Crowdsec configuration

CrowdSec has a main yaml configuration file, usually located in /etc/crowdsec/config.yaml.

Configuration example

  daemonize: true
  pid_dir: /var/run/

prometheus:
  enabled: true
  level: full
  listen_addr: 127.0.0.1
  listen_port: 6060

Environment variable

It is possible to set a configuration value based on an enrivonement variables.

For example, if you don't want to store your database password in the configuration file, you can do this:

db_config:
  type:     mysql
  user:     database_user
  password: ${DB_PASSWORD}
  db_name:  db_name
  host:     192.168.0.2
  port:     3306

And export the environment variable such as:

export DB_PASSWORD="<db_password>"

danger

Note: you need to be root or put the environment variable in /etc/environment
