TerraformStateBackend 3 min read

Managing Terraform state in team. Remote backend, locking, state operations.

Remote Backend¶

terraform {
  backend "s3" {
    bucket         = "my-terraform-state"
    key            = "prod/terraform.tfstate"
    region         = "eu-central-1"
    dynamodb_table = "terraform-locks"
    encrypt        = true
  }
}

State Operations¶

terraform state list              # List resources
terraform state show aws_instance.web  # Detail
terraform state mv old.name new.name   # Rename
terraform state rm resource.name       # Remove from state
terraform import aws_instance.web i-1234  # Import existing

Summary¶

Remote state + locking is a must in teams. Never commit .tfstate to git (contains secrets).
