Why?

The PHP process may not be able to write to the /var/log directory.  Assuming it's the apache user that php is running as in this case.  Connect to the container and check out the perms for /var/log.

Why did you change the error log path at all? The php:apache image should have set everything up for you already.

$ chown www-data:www-data /var/log/error.log

Solved!!!
