This ID is passed as part of the container contract and used for all portable API calls from that container. I think it's desirable that it's a single ID for simplicity and debuggability. Python's use of an environment variable to pass it around is an implementation detail and not, for example, how the Go SDK does it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
