A Prometheus docker-compose stack

Here's a quick start to stand-up a Prometheus stack containing Prometheus, Grafana and Node scraper to monitor your Docker infrastructure. A big shoutout to philicious for kicking this project off!

##Pre-requisites Before we get started installing the Prometheus stack. Ensure you install the latest version of docker and docker-compose on your Docker host machine. This has also been tested with Docker for Mac and it works well.

##Installation & Configuration Clone the project locally to your Docker host.

If you would like to change which targets should be monitored or make configuration changes edit the /prom/prometheus.yml file. The targets section is where you define what should be monitored by Prometheus. The names defined in this file are actually sourced from the service name in the docker-compose file. If you wish to change names of the services you can add the "container_name" parameter in the docker-compose.yml file.

Once configurations are done let's start it up. From the /prometheus project directory run the following command:

$ docker-compose up -d

That's it. docker-compose builds the entire Grafa and Prometheus stack automagically.

The Grafana Dashboard is now accessible via: http://<Host IP Address>:3000 for example http://192.168.10.1:3000

username - admin password - foobar (Password is stored in the config.monitoring env file)

Post Configuration

Now we need to create the Prometheus Datasource in order to connect Grafana to Prometheues

• Click the Grafana Menu at the top left corner (looks like a fireball)
• Click Data Sources
• Click the green button Add Data Source.

Install Dashboard

I created a Dashboard template which is available on Grafana Docker Dashboard. Simply download the dashboard and select from the Grafana menu -> Dashboards -> Import

This dashboard is intended to help you get started with monitoring. If you have any changes you would like to see in the Dashboard let me know so I can update Grafana site as well.
