Provide a CircleCI base alpine image with all standard tools installed
We're using any of the fat-images (e.g. circleci/php:7.1-node-browsers) to run small jobs like building a docker container. These images take a long time to start up (download, extract, start).
Provide an alpine base images with all the tools installed as described in the CircleCI documentation (e.g. docker). This will
Reduce start time
Reduce strain on CircleCI infrastructure
@Han Hui: You can use your any image that exists on Docker Hub too, that's how I use custom alpine-based images for my builds.

It'd be best if we don't have to use any pre-built images provided by CircleCI. (And it removes that burden from the CircleCI team as well.) We'd very much like to use our own images. If it's possible, there needs to be better documentation on how it could be achieved.
Thanks for your suggestion Encrico. Right now we provide this reasonably small Debian-based image (~270MB) with just the basic tools: https://hub.docker.com/r/circleci/buildpack-deps/tags/. Would the set of tools in that image be sufficient for your use case? Thanks!
