Helm Chart about gluster-kubernetes HOT 7 OPEN

This is awesome, thanks @hunter. We are trying to get as many things into Kubernetes primitives as possible (daemonsets, configmaps, etc.) - some of that work is happening here #38.

from gluster-kubernetes.

Hi @hunter I have been looking at Helm, but, afaict, there is not step process. It would be great for Heml to support a step process.

It looks like it would be more successful to have a Job which runs gkdeploy.

Also heketi/heketi#622 will make configuration much easier.

from gluster-kubernetes.

I'm not entirely convinced there needs to be step process in Helm.

The main things that are missing from this helm chart are importing the topology and persisting heketi.db. I've not had time to implement but both of those could be handled by init-containers which would also remove the need for a deploy-heketi resource. The downside is that it will only be supported in environments with alpha (1.3) or beta (1.4/1.5) extensions enabled.

Helm also does have install/upgrade hooks. These can trigger one off actions but I don't really see a need to make it helm specific when init-containers exist.

@hunter Init container could work well. This is something @ant31 is also working on.

this is awesome @hunter! i would like to try this with our project: https://github.com/att-comdev/openstack-helm, because I know our users are going to want other storage options (we're currently using Ceph PVC's for Kubernetes). we would love to collaborate with you and the gluster team on this!

from gluster-kubernetes.

Heketi topology could be installed as a post-install or post-upgrade hook in helm:
https://github.com/kubernetes/helm/blob/master/docs/charts_hooks.md

In the future maybe it would also make sense to use node labels for dynamically configure heketi (and create something like etcd-operator), see #46

@hunter How about also introducing an endpoint as a part of helm chart?

from gluster-kubernetes.

Hmm. Probably more appropriate than endpoint is storage class:

apiVersion: storage.k8s.io/v1beta1
kind: StorageClass
metadata:
  name: slow
provisioner: kubernetes.io/glusterfs
parameters:
  resturl: "http://127.0.0.1:8081"
  restauthenabled: "true"
  restuser: "admin"
  secretNamespace: "default"
  secretName: "heketi-secret"
