Install Knative components

Install Knative using the konk script

You can get started with a local deployment of Knative by using Knative on Kind (konk):

Install Knative and Kubernetes on a local Docker Daemon using konk

curl -sL install.konk.dev | bash

konk is a shell script that completes the following functions:

1. Checks if you have kind installed, and creates a cluster called knative.
2. Installs Knative Serving with Kourier as the default networking layer, and nip.io as the DNS.
3. Installs Knative Eventing and creates a default broker and channel implementation.

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

Installing the kn CLI

Using Homebrew

For macOS, you can install kn by using Homebrew.

brew install knative/client/kn

Using a binary

You can install kn by downloading the executable binary for your system and placing it in the system path.

A link to the latest stable binary release is available on the kn release page.

Using Go

1. Check out the kn client repository:

   git clone https://github.com/knative/client.git
   cd client/
   

2. Build an executable binary:

   hack/build.sh -f
   

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

   kn version
   

Using a container image

Warning

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

Links to images are available here:

• Latest release
• Nightly container image

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

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.

Note

For more complex installations, such as nightly releases, see Install kn
