duruu/haproxy repository overview

⁠HAProxy Load Balancer

This is a million12/haproxy⁠ docker container with HAProxy load balancer. This work is very similar to official dockerfile/haproxy⁠, but it's based on CentOS-7 and, more importantly, offers ability to provide any arguments to haproxy process. It's also pretty lightweight, only ~240M (vs. ~420M Ubuntu-based dockerfile/haproxy).

This container is built that any extra parameters provided to docker run will be passed directly to haproxy command. For example, if you run docker run [run options] million12/haproxy -n 1000 you pass -n 1000 to haproxy daemon.

The default haproxy.cfg⁠ is provided just for demonstration purposes, so of course you will want to override it.

⁠Auto restart when config changes

This container comes with inotify to monitor changes in HAProxy config and reload HAProxy daemon. The reload is done in a way that no connection is lost.

⁠ENV variables

HAPROXY_CONFIG
Default: HAPROXY_CONFIG=/etc/haproxy/haproxy.cfg
If you mount your config to different location, simply edit it.

⁠Usage

⁠Basic

docker run -ti -p 80:80 -p 443:443 million12/haproxy

⁠Mount custom config , override some options

docker run -d -p 80:80 -v /my-haproxy.cfg:/etc/haproxy/haproxy.cfg million12/haproxy -n 10000
Note: in this case config is mounted to its default location, so you don't need to modify HAPROXY_CONFIG variable.

⁠Check version and build options

docker run -ti million12/haproxy -vv

⁠Stats

The default URL for stats is http://CONTAINER_IP/admin?stats with username:password ser to admin:admin.
