Heat CloudFormation Tools
There are several bootstrap methods for cloudformations: 1. Create image with application ready to go 2. Use cloud-init to run a startup script passed as userdata to the nova server create 3. Use the CloudFormation instance helper scripts
This package contains files required for choice #3.
- cfn-init - Reads the AWS::CloudFormation::Init for the instance resource,
-
installs packages, and starts services
- cfn-signal - Waits for an application to be ready before continuing, ie:
-
supporting the WaitCondition feature
cfn-hup - Handle updates from the UpdateStack CloudFormation API call
