A Terragrunt rapid development tool to simplify overriding the source parameter in a terraform.tfvars file.
Introduction
terragrunt-source is a simple script that parses the source line from the terraform.tfvars file in the current working directory producing a path to a local source tree that can be used by terragrunt during development. The path to the local source tree is looked up in the environment variable TERRAGRUNT_DEFAULT_MODULES_REPO.
This is best illustrated be an example. If you are in a directory that contains a terraform.tfvars file with the following content:
terragrunt = { include { path = "${find_in_parent_folders()}" } terraform { source = "git::git@github.com:org/repo.git//lambda?ref=v0.6.2" } }
And if TERRAGRUNT_DEFAULT_MODULES_REPO is set to /usr/src/modules then then we expect the following output:
$ terragrunt-source /usr/src/modules//lambda
Then we can use terragrunt like so:
$ terragrunt plan --terragrunt-source `terragrunt-source`
Another way this can be run is as follows:
$ TERRAGRUNT_SOURCE=`terragrunt-source` terragrunt plan
Quick start
Install terragrunt-source:
$ pip install terragrunt-source
Append the following to your ~/.bashrc:
export TERRAGRUNT_DEFAULT_MODULES_REPO=/path/to/your/checked/out/code terragrunt-source() { TERRAGRUNT_SOURCE=$($(which terragrunt-source)) terragrunt $@ }
Reload your ~/.bashrc:
$ source ~/.bashrc
Change to a Terragrunt configuration directory:
$ terragrunt-source plan
