It can be installed on any Kubernetes cluster with Helm, with kubectl, or with the Rancher UI. Topologie It looks like it would be more successful to have a Job which runs gkdeploy. In Docker, a volume is simply a directory ondisk or in another Container. However due to some reason, we need to bring down the release (helm del) and re-install it (helm install). I was playing with helm. And again running pvcreate manually fixed the issue. Gluster allows the creation of various types of volumes such as Distributed, Replicated, Striped, Dispersed, and many combinations of these as described in detail here. In clusters that store data on GlusterFS volumes, you may experience an issue where pods fail to mount volumes after restarting the kubelet.The logging of the kubelet will show: transport endpoint is not connected.To prevent this from happening, you can configure your cluster to mount the systemd-run binary in the kubelet container. Soy Oscar Mas y me gustaría enseñaros que es Helm y como montar el almacenamiento para que Helm funcione correctamente.

Following this guide I installed heketi-cli and started to follow the steps: At this point, we have 2 GlusterFS pods and heketi deployer running. For cluster administrators, the preferred method of deploying Heketi on Kubernetes is the gluster-kubernetes project. Lifetimes are not managed and until veryrecently there were only local-disk-backed volumes. 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.
