helm chart conditional install based on a list - kubernetes

Question

I'm trying to find a way to optionally install a manifest based on a list or a map (really don't mind which) in the values file.
in the values file I have
provisioners: ["gp","test"]
and in the manifest I have
{{- if has "test" .Values.provisioners }}
I've also tried
provisioners:
- "gp"
- "test"
and put this in the yaml
{{- if hasKey .Values.provisioners "test" }}
but I can't either way to work, the chart never installs anything.
I feel like I'm missing something pretty basic, but I can't figure out what. Can someone point me in the right direction.

Answer 1

I don't think you shared everything in you template and there might be something else. What you already did is correct, as you in my example below:
# templates/configmap.yaml
{{- if has "test" .Values.provisioners }}
---
apiVersion: v1
kind: ConfigMap
metadata:
name: test-config
namespace: default
data:
config.yaml: |
attr=content
{{- end }}
{{- if has "gp" .Values.provisioners }}
---
apiVersion: v1
kind: ConfigMap
metadata:
name: gp-config
namespace: default
data:
config.yaml: |
attr=content
{{- end }}
{{- if has "unknown" .Values.provisioners }}
---
apiVersion: v1
kind: ConfigMap
metadata:
name: not-templated-config
namespace: default
data:
config.yaml: |
attr=content
{{- end }}
Output of the helm template . against local chart:
---
# Source: chart/templates/configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: test-config
namespace: default
data:
config.yaml: |
attr=content
---
# Source: chart/templates/configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: gp-config
namespace: default
data:
config.yaml: |
attr=content
