Helm values with annotations for fixed IPs/IDs

[baptiste-gaillet]

To deploy Otoroshi using Helm and GitOps, it is recommended to fix the IP addresses and provide these fixed values ​​to the deployment.

With Scaleway, you can add annotations for this purpose.

A possible example for this feature request.

Add in the helm values :

  # Fixed IPs for Leader and Worker
  # Allowed values: null or (leaderIP or scaleway leaderIPId)
  leaderIP: null
  leaderIPId: "478baa34-5bcf-438e-a72e-5a422bc46a50"
  workerIP: null
  workerIPId: "4b4fd006-7024-4e95-8024-c038ac086cae"

Add in the cluster/deploy template:

---
apiVersion: v1
kind: Service
metadata:
  name: {{ .Values.cluster.leaderExternalServiceName }}
  namespace: {{ .Release.Namespace }}
  labels:
    {{- include "otoroshi.labels" . | nindent 4 }}
    app.kubernetes.io/component: leader
  {{- if or .Values.loadbalancer.annotations .Values.loadbalancer.leaderIPId }}
  annotations:
    {{- with .Values.loadbalancer.annotations }}
    {{- toYaml . | nindent 4 }}
    {{- end }}
    {{- if .Values.loadbalancer.leaderIPId }}
    service.beta.kubernetes.io/scw-loadbalancer-ip-ids: {{ .Values.loadbalancer.leaderIPId | quote }}
    {{- end }}
  {{- end }}
spec:
  type: {{ $lbType }}
  {{- if and (eq $lbType "LoadBalancer") .Values.loadbalancer.leaderIP }}
  loadBalancerIP: {{ .Values.loadbalancer.leaderIP | quote }}
  {{- end }}
  {{- if eq $lbType "LoadBalancer" }}
  {{- if .Values.loadbalancer.loadBalancerClass }}
  loadBalancerClass: {{ .Values.loadbalancer.loadBalancerClass | quote }}
  {{- end }}
  {{- with .Values.loadbalancer.sourceRanges }}
  loadBalancerSourceRanges:
    {{- toYaml . | nindent 4 }}
  {{- end }}
  {{- end }}
  selector:
    {{- include "otoroshi.selectorLabels" . | nindent 4 }}
    app.kubernetes.io/component: leader
  ports:
  - port: {{ .Values.loadbalancer.http }}
    name: "http"
    targetPort: "http"
    {{- if eq $lbType "NodePort" }}
    nodePort: {{ .Values.loadbalancer.nodePort.http }}
    {{- end }}
  - port: {{ .Values.loadbalancer.https }}
    name: "https"
    targetPort: "https"
    {{- if eq $lbType "NodePort" }}
    nodePort: {{ .Values.loadbalancer.nodePort.https }}
    {{- end }}
---
apiVersion: v1
kind: Service
metadata:
  name: {{ .Values.cluster.workerExternalServiceName }}
  namespace: {{ .Release.Namespace }}
  labels:
    {{- include "otoroshi.labels" . | nindent 4 }}
    app.kubernetes.io/component: worker
  {{- if or .Values.loadbalancer.annotations .Values.loadbalancer.workerIPId }}
  annotations:
    {{- with .Values.loadbalancer.annotations }}
    {{- toYaml . | nindent 4 }}
    {{- end }}
    {{- if .Values.loadbalancer.workerIPId }}
    service.beta.kubernetes.io/scw-loadbalancer-ip-ids: {{ .Values.loadbalancer.workerIPId | quote }}
    {{- end }}
  {{- end }}
spec:
  type: {{ $lbType }}
  {{- if and (eq $lbType "LoadBalancer") .Values.loadbalancer.workerIP }}
  loadBalancerIP: {{ .Values.loadbalancer.workerIP | quote }}
  {{- end }}
  {{- if eq $lbType "LoadBalancer" }}
  {{- if .Values.loadbalancer.loadBalancerClass }}
  loadBalancerClass: {{ .Values.loadbalancer.loadBalancerClass | quote }}
  {{- end }}
  {{- with .Values.loadbalancer.sourceRanges }}
  loadBalancerSourceRanges:
    {{- toYaml . | nindent 4 }}
  {{- end }}
  {{- end }}
  selector:
    {{- include "otoroshi.selectorLabels" . | nindent 4 }}
    app.kubernetes.io/component: worker
  ports:
  - port: {{ .Values.loadbalancer.http }}
    name: "http"
    targetPort: "http"
    {{- if eq $lbType "NodePort" }}
    nodePort: {{ .Values.loadbalancer.nodePort.http }}
    {{- end }}
  - port: {{ .Values.loadbalancer.https }}
    name: "https"
    targetPort: "https"
    {{- if eq $lbType "NodePort" }}
    nodePort: {{ .Values.loadbalancer.nodePort.https }}
    {{- end }}
{{- end }}

This template add the possibility for ID-IPs and IPs, but only ID-IPs on scaleway was tested and works well.

Thx ;p
