< bd808> mutante: I'd actually like to see a tin-like box in codfw that got a full sync of /srv/mediawiki-staging that included all the .git/ stuff that we don't send to the rsync-slaves
<bd808> Then we could in theory deploy from codfw if needed
< mutante> bd808: that sounds good to me (having a tin-like box)
Yes, agreed, we did have tasks for all the appservers, but i don't think we had one for a deployment server, equivalent of tin, so i added this.

I'll take a look at this later today. I'm adding the hardware-requests project and claiming this for allocation later.
discussion in ops meeting states this should instead be used as a virtual machine in codfw.
It will need decent resource allocation. The localization update process that runs nightly and the localization cache rebuild step in scap needs good disk io (fstat) performance and multiple cores to complete in a reasonable time. On the virtualized deployment-bastion instance in Labs, the l10nupdate that is part of running scap can take 18-20 minutes to complete because of limited IOPS and cores.

system mira/wmf5818 is assigned for this task. I've linked in task T95436 for the installation and deployment.
