Reusable bits of infrastructure for testing/dev work, deployed/managed with Terragrunt.
Update terragrunt.hcl files to fit your needs. The files are hierarchical,
so /terragrunt.hcl contains common settings while
/us-east-1/vpc/terragrunt.hcl contains settings that only apply to
a VPC in us-east-1.
Then with Terragrunt installed:
# See what would happen to deploy a single VPC
terragrunt plan --terragrunt-working-dir us-east-1/vpc
# which is equivalent to:
cd us-east-1/vpc && terragrunt plan
# See what would happen if we deploy everything
terragrunt run-all plan
# Substitute "apply" for "plan" to actually make changes
