Helm value overrides

[antwacky]

Referencing this issue which was closed without resolution, how can I override Helm chart values per environment?

For example... The below should(?) work, but doesn't.

The lib has the controller set to deployment by default:

# lib/system.libsonnet

local new() =
  {

    local helm = tanka.helm.new(std.thisFile),
    local helmChartsPath = '../../../helm/charts/',

    apps:: {

      // Third Party Dependencies

      ingressController: {
        values:: {
          "ingress-nginx": {
            controller: {
              kind: "Deployment"
            }
          }
        },
        app: helm.template('ingress-nginx', std.format('%s/ingress-controller', helmChartsPath), {
          namespace: 'kube-system',
          values: $.apps.ingressController.values,
        }),
        dependencies: [],
      }
  }

The local environment should have the controller kind set to daemonset:

# environments/local/main.jsonnet

local system = (import 'system.libsonnet');

{
  _: std.mergePatch(system.new(), {
    apps: {
      ingressController: {
        values:: {
          "ingress-nginx": {
            controller: {
              kind: "Daemonset"
            },
          },
        },
      },
    },
  }),
}

It actually works exactly as expected, the error was I specified Daemonset rather than DaemonSet.

The other problem is that apps: is a hidden field, so that becomes apps::.
