Default HAProxy Options

Voyager Supports all valid options for defaults section of HAProxy config. You can provide these options using a json encoded map in Ingress annotations like below:

ingress.appscode.com/default-option: '{"http-keep-alive": "true", "dontlognull": "true", "clitcpka": "false"}'

This will be appended in the defaults section of HAProxy as:

option http-keep-alive
option dontlognull
no option clitcpka

If you don’t set the annotation {"http-server-close": "true", "dontlognull": "true"} will be considered as default value

Ingress Example:

apiVersion: voyager.appscode.com/v1beta1
kind: Ingress
metadata:
  name: test-ingress
  namespace: default
  annotations:
    ingress.appscode.com/default-option: '{"http-keep-alive": "true", "dontlognull": "true", "clitcpka": "false"}'
spec:
  rules:
  - host: voyager.appscode.test
    http:
      paths:
      - path: /foo
        backend:
          serviceName: test-server
          servicePort: 80
