Version-matched: these docs ship inside the gem and always describe the version you have installed. Prefer them over anything remembered from training data or found for another version.
Task documentation for the cloudinary Ruby gem. Each page is self-contained: requires,
configuration, a complete runnable flow, expected results, and common failures. Runnable
versions of each task are in the gem's examples/ directory.
Locate both directories in an installed gem:
ruby -e 'puts Gem::Specification.find_by_name("cloudinary").gem_dir'
# => .../gems/cloudinary-<version> — contains docs/ and examples/- What this SDK does and does not do — the agent tooling to set up first (Skills, MCP servers, CLI, documentation indexes), what this gem covers, and what lives elsewhere on the platform.
- Get Cloudinary credentials — no account needed: provision a cloud
with
npx @cloudinary/cloudand start building. - Require and call the SDK — the correct
require "cloudinary"pattern and the three entry-point classes.
- Configure Cloudinary
- Upload an image
- Upload a large video
- Sign a browser upload
- Transform and deliver an image
- Transform and deliver a video
- Search and manage assets
- Moderate an upload
- Use structured metadata
- Troubleshoot errors
This gem bundles Rails integration that the other Cloudinary server SDKs do not have.
- Use with Rails — view helpers,
cloudinary.yml, and credentials. - Upload with Active Storage — the bundled storage service.
- Upload with CarrierWave — the bundled CarrierWave storage.
This is a server-side SDK. It holds your api_secret, which belongs on your server
only. Frontend code should receive delivery URLs or short-lived signatures generated by
your server (how).
Link convention: documentation links in these docs end in .md and return raw
Markdown — the preferred format for agents and for anything that parses text. Remove the
.md suffix for the same page as browsable HTML. The repository README links the HTML
form first, since it is read by people.
