The Ketch Developer Hub

Welcome to the Ketch developer hub. You'll find comprehensive guides and documentation to help you start working with Ketch as quickly as possible, as well as support if you get stuck. Let's jump right in!

Get Started    

Getting Started

Getting started with Ketch only takes a few minutes. The sections below will guide you step-by-step from installing Ketch to deploying your first application.

More in-depth tutorials can also be found as part of this documentation.

Installing Ketch

The latest Ketch release can be found here. Use the following commands to install Ketch, changing the version in the commands to match the version of Ketch you want to install.

Ketch CLI

You can use the following command to download and install the Ketch CLI on your local machine:

curl -s | bash

The command above will download and install the Ketch CLI based on your local operating system

Ingress Controller, Cluster Issuer and Cert Manager


Existing cluster resources

The ingress controller, cluster issuer, or cert-manager should only be installed if one is not currently installed in the cluster where Ketch will be installed.

In case there is already an ingress controller (Traefik or Istio), cluster issuer or cert-manager installed in the cluster, the steps below specific to each are not necessary.

* Installing Cert-Manager

If not already present in your cluster, you can install cert-manager by using the following commands:

kubectl apply --validate=false -f

* Installing Traefik

If not already present in your cluster, you can install Traefik by using the following commands:

helm repo add traefik
helm repo update
helm install traefik traefik/traefik

* Installing Istio

If not already present in your cluster, you can install Istio by using the following commands:

curl -L | sh -
export PATH=$PWD/istio-1.8.1/bin:$PATH
istioctl install --set profile=demo

* Cluster Issuer

If not already present in your cluster, you can install a cluster issuer by creating the cluster-issuer-istio.yaml file with the following content:

kind: ClusterIssuer
  name: le 
      name: my-account-key
    - http01:
         class: istio

Once the file is created, you can install it using the following command:

kubectl apply -f cluster-issuer-istio.yaml

Ketch Controller

Run the command below to install the Ketch controller:

kubectl apply -f

Deploying an Application

Creating a Pool

Deploying applications is easy once you've installed Ketch, where the first step is to create a pool.

When creating a pool, you should assign which ingress controller you want to associate with the pool.

  • When using Traefik:
ketch pool add dev  --ingress-service-endpoint --ingress-type traefik
  • When using Istio:
ketch pool add dev  --ingress-service-endpoint --ingress-type istio


Kubernetes Namespace

The commands above will create a dedicated namespace for the Ketch pool during the pool creation.

You can also have Ketch use an existing namespace for the pool instead. This can be achieved by adding the --namespace flag in the command

Creating an Application

By using the command below, you will create an application named bulletinboard and assign it to the pool dev created in the previous step:

ketch app create bulletinboard --pool dev

Deploying the Application

The command below will deploy an existing Docker image as your application image to bulletinboard:

ketch app deploy bulletinboard -i

Once deployed, you can check the application status by using the app list command:

ketch app list

After you deploy your application, you can access it at the address associated with it using the ketch app list, in this example,
