The article describes DigitalOcean's experience with Docker registries, highlighting the need for improved performance and availability. The company initially used a single server running the official Docker registry, but as their use of containers grew, they encountered performance issues such as slow or failing image pushes. To address these issues, they redesigned their Docker registry architecture to take advantage of Kubernetes primitives like scaling deployments and simple rolling deploys. They achieved this by disabling redirects in the registry, creating a caching proxy with Squid, and directing clients to request Docker images from the local region's registry instance using a DNS zone. This new setup has provided much quicker pulls and pushes across all data centers, enabling larger deploys and higher pull performance. Future improvements are planned, including metrics instrumentation and monitoring, as well as creating a shared regional cache for their registry deployments.
