# Host documentation site with Flask: public-site delivery

## Summary
Deploy a documentation site built with Flask on Ample using the public web service pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, and a published bucket serves public assets from the CDN host. Verified on Flask: a versioned, immutable-cached asset uploaded to a published bucket and served from the CDN URL alongside the app's own public HTTPS URL. Not separately tested: your site content and build; treat the documentation site-specific behavior as your application code.

## Prerequisites
- A Flask project that builds and starts with the documented commands (pip install into .ample/python from requirements.txt, then waitress from app.py reading PORT on the python-3.12 template)
- A bucket from `ample bucket create` with its credentials passed as encrypted S3_* environment variables
- An Ample account token with servers:write, buckets:read

## Workflow Steps
### 1. Build and start
pip install into .ample/python from requirements.txt, then waitress from app.py reading PORT on the python-3.12 template. The server must bind 0.0.0.0 on PORT.

### 2. Wire object storage
Create the bucket(s), then pass endpoint, region, bucket and keys as --env values. Use path-style addressing. Keep private data in an unpublished bucket. Publish only the bucket that serves public assets and reference its CDN URL.

### 3. Deploy
Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked). Re-running with no change is a no-op.

`ample deploy . --name --public --start "python3 app.py" --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=... --env CDN_PUBLIC_URL=...`

### 4. Verify
Fetch the live URL and the pattern self-test route(s) (/p/versioned-static-assets) from the example; then run your own checks. On failure read `ample logs --kind build` then `--kind runtime`.

`ample logs --kind build`

## Success Checks
- **App responds on its public URL**: HTTP GET on `/`, expect "ample canary flask patterns"
- **Versioned-static-assets self-test**: HTTP GET on `/p/versioned-static-assets`, expect "a CDN URL whose content is served publicly"

## Limitations
- Verified on the python-3.12 template at s-1vcpu-1gb with the example fixture; other sizes, templates and Flask major versions are not verified.
- The documentation site itself (your site content and build) is application code and was not separately tested; the pattern checks are what was verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
