Can't use docker-gen notify-sighup with Docker Cloud, container names are dynamic

[christiansyoung]

I am trying to use docker-gen together with an nginx container on Docker Cloud. I am having trouble with the sighup sent by docker-gen when e.g. my application containers changes config. Docker Cloud generates random names for my containers, e.g. nginx-test-1.test.7321ba3a. I can't specify container_name in the Docker Cloud Stack YAML file as you can with docker-compose.

The error I get is:

Sending container 'nginx-test' signal '1'
Error sending signal to container: No such container: nginx-test

Is there any way to utilize e.g. links: nginx-test or something to work around this? Alternatives? I don't know Go, so I am having trouble looking over the code.

Not currently. #77 sounds similar. I think docker-gen would need to be able to signal a container using something other than names. Possibly labels, images, etc.. That is not possible right now.

It really sucks that I am not able to use this on Docker Cloud
