Back in February, we started an ambitious journey: remove our dependency on the Terraform CLI by parsing code directly! We’re excited to announce Infracost v0.10, which completes that journey 🎉
Infracost is now much faster, simpler to add to CI/CD, and does not need cloud creds since a Terraform plan is not required.
Checkout the migration guide to upgrade. The experimental
--terraform-parse-hcl flag has been removed and going forward, Infracost can be run in two ways via
- Parsing HCL code (directory): the default and recommended option as it has the following 5 benefits.
# Terraform variables can be set using --terraform-var-file
# or --terraform-var
infracost breakdown --path /code
- Parsing plan JSON file: this will continue to work as before.
terraform plan -out tfplan.binary
terraform show -json tfplan.binary > plan.json
infracost breakdown --path plan.json
1. Faster CLI
Removing the need for
terraform init and
terraform plan means a super-fast CLI: Infracost used to take around 50 seconds to run on our internal Terraform mono-repo, that’s now reduced to 2 seconds 🚀
2. No cloud creds needed
Removing our dependency on the Terraform CLI means you no longer need to set cloud credentials or Terraform secrets, which simplifies CI/CD integrations too.
3. Cost of TF modules
Not needing cloud creds/secrets or a Terraform plan means you can now generate cost estimates from Terraform modules. It also enables cost estimates to be put in Infra-as-Code repo readmes and Visual Studio!
infracost diff work without a plan, we introduced a new
--compare-to flag so git-based cost diffs can be produced:
git checkout main
infracost breakdown --path /code --format json \
git checkout my-branch
infracost diff --path /code --compare-to infracost-base.json
4. Compare Infracost runs
infracost diff command can now also be used to compare Infracost runs to see what’s changed between historic runs:
infracost diff --path infracost-today.json \
5. Detect multi-project repos
We added support for the following cloud resources and identified many more free resources:
- AWS: Support for reservation in
