Minikube: Exposing REST API from Docker container - docker

Question

I currently have a Dockerised Spring Boot application with exposed Java REST APIs that I deploy on to my NUC (just a remote machine) and can connect to it from my Mac, via the NUCs static IP address. Both machines are on the same network.
I am now looking into hosting the Docker application in Kubernetes (Minikube)
(using this tutorial https://medium.com/bb-tutorials-and-thoughts/how-to-run-java-rest-api-on-minikube-4b564ea982cc).
I have used the Kompose tool from Kubernetes to convert my Docker compose files into Kubernetes deployments and services files. One of the services I'm trying to get working first simply opens up port 8080 and has a number of REST resources. Everything seems to be up and running, but I cannot access the REST resources from my Mac (or even the NUC itself) with a curl -v command.
After getting around a small issue with my Docker images (needing built to Minikube's internal Docker images repo), I can successfully deploy my services and deployments. There are a number of others, but for the purposes of getting past this step, I'll just include the one:
$ kubectl get po -A
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system coredns-f9fd979d6-hhgn8 1/1 Running 0 7h
kube-system etcd-minikube 1/1 Running 0 7h

meanwhileinhell apigw-75bc5z1f5j-cklxt 1/1 Running 0 6h54m
$ kubectl get service apigw
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
apigw NodePort 10.107.116.239 <none> 8080:32327/TCP 6h53m
$ kubectl cluster-info
Kubernetes master is running at https://192.168.44.2:8443
KubeDNS is running at https://192.168.44.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
However, I cannot hit this master IP address, or any expected open port using the static IP of my NUC. I have tried to use the service types LoadBalancer and NodePort for the service but the former hangs on pending for the external IP.
I have played about a little with exposing ports and port forwarding but haven't been able to get anything working (port 7000 is just an arbitrary number):
kubectl port-forward apigw 7000:8080
kubectl expose deployment apigw --port=8080 --target-port=8080
Here is my apigw deployment, service and pod yaml files:

Using kubectl create -f to create the services.
