Migration TFC/E to Scalr

This module helps Terraform Cloud/Enterprise users migrate their workspaces to Scalr remote backend.

Prior to the migration, please do the following:

  • Obtain a TFC/E personal or team access token. This can be done in two ways: manually or via terraform login.
  • Obtain a Scalr access token. The easiest way it to obtain via the terraform login account-name.scalr.io command.
  • Register a VCS provider in Scalr. Note that the registered provider must have the access to all repositories connected to the TFC/E workspaces. After the provider is created, copy the VCS provider id.
  • Obtain the Scalr account identifier. It can be found on the account dashboard.

What Terraform Cloud/Enterprise objects will be migrated:

  • Organizations - Will be migrated into Scalr environments
  • Workspaces - Will be migrated into Scalr workspaces. Only VCS based workspaces will be migrated. CLI-driven workspaces have to be migrated manually.
  • Workspace variables - Terraform and non-sensitive environment variables will be created as Terraform and shell variables at the workspace level.
  • State files - The current state file of a workspace will be migrated to Scalr state storage.

Usage

  • Assuming you will use the Terraform CLI, create a main.tf locally.
  • Then copy and paste the following source code and fill in the required inputs:
module "migrator" {
  source = "github.com/Scalr/terraform-scalr-migrate-tfc"
  
  # required inputs
  tf_token = "<tfc-token>"
  tf_organization = "<tf-organization-name>"

  scalr_account_id = "<scalr-account-id>"
  scalr_hostname = "<scalr-hostname>"
  scalr_token = "<scalr-token>"
  scalr_vcs_provider_id = "<scalr-vcs-id>"
  
  # optional inputs
  # by default, it takes the TFC/E organization name to name a Scalr environment after. 
  # But users could set a custom environment name
  scalr_environment = "<scalr-environment-ID>" 
  # by default, the tool migrates all Terraform Cloud/Enterprise workspaces, but the user can control 
  # which workspaces you want to migrate into Scalr.
  workspaces = ["*"]
  # by default, the tool locks Terraform Cloud/Enterprise workspaces in order to keep a single source of state
  lock_tf_workspace = true
}
  • Run terraform init and then terraform apply
  • After the migration is done you still have to configure the provider configurations or sensitive shell variables order to authorize your pipelines.
  • After the secrets configuration is done - trigger the run to double-check workspaces work as expected and generate no changes.
