Quickstart Guide

Prerequisites

• A Linux host with Docker + Docker Compose (the v2 plugin docker compose or the v1 standalone docker-compose both work).
• Two hostnames that resolve to the host: one for the SSO UI (your stack.ssoHost), one for the proxy mgmt UI (your stack.proxyHost). On a real network add DNS records; for a local try, add them to /etc/hosts.
• Port 80 + 443 reachable from the internet if you want Let's Encrypt certs; otherwise the proxy serves a self-signed fallback (browsers warn — expected for LAN use).

---

1. Clone

git clone --recursive https://github.com/theta42/theta-env.git
cd theta-env

--recursive fetches the two submodules (sso-manager-node, proxy) in one step. If you forgot it:

git submodule update --init --recursive

---

2. Configure setup.env (enter your domain once)

cp setup.env.example setup.env
$EDITOR setup.env      # set CFG_BASE_DN to your domain, as a base DN

Your domain is entered once, as the LDAP base DN. The SSO/proxy hostnames default to sso.<domain> / proxy.<domain>, derived from it, so for most setups CFG_BASE_DN is the only value you set:

setup.env key	Example	Notes
CFG_BASE_DN	dc=lab,dc=local	your directory base — required
CFG_SSO_HOST	sso.lab.local	optional, defaults to sso.<domain>
CFG_PROXY_HOST	proxy.lab.local	optional, defaults to proxy.<domain>
CFG_ADMIN_UID	admin	optional, defaults to admin
CFG_ADMIN_EMAIL	admin@<proxyHost>	optional

setup.env is used only on the first run to generate ./config/; after that ./config/*.js are operator-owned and setup.env is ignored. Secrets (LDAP admin password, JWT, admin password, service-account password) are generated into ./config/*.js on first run — do not put them in setup.env. See setup.env.example for the full annotated shape, and config.example/ + each submodule's secrets.js.example for the generated file shape.

Migrating from an older .env-based deployment? If .env/proxy.env exist, ./setup.sh migrates them into ./config/ preserving your existing secrets — no need to write a setup.env.

---

3. Run

./setup.sh

The first run reads setup.env, generates ./config/sso-secrets.js + ./config/proxy-secrets.js with your domain filled in everywhere plus random secrets, then builds and starts the stack in the same run (no edit-and-re-run). What happens:

1. Snapshots state to ./backups/<timestamp>/ before rebuilding (a no-op on the very first run).
2. Builds + starts sso-manager, waits for /health.
3. Runs the bootstrap inside the sso-manager container — creates the LDAP service account, your first admin, and the proxy's OAuth client, and writes the generated client id + secret into ./config/proxy-secrets.js.
4. Builds + starts proxy, waits for /health.
5. Prints your first-admin login + the public URLs.

The first run builds two Docker images (a few minutes). Subsequent runs are fast.

---

4. Point DNS at the host

stack.ssoHost and stack.proxyHost (from ./config/sso-secrets.js) must resolve to the host running the stack. Add DNS records, or for a local try:

echo "127.0.0.1 sso.lab.local proxy.lab.local" | sudo tee -a /etc/hosts

(The proxy needs port 80 reachable for Let's Encrypt; on a LAN without that it serves a self-signed cert — browsers will warn, which is fine for home-lab use.)

---

5. Log in

Open https://<SSO_HOST> and log in as your bootstrap admin (bootstrap.adminUid / bootstrap.adminPass). From there you can add users, groups, and OAuth clients.

The proxy mgmt UI is at https://<PROXY_HOST> (same admin SSO login protects it). Add the Host records you want to protect with OIDC.

First-run fallbacks (if DNS/TLS isn't ready yet): SSO UI at http://127.0.0.1:3001, proxy UI at http://127.0.0.1:3000.

---

Re-running

./setup.sh is idempotent — safe to re-run after editing ./config/, after a docker compose down, or after restoring from backup. It snapshots state, then converges the stack to your ./config/ values (LDAP service account + admin passwords are reset to the config; the OAuth client is kept if proxy-secrets.js already holds its creds).

---

Direct LDAP for legacy apps

Legacy apps bind LDAP directly over LDAPS:

ldapsearch -x -H ldaps://<host>:636 \
  -D "cn=ldapclient,ou=people,dc=lab,dc=local" -W \
  -b "ou=people,dc=lab,dc=local" '(objectClass=posixAccount)' cn mail

Use the cn=ldapclient service account (read-only, the bootstrap created it) or the admin DN. Use LDAPS (636), not plain LDAP.

---

Backups and restore

./setup.sh auto-snapshots ./config/ + LDAP + both Redis to ./backups/<ts>/ before each rebuild (keeps the last BACKUP_KEEP, default 5). For manual backups and the full restore runbook (full / Redis-only / LDAP-only, with the AOF-vs-RDB note), see the Backups and restore section of the README. Quick LDAP backup:

docker compose exec sso-manager slapcat -f /etc/openldap/slapd.conf \
  -b "<base>" > backup-$(date +%F).ldif

---

Next steps

• Add users / groups in the SSO UI.
• Add Host records in the proxy UI to protect your apps with OIDC.
• Mint API tokens to drive either app's management API from scripts/CI: under API Tokens in each UI, mint a personal access token and use it as Authorization: Bearer sso_… (SSO) or prx_… (proxy). A token authenticates as its creator with their permissions. See each submodule's DEPLOYMENT.
• See Architecture for how it all fits together, and Standalone to run either project on its own.
