This is a simple HOT example to demonstrate and test the use of a
|
|
SoftwareComponent resource in a Heat stack. The sample will just write some
|
|
text to a file and update an output attribute of the corresponding
|
|
SoftwareDeployment resource so it can be verified which action of the
|
|
SoftwareComponent (and corresponding script) got last run.
