Hey y'all,
Just wanted to give an updated on the work around tripleo+kubernetes.
This is
still far in the future but as we move tripleo to containers using
docker-cmd,
we're also working on the final goal, which is to have it run these
containers
on kubernetes.
One of the first steps is to have TripleO install Kubernetes in the
overcloud
nodes and I've moved forward with this work:
https://review.openstack.org/#/c/471759/
The patch depends on the `ceph-ansible` work and it uses the
mistral-ansible
action to deploy kubernetes by leveraging kargo. As it is, the patch
doesn't
quite work as it requires some files to be in some places (ssh keys) and a
couple of other things. None of these "things" are blockers as in they
can be
solved by just sending some patches here and there.
I thought I'd send this out as an update and to request some early
feedback on
the direction of this patch. The patch, of course, works in my local
environment
;)
Note that Kubespray (former Kargo) now supports the kubeadm tool
natively [0]. This speeds up a cluster bootstrapping from an average
25-30 min to a 9 or so. I believe this makes Kubespray a viable option
for upstream development of OpenStack overclouds managed by K8s.
Especially, bearing in mind the #deployment-time effort and all the hard
work work done by tripleo and infra teams in order to shorten the CI
jobs time.
I tried deploying with kubeadm_enable yesterday and no luck yet on
CentOS, but i do want to get back to this as the speed up sounds
promising :)
AIO kubernetes deployment the non-kubeadm way seemed to work fine
(Flavio's patch above with a workaround for [2] and a small Kubespray
fix [3]).

By the way, here is a package review [1] for adding a kubespray-ansible
library, just ansible roles and playbooks, to RDO. I'd appreciate some
help with moving this forward, like choosing another place to host the
package, it got stuck a little bit.
