+
+This is a simple Fail2Ban prometheus exporter
+
+## Installation
+
+### From source
+You can clone this repository from git `https://github.com/glvr182/f2b-exporter.git`.  
+Then all you have to do is run `go build` and you're done!
+
+### Docker
+Using the following command you can run this program with docker.  
+NOTE: When running the docker image you might want to mount the certificates since some remotes use TLS.
+```
+docker run \
+-d \
+--name f2b-exporter \
+-v /var/lib/fail2ban/fail2ban.sqlite3:/var/lib/fail2ban/fail2ban.sqlite3 \
+-v /etc/ssl/certs:/etc/ssl/certs \
+glvr182/f2b-exporter
+```
+Depending on your deployment you might want to expose the configured port (default 8080) like this:
+```
+docker run \
+-d \
+-p 8080:8080 \
+--name f2b-exporter \
+-v /var/lib/fail2ban/fail2ban.sqlite3:/var/lib/fail2ban/fail2ban.sqlite3 \
+-v /etc/ssl/certs:/etc/ssl/certs \
+glvr182/f2b-exporter
+```
+
+## Configuration
+The exporter has a few settings that you can tweak using the cli or using env variables:
+| cli        | env          | default                            |
+|------------|--------------|------------------------------------|
+| --port     | F2B_PORT     | 8080                               |
+| --database | F2B_DATABASE | /var/lib/fail2ban/fail2ban.sqlite3 |
+| --remote   | F2B_REMOTE   | freeGeoIP                          |
+
+To add the exporter to prometheus a simple config like this would do the trick:  
+NOTE: this is from prometheus, NOT for this exporter.
+```
+global:
+  scrape_interval:     15s
+  evaluation_interval: 15s
+
+scrape_configs:
+  - job_name: 'f2b-exporter'
+    scrape_interval: 5s
+    static_configs:
+    - targets: ['localhost:8080']
+```
+Or using docker and a dedicated network:
+```
+global:
+  scrape_interval:     15s
+  evaluation_interval: 15s
+
+scrape_configs:
+  - job_name: 'f2b-exporter'
+    scrape_interval: 5s
+    static_configs:
+    - targets: ['f2b-exporter:8080']
+```
