The record

What it does: cdk8s is an open-source framework for defining Kubernetes applications and reusable abstractions with familiar programming languages and object-oriented APIs.
Manifest output: cdk8s synthesizes applications into standard Kubernetes YAML manifests that can be applied to Kubernetes clusters.
Programming languages: The site lists TypeScript, JavaScript, Python, Java, and Go as supported languages.
Kubernetes resources: Users can import objects from Kubernetes API versions and custom resource definitions.
Reusable abstractions: Constructs support composing higher-level abstractions with object-oriented classes, and can be shared through package managers.
Cluster compatibility: The project says cdk8s can define applications for Kubernetes clusters in any cloud or on premises, and runs locally in the development environment.
Deployment workflow: cdk8s generates manifests but does not apply them to a cluster; the docs describe applying them with kubectl or a GitOps tool such as Flux.
Integrations: The docs describe using cdk8s charts in an AWS CDK application and applying them with the EKS construct library.
Installation: The CLI installation page lists Homebrew, npm, and Yarn installation methods.
Community and support: The site provides community support links for issues, Stack Overflow, Slack, and a mailing list, and invites contributions.
Kubernetes version limit: cdk8s+ libraries are actively maintained only for the three latest Kubernetes releases.
Project affiliation: The homepage identifies cdk8s as a Cloud Native Computing Foundation Sandbox Project and says it is made at AWS.
