install Gd extension on docker

Question

I triedto install gd extension on docker but it doesn't worked,I found some examples many with php-fm, but its not working with the image that I used,this is my dockerfile :

FROM php:7.4.2-apache

RUN pecl install xdebug && docker-php-ext-enable xdebug && docker-php-ext-install mysqli pdo pdo_mysql && docker-php-ext-enable pdo_mysql && pecl install apcu && docker-php-ext-enable apcu \
# not yet in linux: xdebug.remote_host = host.docker.internal \n\
&& echo "\n\
xdebug.mode = debug \n\
xdebug.start_with_request = yes \n\
xdebug.client_port = 9003 \n\
xdebug.client_host = 172.18.0.1 \n\
xdebug.log = "C:\xdebug_log\xdebug.log" \n\
xdebug.idekey = VSCODE \n\
" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

RUN apt-get update \
    && apt-get -y --no-install-recommends install libfontconfig1 libxrender1 libxext6  \
    && apt-get clean; rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

RUN cd /usr/local/etc/php/conf.d/ && \
  echo 'memory_limit = -1' >> /usr/local/etc/php/conf.d/docker-php-memlimit.ini

RUN docker-php-ext-install opcache && docker-php-ext-enable opcache

UPDATE:

I made some changes  , then  my dockerfile is 

FROM php:7.4.2-apache

RUN pecl install xdebug && docker-php-ext-enable xdebug && docker-php-ext-install mysqli pdo pdo_mysql && docker-php-ext-enable pdo_mysql && pecl install apcu && docker-php-ext-enable apcu \
# not yet in linux: xdebug.remote_host = host.docker.internal \n\
&& echo "\n\
xdebug.mode = debug \n\
xdebug.start_with_request = yes \n\
xdebug.client_port = 9003 \n\
xdebug.client_host = 172.18.0.1 \n\
xdebug.log = "C:\xdebug_log\xdebug.log" \n\
xdebug.idekey = VSCODE \n\
" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

RUN apt-get update \
    && apt-get -y --no-install-recommends install libfontconfig1 libxrender1 libxext6  \
    && apt-get clean; rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

RUN cd /usr/local/etc/php/conf.d/ && \
  echo 'memory_limit = -1' >> /usr/local/etc/php/conf.d/docker-php-memlimit.ini

RUN docker-php-ext-install opcache && docker-php-ext-enable opcache

RUN apt-get install -y \
        libzip-dev \
        zip \
  && docker-php-ext-install zip

# GD
RUN docker-php-ext-configure gd --with-freetype --with-jpeg \
  && docker-php-ext-install -j "$(nproc)" gd

COPY 000-default.conf /etc/apache2/sites-available/000-default.conf
    
    RUN apt-get update && apt-get install -y \
            libfreetype6-dev \
            libjpeg62-turbo-dev \
            libpng-dev \
        && docker-php-ext-install -j$(nproc) iconv \
        && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
        && docker-php-ext-install -j$(nproc) gd
    
    COPY 000-default.conf /etc/apache2/sites-available/000-default.conf

and I get this error:

    configure: error: unrecognized options: --with-freetype-dir, --with-jpeg-dir
    ERROR: Service 'apache_with_php' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y         libfreetype6-dev         libjpeg62-turbo-dev         libpng-dev     && docker-php-ext-install -j$(nproc) iconv     && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/     && docker-php-ext-install -j$(nproc) gd' returned a non-zero code: 1

I trid to install zlib, because It warns that cannot found it, the I tri to instal zlib and gd, but I get

Building dependency tree...
Reading state information...
E: Unable to locate package libzip-dev
E: Unable to locate package zip
ERROR: Service 'apache_with_php' failed to build: The command '/bin/sh -c apt-get install -y         libzip-dev         zip   && docker-php-ext-install zip' returned a non-zero code: 100

UPDATE 2:

I made some changes in my dockerfile:

FROM php:7.4.2-apache

RUN pecl install xdebug && docker-php-ext-enable xdebug && docker-php-ext-install mysqli pdo pdo_mysql && docker-php-ext-enable pdo_mysql && pecl install apcu && docker-php-ext-enable apcu \
# not yet in linux: xdebug.remote_host = host.docker.internal \n\
&& echo "\n\
xdebug.mode = debug \n\
xdebug.start_with_request = yes \n\
xdebug.client_port = 9003 \n\
xdebug.client_host = 172.18.0.1 \n\
xdebug.log = "C:\xdebug_log\xdebug.log" \n\
xdebug.idekey = VSCODE \n\
" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

RUN apt-get update \
    && apt-get -y --no-install-recommends install libfontconfig1 libxrender1 libxext6  \
    && apt-get clean

RUN cd /usr/local/etc/php/conf.d/ && \
  echo 'memory_limit = -1' >> /usr/local/etc/php/conf.d/docker-php-memlimit.ini

RUN docker-php-ext-install opcache && docker-php-ext-enable opcache

RUN apt update && apt install -y zlib1g-dev libpng-dev
RUN docker-php-ext-install gd && docker-php-ext-enable gd

#RUN rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

COPY 000-default.conf /etc/apache2/sites-available/000-default.conf

now there is no error on build, but I get this message:

warning: gd (gd.so) is already loaded!

and when I check the phpinfo() gd is not on the extension list

As mentioned in the comments above, your dependencies should be installed in a RUN , if you delete /var/lib/apt/lists , you will have to run an apt-get update again and again afterwards to make sure the data is there, otherwise you will not be able to install anything via apt-get install .

FROM php:7.4.2-apache
RUN apt-get update \
    && apt-get -y --no-install-recommends install libfontconfig1 libxrender1 libxext6 zlib1g-dev libpng-dev libfreetype6-dev libjpeg62-turbo-dev \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* 

RUN pecl install xdebug && docker-php-ext-enable xdebug && docker-php-ext-install mysqli pdo pdo_mysql && docker-php-ext-enable pdo_mysql && pecl install apcu && docker-php-ext-enable apcu \
# not yet in linux: xdebug.remote_host = host.docker.internal \n\
&& echo "\n\
xdebug.mode = debug \n\
xdebug.start_with_request = yes \n\
xdebug.client_port = 9003 \n\
xdebug.client_host = 172.18.0.1 \n\
xdebug.log = "C:\xdebug_log\xdebug.log" \n\
xdebug.idekey = VSCODE \n\
