HAProxy has been has been successfully installed. This Chart is used to run HAProxy as a regular application,
as opposed to HAProxy Ingress Controller Chart.

Controller image deployed is: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}".
Your HAProxy app is of a "{{ .Values.kind }}" kind.

Service ports mapped are:
{{- $nodePorts := .Values.service.nodePorts }}
{{- $servicePortType := .Values.service.type }}
{{- if eq .Values.kind "Deployment" }}
{{- range $key, $value := .Values.containerPorts }}
  - name: {{ $key }}
    containerPort: {{ $value }}
    protocol: TCP
    {{- if and (hasKey $nodePorts $key) (eq $servicePortType "NodePort") }}
    nodePort: {{ get $nodePorts $key }}
    {{- end }}
{{- end }}
{{- end }}
{{- if eq .Values.kind "DaemonSet" }}
{{- $hostPorts := .Values.daemonset.hostPorts -}}
{{- $useHostPort := .Values.daemonset.useHostPort -}}
{{- range $key, $value := .Values.containerPorts }}
  - name: {{ $key }}
    containerPort: {{ $value }}
    protocol: TCP
    {{- if $useHostPort }}
    hostPort: {{ index $hostPorts $key | default $value }}
    {{- end }}
    {{- if and (hasKey $nodePorts $key) (eq $servicePortType "NodePort") }}
    nodePort: {{ get $nodePorts $key }}
    {{- end }}
{{- end }}
{{- end }}

To be able to bind to privileged ports as non-root, the following is required:

securityContext:
  enabled: true
  runAsUser: 1000
  runAsGroup: 1000
initContainers:
  - name: sysctl
    image: "busybox:musl"
    command:
      - /bin/sh
      - -c
      - sysctl -w net.ipv4.ip_unprivileged_port_start=0
    securityContext:
      privileged: true

Node IP can be found with:
  $ kubectl --namespace {{ template "haproxy.namespace" . }} get nodes -o jsonpath="{.items[0].status.addresses[1].address}"
