Best Container Registries

Google Cloud Platform provides Container Registry, a fully-managed solution for storing and managing Docker container images. This service ensures secure and scalable storage, seamlessly integrating with Google Kubernetes Engine and other tools. New customers receive $300 in free credits to run, test, and deploy workloads, allowing them to explore the benefits of using Container Registry for managing their container images and deploying applications in a secure environment. The platform offers fine-grained access control, ensuring that only authorized users can push, pull, or delete images, which enhances the security of containerized applications. Container Registry also supports vulnerability scanning, helping businesses identify potential security risks in their container images. This service allows companies to streamline the management of their containerized applications while maintaining robust security.

8gears Container Registry is a Harbor-based container registry as a service offered and operated by the project's maintainer and contributors. For organizations, and software vendors looking for ways to distribute software as container images.

CNCF Harbor is an open-source project that enhances container registry capabilities with a focus on security and compliance. It builds upon basic registry functionality by offering features such as vulnerability scanning to identify known security weaknesses in images, role-based access control for granular image access management, image signing to ensure authenticity and prevent tampering, and replication for efficient syncing of images across multiple other registries. Harbor strengthens the security of the image management process. It can be particularly beneficial for organizations that prioritize security and compliance in their containerized environments. However, users should be aware that setting up and maintaining Harbor can require additional effort and expertise compared to simpler container registries. 

Docker images are placed in fault-tolerant storage. Automatic replication is configured for all data, each replica changes when Docker images are edited, created, or deleted. The service provides containers for Linux and Windows OS. Use them however you want, running on your local machine or on a Yandex Compute Cloud VM. High-speed Docker image operations without expenses for external traffic, Docker image registries are hosted in the same data centers where your cloud infrastructure is deployed. Docker images are transmitted via HTTPS. You choose who can view, pull, push, or delete them. You use a Docker image and we take care of maintaining the infrastructure where your registry is running. You only pay for the space used by your Docker images. You can use the service via the management console, command line interface (CLI), API, or the standard Docker CLI, the service is compatible with the Docker registry HTTP API V2.

Store and distribute container images in a fully managed private registry. Push private images to conveniently run them in the IBM Cloud® Kubernetes Service and other runtime environments. Images are checked for security issues so you can make informed decisions about your deployments. Install the IBM Cloud Container Registry CLI to use the command line to manage your name spaces and Docker images in the IBM Cloud® private registry. View information about potential vulnerabilities and the security of images in the IBM Cloud Container Registry public and private repositories with the IBM Cloud console. Check the security status of container images that are provided by IBM, third parties or that are added to your organization's registry namespace. Advanced capabilities for security compliance insight. Access controls and image signing capabilities. Pre-integration with Kubernetes Service.
