Collapse the two proxy shapes (path_prefix + host) to a single checkbox: a
service is either port-only, or exposed at <service-name>.<gateway.domain>. Path
routes and their prefix-stripping foot-guns are gone; the subdomain is always the
service name (rename the service to change it).
- Schema: CaddySpec is just `enable` (presence = expose). service_proxy_targets
returns (expose, port, base_url); Deployment carries `subdomain` (was
proxy_path/proxy_host). Registry/deploy/mesh/CLI updated in lockstep.
- Generator: compute_routes emits one host route per exposed service/frontend
(address = name). acme mode = one *.<domain> site with a reverse_proxy matcher
per service + a file_server matcher per frontend; the :<port> site redirects to
the dashboard. off mode = a HTTP control plane on :<port> (dashboard at / +
/api → castle-api); other services are port-only.
- Dashboard/API: castle-app and castle-api are ordinary subdomains. The dashboard
derives the API base at runtime (castle-api.<domain> on a subdomain, else /api)
and calls it cross-origin — castle-api already allows CORS *. Frontends build
with VITE_BASE=/ (served at their subdomain root).
- CLI: `service create` drops --path/--host; --no-proxy makes it port-only.
- Docs/tests reworked for the model; docs use generic placeholders only (no
personal host/domain/IP details).
acme mode fully replaced the internal-CA path (which required installing a private
CA on every device — the exact pain, esp. on Android, that acme avoids). Remove
`internal` entirely and simplify how services declare host routes.
- Generator (caddyfile.py): drop the `tls internal` branch — modes are now
`off` | `acme`. In acme mode the published subdomain is the **first DNS label**
of `proxy.caddy.host` (a bare `claw`, or a legacy `claw.civil.lan`, both →
`claw.<domain>`), so services stay domain-agnostic and the declared value is
authoritative again (no more silent service-name override). Shared
`_host_matcher_block` reused by off-mode and the acme wildcard site.
- castle-api: delete `GET /gateway/ca.crt`, `_gateway_ca_pem`, `_ca_fingerprint`
and the now-unused imports; drop `ca_fingerprint` from `GatewayInfo` (keep
`tls`).
- Dashboard: remove the CA-cert download button + unused imports; drop
`ca_fingerprint` from the `GatewayInfo` type.
- Tests: replace TestCaddyfileTlsInternal with an off-mode class (keeps the
runner-agnostic host-route coverage); acme tests assert first-label derivation
incl. label-wins-over-service-name; drop the castle-api CA-endpoint test.
- Docs: registry.md + dns-and-tls.md — two-mode tables (off|acme), remove the
internal sections/CA-download, document the bare-label host convention; note a
domain-less node stays on `off`.
A conceptual companion to registry.md's field-level gateway reference. Covers the
two questions (resolve / trust) an internal-only LAN service must answer:
- DNS: gateway-as-ingress, path-prefix vs host routes, LAN name resolution,
wildcard records, split-horizon (internal names, no public A records), and the
private-TLD vs public-subdomain zone styles with the worked router/wild-central
topology.
- TLS: the three gateway.tls modes (off / internal / acme) with when-to-use, the
internal-CA distribution pain vs the acme DNS-01 "no client setup" win, the
secure-context (WebCrypto) rationale, the put-a-service-on-HTTPS recipe,
operational prerequisites (443/80 bind, plugin caddy, DNS token, staging), and a
decision table.
