Add custom extension

[marcteyssier]

I use the image thecodingmachine/php:7.2-v2-apache (the 7.3 is not on docker hub), and I want to add a custom extension in php. I have a .so, but how can I add automatically in the extension directory and enable it ?

I found the extension directory but the name is /usr/local/lib/php/extensions/no-debug-non-zts-20170718/ and I don't know how can I automatically get it.

Is it possible to add easily a custom .so extension ?

7.3-v2-apache is on Docker hub!

The extensions directory is not likely to change if you don't change the version of PHP.
So you can assume it will always be the same directory and add the extension in this directory using a Dockerfile.

Out of curiosity, what extension are you trying to install? Does it deserve being added in thecodingmachine/php or is it specific?

Also, on a side note, you can find automatically the extensions directory by calling: pecl config-get ext_dir
