Containerization offers isolated and reproducible build and runtime environments in a simple and developer-friendly form.

We also use containers for CI/CD in our build systems, and locally for development. In this post, I’ll describe how we redesigned our Docker registry architecture for better performance.

This is a common, simple pattern for private registries, and it worked well early on. By relying on a consistent object store for backing storage, the registry itself doesn’t have to worry about consistency. However, with a single registry instance, there are still performance and availability bottlenecks, as well as a dependency on being able to reach the region running the registry.","spans":[]},{"type":"paragraph","text":"As our use of containers grew, we started to experience general performance issues such as slow or failing image pushes. A simple solution for this would be to increase the number of registry instances running, but we’d still have a dependency on the single region being available and reachable from every server.","spans":[]},{"type":"paragraph","text":"Additionally, the default behavior of the official Docker registry is to serve the actual image data via a redirect to the backing store. This means a request from a client arrives at the registry server, which returns a HTTP redirect to object storage (or whatever remote backend you have configured the registry to use). One unique issue that we encountered was a large deployment of large Docker images (~10GB) spiking bandwidth to our storage backend. Hundreds of clients requested a new, large image at the same time, saturating our connection to storage from our data center. Running multiple instances of the registry wouldn’t solve this issue—all the data would still come from the backing store.","spans":[]},{"type":"heading2","text":"Design goals","spans":[]},{"type":"paragraph","text":"We decided it was time to to overhaul our Docker registry architecture, with a few primary goals in mind:","spans":[]},{"type":"list-item","text":"Presence in every region","spans":[]},{"type":"list-item","text":"Regional caching to reduce the overall bandwidth egress from any region","spans":[]},{"type":"list-item","text":"Reduction or elimination of single points of failure","spans":[]},{"type":"heading2","text":"Architecture choices","spans":[]},{"type":"paragraph","text":"We operate relatively large Kubernetes clusters in every DigitalOcean region, so using the fundamental building blocks that Kubernetes and our customizations offer was a logical choice.

Disabling redirection causes the registry server to retrieve image data, and then send it directly to the client, instead of redirecting the request to the backend store.

This means that in a deployment of multiple instances, multiple identical requests directed to different backing instances could result in several cache misses, one for each instance of the registry and cache. There's room for future improvement here, setting up a larger, shared cache that all registry instances in a region sit behind.
