Knative focuses on three key areas - building an application, serving traffic to it, and enabling applications to easily consume and produce events. This post looks at the fundamental concepts of Knative such as Knative Serving, Knative Eventing and Knative build. It also looks at the details of service, configuration, Revision and routes which are part of Knative Serving. It looks at the details of Messaging, Channel, Subscription, sources and sinks which are part of Knative eventing.

Kubernetes Storage concepts Applications that run on Kubernetes can be stateless or stateful. Kubernetes abstracts away persistent storage from ephemeral pods and containers. Kubernetes provides the ability to dynamically create storage resources. The Kubernetes storage architecture is based on volumes as the primary abstraction. Volumes are created and managed by Kubernetes. It is bound to pods and containers. Volumes are attached to the nodes where the pods and containers are running. Volumes are mounted to the containers and are bound to persistent storage. ...

Container images are a popular and standard format to package applications. Building secure, high performance container images can be challenging. Cloud native buildpacks provide solutions to create container images that are secure, high performance, and easy to deploy.

In this post we will deploy MS Sql Server in a kubernetes cluster. We will then configure it as an always on availability group.We will also look at synchronization and failover.

Tekton provides a cloud-native, standardized set of building blocks for CI/CD systems. It runs natively on Kubernetes and can target any platform, language, or cloud. It extends the Kubernetes API and provides custom resources to create CI/CD pipelines.

In this post we will walk through steps to create a Knative serving instance on a local Kind cluster. We will deploy kourier as the networking layer. We will then deploy an application on this cluster and see it scaling up and down

In this post we will deploy gatekeeper to a kubernetes cluster. We will then define constraints and ensure that gatekeeper enforces those constraints.

OPA Gatekeeper is a Kubernetes-native policy controller that enables resource validation and audit functionality for a Kubernetes cluster.

Admission controllers provide extension points that augment Kubernetes functionality. Admission controllers determine if the request is well-formed and approve or reject the API request.

The Open Policy Agent (OPA) is a policy engine to author declarative policies as code and use those policies as a component of the decision-making process.
