Configure Zitadel with Traefik

With these examples, you create and run a minimal Traefik configuration for Zitadel with Docker Compose. Whereas the guide focuses on the configuration for Traefik, you can inspect the settings for the Zitadel API, the Zitadel login and the database in the base Docker Compose file.

For running Traefik, you will extend the base Docker Compose file with the Traefik specific Docker Compose file.

specific docker-compose.yaml

services:  proxy-disabled-tls:    image: "traefik:latest"    volumes:      - "./traefik-disabled-tls.yaml:/etc/traefik/traefik.yaml:ro"    ports:      - "80:80"    networks:      - app    depends_on:      zitadel-disabled-tls:        condition: 'service_healthy'  proxy-external-tls:    image: "traefik:latest"    volumes:      - "./traefik-external-tls.yaml:/etc/traefik/traefik.yaml:ro"      - "./selfsigned.crt:/etc/certs/selfsigned.crt:ro"      - "./selfsigned.key:/etc/certs/selfsigned.key:ro"    ports:      - "443:443"    networks:      - app    depends_on:      zitadel-external-tls:        condition: 'service_healthy'  proxy-enabled-tls:    image: "traefik:latest"    volumes:      - "./traefik-enabled-tls.yaml:/etc/traefik/traefik.yaml:ro"      - "./selfsigned.crt:/etc/certs/selfsigned.crt:ro"      - "./selfsigned.key:/etc/certs/selfsigned.key:ro"    ports:      - "443:443"    networks:      - app    depends_on:      zitadel-enabled-tls:        condition: 'service_healthy'

You can either setup your environment for TLS mode disabled, TLS mode external or TLS mode enabled.

TLS mode external

Traefik terminates TLS and forwards the requests to Zitadel via unencrypted h2c. This example uses an unsafe self-signed certificate for Traefik. By executing the commands below, you will download the files necessary to run Zitadel behind Traefik with the following config:

traefik-external-tls.yaml

log:  level: "DEBUG"providers:  file:    filename: "/etc/traefik/traefik.yaml"entrypoints:  web:    address: ":443"http:  routers:    zitadel:      entryPoints:        - "web"      service: "zitadel"      rule: '!PathPrefix(`/ui/v2/login`)'      tls: {}    login:      entryPoints:        - "web"      service: "login"      rule: 'PathPrefix(`/ui/v2/login`)'      tls: {}  services:    zitadel:      loadBalancer:        passHostHeader: true        servers:          - url: "h2c://zitadel-external-tls:8080"    login:      loadBalancer:        passHostHeader: true        servers:          - url: "http://login-external-tls:3000"tls:  stores:    default:      defaultCertificate:        certFile: /etc/certs/selfsigned.crt        keyFile: /etc/certs/selfsigned.key

username: zitadel-admin@zitadel.127.0.0.1.sslip.io

If the management console loads normally, you know that the HTTP and gRPC-Web and gRPC APIs are working correctly.

TLS mode enabled

Traefik terminates TLS and forwards the requests to Zitadel via encrypted HTTP/2. This example uses an unsafe self-signed certificate for Traefik and the same for Zitadel. By executing the commands below, you will download the files necessary to run Zitadel behind Traefik with the following config:
