Terraform Backend

1. Backend Config:

• Backends determine where Terraform State is stored
  • must run terraform init to restart
  • terraform init -migrate-state to migrate where state is stored
• Stored as a backend block within terraform block
• Responsible for State locking
  • not all backends support state locking
• Available backends:
  • Cant load additional backends as plugins
• Using backend block:
  • This tells Terraform where to store as backend
  • A config can only have 1 backend block
  • cant refer to named value
  • when using Terraform Cloud, it doesnt need to have backend block

2. Available backends:

• Local

  ```hcl
    terraform {
      backend "local" {
        path = "terraform/state/terraform.tfstate"
      }
    }
    ```
  

• Remote

  ```hcl
      terraform {
    	  backend "remote" {
    		organization = "example_corp"
    	
    		workspaces {
    		  name = "my-app-prod"
    		}
    	  }
    	}
    ```
