terraform-aws-s3-bucket: An HCL repository from amila-ku

This module creates an S3 bucket with support for versioning, lifecycles, object locks, replication, encryption, ACL, bucket object policies, and static website hosting.

For backward compatibility, it sets the S3 bucket ACL to private and the s3_object_ownership to ObjectWriter. Moving forward, setting s3_object_ownership to BucketOwnerEnforced is recommended, and doing so automatically disables the ACL.

This module blocks public access to the bucket by default. See block_public_acls, block_public_policy, ignore_public_acls, and restrict_public_buckets to change the settings. See AWS documentation for more details.

This module can optionally create an IAM User with access to the S3 bucket. This is inherently insecure in that to enable anyone to become the User, access keys must be generated, and anything generated by Terraform is stored unencrypted in the Terraform state. See the Terraform documentation for more details

The best way to grant access to the bucket is to grant one or more IAM Roles access to the bucket via privileged_principal_arns. This IAM Role can be assumed by EC2 instances via their Instance Profile, or Kubernetes (EKS) services using IRSA. Entities outside of AWS can assume the Role via OIDC. (See this example of connecting GitHub to enable GitHub actions to assume AWS IAM roles, or use this Cloud Posse component if you are already using the Cloud Posse reference architecture.)

If neither of those approaches work, then as a last resort you can set user_enabled = true and this module will provision a basic IAM user with permissions to access the bucket. We do not recommend creating IAM users this way for any other purpose.

If an IAM user is created, the IAM user name is constructed using terraform-null-label and some input is required. The simplest input is name. By default the name will be converted to lower case and all non-alphanumeric characters except for hyphen will be removed. See the documentation for terraform-null-label to learn how to override these defaults if desired.

If an AWS Access Key is created, it is stored either in SSM Parameter Store or is provided as a module output, but not both. Using SSM Parameter Store is recommended because that will keep the secret from being easily accessible via Terraform remote state lookup, but the key will still be stored unencrypted in the Terraform state in any case.

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Usage

Using BucketOwnerEnforced

module "s3_bucket" {
  source = "cloudposse/s3-bucket/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  name                     = "app"
  stage                    = "test"
  namespace                = "eg"

  s3_object_ownership      = "BucketOwnerEnforced"
  enabled                  = true
  user_enabled             = false
  versioning_enabled       = false

  privileged_principal_actions   = ["s3:GetObject", "s3:ListBucket", "s3:GetBucketLocation"]
  privileged_principal_arns      = [
    {
      (local.deployment_iam_role_arn) = [""]
    },
    {
      (local.additional_deployment_iam_role_arn) = ["prefix1/", "prefix2/"]
    }
  ]
}

Configuring S3 storage lifecycle:

locals {
  lifecycle_configuration_rules = [{
    enabled = true # bool
    id      = "v2rule"

    abort_incomplete_multipart_upload_days = 1 # number

    filter_and = null
    expiration = {
      days = 120 # integer > 0
    }
    noncurrent_version_expiration = {
      newer_noncurrent_versions = 3  # integer > 0
      noncurrent_days           = 60 # integer >= 0
    }
    transition = [{
      days          = 30            # integer >= 0
      storage_class = "STANDARD_IA" # string/enum, one of GLACIER, STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING, DEEP_ARCHIVE, GLACIER_IR.
      },
      {
        days          = 60           # integer >= 0
        storage_class = "ONEZONE_IA" # string/enum, one of GLACIER, STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING, DEEP_ARCHIVE, GLACIER_IR.
    }]
    noncurrent_version_transition = [{
      newer_noncurrent_versions = 3            # integer >= 0
      noncurrent_days           = 30           # integer >= 0
      storage_class             = "ONEZONE_IA" # string/enum, one of GLACIER, STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING, DEEP_ARCHIVE, GLACIER_IR.
    }]
  }]
}

Allowing specific principal ARNs to perform actions on the bucket:

module "s3_bucket" {
  source = "cloudposse/s3-bucket/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  s3_object_ownership      = "BucketOwnerEnforced"
  enabled                  = true
  user_enabled             = true
  versioning_enabled       = false
  allowed_bucket_actions   = ["s3:GetObject", "s3:ListBucket", "s3:GetBucketLocation"]
  name                     = "app"
  stage                    = "test"
  namespace                = "eg"

  privileged_principal_arns = [
  {
    "arn:aws:iam::123456789012:role/principal1" = ["prefix1/", "prefix2/"]
  }, {
    "arn:aws:iam::123456789012:role/principal2" = [""]
  }]
  privileged_principal_actions = [
    "s3:PutObject", 
    "s3:PutObjectAcl", 
    "s3:GetObject", 
    "s3:DeleteObject", 
    "s3:ListBucket", 
    "s3:ListBucketMultipartUploads", 
    "s3:GetBucketLocation", 
    "s3:AbortMultipartUpload"
  ]
}

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

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 be changed in later chained modules. Attempts to change it will be silently ignored.	`set(string)`	[ "default" ]	no
