Host knowledge base with Next.js: object-stored public media
Deploy a knowledge base built with Next.js on Ample using the public media 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, and a published bucket serves public assets from the CDN host. Verified on Next.js: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly. Not separately tested: your media processing, object layout and cache policy; treat the knowledge base-specific behavior as your application code.
Representative Queries
- Host knowledge base with Next.js: object-stored public media
- Where can I host Knowledge base built with Next.js?
- I need an object layout, public asset URL policy and CDN delivery configuration.
Prerequisites
- A Next.js project that builds and starts with the documented commands (
next buildthennext start -H 0.0.0.0 -p $PORTon the node-22 template) - A PostgreSQL driver reading
DATABASE_URLat runtime (auto-provisioned when omitted, or supplied with --env) - A bucket from
ample bucket createwith its credentials passed as encryptedS3_*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
next buildthennext start -H 0.0.0.0 -p $PORTon the node-22 template. The server must bind0.0.0.0onPORT.Implement the pattern on PostgreSQL
The fixture's module implements public media library: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly. 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--envvalues. 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 Keep private data in an unpublished bucket.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) 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
Limitations
- Verified on the node-22 template at
s-1vcpu-1gbwith the example fixture; other sizes, templates and Next.js major versions are not verified. - The knowledge base itself (your media processing, object layout and cache policy) 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.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified; apps and their databases are placed together.

Evidence Summary
- Next.js pattern fixture deployed on Ample; checks passed for public-media-library and configuration-secrets.
- The same Next.js app deployed with a
--release-commandmigration; the marker it created was readable after activation.
