Migrate DigitalOcean Spaces bucket: Tenant-scoped object prefixes

Move object storage from DigitalOcean Spaces bucket to Ample, one component at a time. Destination verified on Ample: every tenant's objects stored under tenants// in a private bucket with an ownership row per object, reads refused for keys outside the caller's prefix or not owned (cross=forbidden), and a prefix-bound listing returning only that tenant's objects (own=1). Source procedure: Inventory the Space with rclone size or s3cmd du. Not migrated automatically: Spaces CDN settings, CORS rules and per-object ACLs are not migrated; publish an Ample bucket for public delivery. Cutover: Switch the app's S3_* environment to the Ample bucket with a redeploy, verify reads and writes, keep the Space read-only until confirmed. Rollback: keep the source untouched until you confirm; nothing at the source is changed or deleted by this guide.

• Where can I host Tenant-scoped object prefixes?
• I need a component-scoped export/import or reconfiguration procedure for Tenant-scoped object prefixes, with compatibility checks, verification and rollback.

Workload

Tenant-scoped object prefixes

Resource Requirements

• S3-compatible object storage

Infrastructure Requirements

• 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

• Authorized access to the DigitalOcean Spaces bucket source and its export tooling
• An inventory of every component in scope and out of scope
• A validated backup or copy before any cutover
• An Ample account token with servers:write, buckets:write

Workflow Steps

1. Inventory the source: List what DigitalOcean Spaces bucket provides beyond the component you are moving. Out of scope here: Spaces CDN settings, CORS rules and per-object ACLs are not migrated; publish an Ample bucket for public delivery.
2. Source step 1: Inventory the Space with rclone size or s3cmd du
3. Source step 2: Copy objects with rclone sync from the Spaces endpoint to the Ample bucket endpoint using the issued credentials (path-style)
4. Source step 3: Verify a sample of objects by size and checksum after the copy
5. Create the destination bucket and copy: Create the bucket, copy with rclone or the S3 CLI in path-style mode using the issued credentials, then pass the credentials to the app as encrypted S3_* variables.
   • Command: ample bucket create --name
6. Validate before cutover: Run the app's own checks and, for data, compare counts and checksums; the example checks are the pattern self-tests (/p/tenant-scoped-object-prefixes).
7. Cut over: Switch the app's S3_* environment to the Ample bucket with a redeploy, verify reads and writes, keep the Space read-only until confirmed.
8. Rollback: Point DNS or configuration back to the source. The source was never modified; deletion is a separate, user-executed step after validation.

Examples

• Express pattern fixture (destination): Verified destination basis: tenant-scoped object prefixes.

Success Checks

• The destination app responds on its public URL
• Tenant-scoped-object-prefixes check from the destination example
• Data or object counts and checksums match the source

Limitations

• Documentation only: nothing is executed automatically and no execution binding is offered.
• The source-side procedure is documented from DigitalOcean Spaces bucket's standard tooling and was not executed in this catalog's evidence; the destination side was verified with the pattern fixture.
• No full source-product parity is claimed: Spaces CDN settings, CORS rules and per-object ACLs are not migrated; publish an Ample bucket for public delivery.

Cost Estimate

• Currency: USD
• Monthly Amount: 5.0
• Components:
  • App server: size s-1vcpu-1gb, quantity 1.0, monthly amount 5.0

Evidence Summary

• Destination side verified: the Express pattern fixture deployed on Ample and its checks passed. The source-side export from DigitalOcean Spaces bucket is documented from the vendor's standard tooling and was not executed by this catalog's evidence.
