Host crm with Quarkus: downloadable reports

Summary

Deploy a CRM built with Quarkus on Ample using the generated downloads 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: an export query rendered to a CSV artifact stored with metadata in a private bucket and returned only to an authorized caller (401 without token, export=ok rows=3). Not separately tested: your export formats, retention policy and entitlement model; treat the CRM-specific behavior as your application code.

Representative Queries

• Host crm with Quarkus: downloadable reports
• Where can I host CRM built with Quarkus?
• I need an export query, generated artifact retention and authorized download flow.

Resource Requirements

• Primitive Compute
• Primitive Postgres
• Primitive S3-compatible Object Storage

Infrastructure Requirements

1. Compute: 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: 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: 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 create with its credentials passed as encrypted S3_* environment variables
• An Ample account token with servers:write, databases:read, buckets:read

Workflow Steps

1. 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 with quarkus.http.port read from PORT. The server must bind 0.0.0.0 on PORT.
2. Implement the pattern on PostgreSQL: The fixture's module implements generated downloads: an export query rendered to a CSV artifact stored with metadata in a private bucket, returned only to an authorized caller (401 without token, export=ok rows=3). Copy the approach into your schema; keep migrations idempotent.
3. Wire object storage: Create the bucket(s), pass endpoint, region, bucket and keys as --env values. Keep private data in an unpublished bucket.
4. Deploy: Run the synchronous deploy once and read the result. 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=...
5. Verify: Fetch the live URL and pattern self-test route(s) from the example; then run your own checks. On failure, read ample logs --kind build then --kind runtime.
   Command: ample logs --kind build

Cost Estimate

• Monthly Amount: $10.00 USD
• Components:
  • App Server s-1vcpu-1gb: $5.00
  • Managed PostgreSQL Database s-1vcpu-1gb: $5.00
• Note: Always-on monthly price of the tested sizes; buckets are allocation-priced per quota and not included.

Limitations

• Verified on the jvm-21 template at s-1vcpu-2gb with the example fixture; other sizes and templates are not verified.
• The CRM itself (export formats, retention policy, entitlement model) is application code and was not separately tested.
• Apps auto-pause when idle, and always-on is an operator setting, not a plan feature.

Evidence Summary

• Canary Run Summary: Quarkus pattern fixture deployed on Ample, checks passed for generated-downloads and configuration-secrets. Pattern proof: an export query rendered to a CSV artifact stored with metadata returned only to authorized callers.
