March was busy as we added major new features and had Y Combinator's demo day, where Hassan (our CEO) delivered an awesome 60 second pitch on a Zoom call with hundreds of investors!
A highly requested feature was the ability to see the difference in cost between the current state and the planned state of Terraform projects in the CLI (we already have this feature in CI/CD integrations). Check it out by running
infracost diff --help. We have also updated the CI output to make it easier to read.
Usage-based resources, such as AWS Lambda or Google Cloud Storage, require estimated usage data so Infracost can show costs in the output. You can define these in a YAML file, called a usage file, and use that to get cost estimates for such resources.
Previously you had to create this file manually. You can now use the
--sync-usage-file option to generate a new usage file or update an existing one from your Terraform project. This option is a safe sync: it adds any missing resources (with zeros for the usage estimates), it does not overwrite any lines that you have changed in the YAML, and it deletes any resources that are not used in the Terraform project.
> infracost breakdown --sync-usage-file --usage-file infracost-usage.yml --path /code
> cat infracost-usage.yml
monthly_requests: 0 # Monthly requests to the Lambda function.
request_duration_ms: 0 # Avg duration of each request in milliseconds.
We like it when things are made easy:
Inputs: a new
pathflag has been introduced to replace the various methods of running Infracost. You can now simply point Infracost to the path of a Terraform directory, plan binary file, or plan JSON file and it'll just work. This lays some of the groundwork for supporting other IaC tools in the future.
Outputs: the dashes (-) in the output have been replaced with price descriptions such as
Cost depends on usage: $0.20 per 1M requestsso you can understand the pricing structure of usage-based resources such as AWS Lambda or Google Cloud Storage.
- Config file: the config file has been updated to support infra-as-code repos that have multiple workspaces and projects. This enables you to combine projects into the same breakdown or diff output. So if a Terraform module or variable is used across workspaces/projects, you can quickly see the cost impact of changing it.
We've updated the CI/CD integrations to add a new
post_condition option so you can decide when you'd like cost comments to be shown in pull requests. Options include: always leave a cost comment, only comment when there is a change to the cost, or only comment when a percentage threshold has been reached (e.g. more than 5% increase or decrease in costs).
We are working on adding Microsoft Azure to Infracost. This has two steps: the first is to add the prices to the Cloud Pricing API, then to add the resources to the CLI. We completed adding around 300,000 prices from Microsoft Azure to the Cloud Pricing API (step one), and now we're looking for volunteers to add resources to the CLI (step two) before the initial release. Please email email@example.com if you are an Azure user and would like to contribute (basic golang knowledge is required).
We also added support for the following cloud resources:
- AWS: Elastic File System (EFS), EBS GP3 volumes, DX Connection, Route53 Health checks, RDS Serverless
- Google: Memorystore Redis, Cloud Monitoring and Logging, Compute Images and Snapshots
Thanks for being part of the community! We are always looking forward to your feedback.
