Cannot deploy basic OpenWhisk action onto Kubernetes running with Minikube – Nginx

I am trying to setup a simple POC of Apache OpenWhisk serverless framework running on Kubernetes. I am using MacOS with Minikube. Here are the specs:

Kubernetes: v1.20.2
Minikube: v1.17.0
Docker: 20.10.0-rc1, 4.26GB allocated

Here are the setup steps for Minikube:

$ minikube start --cpus 2 --memory 4096 --kubernetes-version=v1.20.2
$ minikube ssh -- sudo ip link set docker0 promisc on
$ kubectl create namespace openwhisk
$ kubectl label nodes --all openwhisk-role=invoker

Install OpenWhisk using Helm:

$ helm install owdev ./helm/openwhisk -n openwhisk --create-namespace -f mycluster.yaml

Configure Whisk CLI:

$ wsk property set --apihost 192.168.49.2:31001
$ wsk property set --auth 23bc46b1-71f6-4ed5-8c54-816aa4f8c502:123zO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP

The 192.168.49.2 IP address of Minikube was confirmed by typing:

$ minikube ip

Here is my mycluster.yaml file:

whisk:
  ingress:
    type: NodePort
    apiHostName: 192.168.49.2
    apiHostPort: 31001

nginx:
  httpsNodePort: 31001

I checked the health of my OpenWhisk setup:

$ kubectl get pods -n openwhisk

Finally, I created a simple hello world action following these instructions taken directly from the OpenWhisk documentation. When I try to test the action, I get a network timeout:

$ wsk action create helloJS hello.js

error: Unable to create action ‘helloJS’: Put "https://192.168.49.2:31001/api/v1/namespaces/_/actions/helloJS?overwrite=false": dial tcp 192.168.49.2:31001: i/o timeout

I tried turning on debug mode with the -d switch, but could not make much of what feedback I am seeing.

My feeling is that there is either a bug at work here, or perhaps Minikube on Mac was never intended to be fully supported on OpenWhisk.

Can anyone suggest what I might try to get this setup and action working?
