Cosmoner Container Registry vs KakaoCloud Container Registry

Cosmoner Container Registry is a managed private registry backed by Amazon ECR for storing container images used by apps. Developers can push and pull images from a laptop or CI system with Docker and a Cosmoner API key. Images in a project registry appear in the Apps image deployment flow, where deployments authenticate without a pull secret. Scanning on push is enabled by default and checks images against known vulnerabilities. Images use AES256 encryption by default, with a customer KMS key available for repositories created afterward. Retention settings can keep a selected number of recent images and expire untagged images after a chosen number of days. Repositories are private by default; public repositories require a monthly egress cap and revert to private when it is reached. The product lists nine regions across North America, Europe, and Asia Pacific, and a registry’s region cannot be changed after creation. Uploads are not charged; egress, storage, and a registry fee are billed separately. The registry fee is $1 a month, prorated from creation; storage is $0.25 a month per GB, and egress is $0.15 a month per GB after the first 10 GB per organization per billing period.

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.
