NGINX Pkl Chart

This is a re-implementation of the nginx helm chart in Pkl. It provides the same functionality as the base chart but via pkl.

Usage

To apply the chart directly, use this command.

pkl chart.pkl | kubectl apply -f -

Extend and configure

Create a PklProject file

amends "pkl:Project"

dependencies {
  ["k8s"] {
    uri = "package://pkg.pkl-lang.org/pkl-k8s/[email protected]"
  }
  ["chart"] {
    uri = "package://github.com/MarkSRobinson/nginx-pkl/releases/download/1.0.0/@1.0.0"
  }
}

Create your own chart.pkl

amends "@chart/chart.pkl"

chart {
  services {
    default {
      metadata {
        labels {
          ["help"] ="I'm stuck in a yaml factory"
        }
      }
    }
  }
}

Apply

pkl chart.pkl | kubectl apply -f -
