terraform-aws-mq-broker

Terraform module to provision AmazonMQ resources on AWS

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Introduction

This module provisions the following resources:

ActiveMQ broker
RabbitMQ broker
Security group rules to allow access to the broker

Admin and application users are created and credentials written to SSM if not passed in as variables.

Security & Compliance

Security scanning is graciously provided by Bridgecrew. Bridgecrew is the leading fully hosted, cloud-native solution providing continuous Terraform security and compliance.

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

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.

  module "mq_broker" {
    source = "cloudposse/mq-broker/aws"
    # Cloud Posse recommends pinning every module to a specific version
    # version     = "x.x.x"

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

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
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

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_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

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

overwrite_ssm_parameter	Whether to overwrite an existing SSM parameter	`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
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.	`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_path	The first parameter to substitute in `ssm_parameter_name_format`	`string`	`"mq"`	no

subnet_ids	List of VPC subnet IDs	`list(string)`	n/a	yes
