Terraform module for Snowflake Resource Monitor management

  • Creates Snowflake Resource Monitor
  • Can create custom Snowflake Roles with role-to-role, role-to-user assignments
  • Can create a set of default, functional roles to simplify access management:
    • ADMIN - full access
    • MODIFY - abillity to modify resource monitor
    • MONITOR - abillity to monitor resource monitor

USAGE

module "resource_monitors" {
  source = "getindata/resource-monitor/snowflake"

  name = "example_resource_monitor"

  credit_quota = 50

  notify_triggers            = [50, 80, 90]
  suspend_triggers           = [100]
  suspend_immediate_triggers = [110]

  set_for_account = true
}

EXAMPLES

Breaking changes in v4.x of the module

Due to replacement of nulllabel (context.tf) with context provider, some breaking changes were introduced in v4.0.0 version of this module.

List of code and variable (API) changes:

  • Removed context.tf file (a single-file module with additional 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
  • Remove support 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

Additionally, due to breaking changes introduced in snowflake terraform provider v0.96.0 (snowflake_resource_monitor resource):

  • Removal of set_for_account variable / flag (will be settable on account resource)
  • Removal of warehouses variable (will be settable on warehouse resource)

Breaking changes in v5.x of the module

  • Due to rename of Snowflake terraform provider source, all versions.tf files were updated accordingly.

    Please keep in mind to mirror this change in your own repos also.

    For more information about provider rename, refer to Snowflake documentation.

Inputs

Name Description Type Default Required
context_templates Map of context templates used for naming conventions - this variable supersedes naming_scheme.properties and naming_scheme.delimiter configuration map(string) {} no
create_default_roles Whether the default roles should be created bool false no
credit_quota The number of credits allocated monthly to the resource monitor. number null no
end_timestamp The date and time when the resource monitor suspends the assigned warehouses. string null no
frequency The frequency interval at which the credit usage resets to 0. If you set a frequency for a resource monitor, you must also set START_TIMESTAMP. string null no
name Name of the resource string n/a yes
name_scheme Naming scheme configuration for the resource. This configuration is used to generate names using context provider:
- properties - list of properties to use when creating the name - is superseded by var.context_templates
- delimiter - delimited used to create the name from properties - is superseded by var.context_templates
- context_template_name - name of the context template used to create the name
- replace_chars_regex - regex to use for replacing characters in property-values created by the provider - any characters that match the regex will be removed from the name
- extra_values - map of extra label-value pairs, used to create a name
- uppercase - convert name to uppercase
