Prerequisites

Before installing Knative, you must meet the following prerequisites:

System requirements

For prototyping purposes, Knative will work on most local deployments of Kubernetes. For example, you can use a local, one-node cluster that has 2 CPU and 4GB of memory.

For production purposes, it is recommended that:

• If you have only one node in your cluster, you will need at least 6 CPUs, 6 GB of memory, and 30 GB of disk storage.
• If you have multiple nodes in your cluster, for each node you will need at least 2 CPUs, 4 GB of memory, and 20 GB of disk storage.

NOTE: The system requirements provided are recommendations only. The requirements for your installation may vary, depending on whether you use optional components, such as a networking layer.

Prerequisites

Before installation, you must meet the following prerequisites:

• You have a cluster that uses Kubernetes v1.18 or newer.
• You have installed the kubectl CLI.
• Your Kubernetes cluster must have access to the internet, since Kubernetes needs to be able to fetch images. (To pull from a private registry, see Deploying images from a private container registry)

Next Steps: Install Knative Serving and Eventing

You can install the Serving component, Eventing component, or both on your cluster. If you’re planning on installing both, we recommend starting with Knative Serving.

• Installing Knative Serving using YAML files
• Installing Knative Eventing using YAML files
