# Private Matrix homeserver (matrix-tuwunel — the official conduwuit
|
|
# successor) for hyperhive agents, wrapped in a nixos-container so it
|
|
# doesn't fight any existing `services.matrix-*` the operator may
|
|
# already run on the host. Same shape as `nix/modules/hive-forge.nix`:
|
|
# shared host netns (`privateNetwork = false`) so agents reach it at
|
|
# `http://localhost:<httpPort>` (or via the configured server_name
|
|
# for federation), nixos-container only here for state + systemd-unit
|
|
# isolation.
|
|
#
|
|
# Container name `hive-matrix` (not `h-*`) so the lifecycle scanner
|
|
# ignores it; operator manages via the standard `nixos-container` CLI.
|
|
#
|
|
# Persistent state at `/var/lib/nixos-containers/hive-matrix/var/lib/
|
|
# matrix-tuwunel/` (survives container restart / host reboot). To
|
|
# wipe, destroy the container.
|
|
#
|
|
# Initial rollout (#548): federation enabled (needed for multi-hive
|
|
# swarms; trusted_servers starts empty so no actual federation traffic
|
|
# leaves until peers are explicitly listed), registration enabled via
|
|
# a `registration_token_file` known only to hive-c0re (so agents can't
|
|
# self-register without going through the coordinator), e2ee disabled
|
|
# per operator call (tracked for follow-up at #551).
|
|
#
|
|
# Provisioning model (matches `nix/modules/hive-forge.nix` shape):
|
|
# hive-c0re generates a 32-byte random `registration_token` on first
|
|
# boot, writes it to `/var/lib/hyperhive/matrix-register-token` (mode
|
|
# 0600, root-only), and bind-mounts that file read-only into the
|
|
# tuwunel container at the same path so tuwunel can read it via
|
|
# `registration_token_file`. hive-c0re then uses the token to register
|
|
# each agent account via the matrix-spec UIAA registration flow, and
|
|
# persists the returned `access_token` to `<agent-state>/matrix-token`
|
|
# so the agent's matrix MCP client can authenticate without ever
|
|
# seeing the shared registration token.
