Installing the Knative CLI

    The Knative CLI (kn) provides a quick and easy interface for creating Knative resources, such as Knative Services and Event Sources, without the need to create or modify YAML files directly.

    The kn CLI also simplifies completion of otherwise complex procedures such as autoscaling and traffic splitting.

    • To install kn by using , run the command (Use brew upgrade instead if you are upgrading from a previous version):

      Having issues upgrading kn using Homebrew?

      If you are having issues upgrading using Homebrew, it might be due to a change to a CLI repository where the master branch was renamed to main. Resolve this issue by running the command:

      1. brew uninstall kn
      2. brew untap knative/client --force

    1. Rename the binary to kn and make it executable by running the commands:

      1. mv <path-to-binary-file> kn
      2. chmod +x kn

      Where <path-to-binary-file> is the path to the binary file you downloaded in the previous step, for example, kn-darwin-amd64 or kn-linux-amd64.

    2. Move the executable binary file to a directory on your PATH by running the command:

    3. Verify that the plugin is working by running the command:

      1. kn version

    4. Check out the kn client repository:

      1. cd client/

    5. Build an executable binary:

      1. kn version

    Links to images are available here:

    You can run kn from a container image. For example:

    1. docker run --rm -v "$HOME/.kube/config:/root/.kube/config" gcr.io/knative-releases/knative.dev/client/cmd/kn:latest service list

    Note

    Running kn from a container image does not place the binary on a permanent path. This procedure must be repeated each time you want to use kn.

    Warning

    Nightly container images include features which may not be included in the latest Knative release and are not considered to be stable.

    Nightly-built executable binaries are available for users who want to install the latest pre-release build of kn.
