Docker & Portainer

Build​

docker build -t magic-labs .

The dockerfile at the repo root handles the Next.js production build.

Persistent volume​

public/assets/uploads/ must be mounted as a persistent volume — uploaded files are written here at runtime and are NOT in the image.

In docker-compose.yml:

volumes:
  - uploads:/app/public/assets/uploads

Without this, uploaded files are lost on every container restart.

nginx​

Config lives in nginx/ — handles proxying to the Next.js container.

Environment variables​

Set all env vars in Portainer (stack environment variables), not in .env files committed to git.

See Environment Variables for the full list.
