It’s taken a lot longer than expected, but the Open Source University’s promised offer of servers has arrived.
We have an Openstack tenant with:
Servers
CPUs
RAM(Gb)
0-10
0-20
0-50
This would give us 5 servers at 4 CPU / 8Gb RAM. Does that sound good? I’d like to reserve 2 for infra use (new Puppetmaster, and a machine for me to run metrics stuff on), but that would potentially free up some Rackspace budget.
Works for me. That leaves one box at the same spec, right? I’ll take that for metrics and suchlike. I assume we’ll migrate the puppetmaster to a new Rackspace host using the freed capacity?
So we will net 2 slaves in the end if my math is right?
Yes.
How many executors did you set the new ones to? 4?
Yes, 4, these are even a bit faster than the rackspace ones, so it shouldn’t be a problem.
Are the OSU slaves considered “fast” and labeled as such?
Yes.
Assuming these got configured as CentOS 7 slaves?
Exactly, that’s the standard setup. Theoretically some recent Debian/Ubuntu would also be possible, but at least in the last years only CentOS 7 was used, so that would probably need some work.
