Prerequisites

Before installing Knative, you must meet the following prerequisites:

  • 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.

    Tip

    You can install a local distribution of Knative for development use by following the Getting started guide.

  • 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.
  • 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.
