How can I uniquely ID the AWS Lambda container that my function is running in?

问题

I would like to get the (AWS Lambda container) instance ID that my function is running in.

For now I would just log it - it would help me when debugging issues with my caching algorithm: I could identify which invocations were happening in the same instance.

I looked at the docs for the context object and don't see anything there.

I could do it manually - and I'll put that below as my fallback answer - but I thought I would check whether some sort of real instance ID is available somehow.

回答1:

Could just generate a random GUID save that in global. (I'm just starting to look at this issue of container re-use and the potential for data caching, but I assume that node's 'global' object remains intact when an instance is re-used.)
