Installation Options

For a standard Ubuntu server, use the automated installer. For step-by-step Docker and CapRover commands, see Manual Setup.

Standard VPS

• Ubuntu 24.04, AMD64/ARM64, public IPv4, root access, at least 1 GB RAM.
• Allow SSH, 80/tcp, 443/tcp, and 3000/tcp in provider firewalls.
• Set a wildcard A record (for example, *.apps.example.com) to the server's public IP.
• Avoid Docker installed via snap. For an existing Docker Engine, verify sudo docker version and sudo docker run --rm hello-world.

DigitalOcean

• Fresh Ubuntu Droplet: Follow Getting Started.
• CapRover Marketplace image: Docker and CapRover are preinstalled. Continue with DNS and dashboard setup.
• New DigitalOcean customers: Referral signup for any currently available promotional credit. Offers vary.

The same firewall, RAM and wildcard DNS requirements apply to both options.

OpenStack

• Create an Ubuntu 24.04 instance with public/floating IPv4, SSH key, outbound connectivity and at least 1 GB RAM.
• Allow SSH, 80/tcp, 443/tcp, and 3000/tcp in security groups and the guest firewall.
• Point wildcard DNS to the public IP. Continue with Getting Started.

Older Heat template: The existing template contains hard-coded values and problematic network/security defaults. Review and correct it before using it.
