The Prometheus and Alertmanager sandbox

This Dockerized and Docker Composed Prometheus and Alertmanager proof-of-concept project spins up:

• A Prometheus server
• A clustered Alertmanager (three containers)
• A helper service ehko that can e.g. receive alerts
• A blackbox-exporter that probes URLs and exports metrics

The Alertmanager cluster is fully meshed, every Alertmanager are configured with itself and all of the other Alertmanagers as cluster peers. To check the cluster status browse to: http://localhost:9001 (any active Alertmanger will be fine)

The script send_alert.sh sends a test alert to each one of the Alertmanagers.

Check out the config/ directory for all configuration files used in this proof-of-concept.

How-to:

1. Run the init.sh bash script to fix permissions on directories used by the different components of this PoC.
2. Run docker-compose to start the environment: docker-compose up -d

To clean up all data generated by the containers run the cleanup.sh script.
