Host recruiting tracker with Quarkus: private attachments
Deploy a recruiting 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 recruiting tracker-specific behavior as your application code.

- Where can I host Recruiting tracker built with Quarkus?
- I need attachment metadata, access checks and a tested private object access path.
Resource Requirements

- primitive:postgres
- primitive:s3-compatible-object-storage
Infrastructure Requirements
| Primitive ID | Label | Canonical Path | Status | Summary |
|---|---|---|---|---|
| primitive:compute | Compute | /discover/primitive/compute | verified | Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes. |
| primitive:postgres | Postgres | /discover/primitive/postgres | verified | Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied. |
| primitive:s3-compatible-object-storage | S3-compatible object storage | /discover/primitive/s3-compatible-object-storage | verified | Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified. |
Prerequisites
- A Quarkus project that builds and starts with the documented commands (./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)
- A PostgreSQL driver reading DATABASE_URL at runtime (auto-provisioned when omitted, or supplied with --env)
- A bucket from
ample bucket createwith its credentials passed as encrypted S3_* environment variables - An Ample account token with servers:write, databases:read, buckets:read
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.Command: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 readample logs --kind buildthen--kind runtime.
Command:ample logs --kind build
Success Checks
- app responds on its public URL
Kind: http_get; Path: /; Expect: ample canary quarkus patterns - private-document-library self-test
Kind: http_get; Path: /p/private-document-library; Expect: private=ok (with ?role=owner; 401 without, 403 for viewer)
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 recruiting 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 verified.
