Feature: Ability to clear log history

[djessup]

A feature I've thought would be useful since originally using Fig, and now Compose would be the ability to clear the log history for Composed-managed containers. Long-running or "chatty" containers can end up with a lot of log noise that may not be wanted.

I'd expect a command like the following would solve the problem:
$ docker-compose logs --clear [service]

I don't think that is a feature supported by the docker daemon. Looking at the api docs, the only option would be to truncate the returned logs to a limited number of lines per container:

https://docs.docker.com/reference/api/docker_remote_api_v1.17/#get-container-logs

👍 for this issue. I actually use compose to develop a website in Golang, Mongodb and nginx... 5 days after begining I have a long logs that becomes to be worrying. Each time I restart containers append many lines to the log.
@dnephin I don't understand if you give a solution (that I don't understand :)) or if you propose to check if it's possible with api. Sorry for my bad english.

Docker 1.6 will add support for logging drivers, see moby/moby#10568 (currently; JSON, syslog and "none") work is in progress for basic log-rotation; moby/moby#11485

Good to hear that, thanks a lot :)

Thanks for the background and update on Docker 1.6 - looking forward to it!

docker logs -c (clear) <container> would be great.

Holy cow, I just sat through several minutes of logs to get to the end. I'd really appreciate this as well for the sake of not having to rebuild containers constantly.
