Migrate DigitalOcean Droplet App: Django

Summary

Move Django compute from DigitalOcean Droplet app to Ample, one component at a time. Destination verified on Ample: the app built, started, and answered on its public HTTPS URL with encrypted configuration delivered.
Source procedure: Collect the process environment from the droplet (systemd unit, PM2 or supervisor config) into an env file kept out of the repository. Not migrated automatically: Cron jobs, local upload directories, and firewall rules are not migrated; move uploads to a bucket and data to a managed database.
Cutover: Add the custom domain with ample domain add, update DNS from the droplet IP, keep the droplet until verified, then power it off.
Rollback: keep the source untouched until you confirm; nothing at the source is changed or deleted by this guide.

Prerequisites

Workflow Steps

  1. Inventory the source
    List what DigitalOcean Droplet app provides beyond the component you are moving. Out of scope here: Cron jobs, local upload directories, and firewall rules are not migrated; move uploads to a bucket and data to a managed database.

  2. Source step 1
    Collect the process environment from the droplet (systemd unit, PM2 or supervisor config) into an env file kept out of the repository.

  3. Source step 2
    Replace the droplet's process manager and reverse proxy with the repository's start command; Ample provides HTTPS and supervision.

  4. Source step 3
    Inventory what else runs on the droplet: databases, cron, local uploads.

  5. Deploy on Ample in parallel
    pip install into .ample/python from requirements.txt, then waitress serving project.wsgi from run.py reading PORT on the python-3.12 template. Pass the exported variables with --env; keep the source running.

    Command: ample deploy . --name --public --start "python3 run.py" --env-file .env.production

  6. Validate before cutover
    Run the app's own checks and, for data, compare counts and checksums; the example checks are the pattern self-tests (/p/configuration-secrets, /p/relational-records).

  7. Cut over
    Add the custom domain with ample domain add, update DNS from the droplet IP, keep the droplet until verified, then power it off.

  8. Rollback
    Point DNS or configuration back to the source. The source was never modified; deletion is a separate, user-executed step after validation.
