15:00 → 15:15 Roundtable

• CentOS 8/CentOS Stream
• Interest in Podman 2 backport to C7?

Present: Steven, Ignacio, Denis, Elisabetta, Pablo

___________________________________________

 

Ignacio: Centos 8. Working on a creating a linux committee. Some of the people from this forum have already been added

Ignacio: forwarded meeting from the accelerators about backporting Podman to centos 6 (email attached at the bottom of this minutes

Steven: it's probably wise to bring that. 

Ignacio asked for a list of features that want to be backported. 

Ignacio: There is also the issue with elasticsearch changing license

Pablo: That will affect only new versions of elastic, and we are checking how to move to opendistro

 

Steven: Little has happened. Few machines  turned on.  Some cables were unplugged. Pugging them back in solved the issue

Steven: are there any part of eos ready to be checked with token authentication? In the USA they are pushing to remove things like grid-url-copy by the end of this year. We have already a token generator. *Steven will create a snow ticket and Ignacio/Pablo will follo

Denis: Moving data from half of the local instance to prepare the replacement. It should finish in 7 days.

Steven: I'd be interested in how eos was setup. We are asking np04 to move to fts3

Elisabetta: Nothing to add

 

Next meeting: 4th of march

Dear all, 
In order to provide a more dynamic environment for some of the application
running on their systems, BE has been investigating using Podman. Such a
container approach would allow for example the accelerator sector to upgrade
WinCC OA regardless of the underlying system (or to run older WinCC OA on
newer operating systems).

The recent change of support in CentOS 8, and the related uncertainty, forced
them to keep using CentOS 7 on some systems (the original project was to use
CentOS 8). Unfortunately, CentOS 7 comes with Podman 1.6 only, which is
missing several features compared to the version 2 of Podman available on
CentOS 8.

In order to continue this project, and to be able to have a transparent
underlying OS update in the future, BE would be interested in back-porting
Podman 2 onto CentOS 7. While they are ready to rebuild it themselves using
CERN tools (koji), they would like to learn if others could be interested in
such a project and if this is the case if the IT department could then
maintain this backport, potentially as a shared responsibility with BE, to
have a more central and responsive solution.

Are you aware if any of the community you are coordinating with would be
interested in this? I know that WLCG has been pushing singularity more in the
past, but Podman is directly supported by RedHat AFAIU.

Thanks in advance,
Vincent
