How to modify the Traefik access log verbosity in DKP 2.4.0?

By default Traefik access log level is set to WARNING. When troubleshooting access issues, for instance access to the DKP dashboard, the operator may need to increase the verbosity in Traefik logs so in this article we explain how to achieve this in DKP 2.4.

Solution

In DKP 2.4.0, Traefik default configuration is stored in the configmap “traefik-10.30.1-d2iq-defaults”. To override the default configuration, we should first identify which configmap should be modified with the values we’re looking to change. To do so we check the traefik appdeployment, specifically the value of the spec.configOverrides field:

kubectl --kubeconfig <kubeconfig> -n kommander get appdeployment traefik -ojsonpath='{.spec.configOverrides}' 
{"name":"traefik-overrides"}

Then we have to edit the traefik-overrides configmap:

kubectl --kubeconfig <kubeconfig> -n kommander edit cm traefik-overrides

And add the following values to increase the traefik access log verbosity:

logs:
  general:
    level: DEBUG
  access:
    enabled: true

This is how the correct format looks like:

apiVersion: v1
data:
  values.yaml: |    
    logs:
      general:
        level: DEBUG
      access:
         enabled: true
    service:
      annotations:
        service.beta.kubernetes.io/aws-load-balancer-internal: "true"
kind: ConfigMap
metadata:
  name: traefik-overrides
  namespace: kommander
