# Requirements

> Supported host contract and prerequisites for the current self-hosted production target.

The Phase 1 self-hosted production contract targets native `linux/amd64` hosts using `systemd`.

| Distribution      | Minimum release | Minimum kernel |
| ----------------- | --------------: | -------------: |
| Ubuntu Server LTS |           24.04 |            6.8 |
| Debian            |              13 |           6.12 |

Additional production-contract requirements include Docker Engine 27 or newer, Docker Compose plugin 2.30 or newer, persistent local storage, routable signaling/media addresses or explicit NAT configuration, and the DNS/TLS prerequisites required by your SIP, WSS, TURN, and API endpoints.

The current CLI enforces `linux/amd64` and checks that Docker is available. Not every supported-host-contract item is automatically validated by `leamout doctor` yet.

Docker Desktop, WSL, NAS operating systems, nested/containerized Leamout hosts, unsupported distributions, and `arm64` are outside the Phase 1 production support contract.
