This component is responsible for provisioning an AmazonMQ broker and the corresponding security group.

Migrate `v1` to `v2`

EKS component dependency removed. Instead of pulling security groups from EKS remote state, pass it as var.allowed_security_groups. If you are using Atmos, read atmos shared data manual.

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform

Example of running atmos to manage infrastructure from our Quick Start tutorial.

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Inputs

Name	Description	Type	Default	Required
additional_security_group_rules	A list of Security Group rule objects to add to the created security group, in addition to the ones this module normally creates. (To suppress the module's rules, set `create_security_group` to false and supply your own security group(s) via `associated_security_group_ids`.) The keys and values of the objects are fully compatible with the `aws_security_group_rule` resource, except for `security_group_id` which will be ignored, and the optional "key" which, if provided, must be unique and known at "plan" time. For more info see https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/security_group_rule and https://github.com/cloudposse/terraform-aws-security-group.	`list(any)`	`[]`	no
additional_tag_map	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.	`map(string)`	`{}`	no
allow_all_egress	If `true`, the created security group will allow egress on all ports and protocols to all IP addresses. If `false`, no egress rules will be created by this module; egress must be configured via other means (e.g. additional security group rules) or all outbound traffic will be denied.	`bool`	`true`	no
allowed_cidr_blocks	A list of IPv4 CIDRs to allow access to the security group created by this module. The length of this list must be known at "plan" time.	`list(string)`	`[]`	no
allowed_ingress_ports	List of TCP ports to allow access to in the created security group. Default is to allow access to all ports. Set `create_security_group` to `false` to disable. Note: List of ports must be known at "plan" time.	`list(number)`	`[]`	no

allowed_ipv6_prefix_list_ids	A list of IPv6 Prefix Lists IDs to allow access to the security group created by this module. The length of this list must be known at "plan" time.	`list(string)`	`[]`	no
allowed_security_group_ids	A list of IDs of Security Groups to allow access to the security group created by this module. The length of this list must be known at "plan" time.	`list(string)`	`[]`	no
allowed_security_groups	DEPRECATED: Use `allowed_security_group_ids` instead. List of Security Group IDs to be allowed to connect to the broker instance.	`list(string)`	`[]`	no
apply_immediately	Specifies whether any cluster modifications are applied immediately, or during the next maintenance window	`bool`	`false`	no
associated_security_group_ids	A list of IDs of Security Groups to associate the created resource with, in addition to the created security group. These security groups will not be modified and, if `create_security_group` is `false`, must have rules providing the desired access.	`list(string)`	`[]`	no
attributes	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.	`list(string)`	`[]`	no
audit_log_enabled	Enables audit logging. User management action made using JMX or the ActiveMQ Web Console is logged	`bool`	`true`	no
auto_minor_version_upgrade	Enables automatic upgrades to new minor versions for brokers, as Apache releases the versions	`bool`	`false`	no
configuration_data	Data value for broker configuration (e.g. broker configuration XML)	`string`	`null`	no
context	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.	`any`	{ "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 }	no
create_security_group	Set `true` to create and configure a new security group. If false, `associated_security_group_ids` must be provided.	`bool`	`true`	no
delimiter	Delimiter to be used between ID elements. Defaults to `-` (hyphen). Set to `""` to use no delimiter at all.	`string`	`null`	no

descriptor_formats	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).	`any`	`{}`	no

kms_mq_key_arn	ARN of the AWS KMS key used for Amazon MQ encryption	`string`	`null`	no
kms_ssm_key_arn	ARN of the AWS KMS key used for SSM encryption	`string`	`"alias/aws/ssm"`	no
label_key_case	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`.	`string`	`null`	no
label_order	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.	`list(string)`	`null`	no
label_value_case	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`.	`string`	`null`	no
labels_as_tags	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.	`set(string)`	[ "default" ]	no
maintenance_day_of_week	The maintenance day of the week. e.g. MONDAY, TUESDAY, or WEDNESDAY	`string`	`"SUNDAY"`	no
maintenance_time_of_day	The maintenance time, in 24-hour format. e.g. 02:00	`string`	`"03:00"`	no

namespace	ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique	`string`	`null`	no
overwrite_ssm_parameter	DEPRECATED: No longer used. The underlying `cloudposse/mq-broker/aws` module no longer exposes this input; retained only for backward compatibility and has no effect.	`bool`	`true`	no
preserve_security_group_id	When `false` and `security_group_create_before_destroy` is `true`, changes to security group rules cause a new security group to be created with the new rules, and the existing security group is then replaced with the new one, eliminating any service interruption. When `true` or when changing the value (from `false` to `true` or from `true` to `false`), existing security group rules will be deleted before new ones are created, resulting in a service interruption, but preserving the security group itself. NOTE: Setting this to `true` does not guarantee the security group will never be replaced, it only keeps changes to the security group rules from triggering a replacement. See the terraform-aws-security-group README for further discussion.	`bool`	`false`	no
publicly_accessible	Whether to enable connections from applications outside of the VPC that hosts the broker's subnets	`bool`	`false`	no
regex_replace_chars	Terraform regular expression (regex) string. Characters matching the regex will be removed from the ID elements. If not set, `"/[^a-zA-Z0-9-]/"` is used to remove all characters other than hyphens, letters and digits.	`string`	`null`	no
region	AWS Region	`string`	n/a	yes
security_group_create_before_destroy	Set `true` to enable Terraform `create_before_destroy` behavior on the created security group. We only recommend setting this `false` if you are importing an existing security group that you do not want replaced and therefore need full control over its name. Note that changing this value will always cause the security group to be replaced. NOTE for Amazon MQ (e.g. RabbitMQ): AWS does not support changing the security groups of an existing broker, so a create-before-destroy replacement of the security group forces a full broker recreation. Set this to `false` for brokers to keep the security group stable.	`bool`	`true`	no
security_group_create_timeout	How long to wait for the security group to be created.	`string`	`"10m"`	no
security_group_delete_timeout	How long to retry on `DependencyViolation` errors during security group deletion from lingering ENIs left by certain AWS services such as Elastic Load Balancing.	`string`	`"15m"`	no
security_group_description	The description to assign to the created Security Group. Warning: Changing the description causes the security group to be replaced.	`string`	`"Managed by Terraform"`	no
security_group_name	The name to assign to the created security group. Must be unique within the VPC. If not provided, will be derived from the `null-label.context` passed in. If `create_before_destroy` is true, will be used as a name prefix.	`list(string)`	`[]`	no
ssm_parameter_name_format	SSM parameter name format	`string`	`"/%s/%s"`	no
ssm_parameters_enabled	Whether to create SSM parameters for MQ users and passwords	`bool`	`true`	no
ssm_path	SSM path	`string`	`"mq"`	no
stage	ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'	`string`	`null`	no
tags	Additional tags (e.g. `{'BusinessUnit': 'XYZ'}`). Neither the tag keys nor the tag values will be modified by this module.	`map(string)`	`{}`	no
tenant	ID element _(Rarely used, not included by default)_. A customer identifier, indicating who this instance of a resource is for	`string`	`null`	no
use_aws_owned_key	Boolean to enable an AWS owned Key Management Service (KMS) Customer Master Key (CMK) for Amazon MQ encryption that is not in your account	`bool`	`true`	no
use_existing_security_groups	DEPRECATED: Use `create_security_group` instead. Historical description: Set to `true` to disable Security Group creation and provide a list of existing Security Group IDs in `existing_security_groups` to place the broker into. When non-null, this takes precedence over `create_security_group`.	`bool`	`null`	no
