How to remove Kamelets installation when installing IntegrationPlatform CRD?

[zhiminglim]

Hello,

I'm working with Camel K with Helm, and instead of doing the traditional kamel run I'm deploying it via a helm chart, hence I have to write the CRDs.

As I have to work with deploying the same integrations in multiple namespaces, I have to set up an IntegrationPlatform per namespace via a YAML file.

---
apiVersion: camel.apache.org/v1
kind: IntegrationPlatform
metadata:
  name: camel-k
  labels:
    {{ include "chart.labels" . | nindent 4 }}
  namespace: {{ .Release.namespace }} 
spec:
  build:
    maven:
      settings:
        secretKeyRef:
          key: settings.xml
          name: camel-k-maven-settings
    registry:
      address: xxx.acr.io
      secret: camel-k-registry-secret
    timeout: 30m0s

As I apply the above manifest into Kubernetes, the Camel K Operator also installs Kamelets into each namespace. But when i uninstall the helm chart, the Kamelets are still left in the namespace intact. Is there a way to disable the creation of Kamelets when working directly with the IntegrationPlatform CRD so that I won't have leftover Kamelets CRDs (and also CamelCatalogs) in the namespace when I no longer wish to use the IntegrationPlatform/Integrations?

If you set KAMEL_INSTALL_DEFAULT_KAMELETS=false to the operator's env, Kamelets installation can be suppressed. If you are using Camel K 1.7.0 you can also do:

kamel install --operator-env-vars=KAMEL_INSTALL_DEFAULT_KAMELETS=false

Thank you for your reply!

I have patched the camel k operator deployment env with your solution, it is working now and suppressing the kamelets installation when i create an IntegrationPlatform in other namespaces. A question on this: if I'm using Camel K 1.6.0, is this the only way to go about setting that env variable?

Also, I noticed that a CamelCatalog CR is also created when I create the IntegrationPlatform via helm, and it remains in the namespace when I remove the IntegrationPlatform. Is there also a way to clean this up?

The reason for these questions, and us not using the Kamel CLI uninstall option, is because we use Camel K CRDs (such as IntegrationPlatform and Integration) within a helm chart for our integration use cases. Hence when I uninstall the helm chart, I would like to clean up the Kamelets and CamelCatalog which are created as a by-product by the camel k operator.

Edit: Have performed upgrade of Camel K Operator to 1.7.0, hence the question has been answered.
