2019-10-26 08:05:57 UTC - Rodric Rabbah: We don’t have a particular technical write up on this. The short of it is this: every activation assignment is tracked in the load balancer to get a sense of the high water mark per invoker. Requests are assigned to an invoker by computing the set of allowed Invokers for a request and then picking the lowest loaded invoker. If none are found pick the home invoker. Every request has a hash that computes it’s canonical home.
The heuristic is to provide elasticity and promote reuse.

2019-10-26 16:39:16 UTC - Ali Tariq: just to be clear, you have a serverless action that takes an input parameter. When you invoke is using wsk cli with commandline argument - it works fine, but when i try to invoke it using api url, it returns the error.

Run wsk activation list
Run it twice just to be sure you have the most recent time stamp
Confirm the time stamp matches your curl
And look at the error for the failed activation id by doing wsk activation get

2019-10-26 23:14:47 UTC - Krzysztof Sobkowiak: I have installed OpenWhisk on Minikube using openwhisk-deploy-kube. The inactive action pods are destroyed after 10 minutes. I'd like to configure OpenWhisk to destroy the pods after 1 minute (for a demo). Which parameters should I set to change the pod termination time?
