Initializing the Terraform State S3 Backend
Follow these steps to configure and initialize the Terraform state backend using Semaphore, ensuring proper setup of the infrastructure components and state management.
Steps | Actions |
---|---|
Configure Terraform state | task workflow init/tfstate -f baseline |
Setting up the Terraform State Backend
This is where we configure and run Semaphore. Semaphore is a workflow automation tool that we will use to call Terraform which
will provision all the accounts and resources you need to create and manage infrastructure. The Semaphore configuration can
be found in the task.yaml
.
If you're unfamiliar with task, you can read more about it here.
If you look at components/terraform/
, you'll see a bunch of directories. These contain Terraform "root modules" that are provisioned with Semaphore. At first they'll only have their vendor files, such as components/terraform/tfstate-backend/component.yaml
.
1 Vendor the Terraform State Backend component
Vendor the Terraform State Backend component by running the following command. The steps here require the tfstate-backend
and account-map
components.
- Commands
- Taskfile Workflow
vendor
workflow in the examples/snippets/stacks/workflows/baseline.yaml
file:- No commands found
task workflow vendor -f baseline
2 Initialize the Terraform State Backend
Initialize the Terraform State Backend by running the following command:
- Commands
- Taskfile Workflow
init/tfstate
workflow in the examples/snippets/stacks/workflows/baseline.yaml
file:- No commands found
task workflow init/tfstate -f baseline
3 Migrate all workspaces to S3
When prompted, type yes
to migrate all workspaces to S3.

Do you want to migrate all workspaces to "s3"?
The IAM User for super-admin-user will be granted access to Terraform State by principal ARN. This ARN is passed to the
tfstate-backend
stack catalog under allowed_principal_arns
. Verify that this ARN is correct now. You may need to
update the root account ID.
