HAProxy Enterprise Documentation 1.8r2

Global

The global section appears at the top of your configuration file. It defines process-level directives such as the maximum number of connections to accept, where to forward logs, and the path from which to load HAProxy Enterprise modules.

global
   # Bind the Runtime API to a UNIX domain socket and/or an IP address
   stats socket /var/run/hapee-1.8/hapee-lb.sock user hapee-lb group hapee mode 660 level admin
   stats socket ipv4@*:9024 level admin

   # Set a timeout for how long you can stay connected to the Runtime API,
   # which is useful for longer interactive terminal sessions
   stats timeout 10m

   # Set remote or local Syslog server addresses to send log files to
   log 127.0.0.1 local0
   log 127.0.0.1 local1 notice

   # Set the user and group to run HAProxy Enterprise as
   user  hapee-lb
   group hapee

   # Run the process in a chrooted directory
   chroot /var/empty

   # Set the path from which to load Enterprise modules
   module-path /opt/hapee-1.8/modules

Data Plane API

Install the Data Plane API.

You can manage the global section of your configuration remotely by calling the Data Plane API endpoint /services/haproxy/configuration/global.

Get the contents of a global section with the GET method:

$ curl -X GET \
    --user admin:adminpwd \
    "http://127.0.0.1:5555/v2/services/haproxy/configuration/global"

# output
{
   "_version":3,
   "data":
     {
        "cpu_maps":[],
        "module-loads":[],
        "runtime_apis":[{
            "address":"/var/run/hapee-1.8/api.sock",
            "level":"admin",
            "mode":"660"
         },
         {
            "address":"ipv4@0.0.0.0:9000",
            "level":"admin"
         }],
         "chroot":"/var/empty",
         "daemon":"disabled",
         "group":"hapee",
         "log_send_hostname": { "enabled":"disabled" },
         "lua_loads":[],
         "maxconn":100000,
         "pidfile":"/var/run/hapee-1.8/hapee-lb.pid",
         "ssl_mode_async":"disabled",
         "user":"hapee-lb"
      }
}

Replace the contents of a global section with the PUT method:

$ curl -X PUT \
    --user admin:adminpwd \
    -H "Content-Type: application/json" \
    -d '{
        "maxconn": 100000,
        "chroot": "/var/empty",
        "user": "hapee-lb",
        "group": "hapee",
        "pidfile": "/var/run/hapee-1.8/hapee-lb.pid",
        "runtime_apis": [{
            "address": "/var/run/hapee-1.8/api.sock",
            "exposeFdListeners": false,
            "level": "admin",
            "mode": "660"
        },
        {
            "address": "ipv4@0.0.0.0:9000",
            "exposeFdListeners": false,
            "level": "admin"
        }]
    }' \
