I am trying to setup Kubernetes with Gluster using Heketi. Other open source file systems like GlusterFS include Ceph, OpenStack Swift, Lustre, OpenAFS, HDFS etc. The good news, you can run Ceph on Kubernetes and then use that storage for other Kubernetes resources. The kubelet restarts the container but with a clean state. Get started with our K8s Architecture Design and Deployment Workshop and our Cloud-native Migration Services. To learn more about operators, a few weeks ago I wrote about Elasticsearch operator and how it works , so you … Both use the xfs filesystem under the covers to store data … This website uses cookies and other tracking technology to analyse traffic, personalise ads and learn how we can improve the experience for our visitors and customers.

I spent last two days installing GlusterFS storage on top of my Kubernetes. Since both GlusterFS and Ceph belong to RedHat now, I have to wonder … Here's a storage use case made to scale. On-disk files in a container are ephemeral, which presents some problems for non-trivial applications when running in containers. GlusterFS and Ceph are two distributed persistent storage systems. … Ceph and GlusterFS are both good choices, but their ideal applications are subtly different. The real surprise was the last test, where GlusterFS beat Ceph on deletions. It doesn’t have off site backups though, so you need to use something with Velero/Restic which does file-level backups instead of backing up point-in-time snapshots.
