databricks_storage_credential Resource

-> Public Preview This feature is in Public Preview. Contact your Databricks representative to request access.

To work with external tables, Unity Catalog introduces two new objects to access and work with external cloud storage:

  • databricks_storage_credential represents authentication methods to access cloud storage (e.g. an IAM role for Amazon S3 or a service principal for Azure Storage). Storage credentials are access-controlled to determine which users can use the credential.
  • databricks_external_location are objects that combine a cloud storage path with a Storage Credential that can be used to access the location.

Example Usage

For AWS

resource "databricks_storage_credential" "external" {
  name = aws_iam_role.external_data_access.name
  aws_iam_role {
    role_arn = aws_iam_role.external_data_access.arn
  }
  comment = "Managed by TF"
}

resource "databricks_grants" "external_creds" {
  storage_credential = databricks_storage_credential.external.id
  grant {
    principal  = "Data Engineers"
    privileges = ["CREATE_TABLE"]
  }
}

For Azure

resource "databricks_storage_credential" "external" {
  name = azuread_application.ext_cred.display_name
  azure_service_principal {
    directory_id   = var.tenant_id
    application_id = azuread_application.ext_cred.application_id
    client_secret  = azuread_application_password.ext_cred.value
  }
  comment = "Managed by TF"
}

resource "databricks_grants" "external_creds" {
  storage_credential = databricks_storage_credential.external.id
  grant {
    principal  = "Data Engineers"
    privileges = ["CREATE_TABLE"]
  }
}

Argument Reference

The following arguments are required:

  • name - Name of Storage Credentials, which must be unique within the databricks_metastore. Change forces creation of a new resource.

aws_iam_role optional configuration block for credential details for AWS:

  • role_arn - The Amazon Resource Name (ARN) of the AWS IAM role for S3 data access, of the form arn:aws:iam::1234567890:role/MyRole-AJJHDSKSDF

azure_service_principal optional configuration block for credential details for Azure:

  • directory_id - The directory ID corresponding to the Azure Active Directory (AAD) tenant of the application
  • application_id - The application ID of the application registration within the referenced AAD tenant
  • client_secret - The client secret generated for the above app ID in AAD. This field is redacted on output

Import

This resource can be imported by name:

$ terraform import databricks_storage_credential.this <name>
