ownCloud is an open-source file hosting and synchronization platform that enables secure storage, sharing, and collaboration on files across devices. It provides features like file versioning, calendar and contacts integration, and extensibility through apps, while giving you complete control over your data. The Vultr Marketplace provides a pre-configured ownCloud instance on Ubuntu with Nginx, PHP, and MySQL, enabling quick deployment and setup on a Vultr server.

This guide explains deploying and using Vultr's ownCloud Marketplace Application. You will deploy an instance, configure DNS and SSL, access the web interface, manage files and users, and implement best practices for production deployments.

Deploy Vultr's ownCloud Marketplace Application

1. Log in to your Vultr Customer Portal and click the Deploy Server button.

2. Select your preferred server type.

3. Choose a server location.

4. Select a server plan with at least 1GB RAM and 1 CPU core for personal use, or 2GB RAM and 2 CPU cores for team deployments.

5. Click the Configure button to proceed.

6. Under Marketplace Apps, search for ownCloud and select it as the Marketplace Application.

7. Select the Limited Login option from the Additional Features section to create a limited user with sudo access.

8. Review your configurations and click the Deploy Now button to start deployment.

   Note

   It may take up to 10 minutes for your server to finish installing ownCloud.
