docs: propose ADR 0044 reference deployment; fix manifest version
Add ADR 0044 (Status: Proposed), the single self-hosted reference deployment composed from pinned sources, and list it in the ADR index. Correct CLAUDE.md, which described manifest v6; the contracts accept only manifestVersion 7 (MODULE_MANIFEST_VERSION in packages/contracts/src/module-manifest.ts). No code changes.

|

|
||||
## Context
|
||||
|
||||
Phases 1–8 built and verified the platform contracts, but `README.md` and
|
||||
`docs/development/security.md` both record that Ekklesia is not deployed: there is no production
|
||||
instance, reverse proxy, public listener, Dashboard asset hosting, or deployment automation. The
|
||||
first real feature module, Signage, now exists in its own repository and needs a production host.
|
||||
|
||||
Several gaps only become concrete with a real deployment:
|
||||
|
||||
- Production requires certificate-verified PostgreSQL TLS (`verify-full` is the only production
|
||||
mode; ADR 0018), including for a database on the same host or Docker network.
|
||||
- Browsers require a secure context for the display service worker (ADR 0043), and production
|
||||
identity rejects `http` and loopback origins. A real, publicly trusted certificate is therefore
|
||||
required even on a private network.
|
||||
- Signage declares a storage bucket, so object storage is no longer optional for this deployment,
|
||||
and ADR 0004 left the production provider undecided.
|
||||
- A module repository is installed by cloning it into `modules/`. It depends on platform packages
|
||||
through `workspace:` ranges, so it can only be built inside an Ekklesia workspace, and the
|
||||
platform's committed `pnpm-lock.yaml` does not describe it.
|
||||
- There is no health endpoint, no backup procedure, and no upgrade procedure.
|
||||
|
||||
## Decision
|
||||
|
||||
Ekklesia provides **one reference self-hosted deployment**, kept in this repository under
|
||||
`deploy/`, that any organization can run on a single Linux host with Docker Compose. River of
|
||||
Glory Church is its first instance, but nothing church-specific enters this repository.
|
||||
|
||||
### Topology
|
||||
|
||||
One host, one Compose project, four long-running services on a private network:
|
||||
|
||||
| Service | Role |
|
||||
| --- | --- |
|
||||
| `proxy` | Caddy. Terminates TLS, serves the only published ports (443, 80 for redirect), routes `/api/*`, `/display/*`, `/assets/*` and the Dashboard to `api`, and a separate storage origin to `object-storage`. |
|
||||
| `api` | The `apps/api` image: Core, the enabled modules, and the built Dashboard and display host. Listens on the private network only. |
|
||||
| `postgres` | PostgreSQL 18 with TLS enabled, using a server certificate issued by an installation-private CA. |
|
||||
| `object-storage` | SeaweedFS, the same image family as development, reachable by browsers only through the proxy. |
|
||||
|
||||
Plus one operator-run, non-restarting service, `migrate`, described below.
|
||||
|
||||
### The API serves the Dashboard
|
||||
|
||||
The built Dashboard (`surfaces/shell`, `index.html` and its bundle) is served by `apps/api` from
|
||||
the same origin as `/api`, exactly as the display host already is. This keeps the identity
|
||||
system's default same-origin shape (`EKKLESIA_DASHBOARD_ORIGIN` unset) and avoids a second static
|
||||
server. The proxy never serves files from disk.
|
||||
|
||||
### TLS everywhere, without weakening ADR 0018
|
||||
|
||||
- **Browser-facing:** the proxy obtains publicly trusted certificates through ACME. The reference
|
||||
configuration uses the HTTP-01 challenge; the DNS-01 challenge is documented for installations
|
||||
that keep Ekklesia off the public Internet. A LAN-only installation can still hold a real
|
||||
certificate for an internal hostname this way.
|
||||
- **Tunnel ingress (optional):** an installation may publish the proxy through an outbound tunnel
|
||||
(the reference documents `cloudflared`) instead of opening inbound ports. The tunnel connector
|
||||
is a separate Compose service that connects to the proxy over HTTPS and verifies the proxy's
|
||||
certificate. The proxy accepts a tunnel-supplied client-address header **only** from the
|
||||
connector's network identity. It overwrites the single forwarding header it sends to `api`, and
|
||||
`api` trusts only the proxy. An installation that serves local displays should give the same
|
||||
hostname a LAN path to the proxy (split-horizon DNS), so displays do not depend on the
|
||||
Internet link.
|
||||
- **Database:** the deployment's setup script creates an installation-private CA once, issues a
|
||||
server certificate for the `postgres` service name, and gives the API only the CA certificate
|
||||
(`EKKLESIA_DATABASE_CA`). The API connects with `verify-full`. No plaintext or encryption-only
|
||||
exception is added to Core.
