Add persistent volumes #2

This is currently fine running via minikube but to go live it needs to have persistent volumes for storing stuff, which so far is:

influxdb data/config
chronograf data/config
kapacitor data/config
telegraf data/config
postgresql data
traefik data

~30gb (5gb for each, even though it seems overkill for traefik) should be fine to start with, as long some sort of monitoring+alerting is set up for when that's no longer enough

This needs clean up for publishing but is mostly done:

Volumes created and attached to VMs via the linode cli
Gluster/Heketi spun up by running gk-deploy.sh from the gluster-kubernetes on one of the nodes in the cluster

The volume creation/attachment code is in the python that needs to be cleaned up and published

vigevenoj commented 6 years ago

Ansible playbooks generate our topology.json, copy it to a node, and use it as input to gk-deploy.

All that's left to do is to either take the output of gk-deploy and scrape it for the heketi address, or use kubectl to do that, and then put that value into storageclass.yaml

Given that https://github.com/heketi/heketi is in "almost maintenance" mode and https://github.com/gluster/gluster-kubernetes is archived; don't use them for storage here. linode-blockstorage-csi looks like the best option going forward and lines up with other supported mechanisms
