Updating an AWS Cloud Map service

Sign in to the AWS Management Console and open the AWS Cloud Map console at https://console.aws.amazon.com/cloudmap/.

In the navigation pane, choose Namespaces.

On the Namespaces page, choose the namespace in which the service is created.

On the Namespace: namespace-name page, select the service you want to edit and choose View details.

On the Service: service-name page, choose Edit.

On the Edit service page, under Service description, you can update any previously set description for the service or add a new description. You can also add tags and update TTL for DNS resolvers.

Under DNS configuration, for TTL, you can specify an updated period of time, in seconds, that determines how long DNS resolvers cache information for this record before the resolvers forward another DNS query to Amazon Route 53 to get updated settings.

If you've set up Route 53 health checks, for Failure threshold, you can specify a new number between 1 and 10 that defines the number of consecutive Route 53 health checks a service instance must pass or fail for its health status to change.

Choose Update service.

If you don't already have Boto3 installed, you can find instructions for installing, configuring, and using Boto3 here.

Import Boto3 and use servicediscovery as your service.

import boto3
client = boto3.client('servicediscovery')

Update a service with update_service() (replace the red value with your own).

response = client.update_service(
    Id='srv-xxxxxxxxxxx',
    Service={
        'DnsConfig': {
            'DnsRecords': [
                {
                    'TTL': 300,
                    'Type': 'A',
                },
            ],
        },
        'Description': "new description",
    }
)
