# rsyslog/rsyslog-minimal

A lean Ubuntu-based image containing the rsyslog core and a tiny configuration that writes logs to standard output. It serves as the foundation for the other rsyslog images and is suitable when you want to add your own modules or configuration.

## Environment Variables

The entrypoint script recognizes the following variables:

RSYSLOG_HOSTNAME

  Hostname used inside rsyslog. Defaults to the value of `/etc/hostname` when unset.

PERMIT_UNCLEAN_START

  Skip configuration validation when set. By default `rsyslogd -N1` validates the configuration.

RSYSLOG_ROLE

  Role name consumed by the entrypoint. Defaults to `minimal` and normally does not need to be changed.
