How can an ECS task know in which region is runs?

问题

I have a python application using boto3 in a task launched by ECS (in a docker container). The boto3 command I use need a region to work properly, but I only know the region at runtime (multi-region application). The idea was then to define the AWS_DEFAULT_REGION environment variable by retrieving the region in the dynamic document provided by Amazon from URI http://169.254.169.254. However, whereas the call works fine from the instance, I cannot access the endpoint from within the task container.

Is there a clean way to know in which region the task actually runs ?
