Container protection budget PPB method in K8S

The invention relates to the technical field of computers, in particular to a container protection budget PPB method in K8S, which comprises the following steps: when a voluntary interrupt request generated by a client is transmitted to an APIServer, through a PPB webhook of an admissionwebhook, analyzing a current voluntary interrupt operation in the webhook of the PPB to obtain whether the Pod number set by the PPB in a cluster is influenced after the current operation is executed, and if the Pod number set by the PPB in the cluster is satisfied, if the Pod number set by the PPB in the cluster is not influenced by the current operation, judging whether the Pod number set by the PPB in the cluster is not influenced by the current voluntary interrupt operation, and if the Pod number set by the PPB in the cluster is not influenced by the current voluntary interrupt operation. If yes, subsequent operation is carried out, and if not, the operation of the client side is refused; the container protection budget PP
