Centos added the ARM 7 build to their release train.
To download the Centos 7 minimal image for Raspberry Pi 2 go to
and scroll down to the 'AltArch Releases' and select the armhfp (Arm32) for RaspberryPi2.
On my OSX box I issue:
sudo dd bs=1m if=CentOS-Userland-7-armv7hl-Minimal-1511-RaspberryPi2.img of=/dev/disk2
Double check that your SD Card reader is at /dev/disk2 or you’ll be sorry..
I had some trouble finding the default login credentials but I finally found the documentation here:
with default creds
Use the entire SD Card
By default the partition uses only 2GB. To make enlarge it use
touch /.rootfs-repartition systemctl reboot
Sadly the Docker rpm is not available yet.
