HAProxy 1.7 Using the REST API


I want to use HAProxy’s REST API to deploy load-balancer changes to my cluster. I’m following the documentation here:

I’ve started up a docker instance using the official alpine build:

docker run -d -v /ops/haproxy:/usr/local/etc/haproxy --name haproxy -p 80:80 -p 4444:4444 haproxy:1.7.2-alpine

The instance comes up and I’ve confirmed that it’s listening on 80 and 4444. According to the documentation the API should be on port 4444:

A minimal curl request would be:
curl -k -u admin:admin

However when I try to connect to the API it’s failing:

$curl -k -u admin:admin
curl: (35) Unknown SSL protocol error in connection to
curl: (56) Recv failure: Connection reset by peer

When I use --net=host instead of manual port binding HAProxy is only binding port 80 - which is defined in my haproxy.cfg.

How do I connect to the API and set authentication to use it, i.e. change admin:admin to something a little harder to guess?


Sorry, was looking at aloha ;(
