Build scripts for HAProxy with QUIC
PROJECT STATUS: STABLE. We have been using it in our own production systems for months now without issues. If you rely on it for critical purposes, maintain your own fork, so that a potential tagging/CI issue doesn't cause you problems.
docker run -it \
-v /path/to/haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg:ro \
-p "80:80" \
-p "443:443/tcp" \
-p "443:443/udp" \
HTTP/3 and QUIC
NOTE FOR QUIC: docker and docker-compose require explicit UDP protocol port mapping, otherwise they assume only-TCP. See the explicit port-mapping above.
Here's a sample configuration (requires you to figure out the certificate) to test HTTP/3.0 support. The first connection should be over HTTP/1.1 or HTTP/2, and after a few refreshes it should be over HTTP/3.
See Announcing HAProxy 2.6 for more info.
bind :443 ssl crt /usr/local/etc/haproxy/cert.pem alpn h2,http/1.1
bind quic4@:443 ssl crt /usr/local/etc/haproxy/cert.pem alpn h3
http-after-response set-header alt-svc 'h3=":443"; ma=86400'
http-request return status 200 content-type text/plain lf-string "Connected via %HV"
You will need the following dependencies (Debian/Ubuntu packages given as example):
- Development tools (
- curl and ssl support for it (
- CMake (
- Readline library headers (
- Libsystemd headers (
- GNU TAR (
Then just run
make and the build should pass.
deps/quictls/quictls-dist.tar.gz should be expanded so it matches the
/opt/quictls when expanding, as it is where HAProxy will look for OpenSSL.
haproxy/haproxy-dist.tar.gz can be expanded anywhere.
Compatibility of binaries
You may acquire binaries for non-docker usage in 2 ways:
- We distribute binary tarballs for this repo in the project's packages
- You can build it locally, which results in
Please note that neither QuicTLS/OpenSSL nor HAProxy are fully statically
compiled. They are still linking to glibc. You see that
readelf -d /path/to/binary.
As a result, you may be unable to run a binary linked using a more recent glibc.
Our CI uses the most recent Debian Buster image for compilation. You can find
out the exact libc version this links against with
ldd --version like so:
$ docker run -it debian:buster ldd --version | head -n1
ldd (Debian GLIBC 2.28-10+deb10u1) 2.28
Particular care should thus be put in what host you use for compilation.
Similarly, if you generally enjoy running abandonware you will not be able to use any of our non-docker artifacts.
Should I use this repo?
This is an:
- unofficial build of HAProxy
- which enables an experimental feature of HAProxy
- which relies on an unofficial build of OpenSSL
- which is based on an unofficial patch of OpenSSL
Generally speaking, you shouldn't.
That said, please PR improvements back if you do. We'll be using it ourselves too.
What's in there
First, we want to statically build things where possible, which is done for:
- QuicTLS (partially, still links to host glibc)
Then we want HAProxy to not use the system's OpenSSL but rather our QuicTLS
it will look for at the
About Debian packaging
The content of haproxy/debian is a slightly modified version of the Debian HAProxy Team's work and essentially all credits wrt that is due to them.

Since we're building our own binaries, we also increase MAX_SESS_STKCTR to 5 instead of the default of 3. If you don't know what that is, it's irrelevant to you. You can read some more here.
