Sometimes when you run microk8s in AWS, you may want to have an application load balancer in front. Such configurations mess around with the value of the header X-Forwarded-For regardless of whether the append attribute is present on the load balancer. By reading the nginx ingress documentation, you need to edit the ConfigMap resource and add proxy-real-ip-cidr and use-forwarded-headers. You may also set compute-full-forwarded-for.
It only remains to figure out the name of the ConfigMap when ingress is installed with microk8s enable ingress. It is named nginx-load-balancer-microk8s-conf :
apiVersion: v1
kind: ConfigMap
metadata:
name: nginx-load-balancer-microk8s-conf
namespace: ingress
data:
proxy-real-ip-cidr: 172.31.0.0/16
use-forwarded-headers: "true"
