UPDATE (2020): Since this was written 3 years ago, many things have changed (including my opinion about this topic). My suggested way of doing this, is using one dockerfile and using scripts. Please see @yamenk's answer.

ORIGINAL:

You can use two different Dockerfiles.

# ./Dockerfile (non production)
FROM foo/bar
MAINTAINER ...

# ....

And a second one:

# ./Dockerfile.production
FROM foo/bar
MAINTAINER ...

RUN composer install

While calling the build command, you can tell which file it should use:

$> docker build -t mytag .
$> docker build -t mytag-production -f Dockerfile.production .
