I am trying to deploy Kibana from the Helm chart via an App in Rancher 2.2.8.  
I want to mount in a CA certificate file for our internal CA authority, so I created a ConfigMap called `elasticsearch-ca`.

The Kibana chart description has the following to allow you to mount additional ConfigMaps:

```auto
Parameter Description Default
extraConfigMapMounts Additional configmaps to be mounted []

```

I don’t know what to put as the value for this in the Answers section. I have tried several formats:

```auto
['elasticsearch-ca']
[elasticsearch-ca]
"[elasticsearch-ca]"
["elasticsearch-ca"]
"elasticsearch-ca"

```

When I click on the app, it shows the following error (with whatever I put as the answer):

`Wait helm template failed. Error: render error in "kibana/templates/deployment.yaml": template: kibana/templates/deployment.yaml:194:17: executing "kibana/templates/deployment.yaml" at <.Values.extraConfigM...>: range can't iterate over "elasticsearch-ca" : exit status 1`

Hey!  
For those guys and girls who came from google search:  
You need to switch to YML editor and type something like that:

> ```
> ingress: 
> hosts:
> - host: example.domain.ltd
> 
> ```

It is equivalent for:

> ```
> Parameter Description Default
> ingress.hosts Ingress accepted hosts []
> 
> ```

Hi guys,  
I think this is the answer what is being looked for:

In Terraform:

> set {  
> name = “extraConfigMapMounts[0]”  
> value = “elasticsearch-ca”  
> }

With command line usage:

> helm install mychart --set extraConfigMapMounts[0]=elasticsearch-ca

In terms of Helm it will create k8s resource in the YML format which was mentioned by @beshkenadze
