On: Super small Docker image based on Alpine Linux

well, if you have, say 10 nodes on AWS connecting to the docker hub the speed is definitely an issue, because let's be honest here neither are very fast at all

*edit: also, downloads don't just happen in a data centre. chances are your (or many) office connections just really... well, are not very good. also, think of Australia. please think of Australia (our internet is something of a dire situation)

I'm using slugrunner from flynn [0] for deploying my apps. This way I can share a base image, and each compiled slug is about 40mb for ruby apps and 10mb for golang apps. This is similar to how heroku works.

When I deploy, I generate the slug using slugbuilder, push it to a local storage on the same network, and each docker task is instructed to pull the "latest" slug from the slug storage. Containers start after a code update in a couple of seconds.

Continuous deployment can be easy achieved by copying slug from staging to production, similar to how pull docker image each time is currently done.
