terraform-state-mover's Introduction

Terraform State Mover

Helps refactoring terraform code by offering an interactive prompt for the terraform state mv command.

Installation

Using homebrew:

brew install mbode/tap/terraform-state-mover

Alternatively, get a pre-built binary from the latest release or build it yourself using

go get github.com/mbode/terraform-state-mover

Usage

terraform-state-mover # inside a Terraform root directory

Extra arguments after a -- are passed to the terraform plan call. This makes the following possible:

terraform-state-mover -- -var key=value  # set variables
terraform-state-mover -- -var-file=variables.tfvars  # use variable files
terraform-state-mover -- -refresh=false  # skip state refresh
terraform-state-mover -- -parallelism=50  # speed up plan by using more concurrent operations

Hint: If terraform-state-mover is used with the Google Cloud Platform provider and remote state, it is recommended to use --delay=2s, otherwise API rate limits error might occur.

terraform-state-mover's Issues

Feature request: Order suggestions based on editing distance

If many resources needed to be moved (e.g. because extracted to a new module) with similar resource types, it would be helpful if the list of suggested target resources are ordered by editing distance between the source/target resource paths such that the top-most/preselected target resource is more probably the correct one.

Rate-limiting terraform state mv calls

For example, with the google terraform provider and remote state, terraform state mv could only be called approximately every 2 seconds, otherwise the state cannot be locked anymore due to rate limits by Google APIs.

If there are more than only few renamings, terraform-state-mover could fail because of this. It would be nice if there is either a default rate limit or a flag which allows to delay the terraform calls.

Terragrunt Support

Hi, I was just wondering if at all, there was a plan or an existing way to read input variables from a gruntwork terragrunt file instead of a tfvars file?

root@c6cacc87b3af:/workdir/environments/poc# terraform-state-mover -- -var-file=terragrunt.hcl

Error: Unexpected "include" block

  on terragrunt.hcl line 1:
   1: include {

Blocks are not allowed here.

exit status 1

Propagate -parallelism=50 tf plan CLI argument to planner.go

To achieve faster plan, I had to modify source code to make 22nd line of planner.go file like the following:

if err := terraformExec(cfg, true, args, "plan", "-out="+tfPlanName, "-parallelism=60"); err != nil {

Would be nice to have this as a built-in feature

Ability to move resources between state files

Does this support the ability to move select resources from one state file to another state file?
