kfox1111amrith: around?16:46
amrithkfox1111, hello16:48
kfox1111hey. :)16:48
kfox1111just bumped into something interesting.16:48
kfox1111https://coreos.com/blog/introducing-operators.html16:48
kfox1111would be really interesting for trove I think to provide something like that.16:49
kfox1111and here's an exapmle one: https://github.com/coreos/etcd-operator16:49
amrithkfox1111, what's the problem that this would be solving, what capability would it provide to an end user?16:50
kfox1111its basically what trove is providing to openstack, but on k8s instead of nova.16:50
kfox1111and the trove api could map on top of that I think.16:51
kfox1111the great thing about it, is it leverages k8s's abilities to not need guest agents.16:51
amrithinteresting, so how would this operator (for example) do something like take a backup?16:52
amrithor is that outside of the scope of the operator?16:53
kfox1111either start a new k8s job for it 'kubectl create job ....' or kubectl exec <existing container> mysqlbackup ....16:53
amrithand who would be the keeper of this database specific knowledge? currently that's the guestagent16:53
kfox1111the operator would have the logic I think.16:54
amrithhmm, operators (from this description) appear to be mechanisms to ensure that a cluster of nodes remains at some predetermined configuration (cardinality, ...)16:55
kfox1111I think the operator basically is similar to the superconductor idea from before.16:55
kfox1111it just drives k8s to ensure if specific order of operations are needed (fix mariadb cluster) or specific additional actions (take database backup) there's a surface to expose those.16:55
amrithcool, are you proposing that you'll work on this (suggested answer: yes)16:56
kfox1111I may be working on bits of it for kolla-kubernetes,16:57
kfox1111as I need a way to deploy mariadb nicely.16:57
amrithtrove does that already but you'll say you want it in a container, yes?16:58
kfox1111if its reusable though, it could enter the trove umbrella.16:58
kfox1111need it in a container.16:58
kfox1111we're deploying openstack using k8s.16:58
kfox1111nova needs a db/trove needs a db.16:58
kfox1111cant' use trove to deploy nova or trove.16:58
kfox1111unless you already have a nova/trove.16:59
kfox1111the idea though, is k8s is already assumed to be there in kolla-kubernetes.16:59
kfox1111so if an trove-operator for db would exist, it would be deployed as a normal container, then it would enhance k8s to be able to easily deploy mariadb clusters,17:00
kfox1111then would use that to deploy the cloud db's.17:01
kfox1111we could then deploy a user facing trove, as is, or better would be simply to have a way for trove api to target that underlying k8s operator.17:01
kfox1111then you could deploy db's in k8s instead of in nova.17:01
amrithkfox1111, would be great to see a presentation about this use-case; maybe at summit in boston.17:04
amrithor if you are blogging abotu this, please share a link17:04
kfox1111you going to go to the ptg?17:08
kfox1111I think it will be more likely I'll be at the ptg then the summit.17:08
*** gcb has quit IRC17:08
kfox1111the kolla-kubernetes project is talking about it, and will probably be making a prototype. I'll forward you what I can on the topic once the poc starts/we have a spec.17:08
