### Host project tracker with Quarkus: private attachments

Deploy a project tracker built with Quarkus on Ample using the private document library 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. Verified on Quarkus: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). Not separately tested: your identity integration and role assignments; treat the project tracker-specific behavior as your application code.

#### Representative Queries
- Host project tracker with Quarkus: private attachments
- Where can I host Project tracker built with Quarkus?
- I need attachment metadata, access checks and a tested private object access path.

#### Resource Requirements
- **Primitive:** compute
- **Primitive:** postgres
- **Primitive:** s3-compatible-object-storage

#### Infrastructure Requirements
1. **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.

2. **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.

3. **S3-compatible object storage**  
   - **Status:** verified  
   - **Summary:** Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

#### Workflow Steps
- **Build and start**  
  `./mvnw -q -DskipTests package producing one uber-jar (quarkus.package.jar.type=uber-jar), then java -jar on the jvm-21 template (Temurin JDK 21) with quarkus.http.port read from PORT. The server must bind 0.0.0.0 on PORT.`

- **Implement the pattern on PostgreSQL**  
  `The fixture's module implements private document library: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.`

- **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.`

- **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 --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...`

- **Verify**  
  `Fetch the live URL and the pattern self-test route(s) (/p/private-document-library) from the example; then run your own checks. On failure read `ample logs  --kind build` then `--kind runtime`.`  
  `ample logs  --kind build`

#### Examples
- **Quarkus pattern fixture**  
  - **Description:** Multi-pattern Quarkus app whose private document library module was checked live; the module is under tests/deploy-canaries/_pattern-modules.
  - **Source Reference:** tests/deploy-canaries/quarkus-patterns

#### Limitations
- Verified on the jvm-21 template at s-1vcpu-2gb with the example fixture; other sizes, templates and Quarkus major versions are not verified.
- The project tracker itself (your identity integration and role assignments) 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.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified; apps and their databases are placed together.
- PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs and lifecycle rules are not.

#### Cost Estimate
- **Currency:** USD  
- **Monthly Amount:** 10.0  
- **Authoritative:** true  
- **Basis:** size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty  
- **Components:**  
  1. **App server:**  
     - **Size:** s-1vcpu-1gb  
     - **Quantity:** 1.0  
     - **Monthly Amount:** 5.0  
  2. **Managed PostgreSQL database:**  
     - **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.
