Host Partner Portal with Spring Boot: Public Profile Assets
Deploy a partner portal built with Spring Boot 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on Spring Boot: public objects in a published bucket served from the CDN URL, kept separate from private objects in an unpublished bucket that require authorization (private=ok only for the allowed role).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 partner portal-specific behavior as your application code.
Representative Queries
- Host partner portal with Spring Boot: public profile assets
- Where can I host Partner portal built with Spring Boot?
- 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
Compute
- Canonical Path: /discover/primitive/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.
Postgres
- Canonical Path: /discover/primitive/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.
S3-compatible Object Storage
- Canonical Path: /discover/primitive/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.
CDN
- Canonical Path: /discover/primitive/cdn
- Status: verified
- Summary: The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.
Prerequisites
- A Spring Boot project that builds and starts with the documented commands (./mvnw -q -DskipTests package (or the Gradle wrapper) producing one application jar, then java -jar on the jvm-21 template (Temurin JDK 21) with server.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 and a second, published bucket for public assets (CDN_*) - An Ample account token with servers:write, databases:read, buckets:read
Workflow Steps
Build and Start
./mvnw -q -DskipTests package(or the Gradle wrapper) producing one application jar, thenjava -jaron the jvm-21 template (Temurin JDK 21) with server.port read from PORT. The server must bind 0.0.0.0 on PORT.Implement the Pattern on PostgreSQL
The fixture's module implements public image delivery: 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). 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. Publish only the bucket that serves public assets and reference its CDN URL.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=... --env CDN_PUBLIC_URL=...Verify
Fetch the live URL and the pattern self-test route(s) (/p/public-media-library, /p/private-document-library) from the example; then run your own checks. On failure readample logs --kind buildthen--kind runtime.ample logs --kind build
Success Checks
- App responds on its public URL
- Public-media-library self-test
- Private-document-library self-test
Limitations
- Verified on the jvm-21 template at s-1vcpu-2gb with the example fixture; other sizes, templates and Spring Boot major versions are not verified.
- The partner portal itself (your image processing and profile-media rules) is application code and was not separately tested; the pattern checks are what was verified.
- Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.
Cost Estimate
- Currency: USD
- Monthly Amount: 10.0
- Components:
- App server: s-1vcpu-1gb (1.0, 5.0)
- Managed PostgreSQL database: s-1vcpu-1gb (1.0, 5.0)
- Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.
