Issue with default command?

[caussourd]

I'm running Docker 1.5 and haproxy:1.5

As a user pointed out on the Docker hub page, I had to override the command with haproxy -db -f /usr/local/etc/haproxy/haproxy.cfg to run the container.

With the default command (CMD ["haproxy", "-f", "/usr/local/etc/haproxy/haproxy.cfg"]), the container exits with no logs.

Apparently, the -db option allows haproxy to run in foreground: http://cbonte.github.io/haproxy-dconv/configuration-1.5.html#3.1

I'm +1 on fixing this, but I'm not sure -db is recommended for generic use:

-db
Disables background mode (stays in foreground, useful for debugging). For debugging, the '-db' option is very useful as it temporarily disables daemon mode and multi-process mode. The service can then be stopped by simply pressing Ctrl-C, without having to edit the config nor run full debug.

Isn't running haproxy single-threaded a bit of a problem?

Check your haproxy.cfg for daemon listed in the global mode. I was stumped on this as well until that jumped out at me in my config file. (I had just copied a config from another test haproxy instance I use on my workstation)

When I removed daemon, the docker image ran correctly in the foreground with the default image command.

That's it. Well spotted. Thanks @calh
