This feature adds Juju provisioning to the kube-up script. It currently
parses out the pre-requisits on debian/ubuntu based systems and installs
them if they are missing.
From there we followed the integration path that was found in the
libvirt-coreos path, implementing the methods found in the boilerplate
and calling juju service calls. There are a few "arbitrary sleeps" in
the code to allow the cloud provider to settle and properly deploy.
These are work-around cases from the script executing faster than juju
was able to communicate from the state server to subsequent nodes. I
left comments inline at these points.
To exercise this:
export KUBERNETES_PROVIDER=juju
cluster/kube-up.sh
It will spin up a ref arch with 1 Kubernetes Master, 2 minions, and run
the cluster validation checks against the deployment. Bridging the gap
between the juju specific bits and the upstream recommended guides for
getting started with Juju.
To note, if you do not have a "current environment" set in Juju, it will
spin up the quickstart integration wizard in interactive mode, allowing
you to configure juju, and add the proper provider/use it. Otherwise it
assumes you're in the provider you wish to use, and will deploy there.
libvirt-coreos is a cluster provider for kubernetes that starts local VMs and
runs kubernetes on it.
Its goal is to provide a multi-machines environment to develop and test kubernetes.
The purpose is mostly the same as the vagrant provider but with a big focus on
efficiency. The vagrant cluster takes a long time to boot and consumes a huge
amount of disk space. libvirt-coreos aims at being cheaper. As a consequence,
libvirt-coreos allows to start bigger clusters with more minions than vagrant.
What I really want is
https://github.com/GoogleCloudPlatform/kubernetes/issues/2953, but
haven't had a chance to code that yet. Maybe it's time. (Then I'd
remove the provider-specific test and just say "is it > 0.7.2, or does
it claim to be capable of something from the future?" The latter
covers the HEAD server case .. though just bumping the server version
immediately after release might also accomplish that, too.)
