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 (Nginx, Traefik or Istio), cluster issuer or cert-manager installed in the cluster, the steps below specific to each are not necessary.
If not already present in your cluster, you can install cert-manager by using the following commands:
kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.5.3/cert-manager.yaml
Apps deployed using Ketch require an ingress controller, it uses its IP address to generate deployed application dns name that can be used to access the application
Ketch supports nginx, istio and traefik ingress controllers. See table below for supported versions of these ingress controllers.
If you have one of these ingress controllers already installed you can use them or install one or more of these. Once available you can use their IP address during ketch framework creation.
If not already present in your cluster, you can run following helm command to install Nginx ingress. For details see: https://kubernetes.github.io/ingress-nginx/deploy/.
helm upgrade --install ingress-nginx ingress-nginx \ --repo https://kubernetes.github.io/ingress-nginx \ --namespace ingress-nginx --create-namespace
If not already present in your cluster, you can install traefik using following command. For details see https://doc.traefik.io/traefik/getting-started/install-traefik/#use-the-helm-chart.
helm repo add traefik https://helm.traefik.io/traefik helm repo update helm install traefik traefik/traefik
If not already present in your cluster, you can install Istio as the ingress controller of choice by using the following commands or follow instructions at: https://istio.io/latest/docs/setup/install/
ISTIO_VERSION=1.9.0 && curl -L https://istio.io/downloadIstio |ISTIO_VERSION=1.9.0 sh - && cd istio-$ISTIO_VERSION && export PATH=$PWD/bin:$PATH istioctl install --set profile=demo
