HAProxy Load Balancer

HAProxy docker container million12/haproxy with ALPN and HTTP/2 support.

Features

• Support for HTTP/2 with ALPN
• CentOS 7 based
• Ability to provide any arguments to haproxy process
  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.
• Pretty lightweight, only ~290M (with OpenSSL and HAProxy compiled from source).
• Default haproxy.cfg provided for demonstration purposes. You can easily mount your own or point to different location using HAPROXY_CONFIG env.
• 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
