How to fix Docker "/usr/src/php/ext/mcrypt does not exist" build error?

Question

I try to install mcrypt in my docker image based on php:7.2-apache. Therefore I use the RUN-Command from the documentation and also answerd here but I receive this error. I think maybe while setup may be missing.

This is my app.docker file.

    FROM php:7-fpm

# Install any custom system requirements here
RUN apt-get update \
  && apt-get install -y --no-install-recommends \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libpng-dev \
    curl \
    vim \
    cron \
    procps \
    zlib1g-dev \
    zip

RUN apt-get update && apt-get install -y libmcrypt-dev mysql-client \
    && docker-php-ext-install pdo_mysql \
    && docker-php-ext-install -j$(nproc) iconv mcrypt \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd \
    && docker-php-ext-install zip \
    && docker-php-ext-install bcmath \
    && curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

WORKDIR /var/www

report error in when build docker.

Even though the path to the is specified in Dockerfile, it says not found

Anyone know why?

This is because mcrypt is deprecated after php:7.1. You can use a base image which still supports mcrypt eg php:5.6-cli or use an alternative to mcrypt.

Well whats an alternative?

@Octavian That kinda depends on why you need mcrypt in the first place. If it's a library you're using, it may need an updated version (like going from Laravel 4 to 5). If it's your own code, the replacement is php.net/manual/en/function.openssl-encrypt.php.

This worked for me, copied from here:

RUN apt-get update && apt-get install -y libmcrypt-dev \
    && pecl install mcrypt-1.0.2 \
    && docker-php-ext-enable mcrypt
