Changes on httpd without reload

[Maleksafi]

I have apache -php on docker container and it has bind mount volume, when updating files inside mount volume it's reflected in the container , but the apache does not see these changes unless reloaded apache,

i want to see these changes on httpd without reload ,is this possible ?

Thanks

Unfortunately, I'm not actually able to reproduce: 😅

$ echo '<?php echo "foo\n";' > index.php
$ docker run -dit --name foo --mount type=bind,src="$PWD",dst=/var/www/html,ro --pull=always php:apache
apache: Pulling from library/php
Digest: sha256:7852b16fb672b5ae8acc4a0e3120152fa281e40f0b182aff4a192c5537d966d9

$ docker exec foo curl -fsSL localhost
foo
$ echo '<?php echo "bar\n";' > index.php
$ docker exec foo curl -fsSL localhost
bar

Perhaps you've got some over-aggressive cache enabled? (PHP's own opcache, perhaps?)

(Edit: updated with the command I used to change index.php 😭)

Can you find my Dockerfile

FROM php:8.1.24-apache
# Update and install dependencies
RUN apt-get update && apt-get --no-install-recommends  install -y \
    apache2-utils \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libmcrypt-dev 
 
COPY ./php.ini /usr/local/etc/php/php.ini
RUN a2enmod vhost_alias mpm_prefork rewrite php alias autoindex

docker-compose.yml

version: '3'
services:
  docker:
    image: docker_httpd
    ports:
      - 80:80
    volumes:
      - /app:/app
      -  ./apache2.conf:/etc/apache2/apache2.conf
      - ./httpd-vhosts.conf:/etc/apache2/sites-enabled/httpd-vhosts.conf

/app had my PHP code,
can try with PHP projects, have multiple files like Yii or Laravel app?
I disabled opcache on php
Any suggest?

Doing a2enmod on php is definitely odd, but not likely to cause the problem you've described.

Without more details about your php.ini and your Apache configuration, it's really hard to say though, because those are definitely going to be what's at fault for overaggressive cache here.

Maybe you could work to create a more minimal reproducer? (Remove bits from your custom php.ini, remove bits from your custom Apache config, etc until the problem no longer reproduces.)

@tianon
Thank you for your reponse
The issue was fixed by disabling opcache ext on php.ini

opcache.enable=0

and i move php.ini to docker compose instead of docker file and it was working fine.
Thank you

Excellent, glad you got it figured out!
