Component: efs

This component is responsible for provisioning an EFS Network File System with KMS encryption-at-rest. EFS is an excellent choice as the default block storage for EKS clusters so that volumes are not zone-locked.

Usage

Stack Level: Regional

Here’s an example snippet for how to use this component.

components:
  terraform:

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. object({ enabled = bool namespace = string environment = string stage = string name = string delimiter = string attributes = list(string) tags = map(string) additional_tag_map = map(string) regex_replace_chars = string label_order = list(string) id_length_limit = number }) { “additional_tag_map”: {}, “attributes”: [], “delimiter”: null, “enabled”: true, “environment”: null, “id_length_limit”: null, “label_order”: [], “name”: null, “namespace”: null, “regex_replace_chars”: null, “stage”: null, “tags”: {}} no

import_role_arn IAM Role ARN to use when importing a resource string null no
label_order The naming order of the id output and Name tag.Defaults to [“namespace”, “environment”, “stage”, “name”, “attributes”].You can omit any of the 5 elements, but at least one must be present. list(string) null no
name Solution name, e.g. ‘app’ or ‘jenkins’ string null no
namespace Namespace, which could be your organization name or abbreviation, e.g. ‘eg’ or ‘cp’ string null no
performance_mode The file system performance mode. Can be either generalPurpose or maxIO string "generalPurpose" no
provisioned_throughput_in_mibps The throughput, measured in MiB/s, that you want to provision for the file system. Only applicable with throughput_mode set to provisioned number 0 no
regex_replace_chars Regex to replace chars with empty string in namespace, environment, stage and name.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
stage Stage, e.g. ‘prod’, ‘staging’, ‘dev’, OR ‘source’, ‘build’, ‘test’, ‘deploy’, ‘release’ string null no
tags Additional tags (e.g. map('BusinessUnit','XYZ') map(string) {} no
tfstate_account_id The ID of the account where the Terraform remote state backend is provisioned string "" no
tfstate_assume_role Set to false to use the caller’s role to access the Terraform remote state bool true no
tfstate_bucket_environment_name The name of the environment for Terraform state bucket string "" no
tfstate_bucket_stage_name The name of the stage for Terraform state bucket string "root" no
tfstate_existing_role_arn The ARN of the existing IAM Role to access the Terraform remote state. If not provided and remote_state_assume_role is true, a role will be constructed from remote_state_role_arn_template string "" no
tfstate_role_arn_template IAM Role ARN template for accessing the Terraform remote state string "arn:aws:iam::%s:role/%s-%s-%s-%s" no
tfstate_role_environment_name The name of the environment for Terraform state IAM role string "gbl" no
tfstate_role_name IAM Role name for accessing the Terraform remote state string "terraform" no
tfstate_role_stage_name The name of the stage for Terraform state IAM role string "root" no
throughput_mode Throughput mode for the file system. Defaults to bursting. Valid values: bursting, provisioned. When using provisioned, also set provisioned_throughput_in_mibps string "bursting" no
