The reverse proxy is assumed to live outside this project (Caddy,
nginx, Traefik, whatever the operator already runs). The reference
compose stands up only the server: image-pinned via RM_VERSION,
named volume for operator state, localhost-bound so the proxy
reaches it on loopback.
docs/reverse-proxy.md covers what the proxy must forward — the
X-Forwarded-* headers, Host, and Connection: upgrade for the agent
WebSocket and live-log streams — plus the RM_TRUSTED_PROXY CIDR
rule that gates header trust. Worked examples for Caddy, nginx
(with the websocket upgrade map + 1h proxy_read_timeout for live
logs), and Traefik.
Self-hosted deployments already terminate TLS at Caddy/Traefik/nginx;
making the server do TLS too means double cert config, dual ACME
plumbing, and an untested code path. Drop RM_TLS_CERT/RM_TLS_KEY,
remove TLSEnabled() and the ListenAndServeTLS branch.
Replace the cookie's "Secure if TLS-in-process" check with a new
RM_COOKIE_SECURE flag (default true). Local HTTP-only testing sets
RM_COOKIE_SECURE=false; production is always behind a TLS proxy and
the cookie stays Secure.
Default port :8443 → :8080. docker-compose binds 127.0.0.1 only and
populates RM_TRUSTED_PROXY. spec.md §4.1/§10.1 rewritten with a
Caddyfile snippet and a hard "do not expose RM_LISTEN publicly"
warning. enrollResponse keeps cert_pin_sha256 in the shape but the
server can't introspect a cert it doesn't terminate — operator
pastes the proxy's hash into -cert-pin at install time.
