# Example: Using RCM with Rake (from a project directory).
#
# Run with:
# rake setup -- --dry # dry run, no changes made
# rake setup -- --debug # verbose output
# rake setup # apply configuration
#
# This example assumes rcm is available via bundler (see Gemfile),
# or you can swap the require for: require_relative '../../lib/dsl'
require 'rcm'
desc 'Apply system configuration'
task :setup do
configure do
# Only run on host named 'earth'
given { hostname is :earth }
# Create a WireGuard config from an inline ERB template.
# The 'manage directory' directive creates /tmp/example/wg/ if it is missing.
