You can just create new ini files in conf.d.

I use a Dockerfile and define your settings like something like this:

RUN echo 'max_execution_time=240' >> /usr/local/etc/php/conf.d/php.ini \
 && echo 'memory_limit=1G' >> /usr/local/etc/php/conf.d/php.ini

@Nemo64 i don't have php.ini inside the docker how do i do this?

Hi @manzurshaikh ! Thanks for your interest in this project.

By following what @Nemo64 suggested, you actually create a php.ini in your Docker image, even if you didn't have one.

You can actually do a few different things, depending on your use case:

Generate a php.ini at build time

If you're building your own image on top of a chialab/php:whatever image, you can add the instruction suggested by Nemo in your Dockerfile that will write the pieces of configuration in the php.ini file:

FROM chialab/php:whatever

# ...

# Add this part:
RUN echo 'max_execution_time=240' >> /usr/local/etc/php/conf.d/php.ini \
 && echo 'memory_limit=1G' >> /usr/local/etc/php/conf.d/php.ini

Then build your image as usual with docker build -t your/tag:name . and in your image, PHP will be configured to use 1G memory and to last scripts execution for at most 240s.

OR, if you want, you can:

1. create a php.ini in your repository:

   max_execution_time=240
   memory_limit=1G
   

2. add this file at build time:

   FROM chialab/php:whatever
   
   # ...
   
   # Add this part:
   ADD php.ini /usr/local/etc/php/conf.d/php.ini

These two options are absolutely equivalent. I personally find the solution with the external file to be slightly clearer and easier to maintain, but that's a matter of personal taste.

Add a php.ini at runtime

If you don't want or can't create your own image, and you're just running a container with chialab/php:whatever image, you can still add your own configuration at runtime using Docker volumes:

1. Create a php.ini in the computer/server where Docker container is started:

   max_execution_time=240
   memory_limit=1G
   

2. Mount the php.ini as a read-only volume when you start the container:

   $ docker run --name=my-container \
       -v /path/to/php.ini:/usr/local/etc/php/conf.d/php.ini:ro \
       chialab/php:whatever
