 <br />Since I used Infracost in this repository, I stored the `INFRACOST_API_KEY` as a repository secret. It is referenced in the [`terraform.yml`](https://github.com/kunduso/amazon-elasticache-redis-tf/blob/eb148db2b9ff37cff9f1fb469d0c14b6479bd57a/.github/workflows/terraform.yml#L52) GitHub actions workflow file.
 <br />As part of the Infracost integration, I also created a `INFRACOST_API_KEY` and stored that as a GitHub Actions secret. I also managed the cost estimate process using a GitHub Actions variable `INFRACOST_SCAN_TYPE` where the value is either `hcl_code` or `tf_plan`, depending on the type of scan desired.
