When you’re studying Kubernetes, one of the first things you learn is that it won’t handle any storage requests for your applications when deploying a new cluster by default. This is because K8s was initially designed only for stateless apps; thus, storage was considered to be an add-on. This was such a common problem that

by Peter Fray (Platform9) and Alessandro Catale (Comfone) There are plenty of articles describing how to setup MongoDB with a Kubernetes operator. However, is Kubernetes a viable solution for running high-performance MongoDB use cases? In this blog, we will describe a real-world application performance test that 200 million MongoDB document inserts and reads per hour

In this article, you will learn how to set up OpenEBS on Kubernetes clusters, as a storage solution for your deployment. OpenEBS is one of the leading open-source projects for cloud-native storage on Kubernetes. OpenEBS adopts the Container Attached Storage (CAS) approach, where each workload is provided with a dedicated storage controller. OpenEBS provides granular

One of the benefits of moving to Kubernetes is that your applications can run in a highly scalable environment. You can add additional pods quickly if you suddenly need more capacity, and then get rid of them when you don’t need them anymore. But what if you are running a stateful application? When you terminate

In the previous article, we deep-dived into the constructs of Kubernetes storage, and what the different types of storage are good for. We discussed dynamic provisioning, StorageClasses, and CSI external storage. In this article, we set up a simple, private sandbox – using minikube – where we can observe and hack on the inner-workings of

Storage in Kubernetes can really frustrate customers and newcomers to the blossoming cloud-native universe. In countless customer experiences – I can honestly say that majority of customer questions and issues around Kubernetes storage are often rather elementary, and roughly half of them are somehow related to persistent storage models. These basic questions could easily be

Today, we’re excited to announce that Platform9 is open-sourcing etcdadm, available under the Apache v2.0 license on GitHub. We’ve been working on this project for a while, and we’re stoked to now share it with the open source community at large to streamline the setup and ongoing operations of production etcd clusters. Inspired by kubeadm, etcdadm provides Kubernetes users
