Module: HotCell::Install

Defined in:
lib/hot_cell/install.rb

Overview

Writes the hotcell/ directory into an application: a complete Dockerfile to customize, the cell's Gemfile, and an operations/ directory the cell loads at boot. Everything installs inline rather than deriving from a published base image, so the whole cell is the application's to read and change.

A file that already exists is left exactly as it is, so running this again after customizing is safe.
