Designed to analyze terraform template files and return a cost estimate of running the infrastructure, assuming AWS is the target cloud. Perhaps other clouds can be supported going forward?
NOTE: This only calculates the cost of EC2 and RDS resources right now. To add support for more resources, open a PR or leave a comment. I'm always looking for feedback.
This is very much in a prototype state right now. Any advice or assistance is appreciated.
This relies on terraform plan files generated using terraform plan -out=<filename>.
It is recommended that you plan against an empty state so that all of your resources
are present in the plan file.
If you are using remote state, you will need to disable this. I accomplish this by renaming the
file that defines my remote state, appending the extension .off. Then, I have to run
terraform init again to initialize a blank local state. Then I can generate a plan that contains
all my resources using the following command terraform plan -out=<filename> -refresh=false.
| Variable Name | Description |
|---|---|
| AWS_REGION | The Region for which you want to create a price estimation (e.g. us-east-1) |
| TERRAFORM_PLANFILE | Where cashier should find your terraform plan output. |
| RUNNING_HOURS | (Optional) The number of running hours normally used in a month for your resources, on average. Defaults to 730 assuming 24/7 operation. |
| GRAPHQL_API_URL | (Optional) Change the API URL that cashier uses. Defaults to live API Gateway URL. |
| PRINT_VERSION | (Optional) If true will print current version of cashier and exit |
Simply download the latest release from the releases page here: https://github.com/Bjorn248/terraform_cashier/releases Make sure that the binary is set executable Set your environment variables appropriately
export TERRAFORM_PLANFILE="./terraform.plan"
export AWS_REGION="us-west-1"
And then run the cashier binary
If you wish to see the current version of cashier, use the following environment variable
PRINT_VERSION=true
