This plugin has been merged into Heka core under the name DockerLogInput. Just use that instead :-)
Docker input plugin for Mozilla Heka. Heavily based on progrium/logspout and victorcoder/heka-redis.
The plugin connects to the Docker socket, pulls all log messages (stdout/stderr) from all running containers and converts them into Heka messages.
See Building hekad with External Plugins for compiling in plugins.
