Step 2: Create a user and policy - Amazon DynamoDB

Step 2: Create a user and policy

In this step, you create a user with a policy that grants access to your Amazon DynamoDB Accelerator (DAX) cluster and to DynamoDB using AWS Identity and Access Management. You can then run applications that interact with your DAX cluster.

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.

To provide access, add permissions to your users, groups, or roles:

To use the JSON policy editor to create a policy
  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 on the left, choose Policies.

    If this is your first time choosing Policies, the Welcome to Managed Policies page appears. Choose Get Started.

  3. At the top of the page, choose Create policy.

  4. In the Policy editor section, choose the JSON option.

  5. Enter or paste a JSON policy document. For details about the IAM policy language, see IAM JSON policy reference.

  6. Resolve any security warnings, errors, or general warnings generated during policy validation, and then choose Next.

    Note

    You can switch between the Visual and JSON editor options anytime. However, if you make changes or choose Next in the Visual editor, IAM might restructure your policy to optimize it for the visual editor. For more information, see Policy restructuring in the IAM User Guide.

  7. (Optional) When you create or edit a policy in the AWS Management Console, you can generate a JSON or YAML policy template that you can use in AWS CloudFormation templates.

    To do this, in the Policy editor choose Actions, and then choose Generate CloudFormation template. To learn more about AWS CloudFormation, see AWS Identity and Access Management resource type reference in the AWS CloudFormation User Guide.

  8. When you are finished adding permissions to the policy, choose Next.

  9. On the Review and create page, enter a Policy name and a Description (optional) for the policy that you are creating. Review Permissions defined in this policy to see the permissions that are granted by your policy.

  10. (Optional) Add metadata to the policy by attaching tags as key-value pairs. For more information about using tags in IAM, see Tagging IAM resources in the IAM User Guide.

  11. Choose Create policy to save your new policy.

Policy document – Copy and paste the following document to create the JSON policy.

{ "Version": "2012-10-17", "Statement": [ { "Action": [ "dax:*" ], "Effect": "Allow", "Resource": [ "*" ] }, { "Action": [ "dynamodb:*" ], "Effect": "Allow", "Resource": [ "*" ] } ] }
