Uninstalling Camel K
We’re sad to see you go, but If you really need to, it is possible to completely uninstall Camel K from your cluster. The uninstalling procedure typically removes the operator but keeps Custom Resource Definition and any Integration which was previously running. They can be removed by the user by an additional cleaning operation.
Uninstall via Helm
The Helm procedure takes care to delete only the operator Deployment:
$ helm uninstall camel-kCheck instructions on Camel K Helm page to remove CRDs and any other installation resource.
Uninstall via Operator Hub
In order to uninstall via OLM, you’ll need to identify and remove the Subscription custom resource related to Camel K. Check instructions on uninstall an operator page from OLM.
Uninstall via Kustomize
Uninstalling via Kustomize may require you to store the configuration you’ve used at install time and delete the applied resources. However this is something we discourage as it may remove also the application that are running and you may not want to delete (see generic cleaning for an alternative approach).
| this operation may remove CRDs and any application that is still running. |
$ kustomize build 'overlays/my-configuration' | kubectl delete -f -Uninstall cleaning cluster resources
Another alternative is to delete the resources the operator is using in a controlled way by cleaning them one by one.
Uninstall operator only (keeps CRDs and any running Integration)
In order to remove the operator and any configuration resource it uses you’ll need to perform the following cleaning operation. Here we’re assuming you have installed an operator in the namespace camel-k:
$ kubectl delete deploy -l app=camel-k -n camel-k
$ kubectl delete configmap,secret,sa,rolebindings,clusterrolebindings,roles,clusterroles,integrationplatform -l app=camel-k -n camel-kNotice that you need to perform two operation to let the Kubernetes finalizers running in the Deployment object to complete before removing any required additional resource (ie, the ServiceAccount holding such privileges).
| CRDs and Integration will be maintained alive and running. |
Uninstall CRDs (and running Integration)
In order to remove the CRDs you need to execute:
$ kubectl delete crd -l app=camel-k| Integration will be garbage collected by the cluster and so any running application. |
Verify your cluster
To verify that all resources have been removed you can use the following command:
kubectl get all,configmap,rolebindings,clusterrolebindings,secrets,sa,roles,clusterroles,crd -l 'app=camel-k'
