# syntax = docker/dockerfile:experimental

# Dockerfile used to build a deployable image for a Rails application.
# Adjust as required.
#
# Common adjustments you may need to make over time:
#  * Modify version numbers for Ruby, Bundler, and other products.
#  * Add library packages needed at build time for your gems, node modules.
#  * Add deployment packages needed by your application
#  * Add (often fake) secrets needed to compile your assets
