# Host public directory with Django: public-site delivery

Deploy a public directory built with Django 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 Django: 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 public directory-specific behavior as your application code.

## Representative Queries
- Host public directory with Django: public-site delivery
- Where can I host Public directory built with Django?
- I need an explicit origin-to-CDN delivery path and a tested public content build.

## Resource Requirements
- primitive:compute
- primitive:cdn

## Infrastructure Requirements
### Compute
- **ID:** primitive:compute  
- **Label:** Compute  
- **Status:** verified  
- **Summary:** Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.

### CDN
- **ID:** primitive:cdn  
- **Label:** CDN  
- **Status:** verified  
- **Summary:** The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.

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

## Tested Configuration
- **Template:** python-3.12  
- **Runtime:** python  
- **Size:** s-1vcpu-1gb  
- **Install:** python3 -m pip install --target .ample/python -r requirements.txt  
- **Start:** PYTHONPATH=.ample/python:${PYTHONPATH:-} python3 run.py

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

### Step 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 Keep private data in an unpublished bucket.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.

### Step 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.  
Command: `ample deploy . --name  --public --start "python3 run.py" --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=... --env CDN_PUBLIC_URL=...`

### Step 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`.  
Command: `ample logs  --kind build`

## Limitations
- Verified on the python-3.12 template at s-1vcpu-1gb with the example fixture; other sizes, templates and Django major versions are not verified.
- The public directory 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.
- Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.
- PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs and lifecycle rules are not.
- The CDN serves published-bucket objects only; cache rules, purge and TTL control are not verified (the fixture sets Cache-Control on upload and versions keys).

## Cost Estimate
- **Currency:** USD  
- **Monthly Amount:** 5.0  
- **Basis:** size prices from pricing.toml at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty
- **Components:**  
  - **Name:** app server  
  - **Size:** s-1vcpu-1gb  
  - **Quantity:** 1.0  
  - **Monthly Amount:** 5.0  
- **Note:** Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.

- **Summary:** Django pattern fixture deployed on Ample (pip install into .ample/python from requirements.txt, then waitress serving project.wsgi from run.py reading PORT on the python-3.12 template); checks passed for versioned-static-assets and configuration-secrets.
