When I deploy the following I get this error:

{{- $fullName := include "marketplace.fullname" . -}}

{{- end }}
Error:
Error: UPGRADE FAILED: render error in "marketplace/templates/front-ingress.yaml": template: marketplace/templates/front-ingress.yaml:36:30: executing "marketplace/templates/front-ingress.yaml" at <include "marketplace...>: error calling include: template: marketplace/templates/_helpers.tpl:6:18: executing "marketplace.name" at <.Chart.Name>: can't evaluate field Chart in type string
marketplace.name
is defined in _helpers.tpl:
{{- define "marketplace.name" -}}
{{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" -}}
{{- end -}}
.Chart.Name
is an internal variable and the order of preference is explained here but even setting nameOverride
the error is the same.
The strange thing is if I remove this template, .Chart.Name
works fine within any other template so I think the problem is related to the scopes of the range
used.
Values used:
front:
ingress:
enabled: true
annotations:
kubernetes.io/ingress.class: nginx-int
nginx.ingress.kubernetes.io/rewrite-target: /
nginx.ingress.kubernetes.io/force-ssl-redirect: "false"

Please see related issue.
Based on this workaround, you can store .
in a variable, since inside of range
loop, .
refers to actual value of paths:
Also you may want to replace - path: /
with - path: {{ . }}
{{- if .Values.front.ingress.enabled -}}
{{- $fullName := include "bchart.fullname" . -}}
{{- $ingressPaths := .Values.front.ingress.paths -}}
{{- $dot := . }}

- path: {{ . }}

serviceName: {{ include "bchart.name" $dot }}-{{ $.Values.front.name }}
