Parse Terraform plan in json format and give feedback.

terraplanfeed

This tool parses Terraform plan files in JSON format and gives feedback about the changes.

Description

This tool aims to parse Terraform plan files (in JSON format) and gives feedback to several types of outputs.

Outputs can be:

• stdout: stdout
• azuredevops: Azure DevOps pull request comment
• github: Github pull request comment (not yet implemented)

To create the Terraform plan file:

terraform init
terraform plan -out=plan.out
terraform show -no-color -json plan.out > plan.json

Usage

To write to stdout you just need to pass a JSON file:

❯ terraplanfeed ../tfplan/example.json

To use this on Azure DevOps you need the following environment variables:

• SYSTEM_TEAMFOUNDATIONSERVERURI
• SYSTEM_TEAMPROJECT
• BUILD_REPOSITORY_ID
• SYSTEM_PULLREQUEST_PULLREQUESTID
• SYSTEM_ACCESSTOKEN

these environment variables are present when you run Azure DevOps pipelines.

Note: The SYSTEM_PULLREQUEST_PULLREQUESTID is only present when you run pipeline in a pull request.
