Configure S3-compatible access for Quarkus
Summary
Object storage client for a Quarkus app on Ample. Verified on Quarkus: bucket credentials delivered as encrypted S3_* environment variables and a validated PutObject/GetObject round-trip linked to a database row (upload=ok linked=ok). 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.
Resource Requirements
- Primitive Compute
- Primitive S3-compatible Object Storage
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.
Create the bucket and pass its credentials
- Create it once with
ample bucket create, then pass endpoint, region, bucket and keys with --env; use path-style addressing. - Command:
ample deploy . --name --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
- Create it once with
Verify
- Fetch the live URL and /p/browser-file-uploads on the example; on failure read the build and runtime logs.
- Command:
ample logs --kind build
Examples
- Quarkus pattern fixture: Verified object storage client on Quarkus.

Success Checks
- App responds on its public URL

Expect:ample canary quarkus patterns - Browser-file-uploads check from the example
Path:/p/browser-file-uploads
Expect:see the pattern fixture checks
Limitations
- Verified on the jvm-21 template at s-1vcpu-2gb; other sizes and Quarkus major versions are not verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- PutObject and GetObject with path-style addressing are verified; other S3 operations are not.
Cost Estimate
- Currency: USD
- Monthly Amount: 5.0
- Basis: Size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty.
Components
- App Server:
- Size: s-1vcpu-1gb
- Quantity: 1.0
- Monthly Amount: 5.0
Note
Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.
