Setting up Amazon FSx for Lustre - FSx for Lustre

Setting up Amazon FSx for Lustre

Before you use Amazon FSx for Lustre for the first time, complete the tasks in the Sign up for Amazon Web Services section. To complete the Getting started tutorial, make sure the Amazon S3 bucket that you'll link to your file system has the permissions listed in Adding permissions to use data repositories in Amazon S3.

Sign up for Amazon Web Services

To set up for AWS, complete the following tasks:

Sign up for an AWS account

If you do not have an AWS account, complete the following steps to create one.

To sign up for an AWS account
  1. Open https://portal.aws.amazon.com/billing/signup.

  2. Follow the online instructions.

    Part of the sign-up procedure involves receiving a phone call and entering a verification code on the phone keypad.

    When you sign up for an AWS account, an AWS account root user is created. The root user has access to all AWS services and resources in the account. As a security best practice, assign administrative access to an administrative user, and use only the root user to perform tasks that require root user access.

AWS sends you a confirmation email after the sign-up process is complete. At any time, you can view your current account activity and manage your account by going to https://aws.amazon.com/ and choosing My Account.

Create an administrative user

After you sign up for an AWS account, secure your AWS account root user, enable AWS IAM Identity Center, and create an administrative user so that you don't use the root user for everyday tasks.

Secure your AWS account root user
  1. Sign in to the AWS Management Console as the account owner by choosing Root user and entering your AWS account email address. On the next page, enter your password.

    For help signing in by using root user, see Signing in as the root user in the AWS Sign-In User Guide.

  2. Turn on multi-factor authentication (MFA) for your root user.

    For instructions, see Enable a virtual MFA device for your AWS account root user (console) in the IAM User Guide.

Create an administrative user
  1. Enable IAM Identity Center.

    For instructions, see Enabling AWS IAM Identity Center in the AWS IAM Identity Center User Guide.

  2. In IAM Identity Center, grant administrative access to an administrative user.

    For a tutorial about using the IAM Identity Center directory as your identity source, see Configure user access with the default IAM Identity Center directory in the AWS IAM Identity Center User Guide.

Sign in as the administrative user
  • To sign in with your IAM Identity Center user, use the sign-in URL that was sent to your email address when you created the IAM Identity Center user.

    For help signing in using an IAM Identity Center user, see Signing in to the AWS access portal in the AWS Sign-In User Guide.

Adding permissions to use data repositories in Amazon S3

Amazon FSx for Lustre is deeply integrated with Amazon S3. This integration means that applications that access your FSx for Lustre file system can also seamlessly access the objects stored in your linked Amazon S3 bucket. For more information, see Using data repositories with Amazon FSx for Lustre.

To use data repositories, you must first allow Amazon FSx for Lustre certain IAM permissions in a role associated with the account for your administrator user.

To embed an inline policy for a role using the console
  1. Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com//iam/.

  2. In the navigation pane, choose Roles.

  3. In the list, choose the name of the role to embed a policy in.

  4. Choose the Permissions tab.

  5. Scroll to the bottom of the page and choose Add inline policy.

    Note

    You can't embed an inline policy in a service-linked role in IAM. Because the linked service defines whether you can modify the permissions of the role, you might be able to add additional policies from the service console, API, or AWS CLI. To view the service-linked role documentation for a service, see AWS Services That Work with IAM and choose Yes in the Service-Linked Role column for your service.

  6. Choose Creating Policies with the Visual Editor

  7. Add the following permissions policy statement.

    { "Version": "2012-10-17", "Statement": { "Effect": "Allow", "Action": [ "iam:CreateServiceLinkedRole", "iam:AttachRolePolicy", "iam:PutRolePolicy" ], "Resource": "arn:aws:iam::*:role/aws-service-role/s3.data-source.lustre.fsx.amazonaws.com/*" } }

After you create an inline policy, it is automatically embedded in your role. For more information about service-linked roles, see Using service-linked roles for Amazon FSx.

How FSx for Lustre checks for access to linked S3 buckets

If the IAM role that you use to create the FSx for Lustre file system does not have the iam:AttachRolePolicy and iam:PutRolePolicy permissions, then Amazon FSx checks whether it can update your S3 bucket policy. Amazon FSx can update your bucket policy if the s3:PutBucketPolicy permission is included in your IAM role to allow the Amazon FSx file system to import or export data to your S3 bucket. If allowed to modify the bucket policy, Amazon FSx adds the following permissions to the bucket policy:

  • s3:AbortMultipartUpload

  • s3:DeleteObject

  • s3:PutObject

  • s3:Get*

  • s3:List*

  • s3:PutBucketNotification

  • s3:PutBucketPolicy

  • s3:DeleteBucketPolicy

If Amazon FSx can't modify the bucket policy, it then checks if the existing bucket policy grants Amazon FSx access to the bucket.

If all of these options fail, then the request to create the file system fails. The following diagram illustrates the checks that Amazon FSx follows when determining whether a file system can access the S3 bucket to which it will be linked.
