Permissions to replicate bots and manage bot replicas in Lex V2

If an IAM role has the AmazonLexFullAccess policy attached, it can create and manage bot replicas.

If you prefer to create a role with minimal permissions for Global Resiliency, use the following policy, which contains the following statements.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "GetReplicationSLR",
            "Effect": "Allow",
            "Action": [
                "iam:GetRole" 
            ],
            "Resource": [
                "arn:aws:iam::*:role/aws-service-role/replication.lexv2.amazonaws.com/AWSServiceRoleForLexV2Replication*"
            ]
        },
        {
            "Sid": "CreateReplicationSLR",
            "Effect": "Allow",
            "Action": [                
                "iam:CreateServiceLinkedRole",                
            ],
            "Resource": [
                "arn:aws:iam::*:role/aws-service-role/replication.lexv2.amazonaws.com/AWSServiceRoleForLexV2Replication*"
            ],
            "Condition": {
                "StringEquals": {
                    "iam:AWSServiceName": "lexv2.amazonaws.com"
                }
            } 
        },
        {
            "Sid": "AllowBotReplicaActions",
            "Effect": "Allow",
            "Action": [
                "lex:CreateBotReplica",
                "lex:DescribeBotReplica",
                "lex:ListBotReplica",
                "lex:ListBotVersionReplicas",
                "lex:ListBotAliasReplicas",
                "lex:DeleteBotReplica"
            ],
            "Resource": [
                "arn:aws:lex:*:*:bot/*",
                "arn:aws:lex:*:*:bot-alias/*"
            ]
        }
    ]            
}

You can restrict permissions further by modifying them as follows.

  • Replace * with specific bot or bot alias IDs to limit the permissions to specific bots or bot aliases.

  • Use a subset of the lex BotReplica actions to restrict the role to specific actions.

For an example, see Allow users to create and view bot replicas, but not to delete them.
