Django-OCI vs KakaoCloud Container Registry

Django-OCI is free, open-source software for Python developers building registries that follow the OpenContainers Distribution Specification. The Django module exposes API endpoints for pushing, pulling, and interacting with container images, and can run in a virtual environment or within a container-orchestrated registry. Installation is available through pip or a GitHub checkout and includes Django Rest Framework. Filesystem storage is the default option, intended for smaller registries without external cloud storage. Authentication uses a Docker-style OAuth 2.0 flow with username and account-token credentials plus JWT access tokens. Configuration covers URL prefixes, specification version, content types, storage, authentication, token and session expiry, request limits, and manifest-tag deletion. There is no frontend for viewing containers. Private repositories and repository ownership or contributors are not implemented. The project is described as early development, with most goals still under development. Python tests and distribution-spec conformance testing are documented. Developers are asked to consider GDPR compliance, open an issue for help, and review the project license before use.

KakaoCloud Container Registry is a managed cloud repository for storing and managing Docker container images. It supports standard Docker images and Docker CLI authentication, push, and pull workflows, and integrates with KakaoCloud Kubernetes Engine for managing and deploying images. IAM roles separate repository members, who can push and pull, from viewers, who can pull only. Trivy scans for CVE-based vulnerabilities, either daily or automatically after images are pushed. Users can review image and tag history and recover earlier image versions or deleted tags. Public repositories let KakaoCloud-authenticated users who know the URI pull without separate repository authentication. Default quotas are 1,000 repositories per project, 10,000 images per repository, and 1,000 tags per image; increases can be requested. Storage up to 1 GiB is free; usage beyond that costs 0.14 won per GiB/hour. Outbound traffic includes 30 GiB free; higher usage is billed by tier. The listed plan prices are free for storage and outbound traffic, with VAT excluded.
