--- title: Set up ZITADEL with Docker Compose sidebar_label: Docker Compose description: Deploy ZITADEL with Docker Compose — from a 2-minute localhost quickstart to a hardened homelab setup with TLS, caching, and observability. --- import NoteInstanceNotFound from './troubleshooting/_note_instance_not_found.mdx'; import DefaultUser from './_defaultuser.mdx' import Next from './_next.mdx' This guide takes you from zero to a running ZITADEL instance in minutes and then shows you how to harden it for a homelab or semi-production deployment. ## Prerequisites - Docker Engine 24+ with the Compose plugin (`docker compose`) - A machine with at least 2 GB RAM See [Requirements](/self-hosting/manage/requirements) for supported database, cache, and proxy versions. ## Stage 1 — Quickstart (2 minutes) Download the two required files, copy the example config, and start: ```shell mkdir zitadel-compose && cd zitadel-compose # Download the compose file and example environment curl -fsSLO https://raw.githubusercontent.com/zitadel/zitadel/main/deploy/compose/docker-compose.yml && curl -fsSLO https://raw.githubusercontent.com/zitadel/zitadel/main/deploy/compose/.env.example # Create your environment file and start cp .env.example .env docker compose up -d --wait ``` That's it. Visit [http://localhost:8080](http://localhost:8080) to open the login screen. The base stack runs: **Traefik** ([reverse proxy](/self-hosting/manage/reverseproxy/reverse_proxy)) → **ZITADEL API** (Go) + **ZITADEL Login** (Next.js) → **PostgreSQL**. All routing, including [gRPC over HTTP/2](/self-hosting/manage/http2), is handled automatically by Traefik — no extra configuration needed. ## Stage 2 — Homelab / Semi-Production ### Use your own domain Edit `.env` and set your real domain (see [Custom Domains](/self-hosting/manage/custom-domain) for details): ```dotenv ZITADEL_DOMAIN=auth.example.com ``` ### Enable TLS Pick a TLS mode and download the matching overlay file: | Mode | Overlay file | When to use | |------|-------------|-------------| | Let's Encrypt | `docker-compose.mode-letsencrypt.yml` | Public domain, automatic certs | | External TLS | `docker-compose.mode-external-tls.yml` | Behind a load balancer, CDN, or WAF that terminates TLS | | Local TLS | `docker-compose.mode-local-tls.yml` | Self-signed certs for LAN-only access | Download the overlay you need, then start with both files: ```shell # Download the overlay (replace with your chosen mode) curl -fsSLO https://raw.githubusercontent.com/zitadel/zitadel/main/deploy/compose/docker-compose.mode-letsencrypt.yml # Start with the overlay docker compose --env-file .env \ -f docker-compose.yml \ -f docker-compose.mode-letsencrypt.yml \ up -d --wait ``` Set `LETSENCRYPT_EMAIL` in `.env` to receive certificate expiry notifications. ### Harden secrets The masterkey [encrypts sensitive data at rest](/concepts/architecture/secrets). Once ZITADEL has been initialized with a masterkey, it **cannot be changed** without losing access to encrypted data. Generate it **before first start** and store it safely. ```shell # Generate a secure masterkey (must be exactly 32 characters) ZITADEL_MASTERKEY=$(tr -dc A-Za-z0-9 > .env # Set strong database passwords echo "POSTGRES_ADMIN_PASSWORD=$(tr -dc A-Za-z0-9 > .env echo "POSTGRES_ZITADEL_PASSWORD=$(tr -dc A-Za-z0-9 > .env ``` The commands above cover the masterkey and the database passwords. The **initial admin user** (`zitadel-admin`) has a password too, defaulting to `Password1!