I have built a docker container containing renderd and apache2 to render tiles from a postgis database (inside another container).
This works fine, however, renderd is not producing log output after:
** INFO: 17:20:22.021: Running in foreground mode...
** INFO: 17:20:22.021: Loading parameterization function for

2021-11-29 17:20:22,021 DEBG 'renderd' stdout output:

I am using supervisord to run both processes inside a single container.

stderr_logfile = /var/log/supervisor/apache-stderr.log
stdout_logfile = /var/log/supervisor/apache-stdout.log
[program:renderd]
command=/usr/bin/renderd -f
stderr_logfile = /var/log/supervisor/renderd-stderr.log
#stdout_logfile = /var/log/supervisor/renderd-stdout.log
stdout_logfile=/dev/fd/1
stdout_logfile_maxbytes=0
I'm redirecting stdout of renderd to stdout of the container to see the output with "docker logs " command. Furthermore, I have set the log level to info to not miss anything. Running on a bare metal server, renderd produces log entries that can be read out with journalctl for incoming requests. I would like to access these logs.
I made it working by adding the following to my dockerfile:
ENV G_MESSAGES_DEBUG=all
