Terraform State Management with DE-CIX Resources

Terraform tracks all managed resources in a state file.

How Terraform State Works

  • Terraform stores resource IDs and attributes
  • Removing resources deletes them on apply
  • Some changes recreate resources 

terraform {
  backend "s3" {
    bucket = "my-terraform-state"
    key    = "de-cix/cloud-router/terraform.tfstate"
    region = "eu-central-1"
  }
}

Resource Deletion Order

  • Delete Network Service Configs (NSCs) first
  • Then delete the Cloud ROUTER (VRF)
  • Cloud VC services must be detached before deletion
  • Prefix lists and policies can be deleted independently

Prevent Accidental Deletion

resource "ixapi_de_cix_cloud_router" "main" {
  lifecycle {
    prevent_destroy = true
  }
}

Best Practices

  • Always review terraform plan before apply
  • Use remote state
  • Avoid manual changes
