Host CSV Import Tool with Rails: Structured Data Imports

Deploy a CSV import tool built with Rails on Ample using the bulk import staging 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 Rails: a CSV staged as an object, row-level validation with per-row errors recorded, and a restart-safe import keyed by import id (imported=2 rejected=1 restart=ok). Not separately tested: your import format, mapping and conflict rules; treat the CSV import tool-specific behavior as your application code.

Summary

Input Schema

{
  "env": ["string"],
  "name": "string",
  "path": "string",
  "release_command": "string"
}

Prerequisites

  1. A Rails project that builds and starts with the documented commands.
  2. A PostgreSQL driver reading DATABASE_URL at runtime.
  3. A bucket from ample bucket create with its credentials passed as encrypted S3_* environment variables.
  4. An Ample account token with servers:write, databases:read, buckets:read.

Workflow Steps

  1. Build and start: bundle install and start the server.
  2. Implement the pattern on PostgreSQL: Create the bulk import staging module in your schema.
  3. Wire object storage: Pass endpoint, region, bucket, and keys as environment values.
  4. Deploy: Run the synchronous deploy.
  5. Verify: Fetch the live URL and perform checks.
