I am trying helm del --purge which not deleting one pod which is mentioned in a yaml separately, but it is deleting all the pods which are getting created by deployments or which are stateful pods.
helm del --purge <helm chart name> will delete only pods which are related with particular helm charts.
You can check all the helm charts installed on the cluster via : helm ls
you can delete helm chart using helm del <chart name>
while the pods are created separately and not part of any helm chart will not be deleted when you will run helm del --purge
So, for example, you installed MySQL using helm : helm install --name mysql stable/mysql
So when you will run helm del --purge mysql it will only delete mysql pods.
To delete the pod which are created separately you can run kubectl delete pod <pod name>
To delete the deployment :
kubectl delete deployment <deployment name>To delete statefulsets :
kubectl delete statefulset <statefulset name>
