Creating policies and non-administrative roles

By default, users and roles don't have permission to create or modify MediaPackage resources. They also can't perform tasks by using the AWS Management Console, AWS Command Line Interface (AWS CLI), or AWS API. To grant users permission to perform actions on the resources that they need, an IAM administrator can create IAM policies. The administrator can then add the IAM policies to roles, and users can assume the roles.

To learn how to create an IAM identity-based policy by using these example JSON policy documents, see Create IAM policies (console) in the IAM User Guide.

For details about actions and resource types defined by MediaPackage, including the format of the ARNs for each of the resource types, see Actions, resources, and condition keys for AWS Elemental MediaPackage in the Service Authorization Reference.

This section describes how you can create policies and create non-administrative roles so that users can create or modify MediaPackage resources. This section also describes how your users can assume that role to grant secure and temporary credentials.

(Optional) Step 1: Create an IAM policy for Amazon CloudFront

If you or your users will create Amazon CloudFront distributions from the AWS Elemental MediaPackage live console, create an IAM policy that allows access to CloudFront.

For more information about using CloudFront with MediaPackage, see Working with CDNs.

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 the following JSON policy document:

   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Action": [
                   "cloudfront:GetDistribution",
                   "cloudfront:CreateDistributionWithTags",
                   "cloudfront:UpdateDistribution",
                   "cloudfront:CreateDistribution",
                   "cloudfront:TagResource",
                   "tag:GetResources"
               ],
               "Resource": "*"
           }
       ]
   }

6. 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. 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.

8. Choose Create policy to save your new policy.

(Optional) Step 2: Create an IAM policy for MediaPackage VOD

If you or your users will be using video on demand (VOD) functionality in MediaPackage, create an IAM policy that allows access to resources for the mediapackage-vod service.

The following sections describe how to create a policy that allows all actions, and one that allows read-only rights. You can customize the policies by adding or removing actions to fit your workflows.

Policy for full VOD access

This policy allows the user to perform all actions on all VOD resources.

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 the following JSON policy document:

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

6. 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. 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.

8. Choose Create policy to save your new policy.

Policy for read-only VOD access

This policy allows the user to view all VOD resources.

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 the following JSON policy document:

   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Action": [
                   "mediapackage-vod:List*",
                   "mediapackage-vod:Describe*"
               ],
               "Resource": "*"
           }
       ]
   }

6. 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. 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.

8. Choose Create policy to save your new policy.

Step 3: Create a role in the IAM console

Create a role in the IAM console for each policy that you create. This allows users to assume a role rather than attaching individual policies to each user.

To create a role in the IAM 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 of the IAM console, choose Roles, and then choose Create role.

3. Under Select trusted entity, choose AWS account.

4. Under An AWS account, select the account with the users that will be assuming this role.

   • If a third-party will be accessing this role, it's best practice to select Require external ID. For more information about external IDs, see Using an external ID for third-party access in the IAM User Guide.

   • It's best practice to require multi-factor authentication (MFA). You can select the check box next to Require MFA. For more information about MFA, see Multi-factor authentication (MFA) in the IAM User Guide.

5. Choose Next.

6. Under Permissions policies, search for and add the policy with the appropriate MediaPackage permissions level.

   • For access to live functionality, choose one of the following options:

     • Use AWSElementalMediaPackageFullAccess to allow the user to perform all actions on all live resources in MediaPackage.

     • Use AWSElementalMediaPackageReadOnly to provide the user read-only rights for all live resources in MediaPackage.

   • For access to video on demand (VOD) functionality, use the policy that you created in (Optional) Step 2: Create an IAM policy for MediaPackage VOD.

7. Add policies to allow the MediaPackage console to make calls to Amazon CloudWatch on the user's behalf. Without these policies, the user is able to use the service's API only (not the console). Choose one of the following options:

   • Use ReadOnlyAccess to allow MediaPackage to communicate with CloudWatch, and also provide the user read-only access to all AWS services on your account.

   • Use CloudWatchReadOnlyAccess, CloudWatchEventsReadOnlyAccess, and CloudWatchLogsReadOnlyAccess to allow MediaPackage to communicate with CloudWatch, and limit the user's read-only access to CloudWatch.

8. (Optional) If this user will create Amazon CloudFront distributions from the MediaPackage console, attach the policy that you created in (Optional) Step 1: Create an IAM policy for Amazon CloudFront.

9. (Optional) Set a permissions boundary. This is an advanced feature that is available for service roles, but not service-linked roles.

   1. Expand the Permissions boundary section and choose Use a permissions boundary to control the maximum role permissions. IAM includes a list of the AWS managed and customer managed policies in your account.

   2. Select the policy to use for the permissions boundary or choose Create policy to open a new browser tab and create a new policy from scratch. For more information, see Creating IAM policies in the IAM User Guide.

   3. After you create the policy, close that tab and return to your original tab to select the policy to use for the permissions boundary.

10. Verify that the correct policies are added to this group, and then choose Next.

11. If possible, enter a role name or role name suffix to help you identify the purpose of this role. Role names must be unique within your AWS account. They are not distinguished by case. For example, you cannot create roles named both PRODROLE and prodrole. Because various entities might reference the role, you cannot edit the name of the role after it has been created.

12. (Optional) For Description, enter a description for the new role.

13. Choose Edit in the Step 1: Select trusted entities or Step 2: Select permissions sections to edit the use cases and permissions for the role.

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

15. Review the role and then choose Create role.

Step 4: Assume the role from the IAM console or AWS CLI

View the following resources for learning about granting permissions for users to assume the role and how users can switch to the role from the IAM console or AWS CLI.

• For more information about granting a user permissions to switch roles, see Granting a user permissions to switch roles in the IAM User Guide.

• For more information about switching roles (console), see Switching to a role (console) in the IAM User Guide.

• For more information about switching roles (AWS CLI), see Switching to an IAM role (AWS CLI) in the IAM User Guide.
