Module: mq-broker

Terraform module to provision AmazonMQ resources on AWS

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.

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.

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 this is false and no egress rules are otherwise specified, then no egress will be allowed.	bool	true	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_cidr_blocks	A list of IPv6 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_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. A list of Security Group IDs to 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
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

deployment_mode	The deployment mode of the broker. Supported: SINGLE_INSTANCE and ACTIVE_STANDBY_MULTI_AZ	string	"ACTIVE_STANDBY_MULTI_AZ"	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

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

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
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

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
