Installing kn

This guide provides details about how you can install the Knative kn CLI.

Installing the kn CLI

For macOS, you can install kn by using Homebrew.

brew install kn


Quickstart requires kn version 0.25 or later. To upgrade an existing install to the latest version, run brew upgrade kn.

You can install kn by downloading the executable binary for your system and placing it in the system path. Note that you will need kn version 0.25 or later.

  1. Download the binary for your system from the kn release page.

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

    mv <path-to-binary-file> kn
    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.

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

    mv kn /usr/local/bin
  4. Verify that the plugin is working by running the command:

    kn version
  1. Check out the kn client repository:

    git clone
    cd client/
  2. Build an executable binary:

    hack/ -f
  3. Move kn into your system path, and verify that kn commands are working properly. For example:

    kn version

Links to images are available here:

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

docker run --rm -v "$HOME/.kube/config:/root/.kube/config" service list


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.

Having issues upgrading kn?

If you are having issues upgrading using Homebrew, it may be due to a change to a CLI repository, where master branch was renamed to main. If so, run

brew tap --repair
brew update
brew upgrade kn

to resolve the issue.

Install kn using the nightly-built binary


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.

Links to the latest nightly-built executable binaries are available here:
