Using S3 as a container registry
Post details
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.

My mind is blown 🤯 In a Dockerfile you can copy things from an image in the registry It totally makes sense considering in multi-stage build you reference local layers but I never imaged using it this way For copying executables etc is fantasticJaga santagostino (@kandros5591)Sat, 18 Feb 2023 11:19 GMT

I was today years old when I learned that `dind` is an acronym for "Docker-in-Docker". I had seen it *everywhere* but never knew what it meant. 🤦🏻♀️ A good reminder to write out the acronym FIRST to make sure everyone's on the same page.

Folks around me investigated some of the alternatives and they found that the time spent in setting/keeping those up cost significantly more than a Docker Desktop subscription. People think their time is free (it's not).Lars Rosenquist (@larsrosenquist)Fri, 17 Dec 2021 07:52 GMT
