Docker Deployment

← Back to Home

The proxy ships as a single all-in-one Docker image bundling OpenResty + the Node management app + Redis in one container, mirroring the bare-metal ops/install.sh layout. This is the easiest way to run the proxy standalone, or as part of the unified theta-env stack.

Quick start (standalone)

git clone https://github.com/theta42/proxy.git
cd proxy
mkdir -p config && chmod 700 config
cp secrets.js.example config/proxy-secrets.js   # set OIDC/LDAP wiring
$EDITOR config/proxy-secrets.js
docker compose up -d --build

• Proxy (public, auto-SSL): https://<host>/
• Management UI / API: http://127.0.0.1:3000/ (bound to localhost)
• Health: http://127.0.0.1:3000/health → {"status":"ok"}

How configuration works

The app loads config via @simpleworkjs/conf, which deep-merges, in order:

1. conf/base.js (committed defaults)
2. conf/<NODE_ENV>.js (optional)
3. conf/secrets.js (gitignored)
4. app_* environment variables — the highest-precedence layer

The bundled docker-compose.yml mount ./config/proxy-secrets.js at /config, and docker-entrypoint.sh symlinks it into /app/conf/secrets.js so the app reads the OIDC + LDAP + auth wiring from the file. No app_* env is passed — app_* env beats secrets.js, so the file is authoritative only if the matching app_* env is absent. See secrets.js.example for the shape.

Any env var starting with app_ overrides the merged config; the rest of the name splits on double-underscore (__) into a nested path. Values are JSON.parse-coerced when possible, kept as strings otherwise. app_* env is still supported for advanced/standalone use — add the vars to the compose environment: block yourself (the bundled compose no longer sets them).

Requires @simpleworkjs/conf >= 1.1.0. The app_* env layer is not honored on 1.0.0. The lock is already on ^1.1.0.

Key app_* variables

Env var	Sets
app_oidc__issuer	conf.oidc.issuer (browser-facing SSO URL)
app_oidc__authorizationEndpoint	conf.oidc.authorizationEndpoint
app_oidc__tokenEndpoint	conf.oidc.tokenEndpoint (server-to-server; can be internal)
app_oidc__userinfoEndpoint	conf.oidc.userinfoEndpoint (server-to-server)
app_oidc__endSessionEndpoint	conf.oidc.endSessionEndpoint
app_oidc__clientId / app_oidc__clientSecret	OIDC client creds
app_oidc__redirectUri	conf.oidc.redirectUri (must match the SSO client)
app_oidc__enabled	conf.oidc.enabled (boolean)
app_ldap__url	conf.ldap.url (ldaps://…:636 or ldap://…:389)
app_ldap__bindDN / app_ldap__bindPassword	LDAP service account
app_ldap__searchBase / app_ldap__userFilter	user search
app_ldap__tlsOptions__rejectUnauthorized	false for self-signed LDAPS
app_ldap__tlsOptions__ca	path to a CA cert for strict trust
app_auth__adminUsers	local anti-lockout admin (uid)
app_auth__adminGroups	SSO/LDAP groups that are global admin (JSON array)
app_redis__prefix	conf.redis.prefix (default proxy_)

See DEPLOYMENT.md for the complete reference.

OpenResty runtime env

Variable	Default	Description
RESOLVER	127.0.0.11	DNS for upstream names in Host records (Docker's embedded DNS)
REAL_IP_FROM	empty	Trusted CIDR for X-Real-IP. Empty = the proxy is the front (removes the real_ip block). Set to an upstream proxy's CIDR if one sits in front.

Auto-SSL / Let's Encrypt

lua-resty-auto-ssl stores certs in the bundled Redis. Redis is now AOF+RDB persisted to the proxy-data volume (not in-memory), so Let's Encrypt certs survive container recreation — no re-issue / rate-limit on rebuild. Port 80 is required for HTTP-01 challenges (mapped in the compose). Back up + restore Redis to back up + restore cert state (see Backups and restore in DEPLOYMENT.md).

Fronting an SSO Manager

The proxy is a natural front for theta42/sso-manager-node: it terminates TLS for the SSO's UI and protects it with OIDC login, while also binding to the SSO's LDAP directly for user lookups. To run both together:

1. One Docker network so the proxy reaches the SSO internally at http://sso-manager:3001 (token/userinfo) and ldaps://sso-manager:636.
2. Set the SSO's app_oauth__issuer to the browser-facing HTTPS URL the proxy serves the SSO at (e.g. https://sso.example.com).
3. Register the proxy as an OIDC client in the SSO, with redirectUri matching https://proxy.example.com/api/auth/oidc/callback.
4. LDAP: point app_ldap__url at ldaps://sso-manager:636, create a dedicated service account (cn=ldapclient,ou=people,…), and for the SSO's self-signed LDAPS cert set app_ldap__tlsOptions__rejectUnauthorized=false (or mount the cert and use app_ldap__tlsOptions__ca=<path>).

The theta42/theta-env unified repo automates all four steps with ./setup.sh — see theta-env docs.

Bare metal

Prefer a systemd install? See the Installation Guide for the ops/install.sh automated installer on Debian/Ubuntu.
