Module: efs

Terraform module to provision an AWS EFS Network File System.

NOTE: Release 0.32.0 contains breaking changes. To preserve the SG, follow the instructions in the 0.30.1 to 0.32.x+ migration path.

Usage

Include this repository as a module in your existing terraform code:

module "efs" {
source = "cloudposse/efs/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"

namespace = "eg"
stage = "test"
name = "app"
region = "us-west-1"
vpc_id = var.vpc_id
subnets = var.private_subnets
zone_id = [var.aws_route53_dns_zone_id]

allowed_security_group_ids = [var.security_group_id]
}

Inputs

NameDescriptionTypeDefaultRequired
access_pointsA map of the access points you would like in your EFS volume

See [examples/complete] for an example on how to set this up.
All keys are strings. The primary keys are the names of access points.
The secondary keys are posix_user and creation_info.
The secondary_gids key should be a comma separated value.
More information can be found in the terraform resource efs_access_point.
map(map(map(any))){}no
additional_security_group_rulesA 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 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.
To get more info see https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/security_group_rule .
list(any)[]no
additional_tag_mapAdditional 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_egressPassed to the security group module (if one is created).booltrueno
allowed_cidr_blocksThe CIDR blocks from which to allow ingress traffic to the EFSlist(string)[]no
allowed_security_group_idsA list of IDs of Security Groups to allow access to the security group created by this module.list(string)[]no
associated_security_group_idsA list of IDs of Security Groups to associate the EFS Mount Targets 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
attributesID 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
availability_zone_nameAWS Availability Zone in which to create the file system. Used to create a file system that uses One Zone storage classes. If set, a single subnet in the same availability zone should be provided to subnetsstringnullno
bypass_policy_lockout_safety_checkA flag to indicate whether to bypass the aws_efs_file_system_policy lockout safety check.boolfalseno
contextSingle 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.

create_security_groupSet true to create and configure a new security group. If false, associated_security_group_ids must be provided.booltrueno
delimiterDelimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.
stringnullno
descriptor_formatsDescribe 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).

id_length_limitLimit 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.

kms_key_idIf set, use a specific KMS keystringnullno
label_key_caseControls 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.
stringnullno
label_orderThe 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)nullno
label_value_caseControls 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.
stringnullno
labels_as_tagsSet 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.
