haproxy / docker No enabled listener found (check for 'bind' directives) ! Exiting

Question

I am trying to run haproxy with docker. I followed the instructions here :

https://hub.docker.com/_/haproxy/

I was able to build the docker image but after trying to run it.

using

docker run -d --link another_container:another_container --name mc-ha -v haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg:ro my_own_haproxy:latest

I get this error :

[ALERT] 298/054910 (1) : [haproxy.main()] No enabled listener found (check for 'bind' directives) ! Exiting.

I searched for it , but the only thing I found is the source code of ha proxy.

Here is my haproxy.cfg

global

    log /dev/log    local1 notice

EDIT: Btw I also tried changing the backend node url to my docker host ip. But still no luck.

Answer 1

Thanks to @Michael comment. I was able to solve the problem.

First I remove the haproxy command from the dockerfile. And then I run the haproxy command manually inside the container.

Voila! My config file is not a file. Its a directory. LOL

The problem is in my docker command -v.

I change it to full path

-v FULL_PATH/customhaproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg

You will want to remove the daemon keyword from your docker file - docker needs a foreground process to be running otherwise docker will exit immediately.

I think the error message you are seeing is because docker exits quicker than haproxy binds to any ports.
