Prerequisites¶

Tip

If you're installing Knative for the first time, a better place to start may be Getting Started.

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.
