Snowflake Storage Integration Terraform Module

We help companies turn their data into assets

---

Terraform module for Snowflake storage integration management.

• Creates Snowflake storage integration
• Can create custom Snowflake roles with role-to-role, role-to-user assignments
• Can create a set of default roles to simplify access management:
  • READONLY - granted USAGE privilege

Breaking changes in v3.x of the module

Due to replacement of nulllabel (context.tf) with context provider, some breaking changes were introduced in v3.0.0 version of this module.

List od code and variable (API) changes:

• Removed context.tf file (a single-file module with additonal variables), which implied a removal of all its variables (except name):
  • descriptor_formats
  • label_value_case
  • label_key_case
  • id_length_limit
  • regex_replace_chars
  • label_order
  • additional_tag_map
  • tags
  • labels_as_tags
  • attributes
  • delimiter
  • stage
  • environment
  • tenant
  • namespace
  • enabled
  • context
• Changed support for enabled flag - that might cause some backward compatibility issues with terraform state (please take into account that proper move clauses were added to minimize the impact), but proceed with caution
• Additional context provider configuration
• New variables were added, to allow naming configuration via context provider:
  • context_templates
  • name_schema

USAGE

data "azurerm_client_config" "current" {}

module "snowflake_storage_integration" {
  source = "getindata/storage-integration/snowflake"
  # version  = "x.x.x"

  name = "my_integration"

  type                      = "EXTERNAL_STAGE"
  storage_provider          = "AZURE"
  storage_allowed_locations = ["azure://mystorageaccount.blob.core.windows.net/raw/"]
  azure_tenant_id           = data.azurerm_client_config.current.tenant_id
  
  create_default_roles = true
}

storage_allowed_locations	Explicitly limits external stages that use the integration to reference one or more storage locations	list(string)	n/a	yes
storage_aws_object_acl	Value of "bucket-owner-full-control" enables support for AWS access control lists (ACLs) to grant the bucket owner full control	string	null	no
storage_aws_role_arn	AWS Role ARN	string	null	no
storage_blocked_locations	Explicitly prohibits external stages that use the integration from referencing one or more storage locations	list(string)	[]	no
storage_provider	Storage provider name. Possible values are: S3, S3GOV, GCS, AZURE	string	n/a	yes
type	Type of the storage integration. Defaults: EXTERNAL_STAGE	string	"EXTERNAL_STAGE"	no
