The record

Purpose: The project provides a container registry implementation in Cloudflare Workers backed by R2.
Push and pull: It supports container image pushing and pulling workflows.
Authentication: It supports username/password and public-key JWT authentication.
Docker: The README shows using Docker login, push, and pull with the registry.
Registry fallback: It can fetch images missing from its R2 bucket from another registry and copy them into R2 for later pulls.
Fallback authentication: Pull fallback supports Basic and Bearer authentication.
Deployment: The deployment instructions configure a Cloudflare Worker and an R2 bucket using Wrangler.
Credential handling: The README directs users to store registry passwords and tokens as Wrangler secrets rather than in the Wrangler configuration file.
JWT scope: The README says JWT tokens have no per-account or per-repository scoping, and a verified token grants its capabilities across the whole registry.
Push size limit: Docker pushes are limited to images whose layers are at most 500MB, with the README referring to Workers plan request body limits.
Dependency support: The README says pnpm is the only supported package manager, though other package managers may work.
License: The repository is licensed under the Apache License 2.0.
Security reporting: The repository security policy directs vulnerability reports to Cloudflare's disclosure program or [email protected].
Free R2 allowance: Cloudflare R2 includes 10 GB-month of Standard storage, 1 million Class A requests, and 10 million Class B requests each month at no charge.
