set-standard-labels: Deployment Example

Overview

This example demonstrates how to add kubernetes recommended labels to kpt Deployment packages by running the [set-starndard-labels] function.

Fetch the example package

Get the example package by running the following commands:

$ kpt pkg get https://github.com/GoogleContainerTools/kpt-functions-catalog.git/examples/set-stanrdard-labels-deployment

We use the following Kptfile to configure the function.

apiVersion: kpt.dev/v1
kind: Kptfile
metadata:
  name: frontend
  annotations:
    config.kubernetes.io/local-config: "true"

Function invocation

Invoke the function by running the following commands:

$ kpt fn render set-stanrdard-labels-deployment

Expected result

Check the deployment has label app.kubernetes.io/instance: frontend-dev added, and the existing upstream label app.kubernetes.io/name: frontend is preserved.
