The work was surprisingly easy. We have a Dockerfile of about 15 lines that
does a a setup of xCAT inside a container. In the initialization we setup a
default table configuration. Directories that contain state are exported as
docker volumes. For process management we use supervisord. For image
generation we inject iso files into the container at start time. Then on
our login node we install the xCAT client package and we are done.
We have tested by running Docker with the guest host's network stack.
The details can be found https://github.com/clustervision/trinity/, notably
in the ha-xcat folder.

At my company we started work to run an xCAT server from inside docker
container. There are still various issues and workarounds (e.g. image
generation does not work as we want it), but the main functionality of
node
discovery and management is functional.
For us running xCAT inside Docker has several advantages:
1. Pluggability. We have various management tools for configuration,
monitoring, starting, stopping and failover that work on generic
containers.
2. Productivity. Another is that we install small clusters on a very
regular basis. The slight time advantage over manual installation is
actually important to us.
3. Flexibility. We can use a single xCAT docker image for each customer
environment we encounter (as long as it supports docker).
If the xCAT project decides to follow up on this requirement, we are
willing to contribute or share our efforts so far.

The issue is not yet resolved, the installation process is stuck when
installing xCAT-2.9-snap201412080202.x86_64.
The only way to stop it is to hit Ctrl + C, once I've done that I got the
following message:
^CError in POSTIN scriptlet in rpm package
xCAT-2.9-snap201412080202.x86_64
Generating new node hostkeys...

Added updates to the /root/.ssh/config file.
Copied /root/.ssh/id_rsa.pub
to /install/postscripts/_ssh/authorized_keys.
error: %post(xCAT-2.9-snap201412080202.x86_64) scriptlet failed, signal 2
The OS I'm using is CentOS 6.6 with the stock kernel.
Thank you,
Dennis.

Hans,
Thanks for your information.
And yes, xCAT will support the dockerized xCAT. Could you send out the
detail of how do you dockerize the xCAT in your scenario?
Thanks
