set-namespace: Simple Example #

Overview #

This example demonstrates how to run set-namespace function to replace the namespace resource type in a variety of KRM resources.

Fetch the example package #

Get the example package by running the following commands:

$ kpt pkg get https://github.com/kptdev/krm-functions-catalog.git/examples/set-namespace-simple

We use the following Kptfile to configure the function.

apiVersion: kpt.dev/v1
kind: Kptfile
metadata:
  name: example
pipeline:
  mutators:
    - image: ghcr.io/kptdev/krm-functions-catalog/set-namespace:latest
      configMap:
        namespace: example-ns

The function configuration is provided using a ConfigMap. We set only one key-value pair:

• namespace: example-ns: The desired namespace.

Function invocation #

Invoke the function by running the following commands:

$ kpt fn render set-namespace-simple

Expected result #

Check all resources have metadata.namespace set to example-ns
