DMS for RabbitMQ Custom Policies

Custom policies can be created to supplement the system-defined policies of DMS for RabbitMQ. For the actions that can be added for custom policies, see Permissions Policies and Supported Actions.

You can create custom policies in either of the following ways:

  • Visual editor: Select cloud services, actions, resources, and request conditions. This does not require knowledge of policy syntax.
  • JSON: Edit JSON policies from scratch or based on an existing policy.

For operation details, see Creating a Custom Policy. The following section contains examples of common DMS for RabbitMQ custom policies.

DMS for RabbitMQ permissions policies are based on DMS. Therefore, when assigning permissions, select DMS permissions policies.

Example Custom Policies

  • Example 1: Allowing users to delete and restart instances 
    {
    "Version": "1.1",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "
                     dms:instance:delete
                     dms:instance:modifyStatus
                 "
            ]
        }
    ]
}
  • Example 2: Denying instance deletion

    A policy with only "Deny" permissions must be used in conjunction with other policies to take effect. If the permissions assigned to a user contain both "Allow" and "Deny", the "Deny" permissions take precedence over the "Allow" permissions.

    The following method can be used if you need to assign permissions of the DMS FullAccess policy to a user but you want to prevent the user from deleting instances. Create a custom policy for denying instance deletion, and attach both policies to the group to which the user belongs. Then, the user can perform all operations on DMS except deleting instances. The following is an example of a deny policy:

    {
        "Version": "1.1",
        "Statement": [
                {
                        "Effect": "Deny",
                        "Action": [
                                "dms:instance:delete"
                        ]
                }
        ]
}
