+# 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
