Chapter 1. Getting started with OpenShift Serverless
You are viewing documentation for a release of Red Hat OpenShift Serverless that is no longer supported. Red Hat OpenShift Serverless is currently supported on OpenShift Container Platform 4.3 and newer.
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.
1.1. How OpenShift Serverless works
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.
1.2. Applications on OpenShift Serverless
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.
