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? https://ochagavia.nl/blog/using-s3-as-a-container-registry/ Wed, 03 Jul 2024 00:00:00 +0000 https://ochagavia.nl/blog/using-s3-as-a-container-registry/ For the last four months I’ve been developing a custom container image builder, collaborating with Outerbounds1. The technical details of the builder itself might be the topic of a future article, but there’s something surprising I wanted to share already: you can use S3 as a container registry! You heard it right. All it takes is to expose an S3 bucket through HTTP and to upload the image’s files to specific paths. https://ochagavia.nl/blog/crafting-container-images-without-dockerfiles/ Mon, 06 Feb 2023 00:00:00 +0000 https://ochagavia.nl/blog/crafting-container-images-without-dockerfiles/ Last month I have been developing a Rust tool to create container images from Conda environments, without going through Docker. It was a wild trip down the rabbit hole of OCI images, so I thought I’d share part of the adventure here. Enjoy! But why? If you are used to building container images, you might be asking yourself why on earth someone would want to deviate from the well-trodden path of Dockerfiles.
