How to Build a Container Registry

Containers are integral to modern application deployment, whether utilizing Kubernetes or serverless architectures, with Docker Hub commonly used for storing images. However, using a personal registry can provide more control and security, as Docker Hub may not always yield consistent images and could expose vulnerabilities. The text explores setting up container registries across major cloud providers—AWS, Azure, and Google Cloud—detailing the process of creating a repository, building Docker images, and pushing them to these registries. Each cloud provider offers unique services but supports Docker or OCI-compliant images, with examples demonstrating the configuration of repositories, implementation of security policies, and management of image lifecycles. The guide emphasizes the importance of securing container images and managing cloud resources effectively using tools like Pulumi, highlighting the need for familiarity with each provider's specific offerings and configuration methods.
