This repository contains the files needed to build RPMs for the dependencies of Docker on Red Hat Enterprise Linux 6 and derivatives like CentOS and Scientific Linux. The kernel spec file is based on the kernel-ml package from ELRepo but adds aufs support. The lxc spec file is copied from Fedora.
Before building the packages, be sure to install fedora-packager and add yourself to the mock group.
You can build the packages with the following commands. Note that building the kernel can take a long time, maybe even hours. If you want to build these for Fedora instead of RHEL, when running mock you should replace epel-6-x86_64 with fedora-19-x86_64. Also, you can skip building the lxc rpm because it already exists in Fedora's repository.
# build docker rpm
spectool -g -C lxc-docker lxc-docker/lxc-docker.spec
mock -r epel-6-x86_64 --buildsrpm --spec lxc-docker/lxc-docker.spec --sources lxc-docker --resultdir output
mock -r epel-6-x86_64 --rebuild --resultdir output output/lxc-docker-0.6.3-2.el6.src.rpm
# build lxc rpm
spectool -g -C lxc lxc/lxc.spec
mock -r epel-6-x86_64 --buildsrpm --spec lxc/lxc.spec --sources lxc --resultdir output
mock -r epel-6-x86_64 --rebuild --resultdir output output/lxc-0.8.0-3.el6.src.rpm
# build kernel rpm
spectool -g -C kernel-ml-aufs kernel-ml-aufs/kernel-ml-aufs-3.10.spec
git clone git://git.code.sf.net/p/aufs/aufs3-standalone -b aufs3.10
pushd aufs3-standalone
git archive aufs3.10 > ../kernel-ml-aufs/aufs3-standalone.tar
popd
mock -r epel-6-x86_64 --buildsrpm --spec kernel-ml-aufs/kernel-ml-aufs-3.10.spec --sources kernel-ml-aufs --resultdir output
mock -r epel-6-x86_64 --rebuild --resultdir output output/kernel-ml-aufs-3.10.11-1.el6.src.rpm
The resulting RPMs will be placed in a directory named output. You can install them with
cd output
yum localinstall --nogpgcheck kernel-ml-aufs-3.10.11-1.el6.x86_64.rpm lxc-0.8.0-3.el6.x86_64.rpm lxc-libs-0.8.0-3.el6.x86_64.rpm lxc-docker-0.6.3-2.el6.x86_64.rpm
In order to use docker, you'll need to configure the cgroup filesystem and reboot into your new kernel. Add the line
none /sys/fs/cgroup cgroup defaults 0 0
to /etc/fstab. Reboot and choose the 3.10 kernel from your GRUB menu (or edit /boot/grub/grub.conf and change your default kernel).
The docker daemon should have started automatically; this can be controlled by via initctl. To give a non-root user permission to use docker, add them to the docker group.
