Overview

Builds and smoke-checks the base image. Compiles the rubies from source, so the first build is 15-30 minutes and every later one is cached.

Constant Summary collapse

NEED_GB =

Compiling two rubies from source measured about 8 GB. Less than an app image, but it is the longest build in the tool, so losing it to a full disk costs the most.
