Grafana - Docker Metrics on your desktop

---

Intro

With the introduction of Docker 1.13, docker metrics are now available as a prometheus feed. See https://blog.docker.com/2017/01/whats-new-in-docker-1-13/#h.i7yih1s9513y for more info

Setup Docker for Mac/Windows

In the Preference/Settings panel, update the daemon to include metrics:

{
	"metrics-addr":"0.0.0.0:9323"
}

Be careful with the above, as an incorrect setting will prevent docker from starting.

Start the Grafana stack with compose

docker-compose up -d

Manual setup

For Docker share its metrics, with Grafana, an actual prometheus daemon is needed

Add a small listener for the metrics, via prom/prometheus:

docker run -d --name prometheus -p 9090:9090 frenchben/prometheus

You can verify that the above worked, by visiting http://localhost:9090/metrics - You should see a prometheus-like output.

Running your Grafana image

Start your image binding the external port 3000.

docker container run -d -p 3000:3000 --name grafana frenchben/grafana

Try it out by navigating to http://localhost:3000/dashboard/db/prometheus-stats, default admin user is admin/admin.

The Docker dashboard was taken from https://grafana.net/dashboards/893, but feel free to add any dashboard you want, it will need some tweaking to work with the new Docker stats_
