Container Registry overview

KakaoCloud’s Container Registry is a private image repository service that enables secure storage and management of Docker container images in the cloud. It integrates seamlessly with KakaoCloud’s managed Kubernetes service, Kubernetes Engine, and supports efficient management and deployment of container images for container-based applications and services.

Since it is based on KakaoCloud's IAM, user access to repositories can be strictly controlled. The service is designed to optimize development and operational workflows while maintaining image stability and security, enabling successful operation of containerized applications in cloud environments. It supports standard Docker images, offering excellent compatibility and portability, along with easy version control and updates.

Terminology
  • Container image: A package of files and settings required to run a containerized application or service. It defines the runtime environment for the containerized service and is deployed using container orchestration platforms.

Purpose and use cases​

To use container images, a storage location is required. While individuals may rely on free plans from services like GitHub or DockerHub, enterprises typically require private repositories. Building an in-house repository often comes with development and operational costs.
By using KakaoCloud Container Registry, companies can save resources needed to develop new storage systems, manage images centrally, and deploy applications using the same image across multiple environments.
