The source code for this lab exercise is available on GitHub. GitOps is the practice of delivering infrastructure and applications in a declarative manner based on a single, authoritative source of truth. Oftentimes, the source of truth is defined within a Git repository, hence the term GitOps, though recent developments have…

Ceph is a distributed, scalable, fault-tolerant solution for provisioning block, file and object storage to applications. While deploying Ceph to Kubernetes with Rook is simple and is sufficient for most Kubernetes use cases, certain scenarios may benefit from configuring Rook with an external Ceph cluster instead or as an additional option:…

The source code for this lab exercise is available on GitHub. In our previous article Running stateful workloads on Kubernetes with Rook Ceph, we saw how Kubernetes CSI enables us to take volume snapshots on supported storage backends as a first step towards protecting our data on Kubernetes. However, snapshots operate at the infrastructure…
