Knative has been accepted into the Cloud Native Computing Foundation (CNCF) as an Incubating project. Knative is an open source project based on Kubernetes for building, deploying, and managing serverless workloads, and has become the most widely-installed serverless layer on Kubernetes.

 It was originally developed by Google with contributions from more than 50 companies, and helps developers build, deploy, and manage modern serverless workloads on Kubernetes. It provides a set of building blocks designed to enable modern, source-centric and container-based development workloads on Kubernetes.

Knative has two main components: Knative Serving and Knative Eventing. The serving component is responsible for running serverless containers and managing the networking, autoscaling, and revision tracking. The eventing component handles event management, universal subscription and delivery.

Cloud Native Computing Foundation (CNCF) is part of the nonprofit Linux Foundation, and is the home for many of the fastest-growing open source projects, including Kubernetes, Prometheus, and Envoy.

The Knative Steering Committee said:

"This is a significant milestone for our project, and we are excited to join so many successful cloud native open source projects."

The developers say that now that the project has been officially accepted, they will continue moving the project infrastructure and supporting tooling over to the CNCF. Much of this was already underway as part of the team's previous work on open governance, and the team's goal is to minimize any potential disruptions to the project as this work is completed.

Knative was recently updated to version 1.2, with improvements including moving to use Kubernetes version v1.21 as a minimum, and improvements to the eventing component to standardize element names to kebab case. The server component added experimental support for PVC behind the feature flags. A persistent volume (PV) in Kubernetes defines the storage data, such as storage classes or storage implementations, and is a resource object in a Kubernetes cluster. To use a PV resource, it must be requested through persistent volume claims (PVCs).

Knative 1.2 is available now.
