Scenario3: Owned EFS and Owned EFS Access Point

This example assumes following resources are already provisioned:

• EFS file system does not exist. It is owned by the SFTP server.
• EFS access point does not exist. It is owned by the SFTP server.
• EFS mount points do not exist. It will be created along with the EFS.
• EFS Security Group does not exist. It will be created along with the EFS.
• The target VPC and Subnets exists and tagged for identification.

Prerequisites

• Terraform backend provider and state locking providers are identified and bootstrapped.
  • A bootstrap module/example is provided that provisions Amazon S3 for Terraform state storage and Amazon DynamoDB for Terraform state locking.
• The target VPC along with the target Subnets exist and identified via Tags.
  • A vpc example is provided that provisions VPC, Subnets and related resources with example tagging.
  • The example uses the following tags to identify the target VPC and Subnets.

    "transfer/sftp/efs" = "1"
    "Env"               = "DEV"
    

• Create a ssh key-pair for each SFTP client authentication. Or obtain the public key from the SFTP client.
  • Copy the public key(s) in the users folder e.g. users/test.pub
• Modify terraform.tfvars to match your requirements. Check the values for the following variables.
  • efs_id --> null, EFS will be created.
  • efs_ap_id --> null, EFA Access Point will be created.
  • efs_sg_tags --> null, EFS Security Group will be created.
  • efs_kms_alias --> "", EFS KMS CMK will be created, if required.
  • sftp_users --> list of users along with unique POSIX profile and ssh public key.
  • sftp_user_automation_subscribers --> list of email addresses.
  • sftp_daily_report_subscribers --> list of email addresses.

Execution

• cd to examples/sftp/scenario3 folder.
• Modify backend "S3" section in the provider.tf with correct values for region, bucket, dynamodb_table, and key.
  • Use provided values as guidance.
• Modify terraform.tfvars to your requirements.
  • Use provided values as guidance.
• Make sure you are using the correct AWS Profile that has permission to provision the target resources.
  • aws sts get-caller-identity
• Execute terraform init to initialize Terraform.
• Execute terraform plan and verify the changes.
• Execute terraform apply and approve the changes to provision the resources.
• The email subscribers must confirm the subscription to receive the status and the activity emails.

Use SFTP client of your choice to test the SFTP server.
