US 2022/0109605 A1 · Implementing Affinity and Anti-Affinity with Kubernetes

Abstract

A KUBERNETES installation processes a script and invokes a scheduling agent in response to encountering an instruction to create a pod. The scheduling agent is an agent of an orchestrator and performs tasks such as identifying a selected node, creating multiple interface objects with multiple IP addresses, and creating storage volumes in coordination with the orchestrator. Upon creation, the pod may call a CNI that is an agent of the orchestrator in order to configure the pod to use the multiple interface objects. The pod may call a CSI that is an agent of the orchestrator in order to bind a storage volume to the pod. The scheduling agent may coordinate with the orchestrator to implement affinity and anti-affinity rules for placement of pods and storage volumes. The script may also be transformed by the orchestrator in order to insert instructions implementing affinity and ant-affinity rules.

Dependent claims

A method comprising:

processing, using a first orchestration platform executing in a network environment including one or more computer systems connected by a network, a script, the script including a specification for a pod;
in response to the specification for the pod, calling, by the first orchestration platform, a second orchestration platform executing in the network environment;
instructing, by the second orchestration platform, the first orchestration platform to create the pod on a selected node, the selected node being one of the one or more computer systems meeting one or more rules, the one or more rules including one or both of affinity rules and anti-affinity rules;
and
creating, by the first orchestration platform, the pod on the selected node.
