Docker Hub vs Quay.io: What are the differences?
Docker Hub and Quay.io are both container registries that allow users to store and distribute their Docker images. Let's explore the key differences between them.
Pricing and Plans: Docker Hub offers both free and paid plans, with the paid plans providing additional features such as increased storage and automated builds. Quay.io, on the other hand, offers only paid plans with a focus on enterprise-grade features such as advanced image vulnerability scanning and container signing.
User Interface and Experience: Docker Hub provides a user-friendly and intuitive interface, making it easier for users to navigate and manage their repositories and images. Quay.io, on the other hand, offers a more simplistic interface but provides advanced features like the ability to link repositories and use repositories as dependencies for easy image promotion.
Security Features: Docker Hub focuses on providing basic security features such as image scanning for vulnerabilities and the ability to enforce image signing and verification. Quay.io, on the other hand, offers advanced security features like content trust, which allows users to verify the images' authenticity on their local systems before running them.
Integration and Extensibility: Docker Hub is tightly integrated with the Docker ecosystem and provides seamless integration with Docker Engine and Docker Desktop. Quay.io, on the other hand, is more extensible and can be integrated with other container orchestration platforms like Kubernetes. It also offers a REST API and webhooks for automation and integration with other systems.
Private Image Catalogs: Docker Hub allows users to create private repositories and control access to their Docker images using user permissions. Quay.io, on the other hand, provides more fine-grained control over access to images by allowing users to create organizations and teams with different access levels to repositories.
Community and Marketplace: Docker Hub has a large and active community of users, making it easy to find and share Docker images. It also has a marketplace where users can find pre-built Docker images for popular applications. Quay.io, on the other hand, has a smaller community but offers a curated set of images for enterprise applications and enforces stricter image quality and security controls.
In summary, Docker Hub is a more user-friendly and widely used container registry with a larger community and marketplace, while Quay.io offers more advanced enterprise-grade features, extensibility, and fine-grained access control.
