Overview

tfmigrator is a CLI tool to migrate Terraform configuration and State into multiple states. tfmigrator configures rules to classify resources and migrate resources to other states via terraform state mv and hcledit.

Requirement

• Terraform CLI
• hcledit

Download a binary from the release page.

How to use

$ vi tfmigrator.yaml
$ cat *.tf | tfmigrator run [-skip-state]

Configuration file

CONFIGURATION.md

example of tfmigrator.yaml

items:
- rule: |
    "name" not in Values
  exclude: true
- rule: |
    Values.name contains "foo"
  state_out: foo/terraform.tfstate
  resource_name: "{{.Values.name}}"
  tf_path: foo/resource.tf
- rule: |
    Values.name contains "bar"
  state_out: bar/terraform.tfstate
  resource_name: "{{.Values.name}}"
  tf_path: bar/resource.tf

Restriction

tfmigrator migrates Terraform configuration with hcledit and doesn't support to expand the expression. For example, if Terraform configuration refers local values, the migrated configuration may be broken.
