Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Retrieving configuration data for applications running in Amazon ECS and Amazon EKS

You can retrieve configuration data from Amazon AppConfig Agent for applications running in Amazon ECS and Amazon EKS by using an HTTP localhost call. The following examples use curl with an HTTP client. You can call the agent using any available HTTP client supported by your application language or available libraries.

Note

To retrieve configuration data if your application uses a forward slash, for example "test-backend/test-service", you will need to use URL encoding.

To retrieve the full content of any deployed configuration

$ curl "http://localhost:2772/applications/application_name/environments/environment_name/configurations/configuration_name"

To retrieve a single flag and its attributes from an Amazon AppConfig configuration of type Feature Flag

$ curl "http://localhost:2772/applications/application_name/environments/environment_name/configurations/configuration_name?flag=flag_name"

To access multiple flags and their attributes from an Amazon AppConfig configuration of type Feature Flag


$ curl "http://localhost:2772/applications/application_name/environments/environment_name/configurations/configuration_name?flag=flag_name_one&flag=flag_name_two"

The call returns configuration metadata in HTTP headers, including the configuration version, content type, and configuration version label (if applicable). The body of the agent response contains the configuration content. Here is an example:


HTTP/1.1 200 OK
Configuration-Version: 1
Content-Type: application/json
Date: Tue, 18 Feb 2025 20:20:16 GMT
Content-Length: 31
