Uninstalling ECK

Before uninstalling the operator, remove all Elastic resources in all namespaces:

kubectl get namespaces --no-headers -o custom-columns=:metadata.name \
  | xargs -n1 kubectl delete elastic --all -n

This deletes all underlying Elasticsearch, Kibana, and APM Server resources (pods, secrets, services, etc.).

Then, you can uninstall the operator:

kubectl delete -f https://download.elastic.co/downloads/eck/1.0.1/all-in-one.yaml
