Helm charts nested loops

I think you should reconsider the way the data is structured, this would work better:

  services:  - name: backend    settings:      port: 80      targetPort: 8080      replicaCount: 1      environmentVariables:        - name: SOME_VAR          value: "hello"  - name: web    settings:      port: 80      targetPort: 8080      replicaCount: 1      environmentVariables:        - name: SOME_VAR          value: "hello"

And your Deployment to look like this:

{{- range .Values.services }}---apiVersion: apps/v1beta1kind: Deploymentmetadata:  name: myapp-{{ .name }}spec:  replicas: {{ .settings.replicaCount }}  template:    metadata:      labels:        app: myapp-{{ .name }}    spec:      containers:      - name: myapp-{{ .name }}        image: {{ $.Values.containerRegistry }}/myapp-{{ .name }}:latest        ports:        - containerPort: {{ .settings.targetPort }}        env:  {{- with .settings.environmentVariables }}  {{ toYaml . | trim | indent 6 }}  {{- end }}      imagePullSecrets:       - name: myregistry{{- end }}

would actually create two deployments, by adding the --- separator.
