mcrypt Extension not loaded although installed

[cbeier]

I use the standard composer/composer build. It seems that the extension is installed and loaded. But in the phpinfo() the extension is not loaded / listed.

So if I install laravel via my composer container I get a error that the mcrypt extension is missing.

Output php -m:

Interesting. Does a follow-up php5enmod mcrypt do anything?

[cbeier]

No, that does nothing.

I think the problem comes from the base php:5.6-cli image. If I build a Dockerfile from scratch, then the mcrypt extension is loaded.

Dockerfile:

FROM debian:jessie

RUN apt-get update -y
RUN apt-get install -y php5-cli php5-dev php5-json curl git-core
RUN apt-get install -y zlib1g zlib1g-dev php5-common mcrypt
RUN apt-get install -y php5-curl php5-mcrypt php5-readline php-pear

RUN php5enmod curl json readline mcrypt pdo
RUN pecl install zip

# Set memory limit.
RUN echo "memory_limit=1024M" > /etc/php5/cli/conf.d/memory-limit.ini

RUN curl -sS https://getcomposer.org/installer | php

# Set up the command arguments
CMD ["-"]
ENTRYPOINT ["/composer.phar", "--ansi"]

Think we should ditch php:5.6-cli?

[cbeier]

Unfortunately, I do not know exactly what causing the problem inside the php image. But inside the php:5.6-cli image are some things adjusted (paths, compile options, ...) which deviate from the standard PHP installation on Debian.

[RobLoach]

@cbeier Is there another PHP-CLI Docker Container that you would recommend we use?

[cbeier]

@RobLoach I have forked the container from ubermuda and customized (added necessary php extensions). My fork on github: https://github.com/cbeier/docker-composer and on docker: https://registry.hub.docker.com/u/cbeier/composer/

I currently know of no other php-cli container. Most container include php-cli with the used command line app.

[boedy]

I have the same problem with mcrypt. Now using your fork @cbeier .

[RobLoach]

Opened up a PR for this: #18

[boedy]

I think you should have used docker-php-ext-install for mcrypt

Something like this works for me (I probably also install some libraries which you don't need though. these you can leave out):

FROM php:5.6-cli

Hi,

I've similar issue with the mbstring extension see details here : https://bugs.php.net/bug.php?id=71181

[sylus]

I can't reproduce this anymore on a recent docker pull is this issue still present?

[RobLoach]

Going to close this for now. Feel free to open up a new issue if it persists.
