Amazon ECS task metadata endpoint

Amazon ECS on Fargate provides a method to retrieve various metadata, network metrics, and Docker stats about your tasks and containers. This is referred to as the task metadata endpoint. The following task metadata endpoint versions are available for Fargate tasks:

  • Task metadata endpoint version 4 – Available for tasks that use the Fargate launch type on platform version 1.4.0 or later.

  • Task metadata endpoint version 3 – Available for tasks that use the Fargate launch type on platform version 1.1.0 or later.

All containers belonging to tasks that are launched with the awsvpc network mode receive a local IPv4 address within a predefined link-local address range. When a container queries the metadata endpoint, the container agent can determine which task the container belongs to based on its unique IP address, and metadata and stats for that task are returned.
