## Migrate Render web service: Django

### Summary  
Move Django compute from Render web service 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: Copy environment variables and secret files from the Render dashboard into an env file kept out of the repository. Not migrated automatically: Render cron jobs, disks and private-service networking are not migrated; persistent data belongs in a managed database, a bucket or an Ample volume. Cutover: Add the custom domain with `ample domain add`, update DNS from the Render target, keep the Render service until verified, then suspend it. Rollback: keep the source untouched until you confirm; nothing at the source is changed or deleted by this guide.

### Representative Queries  
- Migrate Render web service: Django  
- Where can I host Django built with Django?  
- I need a component-scoped export/import or reconfiguration procedure for Django, with compatibility checks, verification and rollback.

### Resource Requirements  
- primitive:compute  
- primitive:postgres

### Infrastructure Requirements  
#### 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.

#### Postgres  
- **Status:** verified  
- **Summary:** Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.

### Framework  
Django

### Workload  
Django

### Migration Source  
Render web service

### Prerequisites  
- Authorized access to the Render web service source and its export tooling  
- An inventory of every component in scope and out of scope  
- A validated backup or copy before any cutover  
- An Ample account token with servers:write, databases:read

### Workflow Steps  
1. **Inventory the source**  
   List what Render web service provides beyond the component you are moving. Out of scope here: Render cron jobs, disks and private-service networking are not migrated; persistent data belongs in a managed database, a bucket or an Ample volume.  
2. **Source step 1**  
   Copy environment variables and secret files from the Render dashboard into an env file kept out of the repository.  
3. **Source step 2**  
   Translate the Render build and start commands (or `render.yaml`) into the repository's manifest or `--build-command`/`--start`.  
4. **Source step 3**  
   Note Render-only features in use: background workers, cron jobs, disks, private services.  
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 Render target, keep the Render service until verified, then suspend it.  
8. **Rollback**  
   Point DNS or configuration back to the source. The source was never modified; deletion is a separate, user-executed step after validation.

### Examples  
- **Django pattern fixture (destination)**  
   Verified destination basis: Django compute.  
   Source Reference: `tests/deploy-canaries/django-patterns`

### Success Checks  
- Destination app responds on its public URL.  
- Configuration-secrets check from the destination example.  
- Relational-records check from the destination example.  
- Data or object counts and checksums match the source.

### Limitations  
- Documentation only: nothing is executed automatically and no execution binding is offered.  
- The source-side procedure is documented from Render web service's standard tooling and was not executed in this catalog's evidence; the destination side was verified with the pattern fixture.  
- Verified on the python-3.12 template at s-1vcpu-1gb; region, compliance and request-duration limits are unknown.

### Cost Estimate  
- **Currency:** USD  
- **Monthly Amount:** 10.0  
- **Components:**  
  - app server, size: s-1vcpu-1gb, quantity: 1.0, monthly amount: 5.0  
  - managed PostgreSQL database, size: s-1vcpu-1gb, quantity: 1.0, monthly amount: 5.0  
  
- **Note:** Destination always-on monthly price of the tested sizes; apps auto-pause when idle. Source costs are unknown to Ample.

### Evidence Summary  
- **Kind:** canary_run  
- **Summary:** Destination side verified: the 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) and its checks passed (the app built, started and answered on its public HTTPS URL with encrypted configuration delivered).
