Test and build

Run the following commands:

virtualenv -p "$(which python3)" ./venv
source ./venv/bin/activate
pip install -r dev_requirements.txt
tox
hatch clean
hatch build

Installation

In the absence of OS packages, some more steps are required. See the provided install.sh or run it as root (tested on Debian).

You should then configure your applications/services so that the logs are written only to Rsyslog.

If you use Systemd, you could configure it to forward received logs to Rsyslog. Then it would in general only be necessary to configure applications to only log to stdout/stderr so that Systemd handles the output. Configuration example:

/etc/systemd/journald.conf.d/forward_to_syslog.conf

[Journal]
# Keep log data only in memory, but forward journal log to (r)syslog
Storage=volatile
ForwardToSyslog=yes

# Reduce amount of logs stored in RAM somehow
MaxFileSec=1h
MaxRetentionSec=2days

Then: systemctl restart systemd-journald.service
