Run OpenBSD on DigitalOcean for $4/month

To run OpenBSD on DigitalOcean for just $4 a month, start by installing the miniroot image from OpenBSD and verify its checksum. Sign up for DigitalOcean, navigate to Backups & Snapshots, upload the miniroot79.img file, and create a custom image named OpenBSD miniroot79. Create a droplet with 512MB memory, 1 vCPU, 500GB transfer, and 10GB disk space, using the custom image.

Add an SSH key for authentication and follow the prompts to complete the setup. Once the droplet is created, launch the web console and follow the on-screen instructions to install OpenBSD, remove unnecessary sets, and reboot the server. OpenBSD will be installed, and you can SSH into the server using the public IP address. For security, it's recommended to turn off password authentication and use a non-root user. Explore the OpenBSD Handbook and FAQ for further configuration and support.
