Openwhisk: only 8 concurrent containers running at a time
I deployment the Openwhisk locally in an EC2 VM Instance with docker Compose, in terms of the docs "How to setup OpenWhisk with Docker Compose"
My VM has 4 vCPU / 8GB MEM
but I can only start 8 concurrent containers running at a time!!!
how can I increase it?

The default deployment configuration sets the invoker_user_memory (the amount of memory available to run user actions) to 2GB (https://github.com/apache/incubator-openwhisk/blob/master/ansible/group_vars/all#L192). The default memory for a node action is 256MB. So that's where the limit of 8 concurrent containers you are seeing is coming from (2048/256 = 8).
If you change invoker_user_memory when you deploy your OpenWhisk instance, you can configure it to enable more concurrent actions.
