Building and compiling code can take a huge hit on our time and resources. If you have dockerized your application, you may have noticed how much of a time-saver Docker cache is. Lengthy build commands can be cached and not have to be run at all! This works great when you’re building on a single host; however, once you start to scale up your Docker hosts, you start to lose that caching goodness.

Our requirements for preserving a single-tenant infrastructure for our customers meant we needed a horizontally scalable solution. This post will go through some methods we considered to distribute Docker cache across multiple Docker hosts.
