To run Traefik with Docker Compose, you need a docker-compose.yml file that defines Traefik as a service. Here’s a basic example to get you started:

version: '3'

services:
  traefik:
    image: traefik:v2.10
    command:
      - "--log.level=DEBUG"
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--entryPoints.web.address=:80"
    ports:
      - "80:80"
      - "8080:8080"

Here’s a basic outline of how to deploy Supabase locally:

1. Clone the Supabase Repository

First, clone the official Supabase repository from GitHub.

git clone https://github.com/supabase/supabase

2. Navigate to the Project

Change your directory to the newly cloned repository.

cd supabase/docker

3. Start Supabase using Docker Compose

docker compose up

This command starts all the necessary services for a complete Supabase environment, including the Postgres database, Auth services, and Realtime server.

Integrating Supabase with Traefik

Integrating Supabase with Traefik involves configuring Traefik to handle the routing and load balancing for Supabase services. This integration not only brings the robust features of Traefik into play but also optimizes the performance and security of your Supabase deployment.

Steps to Integrate Supabase with Traefik

1. Understanding the Default Supabase Setup:

• Initially, Supabase uses Kong as its API gateway.
• Your current setup might have several services like PostgREST, Realtime, and GoTrue (for authentication), all routed through Kong.

2. Setting Up Traefik:

• First, you need to remove or disable Kong in your Docker Compose setup.
• Introduce Traefik as the primary reverse proxy. This involves adding a Traefik service in your docker-compose.yml file, as outlined in the previous section.

3. Configuring Traefik to Work with Supabase Services:

• Each Supabase service (PostgREST, Realtime, GoTrue) needs to be configured to work with Traefik. This typically involves setting labels in the Docker Compose file to define routing rules.

• For instance, you might add labels to the storage service to define how Traefik should route requests to it:

labels:
  - "traefik.http.routers.storage.rule=Host(`${SUPABASE_HOST}`) && PathPrefix(`/storage/v1`)"
  - "traefik.http.middlewares.storage-rx.replacepathregex.regex=^/storage/v1(.*)"
  - "traefik.http.middlewares.storage-rx.replacepathregex.replacement=$$1"
  - "traefik.http.services.storage.loadbalancer.server.port=5000"

• Repeat similar configurations for other services like Realtime and GoTrue, ensuring that the domain names and ports match your setup.

3.1 Authentication

Supabase Studio doesn’t use any credentials for access, which is why you need to use your own authentication middleware with Traefik:

labels:
  - "traefik.http.routers.supabase.middlewares=auth-studio"
  - "traefik.http.middlewares.auth-studio.basicauth.users=${SUPABASE_BASIC_AUTH_CREDS}"
  - "traefik.http.middlewares.auth-studio.basicauth.removeheader=true"

You can use any way of authentication you want, the most popular are basic auth or an SSO service like Authelia.
