Error loading config of additionally installed plugins

[chbusold]

I created a Docker image derived from this to install another plugin using composer and install a custom configuration file like this:

COPY --chown=root:root --chmod=644 authres_status/config.inc.php /var/www/html/plugins/authres_status/config.inc.php

In the logs I see a lot of errors about not being able to load the file:

errors: <de821df1> PHP Error: Failed to load config from /var/www/html/plugins/authres_status/config.inc.php in /var/www/html/program/lib/Roundcube/rcube_plugin.php on line 166 (POST /?_task=settings&_action=refresh)

I checked inside the container to confirm the file exists and is readable for www-data:

Am I missing something obvious?

After I while I found the root cause. When I do install the plugin using composer like this

composer \
      --working-dir=/usr/src/roundcubemail/ \
      --prefer-dist \
      --prefer-stable \
      --update-no-dev \
      --no-interaction \
      --optimize-autoloader \
      require \
          pimlie/authres_status:* \
    ; \

it creates an empty default config in /usr/src/roundcubemail/plugins/authres_status/config.inc.php, which then overwrites my config when all the stuff is copied into /var/www/html in docker-entrypoint.sh. A workaround is to remove this file after running composer.
However, in general the image seems to be confused at preexisting plugin config files in /var/www/html, causing the 10s startup delay. A better solution may be to provide a way to inject plugin configs during docker-entrypoint.sh. Or should plugin configs be provided in /var/roundcube/config?

There's a convention that plugin configs are searched in Roundcube's config folder named the same as the plugin (e.g. authres_status.inc.php). If you want to include the config right in your Docker image, COPY the file into /usr/src/roundcubemail/config and it should be copied into the right location when the container starts.

The /var/roundcube/config volume is meant to hold configs that are injected into the container and need to be configured for each deployment.

Hi

A little thing I dont yet understand in the README:

Using working-dir=/usr/src/roundcubemail put plugins un vendor, example with kolab/calendar, wich is not found after a brand new startup of an image 🤔

FROM roundcube/roundcubemail:latest-fpm-alpine

RUN set -ex; \
    yes | composer \
        --working-dir=/usr/src/roundcubemail/ \
        --prefer-dist \
        --prefer-stable \
        --update-no-dev \
        --no-interaction \
        --optimize-autoloader \
        require \
            guzzlehttp/guzzle \
            johndoh/globaladdressbook \
            kolab/calendar \
            kolab/tasklist \
            syncgw/roundcube_plugin \
    ;

COPY ["/plugins/calendar/config.inc.php", "/usr/src/roundcubemail/config/calendar/config.inc.php"]

COPY ["/plugins/tasklist/config.inc.php", "/usr/src/roundcubemail/config/tasklist/config.inc.php"]

COPY ["/plugins/libkolab/libokolab.min.css", "/usr/src/roundcubemail/config/libkolab/skins/elastic/libokolab.min.css"]`

With the default roundcube/roundcubemail image, using inside a composer require put theme in plugins folder... And then works.

Thanks a lot for any explanation 🙂
