Create roles - MediaLive

Create roles

Any person who is an administrator can perform the procedure to create a role and attach policies to the role.

In Identify the access requirements, someone in your organization identified the roles that you need to create. Create those roles now using IAM.

In this step, you create a role that consists of a trust policy ("let MediaLive call the AssumeRole action") and one or more policies (the policies that you just created). In this way, MediaLive has permission to assume the role. When it assumes the role, it acquires the permissions specified in the policies.

Follow this procedure for each role.

  1. On the IAM console, in the navigation pane on the left, choose Roles, then Create Role. The Create role wizard appears. This wizard walks you through the steps of setting up a trusted entity, and adding permissions (by adding a policy).

  2. On the Select trusted entity page, choose the Custom trust policy card. The Custom trust policy section appears, with a sample policy.

  3. Erase the sample, copy the following text, and paste the text in the Custom trust policy section. The Custom trust policy section now looks like this:

    {
    "Version": "2012-10-17",
    "Statement": [
	{
            "Effect": "Allow",
            "Principal": {
                "Service": "medialive.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}

  4. Choose Next.

  5. On the Add Permissions page, find the policy or policies that you created (for example, MedialiveForCurlingEvents), and select the checkbox for each. Then choose Next.

  6. On the review page, enter a name for the role. We recommend that you don't use the name MediaLiveAccessRole because it is reserved for the simple option.

    Instead, use a name that includes Medialive and describes this role's purpose. For example, MedialiveAccessRoleForSports.

  7. Choose Create role.

  8. On the Summary page for the role, make a note of the value in Role ARN. It looks like this:

    arn:aws:iam::111122223333:role/medialiveWorkflow15

    In the example, 111122223333 is your AWS account number.

  9. After you have created all the roles, make a list of the role ARNs. Include the following information in each item:

    • The role ARN.

    • A description of the workflow that the ARN applies to.

    • The users who can work with this workflow and therefore need the ability to attach this trust policy to the channels that they create and edit.

    You will need this list when you set up trusted entity access for users.
