Requirements

Supported Kubernetes versions

Keptn requires Kubernetes v1.24.0 or later.

Run the following to ensure that both client and server versions are running Kubernetes versions greater than or equal to v1.24. In this example, both client and server are at v1.24.0 so Keptn will work.

kubectl version --short

Client Version: v1.24.0
Kustomize Version: v4.5.4
Server Version: v1.24.0

Keptn is not currently compatible with vcluster.

Resource requirements

cert-manager

Keptn includes a lightweight cert-manager that is used for installation and Webhooks. You can configure a different cert-manager before you install Keptn. See Implement your own cert-manager for instructions.
