    /var/lib/config-data/puppet-generated/haproxy/etc/haproxy/haproxy.cfg on a Controller node.

listen horizon
  bind 10.0.0.111:80 transparent
  bind 172.17.1.84:80 transparent

  cookie SERVERID insert indirect nocache

Resolution

  • Create a environment file to pass option values to hieradata.

Example file path: /home/stack/templates/haproxy-custom-option.yaml

parameter_defaults:
  ControllerExtraConfig:
     tripleo::haproxy::horizon::options:
       option:
         - 'forwardfor'
         - 'httpchk'
         - 'httplog'
  • Please include any other options which have already been configured because all current options are overridden with above customized options.
  • And includes the environment file which created above in deploy command like this:
$ openstack overcloud deploy --templates \
    ...
    -e /home/stack/templates/haproxy-custom-option.yaml \
    ...
  • httplog option will be added to horizon settigns in haproxy.cfg after deploy was finished successfuly like this:
    /var/lib/config-data/puppet-generated/haproxy/etc/haproxy/haproxy.cfg on Controller node
listen horizon
  bind 10.0.0.111:80 transparent
  bind 172.17.1.84:80 transparent
  mode http
  cookie SERVERID insert indirect nocache
  option forwardfor
  option httpchk
  option httplog   <======== here
  server controller-1.internalapi.redhat.local 172.17.1.24:80 check cookie controller-1.internalapi.redhat.local fall 5 inter 2000 rise 2
  server controller-2.internalapi.redhat.local 172.17.1.39:80 check cookie controller-2.internalapi.redhat.local fall 5 inter 2000 rise 2
  server controller-0.internalapi.redhat.local 172.17.1.57:80 check cookie controller-0.internalapi.redhat.local fall 5 inter 2000 rise 2
