Module: eks-iam-role
This terraform-aws-eks-iam-role
project provides a simplified mechanism for provisioning
AWS EKS Service Account IAM roles.
Usage
Here's how to invoke this module in your projects
module "eks_iam_role" {
source = "cloudposse/eks-iam-role/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"
namespace = var.namespace
environment = var.environment
stage = var.stage
name = var.name
delimiter = var.delimiter
attributes = var.attributes
tags = var.tags
aws_account_number = local.account_id
eks_cluster_oidc_issuer_url = module.eks_cluster.eks_cluster_identity_oidc_issuer
# Create a role for the service account named `autoscaler` in the Kubernetes namespace `kube-system`
service_account_name = "autoscaler"
service_account_namespace = "kube-system"
# JSON IAM policy document to assign to the service account role
aws_iam_policy_document = [data.aws_iam_policy_document.autoscaler.json]
}
data "aws_iam_policy_document" "autoscaler" {
statement {
sid = "AllowToScaleEKSNodeGroupAutoScalingGroup"
actions = [
"ec2:DescribeLaunchTemplateVersions",
"autoscaling:TerminateInstanceInAutoScalingGroup",
"autoscaling:SetDesiredCapacity",
"autoscaling:DescribeTags",
"autoscaling:DescribeLaunchConfigurations",
"autoscaling:DescribeAutoScalingInstances",
"autoscaling:DescribeAutoScalingGroups"
]
effect = "Allow"
resources = ["*"]
}
}

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 |
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 |
aws_account_number | AWS account number of EKS cluster owner. If an AWS account number is not provided, the current aws provider account number will be used. | string | null | no |
aws_iam_policy_document | JSON string representation of the IAM policy for this service account as list of string (0 or 1 items). If empty, no custom IAM policy document will be used. If the list contains a single document, a custom IAM policy will be created and attached to the IAM role. Can also be a plain string, but that use is DEPRECATED because of Terraform issues. | any | [] | no |
aws_partition | AWS partition: 'aws', 'aws-cn', or 'aws-us-gov' | string | "aws" | 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 |
| 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 beidentical to how they appear in id .Default is {} (descriptors output will be empty). | any | {} | no |
eks_cluster_oidc_issuer_url | OIDC issuer URL for the EKS cluster (initial "https://" may be omitted) | string | n/a | yes |
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 bechanged in later chained modules. Attempts to change it will be silently ignored. | set(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 |
permissions_boundary | ARN of the policy that is used to set the permissions boundary for the role. | 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 |
service_account_name | Kubernetes ServiceAccount name. Leave empty or set to "*" to indicate all Service Accounts, or if using service_account_namespace_name_list . | string | null | no |
service_account_namespace | Kubernetes Namespace where service account is deployed. Leave empty or set to "*" to indicate all Namespaces, or if using service_account_namespace_name_list . | string | null | no |
service_account_namespace_name_list | List of namespace:name for service account assume role IAM policy if you need more than one. May include wildcards. | list(string) | [] | 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 |
