Docker 1.10.3 running on ReadyNASOS 6.5.0-T338 (Beta 2)

Hey guys,

 

Just had to shout this out, as I'm kinda excited at the possibilities.  Managed to get Docker running on my VirtualBox ReadyNAS running OS 6.5.0 last night, and it didn't take nearly as much work as I had expected.  Needs some kernel config adjustments, but things are so very close with this latest kernel the Netgear guys have given us.

Netgear guys - is there any possibility these additional kernel configs I've detailed below could make it into a beta at some stage?  Most are CGROUP related, which I think are a good idea to include anyhow (system.d), and some are able to be modularized, so people can load them if they want them.

Why is this good?  Because with this, docker lets us run a personal cloud on our ReadyNAS devices.  It's like running VirtualBox, but with much less virtualization (e.g. less CPU overhead, less memory).  More details here: https://www.docker.com/.

Other than Kernel changes, only other change I had to make was running init-system-helpers from wheezy-backports - I've not noticed any issue with this so far on the virt server, but there may be something I've missed.

 

Some caps:

Diff if you're interested - this is the changes required for Kernel 4.1.19.x86_64.1, which is part of the latest ReadyNASOS 6.5.0-T338 (Beta 2)

Nice work. You might want to suggest Docker support in the Ideas Exchange if it is not already mentioned there.
