I created this container as a way to generate a fail2ban grafana dashboard when running fail2ban in a container. All the exporter solutions I could find relied on fail2ban running on metal and not in a container. This solution will work with either scenario.
f2bgrafanaexporter will log all ban instances without clearing old entries. If your jails don't perma ban and the desire is to only show statistics for actively banned addresses, then this isn't the solution for you. f2bgrafanaexporter will update the dashboard once an hour.
services:
f2bgrafanaexporter:
image: ghcr.io/thetaylorlee/f2bgrafanaexporter:latest
container_name: f2bgrafanaexporter
environment:
- fail2bandatabase='fail2ban.sqlite3' # This is the name of your fail2ban database. If your f2b install uses a different database name then this should be different.
volumes:
- /home/user/docker/fail2ban:/f2bgrafanaexporter/db # This is where the existing fail2ban database is stored and where the exporter db will be stored
- /home/user/docker/f2bgrafanaexporter/logs:/f2bgrafanaexporter/logs # This volume is where logs will be stored
restart: unless-stopped
