On instance of a website requires for one of it's plugins the installation of ioncube

I cant seem to make it work. Is there a way to add ioncube ?

Answer 1

Perhaps it makes sense to Use a custom Docker Image for your Wordpress instance. You can create one based on the wordpress image you already use and than add ioncube to it for example like this:

https://github.com/atsu666/docker-ioncube/blob/master/Dockerfile#L43

Answer 2

In your php.Dockerfile add the following to install ioncube to the php image

    # Install curl
RUN apk --no-cache add curl


# Install IonCube Loader
# Create the IonCube directory
RUN mkdir -p /ioncube

# Download and extract IonCube Loader
RUN curl -o /ioncube/ioncube.tar.gz https://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz \
    && tar xvzf /ioncube/ioncube.tar.gz -C /ioncube \
    && rm /ioncube/ioncube.tar.gz

COPY ioncube/ioncube_loader_lin_7.4.so /ioncube/ioncube_loader_lin_7.4.so

# Update the php.ini file with the Zend extension
RUN echo "zend_extension=/ioncube/ioncube_loader_lin_7.4.so" >> /usr/local/etc/php/php.ini  

Then make sure your server is connected to the php image from up stream in nginx config it looks as follow:

    location ~ \.php$ {
                try_files $uri =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php;
        }

You can confirm ioncube loader has been installed by running a shell command from php container like follow:

docker exec-it <name-of php container> /bin/sh

Then run the php -m command and it should output

[Zend Modules] Zend OPcache the ionCube PHP Loader + ionCube24

An you should also see the ionCube loader in the list of modules.

Remember to replace ioncube_loader_lin_7.x.so" with the version of your php. If you are running php 8.1 use ioncube_loader_lin_8.1.so"

For better results try to have a copy of the ioncube folder containg the file ioncube_loader_lin_8.1.so and also try to run the loader wizard file that comes with ioncube on the browser like:

http://localhost/loader-wizard.php if running on localhost to confirm installation.
