Disabling apcu and opcache for local development?

[freiondrej-lmc]

Hello,
I'm using symfony-docker to simplify my local development (great job, it's amazing!).
I mounted the work dir into the php container as a volume - .:/srv/app, but the changes I did to my local files did not take effect when running php. I tried adding opcache_reset() and apcu_clear_cache() to public/index.php, but it did not help. Then I tried disabling opcache and apcu by commenting out the Dockerfile part with docker-php-ext-enable apcu opcache; and it indeed solved the problem. However doing it like this felt a bit cumbersome and made me think I'm probably doing something wrong, but I did not find anything about this in the README nor the docs/. What is the best way to do this?

Thank you! 🙂

Thanks a lot for this, I couldn't understand why the code was updating in the container but the changes were not reflected in the browser. I don't if there's another way to disable the cache though.

You can try disabling the opcache via environment variables or via php-ini-overrides.ini. Try putting this into your docker-compose file, in the PHP section:

environment:
      PHP_OPCACHE_VALIDATE_TIMESTAMPS: "1"
      PHP_OPCACHE_PRELOAD: ""

Or if you prefer the ini method:
php-ini-overrides.ini

opcache.enable=0

docker-compose.yaml

  php:
    volumes:
      - ./path-to-your/config-directory/php-ini-overrides.ini:/etc/php/7.4/fpm/conf.d/99-overrides.ini

This should not affect your production setup.

@cizordj great, thanks! How did you know that? Was that somewhere in the documentation, where I missed it, or are you an advanced user?

[cizordj]

No, I'm just an average programmer, I had this problem right now and I asked for help to my devops leader.

[freiondrej-lmc]

@cizordj I see :) Is it okay with you if I use your example in a new issue so that this can be added to the documentation for everybody?

[cizordj]

@freiondrej-lmc no problem for me.
