Php: How do I disable apache logging?

[aarhusgregersen]

Heya!

Using the following setup for PHP Apache:

FROM php:7.1-apache

# install the PHP extensions we need
RUN set -ex; \
    \
    apt-get update; \
    apt-get install -y \
    libjpeg-dev \
    libpng-dev \
    ; \
    rm -rf /var/lib/apt/lists/*; \
    \
    docker-php-ext-configure gd --with-png-dir=/usr --with-jpeg-dir=/usr; \
    docker-php-ext-install gd mysqli opcache

# set recommended PHP.ini settings
# see https://secure.php.net/manual/en/opcache.installation.php
RUN { \
    echo 'opcache.memory_consumption=128'; \
    echo 'opcache.interned_strings_buffer=8'; \
    echo 'opcache.max_accelerated_files=4000'; \
    echo 'opcache.revalidate_freq=2'; \
    echo 'opcache.fast_shutdown=1'; \
    echo 'opcache.enable_cli=1'; \
    } > /usr/local/etc/php/conf.d/opcache-recommended.ini

# Sets custom PHP.ini for error logging
RUN { \
    touch /usr/local/etc/php/php.ini; \
    echo "log_errors = On"; \
    echo "error_log = /dev/stderr" \
    echo "error_reporting = E_ALL"; \
} > /usr/local/etc/php/php.ini

RUN a2enmod rewrite expires

CMD ["apache2-foreground"]

I get a lot of HTTP logging (from apache I suppose) by default in the docker window.

Is there a way to disable this?
As you can tell I have also enabled error logging by writing to php.ini, which is working just fine.
But the php logging is hard to spot between the apache logging, so I want to disable it.

I would've added a question label but it seems I am unable to do so.

The reason for the chatter is that in /var/log/apache2, you have the following symlink:

lrwxrwxrwx 1 root root 11 Dec 1 01:48 access.log -> /dev/stdout

and stdout is piped to the Docker logs by default. Since that's behavior you want, you should change the apache logs destination in your Dockerfile by either:

A) Delete the access.log symlink and recreate it as a normal file.
-or-
B) Edit the various confs, similar to the solution here (https://github.com/docker-library/php/issues/246#issuecomment-328215790) and point the logs somewhere else.

for reference on tactic B:

/etc/apache2# grep -Ri access.log
[unrelated stuff]
sites-available/default-ssl.conf:       CustomLog ${APACHE_LOG_DIR}/access.log combined
sites-available/000-default.conf:   CustomLog ${APACHE_LOG_DIR}/access.log combined
sites-enabled/000-default.conf: CustomLog ${APACHE_LOG_DIR}/access.log combined

Thanks @qedrakmar !

I just added RUN rm /var/log/apache2/access.log to my Dockerfile which fixed it - thanks :)
