terrapyst 0.4.1

A Python Wrapper around the Terraform CLI

Terrapyst

Terrapyst is a Python wrapper around the Terraform CLI.

Usage

Quick Start

Terrapyst usage centers around the Workspace object, which can be used to run the typical Terraform commands in that workspace. Just like with the CLI you have to initialize the workspace before you can run plans or applies.

from terrapyst import Workspace

workspace = Workspace(path="./")
workspace.init()

results, plan = workspace.plan()

if !results.successful:
  raise Exception(f"Terraform run failed without output: {results.stdout}")

if plan.deletions > 0:
  raise Exception("Deletions not expected from this plan")

results, apply_log = workspace.apply(plan_path=plan.plan_path, auto_approve=True)

if !results.successful:
  print("Terraform Apply was not successful.")

for resource_name, resource_data in apply_log.resources.items():
  print(f"${resource_name}: ${resource['message']}")

for output_name, output_data in apply_log.outputs.items():
  print(f"{output_name}:\n")
  print(yaml.dumps(output_data))
  print("\n\n\n")

The plan step can be skipped if you are auto approving.

from terrapyst import Workspace

workspace = Workspace(path="./")
workspace.init()
results, apply_log = workspace.apply(auto_approve=True)

Installation

Terrapyst can be installed with pip.

pip install terrapyst

In addition to Terrapyst you should have the Terraform binary installed on your system.