|
||||
|
||||
### Object storage
|
||||
|
||||
SeaweedFS is the reference provider for this deployment. Before the first production instance
|
||||
holds data, the existing storage integration suite (`core/tests/module-storage.integration.ts`,
|
||||
already run by `pnpm test:migrations:integration`) must pass against the exact SeaweedFS image the
|
||||
deployment pins. Browsers reach signed object URLs on a dedicated storage origin
|
||||
(`S3_DELIVERY_ENDPOINT`); the proxy forwards the original `Host` header unchanged so S3 signatures
|
||||
remain valid (ADR 0031). Any other S3-compatible provider remains a supported substitution.
|
||||
|
||||
### Composition from pinned sources
|
||||
|
||||
A running installation is defined by an **instance composition**: the platform version and the
|
||||
exact module sources it includes. The image build:
|
||||
|
||||
1. checks out the platform at a release tag;
|
||||
2. checks out each listed module at a pinned tag or commit SHA into `modules/<id>`;
|
||||
3. installs with `pnpm install --frozen-lockfile` against a lockfile **committed with the
|
||||
instance composition**, not the platform's own lockfile;
|
||||
4. runs `pnpm verify`-equivalent module and migration validation, then builds.
|
||||
|
||||
The instance composition (module list, pins, lockfile, non-secret configuration) lives in a
|
||||
separate repository owned by the installation. The reference deployment documents its shape and
|
||||
provides an empty example. Two builds from the same composition produce the same installed code.
|
||||
|
||||
This is a deployment mechanism, not a module distribution format. A packaged, installable module
|
||||
artifact (built outside an Ekklesia workspace, against published SDK versions) is a separate
|
||||
future decision.
|
||||
|
||||
### Migrations stay explicit
|
||||
|
||||
The `migrate` service runs `migrations:plan` then, only when an operator invokes it,
|
||||
`migrations:apply`, from the same image as `api`. The `api` service never applies migrations. The
|
||||
documented upgrade procedure is: build image → back up → run `migrate` → restart `api`.
|
||||
|
||||
### Health
|
||||
|
||||
`apps/api` gains two unauthenticated endpoints that reveal nothing about installed modules:
|
||||
|
||||
- `GET /api/v1/health/live` — the process is serving HTTP.
|
||||
- `GET /api/v1/health/ready` — the database is reachable and module startup completed.
|
||||
|
||||
Both return a fixed JSON body and `Cache-Control: no-store`. Compose health checks and external
|
||||
monitoring use them. `pnpm doctor` remains the detailed operator report.
|
||||
|
||||
### Backups
|
||||
|
||||
The reference deployment includes a scheduled backup job producing a `pg_dump` custom-format
|
||||
archive and a copy of every bucket under the installation's `S3_BUCKET_PREFIX`, written to a
|
||||
location outside the host. A restore procedure is documented and must be exercised once before
|
||||
an installation is treated as in production.
|
||||
|
||||
### Secrets
|
||||
|
||||
Secrets are supplied to Compose from a root-owned environment file on the host, never committed.
|
||||
This includes `EKKLESIA_IDENTITY_SECRET`, database and storage credentials, SMTP credentials, and
|
||||
`EKKLESIA_MODULE_SECRET__*` values. A secret manager is not required.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Ekklesia has a reproducible, documented way to run in production for the first time, and the
|
||||
ten-item launch checklist in `docs/development/security.md` becomes checkable against concrete
|
||||
configuration.
|
||||
- No Core guarantee is relaxed. The database TLS rule, explicit migrations, and the trusted-code
|
||||
module model are unchanged.
|
||||
- The platform and modules begin release tagging, because an instance composition can only pin
|
||||
what has a stable name.
|
||||
- An installation that wants Cloudflare Tunnel, a different proxy, or a managed database can
|
||||
substitute it, but the reference configuration is the one CI exercises.
|
||||
- Building modules inside a platform workspace remains a known limitation until a module
|
||||
packaging decision replaces the per-instance lockfile.
|
||||
|
||||
## Alternatives
|
||||
|
||||
- **Bare-metal systemd services.** Rejected as the reference: harder to reproduce and pin. Remains
|
||||
possible for installations that prefer it.
|
||||
- **Caddy-internal CA for browsers.** Rejected: every display device and admin browser would need
|
||||
the CA installed, which is unrealistic for volunteer-run screens.
|
||||
- **Relaxing database TLS inside a private Docker network.** Rejected: ADR 0018 deliberately has no
|
||||
such exception.
|
||||
- **Applying migrations automatically at API startup.** Rejected: contradicts the explicit-operator
|
||||
rule.
|
||||
- **Using `pnpm install` without a frozen lockfile when adding modules.** Rejected: the installed
|
||||
dependency graph would differ between builds.
|
||||
- **Kubernetes.** Rejected for the reference: disproportionate for a single church server.
|
||||
|
||||
## Deferred
|
||||
|
||||
- Module packaging and distribution (published SDK packages, signed module artifacts, an
|
||||
installer).
|
||||
- Multi-host, high availability, and managed-database guidance.
|
||||
- Container image publishing and automated deployment from CI.
|
||||
- Remote-access gates in front of the Dashboard (for example Cloudflare Access), documented as
|
||||
installation choices rather than platform requirements.
|
||||
- An authorized offline display descriptor or lease (tracked separately; required before relying
|
||||
on displays to cold-start without the server).
