Changing the domain of your dockerized Nextcloud instance.

I recently purchased a new domain and wanted to move my dockerized nextcloud installation.

At the time of writing this post, this feature was not available as stated in the documentation.

The following way workaround made it possible for me, although i solely use nextcloud for file syncing. This may or may not create issues for other purposes like calender or contact syncing.

How to do it: #

First, update the domain you set in the .env file in your nextcloud directory.

Make sure that your container is running since we will need to make some config changes from the inside.

Have a look at the html/config/config.php file. You may find some key-value pairs containing you old domain.

For me, this includes:

• trusted_domains
• overwritehost
• overwrite.cli.url

Instead of changing them directly, run the following command for each of them:

docker exec -it -u www-data nextcloud php occ config:system:set $KEY --value=example.com

Restart your container and you should be good to go - That’s it!
