Ruby Usage

require 'cfndsl-pipeline'

opts = CfnDslPipeline::Options.new
opts.validation_bucket=   'my-s3-bucket'
opts.validate_cfn_nag=    true
opts.validate_syntax=     true
opts.dump_deploy_params=  false
opts.estimate_cost=       false
opts.save_syntax_report=  false
opts.save_audit_report=   false

output_dir='cloudformation'
input_file='my-cfndsl-template.rb'
cfndsl_extras = [[:yaml, 'standard_tags.yaml']]

pipeline=CfnDslPipeline::Pipeline.new(output_dir, opts)
pipeline.build(input_file, cfndsl_extras)

Tag standards

These are implemented as a simple YAML file. CFNDSL has been extended to generate the appropriate template inputs for each tag key for you, as well as automatically tagging each and every resource that supports tags. All DSL properties of the parameters are supported, in addition to a logical name to use for the parameter key.
