docker-elk: Error: No config files found

I’m trying to run this docker compose as is, without changing anything, and it fails with the following error:

logstash_1      | {:timestamp=>"2016-08-01T07:57:36.721000+0000", :message=>"No config files found: /etc/logstash/conf.d/logstash.conf\nCan you make sure this path is a logstash config file?", :level=>:error}

The config file exists, and contains the default configuration as per the cloned master branch of this repository.

Here is the full output of docker-compose up:
