AWS::ECS::Service ServiceConnectClientAlias - AWS CloudFormation

AWS::ECS::Service ServiceConnectClientAlias

Each alias ("endpoint") is a fully-qualified name and port number that other tasks ("clients") can use to connect to this service.

Each name and port mapping must be unique within the namespace.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{ "DnsName" : String, "Port" : Integer }

YAML

DnsName: String Port: Integer

Properties

DnsName

The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace.

To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database, db, or the lowercase name of a database, such as mysql or redis. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide.
