Abstract: In an example, a method for provisioning a cell site in a 5G RAN may include receiving a plurality of steps involved in provisioning the cell site for the 5G RAN. In an example, provisioning the cell site may include provisioning of a physical infrastructure layer, a container orchestration platform on the physical infrastructure layer, and a containerized network function (CNF) instance associated with the 5G RAN in the container orchestration platform. Further, the method may include converting the plurality of steps into a dependency graph of tasks. The dependency graph may represent workflows and relationships between the tasks. Furthermore, based on feeding the dependency graph as an input to an orchestrator, the method may include provisioning the cell site by executing the tasks in an order according to the dependency graph.

Abstract: An example method for managing a cell site in a 5G RAN may include determining a physical infrastructure layer, a container orchestration platform on the physical infrastructure layer, and a CNF instance associated with the 5G RAN in the container orchestration platform based on a site identifier associated with the cell site. Based on the physical infrastructure layer, the container orchestration platform, and the CNF instance, the method may include building a logical site resource map representing topological information of the cell site. Further, the method may include monitoring and/or managing the cell site using the logical site resource map.

Abstract: The disclosure provides a method for orchestrating simulated events in a distributed container-based system. The method generally includes monitoring, by a chaos controller deployed in a management cluster of the container-based system, for new objects generated at the management cluster, wherein the management cluster is configured to manage a plurality of simulated workload clusters in a simulation system, based on the monitoring, discovering, by the chaos controller, a new object generated at the management cluster providing information about events intended to be simulated for one or more simulated workload clusters of the plurality of simulated workload clusters, determining a plan for orchestrating a simulation of the events in the one or more simulated workload clusters based on the information provided in the new object, and triggering the simulation of the events in accordance with the plan.

Abstract: Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for simulating nodes of a container orchestration system. An example method includes: deploying a mock node for taking on a role of actual worker nodes, wherein the mock node is provided with a first set of resources providing a first compute capacity and the mock node includes an interface for interacting with an API server of the container orchestration system; configuring the interface to present to the container orchestration system an available compute capacity of a second compute capacity; registering the mock node as an actual worker node of the cluster with the API server based on the interface of the mock node; causing the container orchestration system to deploy a plurality of application pods to the mock node; and obtaining events generated by the interface in the mock node indicating deployment and running statuses of the application pods.
