We have recently released a new Terragrunt native platform in Spacelift and it is currently in beta. You can find documentation on this here
Whether a Terraform stack is using Terragrunt or not is controlled by the presence of
terragrunt label on the stack:
If present, all workloads will use
terragrunt instead of
terraform as the main command. Since the Terragrunt API is a superset of Terraform's, this is completely transparent to the end user.
During the Initialization phase we're showing you the exact binary that will process your job, along with its location:
Versioning with Terragrunt»
When working with Terragrunt, you will still specify the Terraform version to be used to process your job. We don't do it for Terragrunt, which is way more relaxed in terms of how it interacts with Terraform versions, especially since we're only using a very stable subset of its API.
On our runner image, we install a version of Terragrunt that will work with the latest version of Terraform that we support. If you need a specific version of Terragrunt, feel free to create a custom runner image and install the Terragrunt version of your choosing.
Scope of support»
We're currently using Terragrunt the same way we're using Terraform, running
apply commands. This means we're not supporting executing Terraform commands on multiple modules at once (
run-all). This functionality was designed to operate in a very different mode and environment, and is strictly outside our scope.
We also support authentication with Spacelift modules by automatically filling the
TG_TF_REGISTRY_TOKEN environment variable for each run. Terragrunt uses this variable to authenticate with private module registries.
Similar to Terraform, Terragrunt provides an advanced logging mode, and as of the writing of this documentation, there are currently two ways it can be enabled:
--terragrunt-log-level debugCLI flag (You'll need to set this flag using the
TF_CLI_ARGSenvironment variable. For example,
TERRAGRUNT_LOG_LEVELenvironment variable. Logging levels supported:
Please refer to the Setting Environment Variables section within our Terraform Debugging Guide for more information on how to set these variables on your Spacelift Stack(s).
