Creating a custom Docker registry

In a detailed exploration of Docker's push and pull processes, Matthew Casperson presents a practical guide to implementing a minimal Docker registry using C#. By building a server that responds to Docker's V2 HTTP API specification, the article demonstrates the paths necessary for handling image layers and manifests, highlighting the intricacies of Docker image management. The guide walks through the steps to create endpoints for pushing and pulling Docker images, covering API interactions such as initiating uploads, handling chunked data, and managing manifests. While the implementation is not suited for production, it provides valuable insight into the mechanics behind Docker's operations, including aspects of layer and manifest handling. Casperson's approach aims to demystify Docker's API for developers and offers a foundation for further exploration into Docker integration and custom registry solutions.
