Examples

Examples codified under the examples are intended to give users references for how to use the module(s) as well as testing/validating changes to the source code of the module. If contributing to the project, please be sure to make any appropriate updates to the relevant examples to allow maintainers to test your changes and to keep the examples up to date for users. Thank you!

Inputs

Name Description Type Default Required
access_points A map of access point definitions to create any {} no
attach_policy Determines whether a policy is attached to the file system bool true no
availability_zone_name The AWS Availability Zone in which to create the file system. Used to create a file system that uses One Zone storage classes string null no
bypass_policy_lockout_safety_check A flag to indicate whether to bypass the aws_efs_file_system_policy lockout safety check. Defaults to false bool null no
create Determines whether resources will be created (affects all resources) bool true no
create_backup_policy Determines whether a backup policy is created bool true no
create_replication_configuration Determines whether a replication configuration is created bool false no
create_security_group Determines whether a security group is created bool true no
creation_token A unique name (a maximum of 64 characters are allowed) used as reference when creating the Elastic File System to ensure idempotent file system creation. By default generated by Terraform string null no
deny_nonsecure_transport Determines whether aws:SecureTransport is required when connecting to elastic file system bool true no
enable_backup_policy Determines whether a backup policy is ENABLED or DISABLED bool true no
encrypted If true, the disk will be encrypted bool true no

name The name of the file system string "" no
override_policy_documents List of IAM policy documents that are merged together into the exported document. In merging, statements with non-blank sids will override statements with the same sid list(string) [] no

security_group_description Security group description. Defaults to Managed by Terraform string null no
security_group_name Name to assign to the security group. If omitted, Terraform will assign a random, unique name string null no
security_group_rules Map of security group rule definitions to create any {} no
security_group_use_name_prefix Determines whether to use a name prefix for the security group. If true, the security_group_name value will be used as a prefix bool false no
security_group_vpc_id The VPC ID where the security group will be created string null no
source_policy_documents List of IAM policy documents that are merged together into the exported document. Statements must have unique sids list(string) [] no
tags A map of tags to add to all resources map(string) {} no
throughput_mode Throughput mode for the file system. Defaults to bursting. Valid values: bursting, elastic, and provisioned. When using provisioned, also set provisioned_throughput_in_mibps string null no

Outputs

Name Description
access_points Map of access points created and their attributes
arn Amazon Resource Name of the file system
dns_name The DNS name for the filesystem per documented convention
id The ID that identifies the file system (e.g., fs-ccfc0d65)
mount_targets Map of mount targets created and their attributes
replication_configuration_destination_file_system_id The file system ID of the replica
security_group_arn ARN of the security group
security_group_id ID of the security group
size_in_bytes The latest known metered size (in bytes) of data stored in the file system, the value is not the exact size that the file system was at any point in time
