Logging

When you install the ingress controller, it captures logs from the controller itself. Use kubectl logs to view the logs of the ingress controller pod:

$ kubectl logs kubernetes-ingress-7d84545b45-fpzm9

By default, this will not include access logs from requests and responses. However, by adding the following ConfigMap to your cluster, access logs will also be displayed when you call kubectl logs.

apiVersion: v1
kind: ConfigMap
metadata:
  name: haproxy
  namespace: haproxy-controller
data:
  syslog-server: "address:stdout, format: raw, facility:daemon"

You will then see access logs:
