KodeKloud Notes

Welcome to this lesson on OpenTofu state management. In this guide, we’ll cover where the state file lives, how OpenTofu tracks resources, default filenames, inspecting state, and working with both local and AWS resources.

Default State File Location

After you provision resources with OpenTofu, the state file is created in your current working directory by default.

Disabling State

OpenTofu always relies on a state file to track existing resources. There is no option to disable this behavior.

Warning

OpenTofu always maintains a local state file (terraform.tfstate). You cannot disable state management.

The image shows a Visual Studio Code editor with a welcome message for KodeKloud OpenTofu Lab on the right, and a task question about disabling state on the left.

State File Format

Open the terraform.tfstate file and you’ll see it’s formatted in JSON.

Note

The JSON format makes it easy to parse the state file with tools like jq or programmatic scripts.

Commands and State Refresh

Some OpenTofu commands automatically refresh the state to match real-world resources:

Command	Refreshes State?	Description
`opentofu plan`	Yes	Generates and shows an execution plan
`opentofu apply`	Yes	Applies changes and refreshes state
`opentofu init`	No	Initializes the working directory

Default State File Name

By default, the state file created is:

terraform.tfstate

Working with State in a Configuration

Navigate into your configuration directory:

cd /root/OpenTofu-project/project

You’ve already run opentofu init, so the .terraform folder exists—but no terraform.tfstate file yet, since opentofu apply hasn’t been executed.

1. Showing the State

opentofu show

No output appears because no state file exists yet.

2. Applying the Configuration

Run:

opentofu apply

When prompted, type yes. Sample output:

local_file.zoom: Creating...
local_file.ridder: Creating...
local_file.reverse-flash: Creating...
local_file.speed_force: Creating...
local_file.zoom: Creation complete after 0s [id=49a99e298eb6c5658742c255584f940948]
local_file.ridder: Creation complete after 0s [id=e9cbflbe0ee8cca695b7925def345088e16c7]
Apply complete! Resources: 4 added, 0 changed, 0 destroyed.

3. Inspecting the New State

Now re-run:

opentofu show

Search for the resource local_file.speed_force. In HCL form, it appears as:

# local_file.speed_force:
resource "local_file" "speed_force" {
  content                  = "speed-force"
  content_base64sha256     = "H5f8B6uJ7VQ7K0KVE0HT1hjs5aRlnpODNyZEt1L"
  content_base64sha512     = "C0fhaaC0aw1TigerQ8gYu6fu8n6onK91L1jctPU++M+HrPjS/LSKJHTV0v8QX8BQ78sR"
  filename                 = "ebeb8b595c8eb4e8e1acf24416a742fab2981"
  directory_permission     = "0777"
  file_permission          = "0777"
}

Here, the suffix fab2981 in the filename reflects the resource ID.

Add an EC2 instance and an S3 bucket to your configuration:

resource "aws_instance" "dev-server" {
  instance_type = "t2.micro"
  ami           = "ami-02cf456777cd"
}

resource "aws_s3_bucket" "flashpoint" {
  bucket = "project-flashpoint-paradox"
}

After running opentofu apply, inspect the JSON state directly or with:

opentofu show

A snippet for the EC2 instance in terraform.tfstate:

{
  "mode": "managed",
  "type": "aws_instance",
  "name": "dev-server",
  "instances": [
    {
      "attributes": {
        "ami": "ami-02cf4456777cd",
        "arn": "arn:aws:ec2:us-east-1:instance/i-5dbf6192afa91dd3",
        "associate_public_ip_address": true,
        "availability_zone": "us-east-1a",
        "private_ip": "10.40.132.251",
        "public_ip": "54.214.161.80"
      }
    }
  ]
}

Search for "private_ip" to locate the instance’s private IP:

"private_ip": "10.40.132.251"
