Recap - Embed Containers and Kubernetes into vSphere

When VMware released vSphere 7 back in 2020, it was announced that under the hood a lot of architectural efforts flowed into VMware’s core platform. These efforts had to be done in order to embed containers and Kubernetes into vSphere, to unify them with virtual machines as first class citizens.

Event-Driven Automation with Project Harbor and Knative

Robert Guske published on 2022-07-04 included in Platforms Serverless Open-Source

The open-source container registry Harbor supports the configuration of webhook endpoints. Harbor notifies the webhook endpoint of certain events that occur in a project. However, the event sent is not delivered as a CloudEvent. By leveraging the power of VEBA/Knative the non-CloudEvent can be send to a webhook function to get transformed in a CloudEvent. By transforming the event, other functions can be subscribed to the new event to ultimately get triggered. As a use case for it, I'm going to describe how ChatOps can be enabled using event-driven automation.

Why a Kubernetes-Appliance?

Learning Kubernetes (K8s) is still in great demand and is by no means decreasing. Starting with the theory is essential but we all know, the fun part starts with pactice. Quickly instantiating a Kubernetes cluster is made easy and I’m pretty sure it won’t take long until KinD crosses your path. But sometimes, a local K8s instance isn’t enough and practicing Kubernetes low-level implementations like e.g. for networking (CNI) or storage (CSI) on real cloud environments is crucial.

Sometimes you gotta run before you can walk!
