  Terraform can store the state remotely, making it easier to version and work with in a team.
---

# mas

Stores the state as a given key in a given bucket on [Microsoft Azure Storage](https://azure.microsoft.com/en-us/documentation/articles/storage-introduction/).

-> **Note:** Passing credentials directly via config options will
make them included in cleartext inside the persisted state.
Use of environment variables or config file is recommended.

## Example Usage

```
terraform remote config \
  -backend=mas \
  -backend-config="storage_account_name=terraform123abc" \
  -backend-config="container_name=terraform-state" \
  -backend-config="key=prod.terraform.tfstate"
```

## Example Referencing

```hcl
# setup remote state data source
data "terraform_remote_state" "foo" {
  backend = "mas"
  config {
    storage_account_name = "terraform123abc"
    container_name       = "terraform-state"
    key                  = "prod.terraform.tfstate"
  }
}
```
