Would you like to run functions in your own Kubernetes clusters? Would you like it to be as simple as possible? How about providing Functions As a Service (FaaS) flavor of serverless computing to everyone in your company? If the answer to any of those questions is yes, you might want to explore Knative Functions.
Continue readingHow can we enable application developers to be self-sufficient instead of opening JIRA tickets requesting deployment of their apps to Kubernetes, creation of databases, clusters, etc.? In this video, I’m trying to answer that question through an example of a stateful application running in Kubernetes and connected to a database. To accomplish that, I’ll use Crossplane, SchemaHero, Okteto, and a bit of Bash scripting.
Continue readingSometimes, when defining Kubernetes manifests, YAML or templating is not enough. Sometimes, we do want a “real” language like Go, TypeScript, Python or Java as an engine that will generate Kubernetes manifests. That’s where cdk8s comes into play. In this video, we will see how to use cdk8s to create Kubernetes manifests.
Continue readingKubernetes is not only about containers. Here’s a proof that we can also run virtual machines in the same way we run containers. In this video, I’ll show you how to create and manage virtual machines with KubeVirt.
Continue readingDatree is known as a great solution for client-side manifest scanning and policy enforcement. That just changed with the introduction of Kubernetes admission controllers. Datree now supports both, so it’s time to revisit the project and see whether it is a good choice for server-side validations and policy enforcement.
Continue readingIngress and service mesh specifications are about to be replaced with Gateway API. Let’s see it in action!
Continue readingWhy don’t we use “pure” YAML to define Kubernetes resources? Wouldn’t that be more “GitOps friendly” than using Helm templates or Kustomize overlays? Can kpt get us back to “pure” YAML?
Continue readingCan we build container (Docker) images without Dockerfile? Do we need Dockerfile or can we accomplish the same or better results with Buildpacks, Paketo, and kpack?
Continue readingWhat is Kubernetes (k8s)? A container orchestrator? Cluster OS? A control plane? Something else?
Continue readingWhat is autoscaling? How to scale applications and Kubernetes clusters? What is the difference between vertical and horizontal scaling? Should we combine Horizontal Pod Autoscaler (HPA), Vertical Pod Autoscaler (VPA), and Cluster Autoscaler (CA) in Kubernetes?
