NGINX Ingress + local DNS

• configure kubeadmConfigPatches by example above

• configure nginx ingress controller

ingress-nginx:
  controller:
    image:
      runAsNonRoot: true
      readOnlyRootFilesystem: false
      allowPrivilegeEscalation: false
      seccompProfile:
        type: RuntimeDefault
    extraArgs:
      publish-status-address: localhost
    service:
      type: NodePort
    hostPort:
      enabled: true
    publishService:
      enabled: false
    updateStrategy:
      type: RollingUpdate
      rollingUpdate:
        maxUnavailable: 1
    terminationGracePeriodSeconds: 0
    nodeSelector:
      ingress-ready: "true"
    tolerations:
      - effect: NoSchedule
        key: node-role.kubernetes.io/master
        operator: Equal
      - effect: NoSchedule
        key: node-role.kubernetes.io/control-plane
        operator: Equal
    allowSnippetAnnotations: false
    watchIngressWithoutClass: true
    metrics:
      enabled: true
      serviceMonitor:
        enabled: true

• for each ingress host add appropriate record to /etc/hosts file

cat /etc/hosts
##

# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
