Add configuration for the agent itself. Currently the only control enables access to Node Resource Topology Custom Resources and it is on by default. Update the agent to honor its configuration. Signed-off-by: Krisztian Litkey <[email protected]>
Add support for tapping into the kubelet's pod resource API to query extra information about resources assigned to pods and containers. Use such a new client to expose agent functions for listing and querying pod resources, both synchronously and asynchronously. Signed-off-by: Krisztian Litkey <[email protected]>
Try querying Pod Resource API and generate extra topology hints using container device assignments listed there. Signed-off-by: Krisztian Litkey <[email protected]>
Bind-mount kubelet pod-resources directory read-only to plugin daemonset, to provide access to kubelet pod-resources socket. Signed-off-by: Krisztian Litkey <[email protected]>

This patch series
Pod Resource API queries are triggered asynchronously during pod creation/handling
RunPodSandboxNRI events. Container creation waits for any pending queries (with a short timeout) then generates extra topology hints if the results contain devices with declared NUMA-locality. The existing device allow-/deny-annotations can be used to explicitly allow or deny topology hints corresponding to Pod Resource API hints.
