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

name: haproxy
namespace: haproxy-controller
data:
syslog-server: "address:stdout, format: raw, facility:daemon"
You will then see access logs:
