Crowdsec with Traefik Bouncer

Let's protect your homelab with Crowdsec and Traefik Bouncer

Setup

Let's setup directories in your homefolder like so:

~/crowdsec
- compose.yml
- config
  - acquis.yaml

Basically:

mkdir crowdsec

cd crowdsec

touch compose.yml

mkdir config

touch acquis.yaml

Run

Go to the directory with the compose.yml

Run it with docker compose up -d

How to get the bouncer API key from crowdsec AND setup Traefik-Bouncer

After crowdsec is up and running run the following command:

docker exec crowdsec-example cscli bouncers add traefik-bouncer

Copy the API key printed. You WON'T be able the get it again.
Paste this API key as the value for bouncer environment variable CROWDSEC_BOUNCER_API_KEY in your compose.yaml
Uncomment that whole section and save it.
Recreate crowdsec with docker compose up -d --force-recreate

Integrate with Traefik (Final Step)

Go to the directory where traefik is setup.

If you have used my files, uncomment the parts in both traefik.yml and config.yml that is related to crowdsec and restart traefik using docker restart traefik

If you haven't used my files, refer to my traefik data folder and add those parts from my config.yml and traefik.yml.
