Module: managed-grafana

This module is responsible for provisioning an Amazon Managed Grafana workspace.

Introduction​

Amazon Managed Grafana is a fully managed service for Grafana, a popular open-source analytics platform that enables you to query, visualize, and alert on your metrics, logs, and traces.

Deploy this module alongside terraform-aws-managed-prometheus to visual metrics or add a Grafana Loki data source to visualize logs.

Usage​

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

locals {
  enabled = module.this.enabled

  # These are pulled from the output of the cloudposse/terraform-aws-managed-prometheus module
  additional_allowed_roles = compact([for prometheus in module.prometheus : prometheus.outputs.access_role_arn])
}

module "security_group" {
  source  = "cloudposse/security-group/aws"
  version = "2.2.0"

  enabled = local.enabled && var.private_network_access_enabled

  allow_all_egress = true
  rules            = []
  vpc_id           = module.vpc.outputs.vpc_id

  context = module.this.context
}

module "managed_grafana" {
  source  = "cloudposse/managed-grafana/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"

  enabled = local.enabled

  prometheus_policy_enabled = var.prometheus_policy_enabled
  additional_allowed_roles  = local.additional_allowed_roles

  sso_role_associations = [
    {
      "role" = "ADMIN"
      "group_ids" = ["xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"]
    }
  ]

  vpc_configuration = var.private_network_access_enabled ? {
    subnet_ids         = module.vpc.outputs.private_subnet_ids
    security_group_ids = [module.security_group.id]
  } : {}

  context = module.this.context
}

Examples​

Here is an example of using this module:

Variables​

Required Variables​

Optional Variables​

additional_allowed_roles (list(string)) optional

A list of IAM Role ARNs that this Grafana IAM role will be allowed to assume. Use this to set up cross-account access.


Default value: [ ]

authentication_providers (list(string)) optional

The authentication providers for the workspace. Valid values are AWS_SSO, SAML, or both.


Default value:

[
  "AWS_SSO"
]
permission_type (string) optional

The permission type of the workspace. If SERVICE_MANAGED is specified, the IAM roles and IAM policy attachments are generated automatically. If CUSTOMER_MANAGED is specified, the IAM roles and IAM policy attachments will not be created.


Default value: "SERVICE_MANAGED"

prometheus_policy_enabled (bool) optional

Set this to true to allow this Grafana workspace to access Amazon Managed Prometheus (AMP).


Default value: false

sso_role_associations optional

A list of role to group ID list associations for granting Amazon Grafana access. Only used if var.authentication_providers includes AWS_SSO


Type:

list(object({
role      = string
group_ids = list(string)
}))

Default value: [ ]

vpc_configuration optional

If defined, this map defines the VPC configuration to connect your Grafana workspace to a private network


Type:

object({
security_group_ids = list(string)
subnet_ids         = list(string)
})

Default value: null

Context Variables​

The following variables are defined in the context.tf file of this module and part of the terraform-null-label pattern.

additional_tag_map (map(string)) optional

Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id.
This is for some rare cases where resources want additional configuration of tags
and therefore take a list of maps with tag key, value, and additional configuration.


Required: No

Default value: { }

attributes (list(string)) optional

ID element. Additional attributes (e.g. workers or cluster) to add to id,
in the order they appear in the list. New attributes are appended to the
end of the list. The elements of the list are joined by the delimiter
and treated as a single ID element.


Required: No

Default value: [ ]

context (any) optional

Single object for setting entire context at once.
See description of individual variables for details.
Leave string and numeric variables as null to use default value.
Individual variable settings (non-null) override settings in context object,
except for attributes, tags, and additional_tag_map, which are merged.


Required: No

Default value:

{
  "additional_tag_map": {},
  "attributes": [],
  "delimiter": null,
  "descriptor_formats": {},
  "enabled": true,
  "environment": null,
  "id_length_limit": null,
  "label_key_case": null,
  "label_order": [],
  "label_value_case": null,
  "labels_as_tags": [
    "unset"
  ],
  "name": null,
  "namespace": null,
  "regex_replace_chars": null,
  "stage": null,
  "tags": {},
  "tenant": null
}
delimiter (string) optional

Delimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.


Required: No

Default value: null

descriptor_formats (any) optional

Describe additional descriptors to be output in the descriptors output map.
Map of maps. Keys are names of descriptors. Values are maps of the form
\{<br/> format = string<br/> labels = list(string)<br/> \}
(Type is any so the map values can later be enhanced to provide additional options.)
format is a Terraform format string to be passed to the format() function.
labels is a list of labels, in order, to pass to format() function.
Label values will be normalized before being passed to format() so they will be
identical to how they appear in id.
Default is {} (descriptors output will be empty).


Required: No

Default value: { }

enabled (bool) optional

Set to false to prevent the module from creating any resources
Required: No

Default value: null

environment (string) optional

ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'
Required: No

Default value: null

id_length_limit (number) optional

Limit id to this many characters (minimum 6).
Set to 0 for unlimited length.
Set to null for keep the existing setting, which defaults to 0.
Does not affect id_full.


Required: No

Default value: null

label_key_case (string) optional

Controls the letter case of the tags keys (label names) for tags generated by this module.
Does not affect keys of tags passed in via the tags input.
Possible values: lower, title, upper.
Default value: title.


Required: No

Default value: null

label_order (list(string)) optional

The order in which the labels (ID elements) appear in the id.
Defaults to ["namespace", "environment", "stage", "name", "attributes"].
You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.


Required: No

Default value: null

label_value_case (string) optional

Controls the letter case of ID elements (labels) as included in id,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the tags input.
Possible values: lower, title, upper and none (no transformation).
Set this to title and set delimiter to "" to yield Pascal Case IDs.
Default value: lower.


Required: No

Default value: null

labels_as_tags (set(string)) optional

Set of labels (ID elements) to include as tags in the tags output.
Default is to include all labels.
Tags with empty values will not be included in the tags output.
Set to [] to suppress all generated tags.
Notes:
The value of the name tag, if included, will be the id, not the name.
Unlike other null-label inputs, the initial setting of labels_as_tags cannot be
changed in later chained modules. Attempts to change it will be silently ignored.


Required: No

Default value:

[
  "default"
]
name (string) optional

ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'.
This is the only ID element not also included as a tag.

Required: No

Default value: null

Required: No

Default value: null

regex_replace_chars (string) optional

Terraform regular expression (regex) string.
Characters matching the regex will be removed from the ID elements.

Required: No

Default value: null

stage (string) optional

ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'

tenant (string) optional

ID element (Rarely used, not included by default). A customer identifier, indicating who this instance of a resource is for
