Best to talk to your local HPC system admins. Most the of the HPC
services I'm familiar with are testing Docker, but I'm not aware of
any who have let it loose on users just yet.
There is a presentation on using Docker on DoE machines in the US:

The big HPC vendors are working container support into their systems.
