How ima.ge.cx works

How ima.ge.cx works

ima.ge.cx is Aidan Steele's web tool for browsing the contents of Docker images hosted on Docker Hub. The architecture is really interesting: it's a set of AWS Lambda functions, written in Go, that fetch metadata about the images using Step Functions and then cache it in DynamoDB and S3. It uses S3 Select to serve directory listings from newline-delimited JSON in S3 without retrieving the whole file.
