How to run kubernetes-sigs/kind with ingress and some service on dev machine?

Question

Kubernetes

https://github.com/kubernetes-sigs/kind - version 0.4.0
Create kubernetes from kubernetes-sigs/kind
Create kind-example-config.yaml file

kind: Cluster
apiVersion: kind.sigs.k8s.io/v1alpha3
nodes:
- role: control-plane
- role: worker
  extraPortMappings:
  - containerPort: 80
    hostPort: 80
    listenAddress: "192.168.0.9" # Адрес сетевой карты

kind create cluster --config kind-example-config.yaml

Creating cluster "kind" ...
     ✓ Ensuring node image (kindest/node:v1.15.0)

kubectl create serviceaccount --namespace kube-system tiller
serviceaccount/tiller created
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller

clusterrolebinding.rbac.authorization.k8s.io/tiller-cluster-rule created

helm init --service-account tiller
I installed metallb - but it didn't work in the end.

kubectl apply -f https://raw.githubusercontent.com/google/metallb/v0.7.3/manifests/metallb.yaml
namespace/metallb-system created
serviceaccount/controller created
serviceaccount/speaker created
clusterrole.rbac.authorization.k8s.io/metallb-system:controller created
clusterrole.rbac.authorization.k8s.io/metallb-system:speaker created
role.rbac.authorization.k8s.io/config-watcher created
clusterrolebinding.rbac.authorization.k8s.io/metallb-system:controller created
clusterrolebinding.rbac.authorization.k8s.io/metallb-system:speaker created
rolebinding.rbac.authorization.k8s.io/config-watcher created
daemonset.apps/speaker created
deployment.apps/controller created

Checked pod status

kubectl get pod --namespace=metallb-system

vi metallb-config.yaml

kubectl apply -f metallb-config.yaml
helm install stable/nginx-ingress

I need to test including ingress.
NodePort, Minikube, port-forward are not offered.

Answer 1

Here is an example
https://jsfiddle.net/yarkov_aleksei/v2tuxeyb/1/

const groups = [
  { id: 1, name: 'group 1', items_ids: [1, 2, 4] },
  { id: 2, name: 'group 2', items_ids: [8, 2, 3] },
  { id: 3, name: 'group 3', items_ids: [12, 1] },
  { id: 4, name: 'group 4', items_ids: [] },
  { id: 5, name: 'group 5', items_ids: [] },
]

const result = groups
  .filter(group => group.items_ids.length > 0)
  .reduce((prev, next, i, acc) => prev.concat(next.items_ids), [])

console.clear()
console.log(result) // [1, 2, 4, 8, 2, 3, 12, 1]
console.log([...new Set(result)]) // [1, 2, 4, 8, 3, 12]
