Retrieves the properties of the requested container. This request is commonly used to retrieve the endpoint of a container. An endpoint is a value assigned by the service when a new container is created. A container's endpoint does not change after it has been assigned. The <code>DescribeContainer</code> request returns a single <code>Container</code> object based on <code>ContainerName</code>. To return all <code>Container</code> objects that are associated with a specified AWS account, use <a>ListContainers</a>.
