Overview

Stack Summaries

Stack summaries contain information about CloudFormation stacks. You can filter the stacks you want summary information for by one or more statuses. You can even get information about deleted stacks for up to 90 days.

Enumerating Stack Summaries

You can enumerate all available summaries using enumerable methods. Yielded summaries are simple hashes.

cfm = AWS::CloudFormation.new
cfm.stack_summaries.each do |summary|
  puts summary.to_yaml
end

Filtering Stack Summaries

You can optionally provide one or more stack stasus values to filter the results by. Only stacks with the given status(es) will be enumerated.

cfm.stack_summaries.with_status(:create_failed).each do |summary|
  # ...
end

# enumerate stacks with various delete statuses
statuses = %w(delete_in_progress delete_failed delete_complete)
cf.stack_summaries.with_status(statuses).each do |summary|
  # ...
end

You can provide multiple statuses:

statuses = [:create_failed, :rollback_failed]
cfm.stack_summaries.with_status(statuses).each do |summary|
