Manage & Monitor Self-hosted Supabase

This flow shows the main steps to set up Supabase on your own server using Docker, from preparing the environment to running and accessing the services.

Execution Sample

Supabase

docker-compose up -d
# Starts Supabase services in background

# Access dashboard at http://localhost:54323

# Use Supabase APIs as usual

This code runs the Supabase services using Docker Compose and makes them available locally.

Process Table

Step	Action	Command/Detail	Result/State
1	Prepare server	Ensure Linux server with Docker installed	Server ready for Docker
2	Install Docker Compose	Install docker-compose tool	Docker Compose ready
3	Download Supabase files	git clone --depth 1 https://github.com/supabase/self-hosting && cd self-hosting/docker	Supabase config files available
4	Configure env vars	Edit .env file with DB passwords, ports	Environment configured
5	Start services	docker-compose up -d	Supabase containers running
6	Check status	docker ps	All Supabase containers healthy
7	Access dashboard	Open http://localhost:54323	Supabase dashboard loads
8	Use APIs	Call Supabase REST or GraphQL endpoints	APIs respond correctly

Key Moments - 3 Insights

Why do we need to configure environment variables before starting services?

Because environment variables set important settings like database passwords and ports. Without them, services may fail to start or be insecure. See execution_table step 4.

What does 'docker-compose up -d' do exactly?

It starts all Supabase services in the background as containers, making them ready to use. This is shown in execution_table step 5.

How can I check if all Supabase services are running correctly?

By running 'docker ps' to see running containers and 'docker-compose logs -f' to view live logs, as shown in steps 6 and 9.

Concept Snapshot

Self-hosting Supabase:
- Prepare server with Docker & Docker Compose
- Download Supabase config files
- Set environment variables (DB passwords, ports)
- Run 'docker-compose up -d' to start services
- Access dashboard and APIs locally
- Use 'docker-compose down' to stop services

Full Transcript

Self-hosting Supabase means running Supabase services on your own server instead of using the cloud. First, prepare a Linux server and install Docker and Docker Compose. Then download the Supabase configuration files from their repository. Next, configure environment variables like database passwords and ports in the .env file. After that, run 'docker-compose up -d' to start all Supabase services as Docker containers. You can check the status with 'docker ps' and view logs with 'docker-compose logs -f'. Access the Supabase dashboard via the local URL and use the APIs as usual. When done, stop the services with 'docker-compose down'. This setup gives you full control over your Supabase instance.

Practice

1. What is the main benefit of self-hosting Supabase compared to using the hosted service?

easy

A. It provides free hosting without limits.

B. It automatically scales without any setup.

C. You don't need to manage any servers or updates.

D. You get full control over your backend and data.

Solution

1. Step 1: Understand self-hosting meaning

   Self-hosting means you run the service on your own machine or server, giving you control.

2. Step 2: Compare benefits

   Unlike hosted services, self-hosting lets you manage data and backend fully, but requires maintenance.

3. Final Answer:

   You get full control over your backend and data. -> Option D

4. Quick Check:

   Self-hosting = full control [OK]

Hint: Self-hosting means you control your backend fully [OK]

Common Mistakes:

• Thinking self-hosting means no maintenance needed
• Assuming self-hosting is always free
• Confusing self-hosting with automatic scaling

2. Which command is used to start Supabase services using Docker Compose?

easy

A. supabase start

B. docker compose up -d

C. docker start supabase

D. docker run supabase

Solution

1. Step 1: Identify Docker Compose usage

   Supabase self-hosting uses Docker Compose to manage multiple services together.

2. Step 2: Recall correct Docker Compose command

   The command to start services in detached mode is docker compose up -d.

3. Final Answer:

   docker compose up -d -> Option B

4. Quick Check:

   Start services with docker compose up -d [OK]

Hint: Use 'docker compose up -d' to start all services [OK]

Common Mistakes:

• Using 'docker start' which starts single containers only
• Typing 'supabase start' which is not a Docker command
• Using 'docker run' which runs a new container, not compose

3. Given this Docker Compose snippet for Supabase services:

services:
  db:
    image: supabase/postgres:latest
  api:
    image: supabase/api:latest
    depends_on:
      - db

What happens if you run docker compose up?

medium

A. Both db and api services start, with api waiting for db.

B. Only db service starts, api is ignored.

C. api starts before db, causing errors.

D. No services start due to missing volumes.

Solution

1. Step 1: Understand depends_on behavior

   The depends_on means api waits for db container to start before launching.

2. Step 2: Analyze docker compose up effect

   Running docker compose up starts all defined services; api waits for db as specified.

3. Final Answer:

   Both db and api services start, with api waiting for db. -> Option A

4. Quick Check:

   depends_on makes api wait for db [OK]

Hint: depends_on ensures service start order in Docker Compose [OK]

Common Mistakes:

• Thinking depends_on delays start until db is ready (it waits only for start)
• Assuming api won't start without volumes (not required here)
• Believing only one service starts by default

4. You tried to start Supabase with Docker Compose but get a database connection error. Which fix is most likely correct?

medium

A. Change the Supabase API image to an older version.

B. Remove the Docker Compose file and reinstall Docker.

C. Check if the database service is running and accessible.

D. Disable the firewall on your local machine.

Solution

1. Step 1: Identify cause of connection error

   Database connection errors usually mean the database service is down or unreachable.

2. Step 2: Verify database service status

   Check if the database container is running and network settings allow access.

3. Final Answer:

   Check if the database service is running and accessible. -> Option C

4. Quick Check:

   Database connection error = check DB service [OK]

Hint: Verify database container is running first [OK]

Common Mistakes:

• Assuming reinstalling Docker fixes connection errors
• Changing API image without checking DB status
• Disabling firewall without confirming network issues

5. You want to secure your self-hosted Supabase database. Which practice is best to protect your data?

hard

A. Use strong passwords, restrict network access, and enable SSL connections.

B. Run the database on default ports and allow all IPs.

C. Disable authentication to simplify access for developers.

D. Store database backups on the same server without encryption.

Solution

1. Step 1: Identify security best practices

   Strong passwords, network restrictions, and SSL protect data from unauthorized access.

2. Step 2: Evaluate other options

   Default ports and open IPs increase risk; disabling auth or unencrypted backups are unsafe.

3. Final Answer:

   Use strong passwords, restrict network access, and enable SSL connections. -> Option A

4. Quick Check:

   Secure DB = strong passwords + network + SSL [OK]

Hint: Secure DB with passwords, network limits, and SSL [OK]

Common Mistakes:

• Leaving default ports open to the internet
• Disabling authentication for convenience
• Not encrypting backups or storing them insecurely
