Functions

func BuildSUT

func BuildSUT(client *kubernetes.Clientset, s *config.PerfScenarios) error

BuildSUT Build the k8s env to run network performance tests

func CreateDeployment

func CreateDeployment(dp DeploymentParams, client *kubernetes.Clientset) (*appsv1.Deployment, error)

CreateDeployment will create the different deployments we need to do network performance tests

func CreateService

func CreateService(sp ServiceParams, client *kubernetes.Clientset) (*apiv1.Service, error)

CreateService will build a k8s service

func DestroyDeployment

func DestroyDeployment(client *kubernetes.Clientset, dp appsv1.Deployment) error

DestroyDeployment cleans up a specific deployment from a namespace

func DestroyService

func DestroyService(client *kubernetes.Clientset, serv apiv1.Service) error

DestroyService cleans up a specific service from a namespace

func GetDeployments

func GetDeployments(client *kubernetes.Clientset, namespace string) (*appsv1.DeploymentList, error)

GetDeployments retrieve all deployments for a given namespace, in this case for netperf

func GetPodNodeInfo

func GetPodNodeInfo(c *kubernetes.Clientset, dp DeploymentParams) (metrics.NodeInfo, error)

GetPodNodeInfo collects the node information for a specific pod

func GetPods

func GetPods(c *kubernetes.Clientset, dp DeploymentParams) (apiv1.PodList, error)

GetPods searches for a specific set of pods from DeploymentParms It returns a PodList if the deployment is found. NOTE : Since we can update the replicas to be > 1, is why I return a PodList.

func GetServices

func GetServices(client *kubernetes.Clientset, namespace string) (*apiv1.ServiceList, error)

GetServices retrieve all services for a given namespoace, in this case for netperf

func GetZone

func GetZone(c *kubernetes.Clientset) (string, int, error)

GetZone will determine if we have a multiAZ/Zone cloud.

func WaitForReady

func WaitForReady(c *kubernetes.Clientset, dp DeploymentParams) (bool, error)

WaitForReady accepts the client and deployment params to determine which pods to watch. It will return a bool based on if the pods ever become ready before we move on.

Types

type DeploymentParams

type DeploymentParams struct {
	HostNetwork     bool
	Name            string
