aasmith/docker-haproxy

HAProxy compiled against newer/faster libraries (PCRE w/ JIT, SLZ).

This haproxy docker image uses statically-linked modern libraries where possible. Otherwise, it attempts to follow the official docker image as closely as possible. Substitute the image name where needed, as in the example below.

Available Versions

For a complete list of docker tags you can use, see: https://hub.docker.com/r/aasmith/haproxy/tags/

Branches

1.6 1.7 1.8 lua lua-1.6 lua-1.7

Usage

Example Dockerfile:

FROM aasmith/haproxy
COPY haproxy.cfg /usr/local/etc/haproxy/haproxy.cfg

To pin to a specific version, use the branch or tag:

FROM aasmith/haproxy:1.8 # stay on the latest the 1.8 line

FROM aasmith/haproxy:1.8.0 # use exactly 1.8.0

Lua

A lua version is also available on the lua branch:

FROM aasmith/haproxy:lua # latest lua

FROM aasmith/haproxy:lua-1.6.10

The lua version also includes the luarocks package manager.

For more information about using these images, see the offical docker image instructions at https://github.com/docker-library/docs/tree/master/haproxy#how-to-use-this-image.

Libraries

PCRE

Enables PCRE JIT compilation for faster regular expression parsing. The PCRE Peformance Project has more information on benchmarks, etc.

Compilation follows as close as possible to the debian package, excluding C++ support and dynamic linking.

Stateless Zip (SLZ)

Created by the HAProxy maintainer, SLZ is a stream compressor for producing gzip-compatible output. It has lower memory usage, no dictionary persistence, and runs about 3x faster than zlib.

See the Stateless Zip project for background, benchmarks, etc.
