github-actions-terraform-infracost

This project is made in the context of flexyfriday with @SoyTecnopata in order to evaluate Infracost tool with Github Actions.

Once your infracost workflow is configured, when doing PR, you can get a nice comment like below

Also, you can use locally in pre-commit and add infracost hook, with costs checks, and for example with this configuration:

    - id: infracost_breakdown
      args:
        - --args=--path=./terraform
        - --args=--terraform-var-file="terraform.tfvars"
        - --hook-config='.projects[].diff.totalMonthlyCost|tonumber < 2'
        - --hook-config='.currency == "USD"'
      verbose: true # Always show costs

will Fail
