Infracost is a super cool tool that lets you calculate the cost of your Terraform resources on AWS, GCP, or Microsoft Azure before you even hit deploy. This enables you to see cloud cost estimates for Terraform in pull requests.<\/p>\n\n\n\n\n\n\n\n
Modules<\/strong><\/h2>\n\n\n\n\n- Infracost can even scan modules within your project and pull all the pricing details in seconds.<\/li>\n<\/ul>\n\n\n\n
\n- Public modules are automatically downloaded, but you need to setup access for private modules so Infracost can process them.<\/li>\n<\/ul>\n\n\n\n
Private modules<\/h3>\n\n\n\nS3 modules<\/strong><\/h4>\n\n\n\nIf you store your private modules in an S3 bucket, you need to provide readonly AWS IAM credentials, so the CLI can download them and estimate their costs.<\/p>\n\n\n\n

Installing Infracost and Registering for API key<\/strong><\/h2>\n\n\n\n1. Install Infracost<\/h3>\n\n\n\n
The easiest way is to use our install script, This will install the binary for infracost and will also add the same to path (\/usr\/local\/bin\/infracost). <\/p>\n\n\n\n
curl -fsSL https:\/\/raw.githubusercontent.com\/infracost\/infracost\/master\/scripts\/install.sh | sh<\/code><\/pre>\n\n\n\nCheck that it works correctly<\/p>\n\n\n\n
infracost --version<\/code><\/pre>\n\n\n\n2. Get API Key<\/h3>\n\n\n\n
Register for a free API key, used by the CLI to authenticate\/retrieve prices from our Cloud Pricing API. Run infracost auth login<\/strong> to get a free API key.<\/p>\n\n\n\ninfracost auth login<\/code><\/code><\/pre>\n\n\n\n![\"\"](\"https:\/\/opstree.com\/blog\/\/wp-content\/uploads\/2023\/05\/image-1.png?w=1024\")

\n- After this step, your API key will be stored in credentials.yml file and Infracost will be all set.<\/em><\/li>\n\n\n\n
- To be able to run Infracost locally or in CI you will need to save the API key in an environment variable<\/li>\n<\/ul>\n\n\n\n
export INFRACOST_API_KEY=ico-Something<\/code><\/pre>\n\n\n\n\n- Infracost also has an optional Infracost Cloud<\/a>, which comes with a paid tier and includes features like Jira integration, custom price books, and a dashboard to keep track of costs over time.<\/li>\n<\/ul>\n\n\n\n

<\/figure>\n\n\n\nGenerate a report of all the estimations.<\/h2>\n\n\n\n
You can also save this output in a json\/Html\/table file by running.<\/p>\n\n\n\n

The best part of infracost is that at last, it helps to generate reports. The report is in html form. Let’s generate the report now.<\/p>\n\n\n\n

Infracost helps organizations and individuals estimate and manage the cost of their cloud infrastructure. <\/p>\n\n\n\n
Overall, Infracost is a valuable tool It provides a simple and effective way to estimate and manage costs, identify cost-saving opportunities, and make informed decisions about infrastructure changes.<\/p>\n\n\n\n
