<br>
You should log everything to the container's stdout instead.<br>
<br>
We use the following Logback configuration in our containers to log everything to the console (i.e. stdout).<br>
With this configuration, the IdP's logs are available via the container's logs (e.g. "docker logs <container>").<br>
(We start the containers with the "journald" log driver, such that all logs from the container<br>
are sent to the host's jornald.)<br>

(You need to ensure that the "idp.*.appender" properties are not set<br>
or set to "CONSOLE".)<br>
