Get started with our K8s Architecture Design and Deployment Workshop and our Cloud-native Migration Services. It must exist in the same namespace as PVCs. Snapshots can be exported as a file. Ceph builds a private cloud system using OpenStack technology, allowing users to mix unstructured and structured data in the same system. You may use Ceph Block Device images with Kubernetes v1.13 and later through ceph-csi, which dynamically provisions RBD images to back Kubernetes volumes and maps these RBD images as block devices (optionally mounting a file system contained within the image) on worker nodes … On-disk files in a container are ephemeral, which presents some problems for non-trivial applications when running in containers. Enjoy peace of mind with Managed Kubernetes … Supported or fully managed from public cloud to on-prem. Other interesting GlusterFS alternatives are DRBD (Free, Open Source), Seaweed FS (Free, Open Source), BeeGFS (Free) and … Familiarity with volumes and persistent volumes is suggested. 6. You can read a comparison between the two here (and followup update of comparison), although keep in mind that the benchmarks are done by someone who is a little biased. One problem is the loss of files when a container crashes. gluster-kubernetes is a project to provide Kubernetes administrators a mechanism to easily deploy GlusterFS as a native storage service onto an existing Kubernetes cluster.

The good news, you can run Ceph on Kubernetes and then use that storage for other Kubernetes resources. These important use cases that GlusterFS was designed to handle are very different from a typical container environment managed by Kubernetes or OpenShift, in which you have a large number of relatively small volumes (10 GB-1TB) that are frequently provisioned and moved as workloads are dynamically and … The most popular alternative is Ceph, which is both free and Open Source.
