OpenShift Serverless is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see https://access.redhat.com/support/offerings/techpreview/.
OpenShift Serverless simplifies the process of delivering code from development into production by reducing the need for infrastructure set up or back-end development by developers.
Developers on OpenShift Serverless can use the provided Kubernetes-native APIs, as well as familiar languages and frameworks, to deploy applications and container workloads. For information about installing OpenShift Serverless, see Installing OpenShift Serverless.
OpenShift Serverless on OpenShift Container Platform enables stateful, stateless, and serverless workloads to all run on a single multi-cloud container platform with automated operations. Developers can use a single platform for hosting their microservices, legacy, and serverless applications.
OpenShift Serverless is based on the open source Knative project, which provides portability and consistency across hybrid and multi-cloud environments by enabling an enterprise-grade serverless platform.
A developer preview version of Knative Eventing is available for use with OpenShift Serverless. However, this is not included in the OpenShift Serverless Operator and is not currently supported as part of this Technology Preview. For more information about Knative Eventing, including installation instructions and samples, see the Knative Eventing on OpenShift Container Platform documentation.
The Knative Client (
kn) extends the functionality of the
kubectl tools to enable interaction with Knative components on OpenShift Container Platform.
kn allows developers to deploy and manage applications without editing YAML files directly.
Applications are created using Custom Resource Definitions (CRDs) and associated controllers in Kubernetes, and are packaged as OCI compliant Linux containers that can be run anywhere.
To deploy applications in OpenShift Serverless, you must create Knative Services. For more information see Getting started with Knative Services.
