Setup Kubernetes cluster

ArconQ is a cloud-native framework that requires Kubernetes. If you do not have your own Kubernetes cluster, you can use microk8s, which is an easy to install and configure Kubernetes distribution.

Configure microk8s environment​

For development purpose you can use microk8s cluster installed locally on your PC.

caution

It is up to you to verify whether you comply with microk8s and its add-ons licenses.

note

Official microk8s manual is available here for Linux and Windows.

Ingress​

Make sure the ingress controller installed in your cluster is Ingress-Nginx Controller (https://kubernetes.github.io/ingress-nginx/) and not NGINX Ingress Controller.

You can install or upgrade the NGINX Ingress Controller using Helm with the following command:

helm upgrade --install ingress-nginx ingress-nginx \
  --repo https://kubernetes.github.io/ingress-nginx \
  --namespace ingress-nginx --create-namespace \
  --set controller.allowSnippetAnnotations="true" \
  --set controller.config.annotations-risk-level="Critical"
