I finally got around to automatically publishing new versions of my "unofficial AWS CodeBuild base image" project (and migrating to public ECR instead of Docker Hub).
If you want custom images without the perf penalty, this is probably up your alley.
gallery.ecr.aws/aidansteele/...
gallery.ecr.aws
Amazon ECR Public Gallery is a website that allows anyone to browse and search for public container images, view developer-provided details, and see pull commands
