add support for oauth in docker image

Fix grosjo/nextcloud-grauphel#55

That looks like the wrong way to add a new php extension. Please check: https://github.com/docker-library/docs/blob/master/php/README.md#how-to-install-more-php-extensions

[monperrus]

Thanks a lot for the pointer, fixed.

[kesselb]

Still looks wrong. Afaik apt-get is not the right way to install a php package.

[monperrus]

thanks for the feedback.

unclear to me whether oauth should be installed with docker-php-ext-enable or PECL/docker-php-ext-enable.

Here is a WIP version full PECL, WDYT?

Since this is not required by default apps I'd prefer moving this to our examples: https://github.com/nextcloud/docker/tree/master/.examples#dockerfiles

We really want to use grauphel but it's more important for us to depend on the official Docker image of Nextcloud.

So if we don't merge this feature, it's basically a NO-GO for grauphel and all plugins depending on oauth.

[monperrus]

Here is how to activate oauth for grauphel.

Works for me in a Docker container running Nextcloud 23:

apt install libpcre3-dev
pecl install oauth
echo extension=oauth.so > /usr/local/etc/php/conf.d/oauth.ini
service apache2 restart

Unfortunately we can't include every extension by default. The requirements for Nextcloud itself are listed in https://docs.nextcloud.com/server/latest/admin_manual/installation/source_installation.html#prerequisites-for-manual-installation
Custom apps and other custom requirements can be installed using hooks (as proposed in #820) or by building a child image.

Closing in favour of #1964.
