How to parse Terraform Plan Status Code for your Spinnaker Pipeline Logic

Introduction

When using Armory's Terraform Plan stage - you can use SpEL (Pipeline Expression) to retrieve the exitcode.

• 0 = Succeeded with empty diff (no changes)* 1 = Error* 2 = Succeeded with non-empty diff (changes present) ${#stage("Terraform Plan").outputs.status.code} The pipeline expression can be used in a "Check Preconditions" stage in order to assert a particular value for the status code before proceeding or terminating the pipeline. Alternatively, the expression can be used in the "Execution Options" under a "Manual Judgment" stage so you can bypass the Manual Judgement stage when you want to automatically apply a change.