`. To set your own before the first start, add it to `.env`: ```dotenv ZITADEL_FIRSTINSTANCE_ORG_HUMAN_PASSWORD=MyInitialPassw0rd! ``` The initial admin password must satisfy the default [password complexity policy](/guides/manage/console/default-settings#password-complexity): at least 8 characters, including an uppercase letter, a lowercase letter, a number, and a symbol. A password that doesn't meet these requirements causes the initial setup to fail with a password complexity error. Like all `ZITADEL_FIRSTINSTANCE_*` variables, it is only applied during the first start; change it later from the Console. ### External URL settings These three settings **must match your public endpoint exactly**: | Setting | Meaning | Example | |---------|---------|---------| | `ZITADEL_DOMAIN` | The public domain users type in | `auth.example.com` | | `ZITADEL_EXTERNALPORT` | The port visible to users | `443` for HTTPS | | `ZITADEL_EXTERNALSECURE` | Whether the public URL uses HTTPS | `true` for any TLS mode | If these don't match reality, ZITADEL returns **"Instance not found"** errors. This is the most common deployment issue — see [TLS Modes](/self-hosting/manage/tls_modes) for details. ### Enable caching with Redis See [Cache Configuration](/self-hosting/manage/cache) for all available options. Add these to `.env`: ```dotenv ZITADEL_CACHES_CONNECTORS_REDIS_ENABLED=true ZITADEL_CACHES_INSTANCE_CONNECTOR=redis ZITADEL_CACHES_MILESTONES_CONNECTOR=redis ZITADEL_CACHES_ORGANIZATION_CONNECTOR=redis ``` Then start with the `cache` profile: ```shell docker compose --env-file .env -f docker-compose.yml --profile cache up -d --wait ``` ## Stage 3 — Beyond Compose ### Production-like init/setup/start split For controlled upgrades, separate [database initialization from the running API](/self-hosting/manage/updating_scaling): ```shell curl -fsSLO https://raw.githubusercontent.com/zitadel/zitadel/main/deploy/compose/docker-compose.prodlike.yml && docker compose --env-file .env \ -f docker-compose.yml \ -f docker-compose.prodlike.yml \ up -d --wait ``` This creates three ZITADEL containers: 1. `zitadel-init` — runs database migrations (one-shot) 2. `zitadel-setup` — configures the instance (one-shot) 3. `zitadel-api` — starts the API server (long-running) ### Enable observability Set in `.env`: ```dotenv ZITADEL_INSTRUMENTATION_TRACE_EXPORTER_TYPE=grpc ``` Download the collector configuration and start with the `observability` profile: ```shell curl -fsSLO https://raw.githubusercontent.com/zitadel/zitadel/main/deploy/compose/otel-collector-config.yaml && docker compose --env-file .env -f docker-compose.yml --profile observability up -d --wait ``` Traces are logged to the collector's stdout by default (`docker compose logs otel-collector`). To forward traces to your own backend (Grafana Tempo, Jaeger, OpenObserve, etc.), set `OTEL_BACKEND_ENDPOINT` in `.env` and uncomment the `otlp` exporter in `otel-collector-config.yaml`. See [Metrics](/self-hosting/manage/metrics/overview) for Prometheus scraping and available metric types. ### Scale API replicas Scaling requires the **prodlike overlay** so that migrations run once in `zitadel-init` instead of on every replica. ```shell docker compose --env-file .env \ -f docker-compose.yml \ -f docker-compose.prodlike.yml \ up -d --scale zitadel-api=3 ``` ### Updating ZITADEL Edit `ZITADEL_VERSION` in `.env`, then: ```shell docker compose --env-file .env -f docker-compose.yml pull docker compose --env-file .env -f docker-compose.yml up -d --wait ``` `ZITADEL_FIRSTINSTANCE_*` and `ZITADEL_DEFAULTINSTANCE_*` environment variables are only applied during the **initial setup**. To change settings on an existing installation, use the Admin Console or Admin API. ### Moving to Kubernetes Docker Compose is ideal for getting started and homelab deployments. For production workloads, review the [Production Checklist](/self-hosting/manage/productionchecklist) and deploy with the official [Helm chart for Kubernetes](/self-hosting/deploy/kubernetes). The compose pack and the Helm chart share the same application configuration model (`ZITADEL_*` environment variables), so migration is straightforward.
