HAProxy Enterprise Documentation 1.6r2
Dynamic-update
The dynamic-update section lets HAProxy Enterprise pull updated ACL and Map files from a remote server. This allows a cluster of HAProxy Enterprise instances to stay in sync.
Tip
In order to use the dynamic-update section you first need to install HAProxy Enterprise's Update module.
$ # On Debian/Ubuntu
$ sudo apt-get install hapee-1.6r2-lb-update
$ # On CentOS/RedHat/Oracle
$ sudo yum install hapee-1.6r2-lb-update
After the Update module is installed, we can list one or more update lines in a dynamic-update section. Each specifies a file to pull from a remote server to the current load balancer instance.
