For the record, the Nebraska Tier 2 has beaten us in getting Docker worker nodes into production at a large scale:

I intend to write some simple instructions (including the Dockerfile for the image) but haven't gotten around to it yet. Will try to this in the next few weeks.
Regards,
Andrew.

Hi,
If Andrew's docker method [1] is easy to replicate across (HTCondor) sites, then this could be an easy way to move early to Centos 7.
If instructions are provided, I would definitely give that a go this year.
Cheers,
Luke

Dear all,
as you know there is some work going on in ATLAS to be ready for sites that request it to move to CentOS7 if they need to. There is no pressure or deadline to do a mass upgrade like we did for SL6. The statement from ATLAS is still "not until LS2" (2018) but since most production applications have demonstrated to work in compatibility mode and the native application are now actively being worked on that stance can be softened. Analysis doesn't work yet though I expect this problem to go away with the native releases.
It would be useful to know how many sites will have to move, in the next 6 months to 1 year. ECDF has to move now and is acting as a guinea pig. Lancaster said a queue will be setup before Xmas. Others?
cheers
