docs: haproxy.org/server-ssl tip is misleading

[Karitham]

Hi, I was recently setting up a service that terminated tls by itself. I was having trouble and fucked around with this setting.

The tip says Enable HTTP/2 support for backend severs., which is surely not what this entries does.

kubernetes-ingress/documentation/doc.yaml

Line 1514 in f8e12cd

- Enable HTTP/2 support for backend severs.

I still do not understand what it does so I can't fix it.

Hi @Karitham , Can you exactly explain what is misleading ?The tip says that it enables HTT2 support for backend servers which it does. If I take two examples without and with the annotation set, you've got:

backend XXXX
  mode http
  balance roundrobin
  option forwardfor
  no option abortonclose
  timeout server 50000
  default-server check
  server SRV_1 10.244.0.8:80 enabled
  server SRV_2 127.0.0.1:80 disabled
  server SRV_3 127.0.0.1:80 disabled
  server SRV_4 127.0.0.1:80 disabled

and

backend XXXX
  mode http
  balance roundrobin
  option forwardfor
  no option abortonclose
  timeout server 50000
  default-server check ssl alpn h2,http/1.1 verify none
  server SRV_1 10.244.0.8:80 enabled
  server SRV_2 127.0.0.1:80 disabled
  server SRV_3 127.0.0.1:80 disabled
  server SRV_4 127.0.0.1:80 disabled
