Show the cost of each change in review
Show the monthly cost change of every infrastructure pull request in the review. Ask the budget owner to approve any change above a set amount.
How to do it
Use a tool such as Infracost, which reads the plan and prices it. Post the difference as a comment on the pull request. Set the approval limit as a share of the monthly budget, such as 10 percent.
Example
infracost breakdown --path infra/production --format json --out-file base.json # on the main branch
infracost diff --path infra/production --compare-to base.json # on the pull requestHow to check
A pull request that adds a large database shows its monthly price in a comment. It cannot merge without the budget owner's approval.
