Adding imagick to my docker LAMP I got error :You should add “extension=imagick.so” to php.ini

how did you install apache2 and php?

please always do : sudo apt update

before you install any app then sudo apt install your-app

if you have a fresh new linux system you can sudo apt install apache2 php

remember after installed php , you have to manually install some php extensions after all these then sudo apt install imagick

actually , linux is smart enough to add config to your server and php.ini

Try this instead (instead of that one line)

ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/

RUN chmod uga+x /usr/local/bin/install-php-extensions && sync && \
    install-php-extensions imagick

I am not sure which must be modifications. I modified my Dockerfile.yml as :

FROM php:7.3-apache

RUN apt-get update && \
    apt-get install -y \
    python \
    libfreetype6-dev \
    libwebp-dev \

    libpng-dev \
    libzip-dev \
    nano \
    mc \
    git-core \

   # I LEFT THESE 3 LINES

  # THESE 2 LINES ADDES

    ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/

    RUN chmod uga+x /usr/local/bin/install-php-extensions && sync && \
    install-php-extensions imagick
    
COPY virtualhost.conf /etc/apache2/sites-enabled/000-default.conf

But I got error anyway :

Build process completed successfully

?

You might need to use one of the php.ini files as well

RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"

I modified docker file:

  ...

  RUN  docker-php-ext-install gd pdo pdo_mysql zip gmp bcmath pcntl ldap sysvmsg exif  \
&& a2enmod rewrite

  # ADDED THIS LINE

    RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"

    ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/

    RUN chmod uga+x /usr/local/bin/install-php-extensions && sync && \
    install-php-extensions imagick
  
    
COPY virtualhost.conf /etc/apache2/sites-enabled/000-default.conf

but got error :

Ok then try adding it manually

RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"

RUN echo "extension=imagick.so" >> "$PHP_INI_DIR/php.ini" \

I added the line in /Dockerfile.yml :

  RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

  RUN  docker-php-ext-install gd pdo pdo_mysql zip gmp bcmath pcntl ldap sysvmsg exif  \
&& a2enmod rewrite


    RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"

    RUN echo "extension=imagick.so" >> "$PHP_INI_DIR/php.ini" \

    ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/

    RUN chmod uga+x /usr/local/bin/install-php-extensions && sync && \
    install-php-extensions imagick
  
    
COPY virtualhost.conf /etc/apache2/sites-enabled/000-default.conf

and still got error :

zip-dev     nano     mc     git-core  

Also I have virtualhost.conf included, with content :

1. can it be that this file overwrites “extension=imagick.so” option we prepare in our command?
2. Can I add extension=imagick.so option in this file ?
