memcached php extension broken in wordpress 21.0.0 to 21.0.3

[fabio-peptone]

Name and Version

bitnami/wordpress 21.0.3

What architecture are you using?

amd64

What steps will reproduce the bug?

Install chart 21.0.3 with

wordpressConfigureCache: true

memcached:
  enabled: true

The memcached plugin is not enabled in php.

Execing into the wordpress container

$ $ grep memcache /opt/bitnami/php/etc/php.ini
;extension = memcached

The extension is correctly enabled in chart 20.1.3

What is the expected behavior?

memcached php extension should be enabled

What do you see instead?

memcached php extension is not enabled

Additional information

I believe this was broken in 38bf03c. As far as I understand, php extensions are enabled during container build. Replacing php/etc with an emptydir removes all the build-time configuration

A workaround that worked for me is to define a post-init script which uncomments the extension in php.ini:

# Enable memcached plugin in php.ini
# https://github.com/bitnami/charts/issues/24605
customPostInitScripts:
  enable_php_ini_memcached.sh: |
    #!/bin/bash
    sed -i 's/^;extension = memcached$/extension = memcached/' /opt/bitnami/php/etc/php.ini
