@@ -60,6 +60,40 @@ This follows the same external pattern as your website container:
 
 If your server already has a host-level nginx handling domains and TLS, use `deploy/nginx/clients.lean-101.proxy.conf` as the upstream template and point the domain at `http://127.0.0.1:8081`.
 
+## Production deployment (Postgres + Digital Ocean)
+
+`docker-compose.production.yml` provisions a managed-style stack with a containerised Postgres 16 service replacing the SQLite file used in alpha. The PowerShell script `deploy/Deploy.ps1` drives both first-time bootstrap and incremental updates from a Windows workstation against a Digital Ocean droplet.
+
+1. **One-time droplet prep**: install Docker Engine + the compose plugin (`apt install docker.io docker-compose-plugin` or the official Docker repo). Open inbound 80/443 on your reverse proxy and forward to `127.0.0.1:${CLIENTS_APP_PORT}` (default 8081).
+2. **Local secrets**: copy the example env and fill in real secrets — strong `POSTGRES_PASSWORD`, `AUTH_SECRET`, `CLIENT_PASSWORD`, `ADMIN_PASSWORD`. The compose file refuses to start without them.
+
+   ```powershell
+   Copy-Item .env.production.example .env.production
+   notepad .env.production
+   ```
+
+3. **First deploy** (clones the repo on the droplet, uploads the env file, brings the stack up):
+
+   ```powershell
+   ./deploy/Deploy.ps1 `
+     -RemoteHost 203.0.113.10 `
+     -Bootstrap `
+     -RepoUrl git@github.com:ponzischeme89/data-entry-app.git `
+     -Seed
+   ```
+
+4. **Subsequent updates** (the same script — pulls latest `main`, rebuilds, and rolls containers without touching the Postgres volume):
+
+   ```powershell
+   ./deploy/Deploy.ps1 -RemoteHost 203.0.113.10
+   ```
+
+   Useful flags: `-Branch <name>` to deploy a feature branch, `-SkipBuild` for env-only changes, `-Seed` to re-run reference data seeding, `-Logs` to tail logs after the deploy, `-SshKey` to point at a specific private key.
+
+5. **Database**: the backend reads `DATABASE_URL`. The production compose file synthesises it as `postgresql+psycopg://${POSTGRES_USER}:${POSTGRES_PASSWORD}@db:5432/${POSTGRES_DB}` so you only need to set the three `POSTGRES_*` vars. Override `DATABASE_URL` directly if you point at a managed Postgres (e.g. DigitalOcean managed databases).
+
+The schema is auto-managed — `app/db/migrations.py` runs at backend startup and is idempotent across SQLite and Postgres. To migrate alpha SQLite data into the new Postgres instance, dump tables to CSV from the alpha container and import via `\copy` in `psql`; there is no automatic SQLite → Postgres path.

+<#
+.SYNOPSIS
+  Build and deploy the Lean 101 Clients app to a Digital Ocean droplet over SSH.
+
+.DESCRIPTION
+  Runs `docker compose` against `docker-compose.production.yml` on the remote
+  host. The same script handles first-time bootstrap and subsequent updates:
+
+    * On bootstrap (-Bootstrap): creates the remote directory, clones the
+      repo (or updates if already present), uploads the local env file, and
+      brings the stack up with `docker compose ... up -d --build`.
+
+    * On update (default): SSHes to the host, fetches the requested branch,
+      uploads a refreshed env file (if changed), then runs
+      `docker compose ... up -d --build` followed by a healthcheck.
+
+  The script never executes destructive commands without asking, except for
+  recreating containers (which preserves the named Postgres volume).
+
+.PARAMETER RemoteHost
+  Hostname or IP of the Digital Ocean droplet. Required.
+
+.PARAMETER RemoteUser
+  SSH user on the droplet. Defaults to `root`.
+
+.PARAMETER RemotePath
+  Absolute path on the droplet where the repo lives. Defaults to
+  `/srv/lean101-clients`.
+
+.PARAMETER Branch
+  Git branch to deploy. Defaults to `main`.
+
+.PARAMETER RepoUrl
+  Git URL used during bootstrap when the remote directory is empty.
+  Required only with -Bootstrap.
+
+.PARAMETER EnvFile
+  Local path to the env file that should land on the droplet as
+  `<RemotePath>/.env.production`. Defaults to `.env.production`.
+
+.PARAMETER SshKey
+  Optional path to an SSH private key. If omitted, the script relies on
+  ssh-agent / default keys.
+
+.PARAMETER ComposeFile
+  Compose file name on the remote host. Defaults to
+  `docker-compose.production.yml`.
+
+.PARAMETER Bootstrap
+  Run first-time setup (clone, upload env, build, up).
+
+.PARAMETER SkipBuild
+  Pass `--no-build` to docker compose (use when only env changed).
+
+.PARAMETER Seed
+  Run `python -m app.seed` inside the backend container after the stack is up.
+
+.PARAMETER Logs
+  After deploy, tail logs for ~20 lines so you can verify the stack came up.
+

+  ./deploy/Deploy.ps1 -RemoteHost 203.0.113.10 -Bootstrap -RepoUrl git@github.com:ponzischeme89/data-entry-app.git
