Supabase Self-Hosted on Ubuntu (Docker)

When to use

Use when user asks to install/run Supabase via Docker on Ubuntu server and needs DB connection for a website/backend.

Why this skill exists

Ubuntu package names for Docker Compose differ across releases. docker-compose-plugin may be unavailable even though Compose v2 is available as docker-compose-v2.

Procedure

1. Prerequisites check
   • docker --version
   • docker compose version (or fallback docker-compose version)
   • ss -lntp to check port conflicts (8000, 8443, 5432, 6543)
