Kernel Requirements
|
||||
===================
|
||||
|
||||
|
||||
If you want to have a full working CRUX+Docker system you will need to rebuild your kernel with the following options enabled:
|
||||
|
||||
Networking:
|
||||
|
||||
- CONFIG_BRIDGE
|
||||
- CONFIG_NETFILTER_XT_MATCH_ADDRTYPE
|
||||
- CONFIG_NF_NAT
|
||||
- CONFIG_NF_NAT_IPV4
|
||||
- CONFIG_NF_NAT_NEEDED
|
||||
|
||||
LVM:
|
||||
|
||||
- CONFIG_BLK_DEV_DM
|
||||
- CONFIG_DM_THIN_PROVISIONING
|
||||
- CONFIG_EXT4_FS
|
||||
|
||||
Namespaces:
|
||||
- CONFIG_NAMESPACES
|
||||
- CONFIG_UTS_NS
|
||||
- CONFIG_IPC_NS
|
||||
- CONFIG_UID_NS
|
||||
- CONFIG_PID_NS
|
||||
- CONFIG_NET_NS
|
||||
|
||||
Cgroups:
|
||||
|
||||
- CONFIG_CGROUPS
|
||||
|
||||
Cgroups Controllers (*optional but highly recommended*):
|
||||
|
||||
- CONFIG_CGROUP_CPUACCT
|
||||
- CONFIG_BLK_CGROUP
|
||||
- CONFIG_MEMCG
|
||||
- CONFIG_MEMCG_SWAP
|
||||
|
||||
You may check your kernel configuration by running the provided ``test_kernel_config.sh`` script against your kernel configuration:
|
||||
|
||||
::
|
||||
|
||||
./test_kernel_config.sh /usr/src/linux/.config
|
||||
|
||||
|
||||
Other Requirements
|
||||
==================
|
||||
|
||||
|
||||
You **must** have the following ``cgroup`` mount point mounted:
|
||||
|
||||
::
|
||||
|
||||
none /cgroup cgroup defaults 0 0
|
||||
|
||||
|
||||
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"
|
||||
|
||||
|
||||
Docker Client
|
||||
=============
|
||||
|
||||
The provided Docker rc script changes the group ownership of the ``/var/run/socker.sock`` UNIX Socket to ``docker``.
|
||||
|
||||
Add yourself to this group if you wish to access the Docker daemon on localhost via UNIX Socker.
