Ingress controllers

You need an ingress controller in your Kubernetes cluster. You can use the following for Obcerv:

• NGINX ingress controller
• HAProxy ingress controller

NGINX ingress controller

Installation

If you opt to install the ingress-nginx controller in your Kubernetes cluster, follow these steps.

1. Add the ingress-nginx Helm repo:

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

   Or update the repo if it already exists:

   helm repo update
   

2. Install the controller in the Obcerv’s namespace:

   helm install ingress-nginx ingress-nginx/ingress-nginx -n itrs
   

Configuration

Add the following annotation definitions to your Obcerv configuration file:

  apps:
    ingress:
      annotations:
        kubernetes.io/ingress.class: "nginx"
        nginx.org/mergeable-ingress-type: "master"
  ingestion:
    ingress:
      annotations:
