[SOLVED] terragrunt apply from root folder

terragrunt apply from root folder

I need to work with terraform and terragrunt. There would be like 15 20 resources/services of AWS I need to deploy using IAC, while working on terragrunt what I found is if one of the layer needs to be applied, I need to go into that particular directory and run terragrunt plan/apply.

I was thinking if there is possible way to do the terragrunt apply just by sitting on the root folder. My folder structure now:

Root folder: terraform/
/layers/
          /iam-policies/main.tf
          /sagemaker/main.tf

Then for terragrunt similarly as layers(tf) environments(terragrunt/hcl) is also in the terraform folder:

/environments/
        /iam-policies/terragrunt.hcl
       /sagemaker/terragrunt.hcl

Is there a way to apply iam-policies or sagemaker layer from the root folder i.e terraform?

Solution

You can use the terragrunt-include-dir flag for this.

terragrunt plan-all --terragrunt-include-dir "iam-policies" --terragrund-include-dir "sagemaker"

There are other CLI options that can be combined to achieve even finer selections in your directories.
