For more information about this image and its history, please see the relevant manifest file (library/haproxy) in the docker-library/official-images GitHub repo.
HAProxy is a free, open source high availability solution, providing load balancing and proxying for TCP and HTTP-based applications by spreading requests across multiple servers. It is written in C and has a reputation for being fast and efficient (in terms of processor and memory usage).
Since no two users of HAProxy are likely to configure it exactly alike, this image does not come with any default configuration.
Please refer to upstream's excellent (and comprehensive) documentation on the subject of configuring HAProxy for your needs.
It is also worth checking out the examples/ directory from upstream.
