# Amazon S3 Files File System Creates an Amazon S3 Files file system on a general purpose bucket, with its IAM role, mount targets, access points, file system policy and synchronization configuration. The bucket must have versioning enabled. > [!IMPORTANT] > Pass the versioning resource's own status to `bucket_versioning_status`, as in > `aws_s3_bucket_versioning.this.versioning_configuration[0].status`. That reference is what makes the > file system wait for versioning on create, and be deleted before versioning is suspended on destroy. > A literal `"Enabled"` passes the check and leaves no such ordering, so a destroy can fail with > `BucketHasS3FileSystemAttached`. This applies only when calling this module directly. The root > module's `file_systems` input passes the reference for you. ```hcl module "file_system" { source = "terraform-aws-modules/s3-bucket/aws//modules/file-system" name = "training" bucket_arn = aws_s3_bucket.this.arn bucket_versioning_status = aws_s3_bucket_versioning.this.versioning_configuration[0].status security_group_vpc_id = "vpc-1234556abcdef" security_group_ingress_rules = { clients = { referenced_security_group_id = "sg-1234556abcdef" } } mount_targets = { "eu-west-1a" = { subnet_id = "subnet-1234556abcdef" } } } ``` When the bucket is created by the root module, use its `file_systems` input instead, which calls this module for each entry. ## Requirements | Name | Version | | ---- | ------- | | [terraform](#requirement\_terraform) | >= 1.5.7 | | [aws](#requirement\_aws) | >= 6.44 | ## Providers | Name | Version | | ---- | ------- | | [aws](#provider\_aws) | >= 6.44 | ## Modules No modules. ## Resources | Name | Type | | ---- | ---- | | [aws_iam_role.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/iam_role) | resource | | [aws_iam_role_policy.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/iam_role_policy) | resource | | [aws_iam_role_policy_attachment.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/iam_role_policy_attachment) | resource | | [aws_s3files_access_point.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/s3files_access_point) | resource | | [aws_s3files_file_system.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/s3files_file_system) | resource | | [aws_s3files_file_system_policy.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/s3files_file_system_policy) | resource | | [aws_s3files_mount_target.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/s3files_mount_target) | resource | | [aws_s3files_synchronization_configuration.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/s3files_synchronization_configuration) | resource | | [aws_security_group.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/security_group) | resource | | [aws_vpc_security_group_egress_rule.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpc_security_group_egress_rule) | resource | | [aws_vpc_security_group_ingress_rule.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpc_security_group_ingress_rule) | resource | | [aws_caller_identity.current](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/caller_identity) | data source | | [aws_iam_policy_document.assume_role](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/iam_policy_document) | data source | | [aws_iam_policy_document.policy](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/iam_policy_document) | data source | | [aws_iam_policy_document.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/iam_policy_document) | data source | | [aws_partition.current](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/partition) | data source | | [aws_region.current](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/region) | data source | | [aws_service_principal.elasticfilesystem](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/service_principal) | data source | ## Inputs | Name | Description | Type | Default | Required | | ---- | ----------- | ---- | ------- | :------: | | [accept\_bucket\_warning](#input\_accept\_bucket\_warning) | Whether to acknowledge the warning AWS raises when the bucket holds enough objects that renaming a prefix is slow | `bool` | `null` | no | | [access\_points](#input\_access\_points) | Map of access points to create on the file system.
