As of 2013/11/26

  • Docker 0.7 has been released and supports devicemapper thin provisioning as an alternative to aufs
  • Docker has been packaged in Fedora and EPEL

Thus the work in this repository is no longer necessary.

This repository contains the files needed to build RPMs for the dependencies of Docker released before 0.7 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-0.6.7-1.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 9929e444955f467073ebedf254a9ac0f7a5df1c5 > ../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-0.6.7-1.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.
