Names of helm chart created resources

[lkiii]

Hi,

I have a case where I have some helm installed resources already in the cluster and I want to migrate them to my tanka project.

The issue I am facing is that now all the resources are names same way as a chart, but using tanka - naming convention by default is name + chart_name

For example:

local tanka = import 'github.com/grafana/jsonnet-libs/tanka-util/main.libsonnet';
local helm = tanka.helm.new(std.thisFile);
local k = import 'k.libsonnet';

{
  namespace: k.core.v1.namespace.new('ns'),
  chart: helm.template('name', '../../charts/chart-name, {
    namespace: 'ns',
    values: { },
  }),
}

And my resource in the cluster current name is just chart-name but if I am doing tk diff - I am getting all the names as name-chart-name

I have tried passing empty string as name chart: helm.template('', '../../charts/chart-name, {, but that gives me an error as name needs to be not empty.

There is also nameFormat param for the helm.template but as I have understood it is not for resource names, but for json key names?

What are my options with this issue?

I am trying to understand options for the params for helm.template(). I believe it is this one https://github.com/grafana/tanka/blob/main/pkg/helm/jsonnet.go#L39?

Digging deeper I realised that tanka does not do anything there as it just calls helm template with what you pass as the arguments. In general this is specific helm chart internal details which resulted this behaviour.
