Requirements

	Minimum
Operating system	Linux, amd64 or arm64. Tested on Ubuntu 24.04; other systemd distributions that K3s supports should work.
CPU and memory	1 CPU, 2 GB of memory (2 CPUs and 4 GB recommended)
Disk	20 GB free recommended; more for databases and images
Network	A static public IPv4 address
Access	SSH as root, or as a user with passwordless sudo

The server should be dedicated to Zenavo. Setup installs K3s, which runs its own container runtime, Traefik for HTTP and ServiceLB for published ports; existing Docker containers or web servers on ports 80 and 443 will conflict.

Ports

Open these in your cloud provider's firewall or security group. See Firewall & Security for how to restrict them.
