21:00:33 <openstack> The meeting name has been set to 'scientific_sig'
21:00:54 <oneswig> Apologies, I don't think we have an agenda for today
21:01:01 <oneswig> On the back foot
21:01:02 <martial> time for more Scientific SIG goodness!
21:01:11 <oneswig> Hi martial, afternoon!
21:01:14 <oneswig> #chair martial
21:01:16 <openstack> Current chairs: martial oneswig
21:01:27 <oneswig> So what's new with you?
21:02:11 <martial> not much, slowly accepting that kids will be home for longer ;)
21:02:32 <martial> that ADAC8 sounds interesting
21:02:36 <oneswig> It's blurring into summer holidays here - just a couple of weeks to go
21:03:02 <oneswig> Its an interesting presentation and I'm sure Bill Sparks has put a good deal of thought into it.
21:04:52 <oneswig> Over here I'm having fun with revisiting an old Ansible role we put together for mounting Manila CephFS native shares from within instances.
21:04:54 <martial> although I am not aware of shasta linux
21:05:25 <oneswig> It'll be the new name for Cray's Linux distro, I think.
21:08:45 <oneswig> martial: have you used the Kubernetes cluster api much?
21:09:38 <oneswig> #link Kubernetes Cluster API https://github.com/kubernetes-sigs/cluster-api
21:10:01 <oneswig> Perhaps this is better: https://cluster-api.sigs.k8s.io/
21:10:32 <oneswig> Looks like they want to do to Kubespray what Ceph Orchestrator does for Ceph-Ansible
21:11:12 <b1airo> Actually speaking of k8s, any recommendations for deployment of a small internal hosting cluster? I know about kubespray of course, just wondering if there's anything else worth considering or if it's just that simple?
21:11:15 <martial> interesting
21:11:35 <martial> how small?
21:12:15 <martial> #chair b1airo
21:12:16 <openstack> Current chairs: b1airo martial oneswig
21:12:30 <oneswig> hi b1airo, morning
21:14:13 <b1airo> martial: at this point it'll run a handful of services, none of which really need much in way of scale, so maybe <20 cores, <100GB ram
21:14:56 <b1airo> We're intending to deploy to VMs (across different hosts)
21:16:00 <martial> on top of OpenStack then?
21:16:08 <martial> we do mostly kubespray
21:16:30 <martial> but if you do it on top of OpenStack you can also use TerraForm
21:16:58 <b1airo> Yep. But old Bright OpenStack, so no Magnum there, also think direct API integration is probably more trouble than it is worth considering dynamic scaling is not really needed
21:17:32 <oneswig> kubespray it b1airo.  Job done.
21:17:44 <b1airo> 👍
21:17:51 <martial> or the openstack-k8s-cloud-provider but I have little experience with that one (yet)
21:18:31 <b1airo> Any warnings about network plugins - OpenStack is on OVS
21:19:17 <martial> this looks very similar to what I did about a year ago https://github.com/kubernetes-sigs/kubespray/tree/master/contrib/terraform/openstack
21:21:15 <martial> for a much smaller stack, you can play with https://k3s.io/
21:21:57 <martial> super easy to get a bunch of Jetson Nanos or Raspberry Pi to have your own "kubectl" compatible stack :)
21:25:06 <martial> that cluster-api link looks rather intriguing
21:25:47 <oneswig> martial: ever come across Civo - hosted k3s for dev systems?
21:25:56 <oneswig> #link Civo K3S hosting https://www.civo.com/
21:27:30 <martial> does seem super sweet, but no, never heard of them
21:27:45 <martial> I will confirm the "get k3s up in under 2 minutes" that said
21:28:09 <martial> I have a small stack of Jetson Nano with Ubuntu 18.04 and k3s running
21:28:22 <martial> a "cheap GPU box" :)
21:28:54 <b1airo> If I could use my work card to do that...
21:30:16 <b1airo> Civo looks neat
21:30:31 <martial> Not sure I understand what civo adds to k3s that said
21:30:56 <b1airo> Infra I guess
21:32:52 <b1airo> I'm starting another meeting, will keep a lazy eye out..
21:33:03 <oneswig> later b1airo
21:33:14 <martial> I see https://www.civo.com/learn/civo-kubernetes-quick-start-guide they give you a cluster to play with
21:33:19 <martial> (well "play")
21:33:29 <martial> using k3s to deploy it
21:33:33 <martial> not a crazy udea
21:41:11 <martial> now I wanna try k3s on a small stack :)
21:42:02 <oneswig> Knock yourself out martial - and let me know if it's any good!
21:45:02 <oneswig> Did you attend OpenDev last week?
21:45:45 <martial> no was super swamped by other tasks sadly
21:45:51 <martial> how was it?
21:47:01 <oneswig> It went pretty well I think, like a large PTG fishbowl session.
21:47:43 <oneswig> The sessions are all on youtube but they run at a gentle pace.
21:49:02 <martial> cool
21:49:11 <martial> will have to check the links
21:49:21 <oneswig> The next session is on hardware automation, which is pretty interesting and a little more focused.
21:51:58 <b1airo> Been meaning to check it out after seeing Tim posting about it on twitter
21:58:51 <oneswig> Nearly time, let us know how you get on with your k8s cluster b1airo
22:00:26 <oneswig> OK, thanks guys - until next time
22:00:26 <b1airo> Roger that
