configuration by running:
10
11 ::
12
13 ./test_kernel_config.sh /usr/src/linux/.config
14
15
16 Execution Engines
17 =================
18
19 As of Docker 0.9+ execution engines are pluggable and as such Docker no longer depends on lxc.
20 The new default execution driver is now an internal ``libcontainer`` driver that replaces the need for lxc.
21
22 Please see the `Docker Documentation <http://docs.docker.io>`_ if you want to use a different execution engine other then the default.
23
24
25 Storage Backends
26 ================
27
28 Docker comes with three main Storage Backends:
29
30 - AUFS (*requires AUFS kernel/patches*)
31 - devmapper
32 - btrfs
33
34 It is recommended you use the devmapper or btrfs backend (Default: devmapper).
35
36 To use the ``btrfs`` backend edit ``/etc/docker.conf`` and modify the ``DOCKER_OPTS`` with:
37
38 ::
39
40 DOCKER_OPTS="-s btrfs"
41
42
43 Docker Client
44 =============
45
46 Add yourself to the ``docker`` group if you wish to access the Docker daemon on localhost via UNIX Socker.
