Cluster configuration

Simple setup on an existing cluster

TLDR;

  1. Create Kubernetes cluster (e.g minikube or google cloud)
  2. Initialize kubectl credentials to work with your cluster
  3. Run source cluster-init.sh (This script installs the ingress-nginx controller and cert-manager using Helm in the configured k8s cluster.)

Cert-manager

Follow this instructions to deploy cert-manager

Ingress

Ingress controller is the entry point of all cloudharness applications. Info on how to deploy nginx-ingress can be found here.

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install ingress-nginx ingress-nginx/ingress-nginx

On localclusters and GCP/GKE, the nginx-ingress chart will deploy a Load Balancer with a given IP address, while in other environments, you may need to configure the Load Balancer manually. Use that address to create the CNames and A records for the website.

GCP GKE cluster setup

GKE setup is pretty straighforward. Can create a cluster and a node pool from the google console and internet facing load balancers are directly created with the ingress controller.

For additional info see here.

AWS EKS setup

AWS requires come additional steps to install the load balancer and the ingress, see here
