What is the role of a network plugin that follows the container network interface specification?
選択肢
- It decides which node each Pod should run on by comparing the resources the Pod asks for with the resources each node still has available, and it then records that decision so that the component which starts containers on the chosen node knows what it is expected to start.
- It is invoked when a Pod is set up to attach it to the network and give it an address, so Pods can reach each other across nodes.
- It provides the stable address that clients use to reach a set of Pods, so a Pod has no address of its own until something outside the cluster asked for it.
- It stores the container images on each node.
