SummaryA tight feedback loop is important when developing code. Terraform is no different. At times, it would be helpful to have a quick way to test function calls. In this post, I introduce a tool I have created that does just that.
At times when I am developing Terraform it would be helpful to be able to quickly test a function call. Typically, when writing regular expressions or building subnets. In these situations it can be painful to make a change and do a terraform plan to see what the changes would be.
For this reason, I created a docker image that will take the first argument passed and evaluate it with Terraform.
> terraform-eval "cidrsubnet(\"172.16.0.0/12\", 4, 2)" 172.18.0.0/16
Instructions and more examples on how to use the tool are available in the Github repo.
