Conditional Rendering of Individual Resources

In this example, we show how each resource in a pipeline step can be individually rendered based on a condition. We will have a blue and a green deployment that the user can activate:

apiVersion: nop.example.org/v1alpha1
kind: XNopConditional
metadata:
  name: test-resource
spec:
  env: dev
  render: true
  deployment:
    blue: true
    green: false

In our Composition both the blue-resource and the green-resource have a condition that determines if they will be run.

    resources:
         - name: blue-resource
           condition: observed.composite.resource.spec.deployment.blue == true
           base:
            apiVersion: nop.crossplane.io/v1alpha1
            kind: NopResource
            spec:
              forProvider:

Running this example

• Install Crossplane version 1.14 or newer. See https://docs.crossplane.io/v1.14/software/install/
• Install the nop provider in kubectl apply -f provider.yaml
• Install the XRD & Composition in kubectl apply -f definition.yaml -f composition.yaml
• Install the Function kubectl apply -f functions.yaml

Finally install the xr: kubectl apply -f xr
