Supabase provides a full-stack development platform based on PostgreSQL, integrating real-time database, identity verification, auto-generated APIs, Cloud Object Storage (COS), and edge functions. It possesses ready-to-use real-time data sync, fine-grained permission control, and Serverless scaling capability, supporting developers to quickly build AI-integrated modern applications while maintaining full control over SQL and the open-source ecosystem. For more detailed Supabase features, refer to official documentation.
This document will guide you to quickly deploy Supabase, configure connection to TencentDB for PostgreSQL as the backend database, and rapidly build your application.

Environment Preparation

You need to first create a CVM instance and a TencentDB for PostgreSQL instance under the same VPC network.

Pulling Supabase Code

# Get the code
git clone --depth 1 https://github.com/supabase/supabase

# Make your new supabase project directory
mkdir supabase-project

# Tree should look like this
# .
# ├── supabase
# └── supabase-project

# Copy the compose files over to your project
cp -rf supabase/docker/* supabase-project

# Copy the fake env vars
cp supabase/docker/.env.example supabase-project/.env

# Switch to your project directory
cd supabase-project

# Pull the latest images
docker compose pull

Modifying the Env File

Modify the following items in the supabase-project/.env file. Please ensure the corresponding account has been created in the TencentDB for PostgreSQL instance.
POSTGRES_HOST=TencentDB for PostgreSQL instance vip
POSTGRES_DB=postgres
POSTGRES_USER=supabase_admin
POSTGRES_PORT=5432
POSTGRES_PASSWORD=TencentDB for PostgreSQL Instance Account Password

Modifying the Docker-Compose.Yml File

Modify the supabase-project/docker-compose.yml file, search for the external Postgres database keyword. There is a note in the file: if using an external PG, comment out the corresponding part.
depends_on:
      # db:
        # Disable this if you are using an external Postgres database
        # condition: service_healthy

Creating Objects in TencentDB for PostgreSQL

Before pulling up Supabase, we need to create some objects (user, database, schema), otherwise lead to unable to pull up Supabase. Here the password should match the POSTGRES_PASSWORD.
CREATE USER supabase_admin pg_tencentdb_superuser password 'your password';
CREATE DATABASE _supabase;
create schema _analytics;

Purging Cache

If Supabase was not started before, no need to execute this step.
# Stop docker and remove volumes:
docker compose down -v
# Remove Postgres data:
rm -rf volumes/db/data/


Starting Up Supabase

After the above configurations are completed, Supabase is bootable.
docker compose up -d


Logging in to the Supabase Interface

Access the following link for the virtual machine instance's public IP: http://[public IP]:8000/. The Initialize Account Password is provided by Supabase.
