NextCloud Docker Setup

I found NextCloud to be very powerful, flexible and expandable. Specifically, I setup NextCloud on my synology NAS via docker, manually upload my file (while will be essentially faster) for the initial sync, then use NextCloud as a combination of Dropbox and Google Drive.

Setup

1. Setup a new network for the docker;
2. Setup path as a folder to store data;
3. Using the following docker compose file to build docker images (sensitive information is masked in < and >). The command for set up is docker-compose up -d, and the command for update is sudo docker-compose pull && sudo docker-compose up -d;
4. Login with setting database to mariadb;
5. After manually uploading files to the destination, you can add files to nextcloud by sudo -u www-data php occ files:scan --path "<username>/files/<path_under_files>;
6. To recursively delete, use find . -type d -name '@eaDir' -exec rm -r {} +;
7. Remember to add trusted domains.
