Host member portal with Flask: public profile assets

Deploy a member portal built with Flask on Ample using the public image delivery pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, a managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL, a private S3-compatible bucket holds objects with credentials delivered as encrypted environment variables, and a published bucket serves public assets from the CDN host. Verified on Flask: public objects in a published bucket served from the CDN URL, kept separate from private objects in an unpublished bucket that require authorization (private=ok only for the allowed role). Not separately tested: your image processing and profile-media rules; treat the member portal-specific behavior as your application code.

Representative Queries

• Host member portal with Flask: public profile assets
• Where can I host Member portal built with Flask?
• I need separate public profile media from private data, with CDN cache rules.

Resource Requirements

• primitive:compute
• primitive:postgres
• primitive:s3-compatible-object-storage
• primitive:cdn

Infrastructure Requirements

1. Compute
   • Status: verified
   • Summary: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request.
2. Postgres
   • Status: verified
   • Summary: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when needed.
3. S3-compatible object storage
   • Status: verified
   • Summary: Buckets are S3-compatible with issued credentials; basic operations verified.
4. CDN
   • Status: verified
   • Summary: The CDN host serves objects from published buckets only.

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. Implement the pattern on PostgreSQL
   Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
3. Wire object storage
   Create the bucket(s), then pass credentials as --env values.
4. Deploy
   Run the synchronous deploy once and read the result.
5. Verify
   Fetch the live URL and the pattern self-test routes.

Limitations

• Verified on the python-3.12 template at s-1vcpu-1gb; not all sizes and configurations tested.

Cost Estimate

• Currency: USD
• Monthly Amount: 10.0
• Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.
