I changed the cluster yaml file `nodeSet.config.count` value to 0 In my cluster,When i `kubectl describe es xxxx_es_id` ,the logs info is:"es26f861-fa5d-410a-acb1-b9281f6814ae" is invalid: spec.nodeSets: Required value: Elasticsearch needs to have at least one master node。
How do I skip this limit，pls

What are you trying to achieve? Can you share your YAML manifest maybe. A cluster with 0 nodes is effectively scaled down so you might as well delete the Elasticsearch cluster all together. The only exception to that rule is when you have [autoscaling](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-autoscaling.html) setup in which case we allow zero-sized nodeSets (as the autoscaler will adjust the count)

Thanks for reply！
I just want to stop my cluster instead of deleting it, just to temporarily free up resources, next time I can continue to start, but I found that it does not allow me to do so, just like the error mentioned before, I will try you to The scheme, thank you. Following is my yaml file：

Hey @w_Aaron,
as @pebrc mentioned above, we don't allow scaling down to 0. The next best thing you can do is to delete the cluster altogether (eg. `kubectl delete es -n my-eck-test es48fe28-6265-40ef-88db-6657a7380774`).
Let me know if you have any questions.
Thanks,
David
