Docker-php-ext-install mcrypt missing folder

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:

error: /usr/src/php/ext/mcrypt does not exist


usage: /usr/local/bin/docker-php-ext-install [-jN] ext-name [ext-name ...]

   ie: /usr/local/bin/docker-php-ext-install gd mysqli
   /usr/local/bin/docker-php-ext-install pdo pdo_mysql
   /usr/local/bin/docker-php-ext-install -j5 gd mbstring mysqli pdo pdo_mysql shmop

if custom ./configure arguments are necessary, see docker-php-ext-configure

Possible values for ext-name:
bcmath bz2 calendar ctype curl dba dom enchant exif fileinfo filter ftp  gd gettext gmp hash iconv imap interbase intl json ldap mbstring mysqli oci8  odbc opcache pcntl pdo pdo_dblib pdo_firebird pdo_mysql pdo_oci pdo_odbc pdo_pgsql pdo_sqlite pgsql phar posix pspell readline recode reflection session shmop simplexml snmp soap sockets sodium spl standard sysvmsg sysvsem sysvshm tidy tokenizer wddx xml xmlreader xmlrpc xmlwriter xsl zend_test zip

Some of the above modules are already compiled into PHP; please check
the output of "php -i" to see which modules are already loaded.
ERROR: Service 'web' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y          libfreetype6-dev          libjpeg62-turbo-dev          libmcrypt-dev          libpng-dev     && docker-php-ext-install -j$(nproc) iconv mcrypt gd mbstring zip' returned a non-zero code: 1

My Dockerfile:

FROM php:7.2-apache

RUN apt-get update && apt-get install -y \
     libfreetype6-dev \
     libjpeg62-turbo-dev \
     libmcrypt-dev \
     libpng-dev \
&& docker-php-ext-install -j$(nproc) iconv mcrypt gd mbstring zip
#    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
#    && docker-php-ext-install -j$(nproc) gd


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

EXPOSE 80

Has anybody an idea how to solve or how to get the needed files in the requested folder?

Thanks!

Solution 1

mcrypt extension is not provided with the PHP source since 7.2 , but are instead available through PECL. To install a PECL extension in docker, use pecl install to download and compile it, then use docker-php-ext-enable to enable it:

pecl install mcrypt-1.0.4
docker-php-ext-enable mcrypt

Before the pecl install you may need to install/update the package libmcrypt-dev

apt-get update && apt-get install -y libmcrypt-dev

Solution 2

Building on MoiioM's answer, this worked for me using the 7.2-stretch Docker image from PHP

RUN apt-get update && apt-get install -y libmcrypt-dev \
    && pecl install mcrypt-1.0.4 \
    && docker-php-ext-enable mcrypt

Solution 3

To install mcrypt extension you have to make sure you did install libmcrypt-dev which is required.

Try to add:

RUN apt install libmcrypt-dev

before you are trying to install extensions for php.

Update

Try to run first:

docker-php-ext-configure mcrypt

and then

docker-php-ext-install mcrypt

It is best not to use PHP mcrypt, it is abandonware, has not been updated in years and does not support standard PKCS#7 (née PKCS#5) padding, only non-standard null padding that can't even be used with binary data. mcrypt has many outstanding bugs dating back to 2003. The mcrypt-extension is deprecated will be removed in PHP 7.2. Instead consider using defuse or RNCryptor, they provide a complete solution and are being maintained and is correct.

[Gerrit]

I use that command in my Dockerfile but it is not working. I added it to my post.

[Hans]

FYI, I had to remove mcrypt from the line where it was trying to install it, as well as add the text in this question. After that, it all seemed to work.

[tim]

@Hans, do you mean apt-get remove mcrypt to remove it?

[Ary Wibowo]

not work either. it says "Possible values for ext-name: bcmath bz2 calendar ctype curl dba dom enchant exif fileinfo filter ftp gd gettext gmp hash iconv imap interbase intl json ldap mbstring mysqli oci8 odbc opcache pcntl pdo pdo_dblib pdo_firebird pdo_mysql pdo_oci pdo_odbc pdo_pgsql pdo_sqlite pgsql phar posix pspell readline recode reflection session shmop simplexml snmp soap sockets sodium spl standard sysvmsg sysvsem sysvshm tidy tokenizer wddx xml xmlreader xmlrpc xmlwriter xsl zend_test zip"

[Yehia]

you need to install libmcrypt-dev package first

[ToolmakerSteve]

@tim - no, Hans means that his line docker-php-ext-install -j$(nproc) iconv mcrypt ... needs to have mcrypt removed; mcrypt can't be installed via docker-php-ext-install (because mcrypt is no longer available as a normal extension). pecl install mcrypt-1.0.2 is the command to use now. To make mcrypt available for use, also do enable, as shown in this answer.

[Lano]

And if you want to use it with PHP 7.4, you need to use mcrypt-1.0.3.

error: /usr/src/php/ext/libmcrypt-dev does not exist

[Fariman Kashani]

I get error: mcrypt.h not found. Please reinstall libmcrypt.

[MoiioM]

You may need to update libmcrypt-dev package
