In-Browser Container Builds
Containers are fun. The ecosystem is incredibly open, with the internals right there for anyone to explore. Once you wrap your head around the specifications, you unlock the power to build custom tools and may even discover unexpected use cases1. Speaking of “unexpected use cases”, today I have a demo to share: a web application that builds containers right in your browser, relying only on client-side code. Try it out Seeing is believing, so why don’t you head to the demo and build a container?
AI Summary
The article presents a web-based demonstration of building container images entirely within a browser using client-side code, showcasing that container images are simply manipulable file sets that don't require traditional server-side tools. While the author acknowledges this is primarily a research prototype and "gimmick," they argue that custom container tooling can unlock significant practical benefits, such as dramatically reducing image creation times from hours to seconds. The piece emphasizes that understanding container internals enables developers to build innovative custom tools beyond standard approaches like Docker.
