Can't enable Docker Xdebug - docker

I am trying to use Xdebug on Docker, I'm using Debian, PHP 8. Cannot make a connection with Xdebug. Won't give any errors.
Since I don't get any errors or logs can't figure out what is wrong with my configurations.
Everything builds normally with the configurations below. Could someone help me activate Xdebug?

Enable/Disable xDebug through Docker-Compose, is it possible?

I have the following Dockerfile:
FROM php:7.2-apache
RUN apt-get update && apt-get install -y \
zlib1g-dev \
git \
unzip \
&& rm -rf /var/lib/apt/lists/ \
&& docker-php-ext-install zip pdo_mysql bcmath \
&& a2enmod rewrite \
&& pecl install xdebug-2.9.0 redis \
&& docker-php-ext-enable xdebug redis \
&& mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini" \
&& mv /var/www/html /var/www \
&& chown -R www-data:www-data /var/www/ \
&& ln -s /usr/local/bin/php /usr/bin/php
COPY --from=composer:1.9 /usr/bin/composer /usr/bin/composer
WORKDIR /var/www/drm-case
CMD ["docker/apache/bootstrap.sh"]
And this is the docker-compose.yml file that uses the previous Dockerfile to build the containers (not all the time though):
version: "2.4"
services:
case-v2-apache:
container_name: local-dev
image: local-dev:1.6 # increase this number when changing the Dockerfile
depends_on:
mysql-server:
condition: service_healthy
volumes:

- ${LOCAL_PATH}/docker/apache/sites-available/000-default.conf:/etc/apache2/sites-available/000-default.conf
ports:
- "8009:80"
logging:
driver: "json-file"
options:
max-size: "10m"
max-file: "3"
build:
context: ${LOCAL_PATH:-./local-dev}
dockerfile: docker/apache/Dockerfile
networks:
- main
environment:
- VIRTUAL_HOST=local-dev.localhost
- COMPOSER_MEMORY_LIMIT=-1
- COMPOSER_AUTH=${COMPOSER_AUTH}
- COMPOSER_ALLOW_SUPERUSER=1
- PHP_IDE_CONFIG=serverName=local-dev
One of the files being copied in this line: ${LOCAL_PATH}/docker/apache/conf.d:/usr/local/etc/php/conf.d is xdebug related meaning is the one enabling and setting up the extension.
Wonder if there is a way to tell Docker by using ARG or ENV variables to enable/disable xDebug while starting the container? Has anyone tried such thing before? If so can you help me with some ideas?
You could simply move/rename the xdebug conf file based on a build arg…
FROM php:7.2-apache
RUN apt-get update && apt-get install -y \
zlib1g-dev \
git \
unzip \
&& rm -rf /var/lib/apt/lists/ \
&& docker-php-ext-install zip pdo_mysql bcmath \
&& a2enmod rewrite \
&& pecl install xdebug-2.9.0 redis \
&& docker-php-ext-enable xdebug redis \
&& mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini" \
&& mv /var/www/html /var/www \
&& chown -R www-data:www-data /var/www/ \
&& ln -s /usr/local/bin/php /usr/bin/php
COPY --from=composer:1.9 /usr/bin/composer /usr/bin/composer
RUN if [[ "$DISABLE_XDEBUG" == "1" ]] ; then mv "$PHP_INI_DIR/conf.d/xdebug.ini" "$PHP_INI_DIR/conf.d/xdebug.ini.disabled"
WORKDIR /var/www/drm-case
CMD ["docker/apache/bootstrap.sh"]
… or something like that?

composer install with prestissimo in docker container

I can try composer install in docker container on ubuntu16.04 image with hirak/prestissimo plugin.
FROM ubuntu:16.04
RUN apt-get update && apt-get install -y software-properties-common \
&& LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php \

&& apt-get install -y php7.1 git vim supervisor curl unzip mysql-client wget \

RUN composer --no-interaction global require 'hirak/prestissimo'
COPY docker/config/ /config/
RUN cp /config/supervisord.conf /etc/supervisor/supervisord.conf

And my docker-compose.yml file
version: '3'
services:
php71:

image: mylogin/myimage
volumes:

networks:

But when i run composer-install in my docker container parallel installation with hirak/prestissimo plugin doesn't work.

Ionic serve hot reload with docker not working

I had an ionic app which I have dockerized. The build and up commands are successful and I can access the app at http://localhost:8100. However, hot reload doesn't work. Whenever I edit some file, those changes are nor reflected until redo an ionic serve, but if I rename some file inside the container, the ionic rebuild the app automatically.

Is the problem something I did? or will it be a docker / ionic bug?
I found this on github. you can try to put this in /etc/sysctl.conf

and then reboot or
sudo sysctl --system

When I run docker-compose --verbose up -d I notice that there are no env vars passed in for my php container. I've verified that those env vars are set on my host, and they are passed in for all of my other containers without fail. Anyone have any ideas?
EDIT: Strangely enough, I've also noticed that /proc/$PID/environ (where $PID is the PID of the php container [obtained by running docker inspect --format "{{.State.Pid}}" php] on the host machine is empty.
