Deploy Nextcloud, ownCloud, and Seafile with Docker Compose. Production-ready configs with .env templates and one-command deployment.
Seafile is the simplest with a single container. Nextcloud is the most feature-rich but needs more resources. ownCloud is enterprise-focused.
The software itself needs minimal space. Your data drives storage needs. Nextcloud and ownCloud work well with external storage mounts (S3, NFS).
