Cfn Status

Helper library provides status of CloudFormation stack.

Usage

Add this line to your gem's gemspec:

  gem.add_development_dependency "cfn-status"

Require it to your library:

require "cfn_status"

Use like so:

status = CfnStatus.new(stack_name)
status.run # prints out stack events

The status.run will:

• print out the most recent stack events and return right away if the stack is in a completed state.
• print out the most recent stack events and poll for more events until the stack in a completed state.

To find out whether the most recent completed state of the stack was a success or a fail, you can use status.success?.

status.success?

If you need to just wait for the stack to complete, you can also use status.wait.

status.wait
status.success?
