How can I override ddev's php-fpm.conf or pool.d/www.conf?

问题

There is no obvious way to override some php-fpm configuration in DDEV-Local's web container. Although it's easy to provide custom PHP configuration it's not as obvious how one would configure the php-fpm process itself.

In my case I want to change the security.limit-extensions value in pool.d/www.conf

There are two ways to do this. I'll create two separate answers to explain how.

The first technique is to create a custom Dockerfile (docs) which edits the www.conf (or any other file). You can also use the Dockerfile ADD command to add a complete file and override them.

In the case of this specific problem, we'll create a .ddev/web-build/Dockerfile with these contents:

# You can copy this Dockerfile.example to Dockerfile to add configuration
# or packages or anything else to your webimage
ARG BASE_IMAGE
FROM $BASE_IMAGE
ENV PHP_VERSION=7.4
RUN echo "security.limit_extensions = .php .html" >> /etc/php/${PHP_VERSION}/fpm/pool.d/www.conf

After you ddev start you'll have the new configuration.

Instead of the RUN echo approach that just appends to the file, given here for simplicity, you could RUN a sed/awk/perl statement to change the file in place.

And alternatively you could put the version of the www.conf that you want into the .ddev/web-build directory and

COPY www.conf /etc/php/${PHP_VERSION}/fpm/pool.d/www.conf

The second way to approach this is to use a custom docker-compose.*.yaml file (docs.

Here you'll copy the desired www.conf (or any other file) into your project's .ddev directory and then mount it into the web container on top of the previously provided one. For this specific example, you can copy the www.conf into the .ddev folder by cd .ddev && docker cp ddev-<projectname>-web:/etc/php/7.4/fpm/pool.d/www.conf . and edit it as you need to (edit it with "security.limit_extensions = .php .html").

Then a custom .ddev/docker-compose.*.yaml file like this can mount it into the proper directory (mine is called docker-compose.wwwconf.yaml):

version: "3.6"
services:
  web:
    volumes:
    - "./www.conf:/etc/php/7.4/fpm/pool.d/www.conf"
