terraform-aws-ecs-cluster

Terraform module to provision an ECS Cluster.

---

Providers

This modules uses two instances of the AWS provider. One for Route 53 resources and one for the rest. The reason why is that Route 53 is often in a different account (ie. in the prod account when creating resources for dev).

You must provide both providers, whether you use Route 53 or not. In any case, you can specify the same provider for both if need be.

Examples

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.

module "ecs_cluster" {
  source = "nventive/ecs-cluster/aws"
  # We recommend pinning every module to a specific version
  # version = "x.x.x"

  namespace = "eg"
  stage     = "test"
  name      = "app"

  providers = {
    aws         = aws
    aws.route53 = aws.route53
  }
  subnet_ids       = ["subnet-xxxxxxxxxxxxxxxx1", "subnet-xxxxxxxxxxxxxxxx2"]
  parent_zone_name = "example.com"
  alb_enabled      = true
  alb_dns_aliases  = ["test.example.com", "demo.example.com"]
}

Should you want to use the same AWS provider for both Route 53 and the default one.

module "ecs_cluster" {
  source = "nventive/ecs-cluster/aws"
  # We recommend pinning every module to a specific version
  # version = "x.x.x"

  providers = {
    aws         = aws
    aws.route53 = aws
  }

  # ...
}

Inputs

Name	Description	Type	Default	Required
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
alb_access_logs_enabled	Whether or not ALB access logs should be enabled.	bool	true	no
alb_access_logs_force_destroy	Whether or not force destroy option should be enabled for the ALB access logs Bucket.	bool	true	no
alb_access_logs_prefix	Prefix for ALB access logs.	string	""	no
alb_arn	Set if you want to use an existing Application Load Balancer.	string	""	no
alb_dns_aliases	List of custom domain name aliases for ALB.	list(string)	[]	no
alb_enabled	Set to false to prevent the module from creating an Application Load Balancer. This setting defaults to false if alb_arn is specified.	bool	true	no
alb_internal	Set to true to make the ALB internal.	bool	false	no
alb_ip_address_type	Address type for ALB possible. Specify one of ipv4, dualstack. Only when alb_enabled = true.	string	null	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
cloudwatch_log_group_retention_in_days	Number of days to retain Cloudwatch logs.	number	60	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
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
ecs_cluster_container_insights_enabled	Whether or not Container Insights should be enabled.	bool	true	no
enabled	Set to false to prevent the module from creating any resources	bool	null	no
environment	ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'	string	null	no
id_length_limit	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.	number	null	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
logs_kms_key_arn	ARN of the KMS key for CloudWatch encryption, if blank, one will be created.	string	""	no
name	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. The "name" tag is set to the full id string. There is no tag with the value of the name input.	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
parent_zone_id	ID of the hosted zone to contain this record (or specify parent_zone_name). Requires dns_alias_enabled set to true.	string	null	no
parent_zone_name	Name of the hosted zone to contain this record (or specify parent_zone_id). Requires dns_alias_enabled set to true.	string	null	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
stage	ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'	string	null	no
subnet_ids	List of subnet IDs for the Load Balancer. The Load Balancer will be created in the VPC associated with the subnet IDs.	list(string)	[]	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
