Not clear how to set/get config reliably without example

[icedwater]

Updating the trusted domains using the ownCloud Docker Compose instructions didn't seem to work - the domains were still untrusted even though the list was updated - so I tried editing the config using the provided occ command.

But there were conflicting instructions online on how to do so, so I tried a bunch of alternatives and none of them worked well.

Steps to reproduce

1. Enter the docker container docker exec -ti owncloud_server bash
2. Check current trusted_domains: occ config:system:get -- trusted_domains
3. Update the trusted domains: occ config:system:set trusted domains "1.1.1.1,2.2.2.2,localhost" System config value trusted_domains => 1.1.1.1,2.2.2.2,localhost set to empty string
4. Check updated value: occ config:system:get -- trusted_domains -- it doesn't change
5. Leave the docker container.
6. Check the config.php: sudo cat /path/to/owncloud/config/config.php -- array remains unchanged.

Expected behaviour

trusted_domains array should be updated with "1.1.1.1,2.2.2.2,localhost"

Actual behaviour

Previous value of trusted_domains is retained.

Server configuration

Operating system: Ubuntu 22.04

Web server: nginx? via Docker image

Database: mariadb via Docker image

PHP version: 7.4.3

ownCloud version: 10.13 (from docker-compose)

Updated from an older ownCloud or fresh install: fresh install

Where did you install ownCloud from: Docker image

Signing status (ownCloud 9.0 and above): not sure

Cannot sign in as all my domains are untrusted since I can't update the array reliably.

@mmattel something for the docs?

[iasdeoupxe]

Trusted domains are supposed to be set / configured only via OWNCLOUD_TRUSTED_DOMAINS according to:

https://doc.owncloud.com/server/10.13/admin_manual/installation/docker/

[icedwater]

Edit: Yes, but those didn't work for me at first, or I wouldn't have dug into the container. Let me add to the original question that the recommended docker .env approach failed when I followed the wrong instructions.

Thanks @iasdeoupxe for making me check again.

It would still be nice to furnish more examples for a provided command, though, especially since the default docker image doesn't have man pages.

Docker is always special and defies our normal documentation. The rule of thumb might be:

If you run into the situation "I did as documented, it does not change anything" then examine the config/overwrite.config.php file inside you running docker container. There you learn the details about the environment variable that needs to be used instead.

Example:

docker exec -ti my_little_owncloud grep -i trusted_domains config/overwrite.config.php
  if (getenv('OWNCLOUD_TRUSTED_DOMAINS') != '') {
    $domain = array_map('trim', explode(',', getenv('OWNCLOUD_TRUSTED_DOMAINS')));
    'trusted_domains' => $domain,
