In my values config file, I have an array of dictionaries as follows:
connects_to
- name: myname
release: optional release
- name: another name
Note that name will always be provided but release may or may not be. In my template, I have:
{{- if .Values.connects_to }}
app.openshift.io/connects-to: '
{{- range .Values.connects_to -}}
{{- if .release -}}
{{- .release -}}-{{- .name -}},
{{- else -}}
{{- $.Release.Name -}}-{{- .name -}},
{{- end -}}
{{- end -}}
'
{{- end }}
which gives the error:
can't evaluate field release in type interface {}
I have also tried using "hasKey" as follows:
{{- if .Values.connects_to }}
app.openshift.io/connects-to: '
{{- range .Values.connects_to -}}
{{- if hasKey . "release" -}}
{{- .release -}}-{{- .name -}},
{{- else -}}
{{- $.Release.Name -}}-{{- .name -}},
{{- end -}}
{{- end -}}
'
{{- end }}
which gives the error:
wrong type for value; expected map[string]interface {}; got string
How would I accomplish this check without having to specify a value for "release" every time? My helm version:
version.BuildInfo{Version:"v3.2.3+4.el8", GitCommit:"2160a65177049990d1b76efc67cb1a9fd21909b1", GitTreeState:"clean", GoVersion:"go1.13.4"}
This actually works with the "hasKey" approach, there was an error in the values definition.
