Exposes Docker metrics over a Prometheus endpoint

Docker Watch

Uses Prometheus Node Exporter as a base. Removed all node_exporter collectors and added two for docker.

These collectors hit the Stats and Inspect API's. I've only picked out the few metrics which are interesting to me, adding more should be trivial.

This is all pretty hacky, so pull requests welcome.

Docker

docker run \
  --rm \
  -p 9100:9100 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  alexrudd/docker_watch

curl localhost:9100/metrics

Building

Included a small build script which statically compiles the Go binary and runs the Docker build command

./build.sh
