Storage for Containers Using Ceph RBD – Part IV

Shipping containers

Overview

In this article we will look at how to integrate Ceph RBD (Rados Block Device) with Kubernetes and OpenShift. Ceph is of course a scale-out software-defined storage system that provides block, file and object storage. It focuses primarily on cloud-storage use cases. Providing storage for Kubernetes and OpenShift is just one of many use cases that fit very well with Ceph.

Storage for Containers using NetApp SolidFire– Part VI

Shipping containers

Overview

In this article we will look at how you can configure and dynamically provision NetApp SolidFire Storage for containerized applications in a Kubernetes/OpenShift environment. This article is a work from Kapil Arora (Cloud Platform Architect @NetApp).

NetApp recently released an open source project known as Trident, the first external storage provisioner for Kubernetes leveraging on-premises storage.

Trident enables the use of the new storage class concept in Kubernetes, acting as a provisioning controller that watches for PVCs (persistent volume requests) and creates them on-demand.

This means that when a pod requests storage from a storage class that Trident is responsible for, it will provision a volume that meets those requirements and make it available to the pod in real-time.

To learn more  check-out these  Trident videos.

Storage for Containers using Container Native Storage – Part III

Shipping containers

Overview

In this article we will focus on a new area of storage for containers called Container Native Storage. This article is a collaboration between Daniel Messer (Technical Marketing Manager Storage @RedHat) and Keith Tenzer (Sr. Solutions Architect @RedHat).

So What is Container Native Storage?

Essentially container native storage or CNS is a hyper-converged approach to storage and compute in the context of containers. Each container host or node supplies both compute and storage allowing storage to be completely integrated or absorbed by the platform itself. A software-defined storage system running in containers on the platform, consumes disks provided by nodes and provides a cluster-wide storage abstraction layer. The software-defined storage system then provides capabilities such as high-availability, dynamic provisioning and general storage management. This enables DevOps from a storage perspective, allows storage to grow with the container platform and delivers a high level of efficiency.

Storage for Containers using Gluster – Part II

Shipping containers

Overview

This article is a collaboration between Daniel Messer (Technical Marketing Manager Storage @RedHat) and Keith Tenzer (Solutions Architect @RedHat).

Gluster as Container-Ready Storage (CRS)

In this article we will look at one of the first options of storage for containers and how to deploy it. Support for GlusterFS has been in Kubernetes and OpenShift for some time. GlusterFS is a good fit because it is available across all deployment options: bare-metal, virtual, on-premise and public cloud. The recent addition of GlusterFS running in a container will be discussed later in this series.

GlusterFS is a distributed filesystem at heart with a native protocol (GlusterFS) and various other protocols (NFS, SMB,…). For integration with OpenShift, nodes will use the native protocol via FUSE to mount GlusterFS volumes on the node itself and then have them bind-mount’ed into the target containers. OpenShift/Kubernetes has a native provisioner that implements requesting, releasing and (un-)mounting GlusterFS volumes.

Storage for Containers Overview – Part I

Shipping containers

Overview

This is a six part series dedicated to container storage. The article series is a collaboration between Daniel Messer (Technical Marketing Manager Storage @RedHat), Keith Tenzer (Solutions Architect @RedHat) and Kapil Arora (Cloud Platform Architect @NetApp). The focus of this article is an overview on storage for containers. In this article we will focus on laying out fundamentals critical to any container storage discussion. In addition we will go into some details on the various solutions that exist today.
