Configure Amazon SNS topics for notifications - Developer Tools console

Configure Amazon SNS topics for notifications

The easiest way to set up notifications is to create an Amazon SNS topic when you create a notification rule. You can use an existing Amazon SNS topic if it meets the following requirements:

  • It was created in the same AWS Region as the resource (build project, deployment application, repository, or pipeline) for which you want to create notification rules.

  • It has not been used for sending notifications for CodeCommit before November 5, 2019. If it has, it will contain policy statements that enabled that functionality. You can choose to use this topic, but you will need to add the additional policy as specified in the procedure. You should not remove the existing policy statement if one or more repositories is still configured for notifications before November 5, 2019.

  • It has a policy that allows AWS CodeStar Notifications to publish notifications to the topic.

To configure an Amazon SNS topic to use as a target for AWS CodeStar Notifications notification rules

  1. Sign in to the AWS Management Console and open the Amazon SNS console at https://console.aws.amazon.com/sns/v3/home.

  2. In the navigation bar, choose Topics, choose the topic you want to configure, and then choose Edit.

  3. Expand Access policy, and then choose Advanced.

  4. In the JSON editor, add the following statement to the policy. Include the topic ARN, AWS Region, AWS account ID, and topic name.

    	{
      "Sid": "AWSCodeStarNotifications_publish",
      "Effect": "Allow",
      "Principal": {
        "Service": [
          "codestar-notifications.amazonaws.com"
        ]
      },
      "Action": "SNS:Publish",
      "Resource": "arn:aws:sns:us-east-2:123456789012:codestar-notifications-MyTopicForNotificationRules"
    }

    The policy statement should look like the following.

    {
  "Version": "2008-10-17",
  "Id": "__default_policy_ID",
  "Statement": [
    {
      "Sid": "__default_statement_ID",
      "Effect": "Allow",
      "Principal": {
        "AWS": "*"
      },
      "Action": [
        "SNS:GetTopicAttributes",
        "SNS:SetTopicAttributes",
        "SNS:AddPermission",
        "SNS:RemovePermission",
        "SNS:DeleteTopic",
        "SNS:Subscribe",
        "SNS:ListSubscriptionsByTopic",
        "SNS:Publish"
      ],
      "Resource": "arn:aws:sns:us-east-2:123456789012:codestar-notifications-MyTopicForNotificationRules",
      "Condition": {
        "StringEquals": {
          "AWS:SourceOwner": "123456789012"
        }
      }
    },
	{
      "Sid": "AWSCodeStarNotifications_publish",
      "Effect": "Allow",
      "Principal": {
        "Service": [
          "codestar-notifications.amazonaws.com"
        ]
      },
      "Action": "SNS:Publish",
      "Resource": "arn:aws:sns:us-east-2:123456789012:codestar-notifications-MyTopicForNotificationRules"
    }
  ]
}

  5. Choose Save changes.

  6. If you want to use an AWS KMS-encrypted Amazon SNS topic to send notifications, you must also enable compatibility between the event source (AWS CodeStar Notifications) and the encrypted topic by adding the following statement to the policy of the AWS KMS key. Replace the AWS Region (in this example, us-east-2) with the AWS Region where the key was created.

    {
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "codestar-notifications.amazonaws.com"
            },
            "Action": [
                "kms:GenerateDataKey*",
                "kms:Decrypt"
            ],
            "Resource": "*",
            "Condition": {
                "StringEquals": {
                    "kms:ViaService": "sns.us-east-2.amazonaws.com"
                }
            }
        }
    ]
}
