func PodReady added in v1.4.5 

func PodReady(pod *v1.Pod) bool

podReady returns whether pod has a condition of Ready with a status of true. TODO: should be replaced with v1.IsPodReady

func PodRunningReady added in v1.4.5 

func PodRunningReady(p *v1.Pod) (bool, error)

func RunDeployment added in v1.5.0 

func RunDeployment(config DeploymentConfig) error

RunDeployment Launches (and verifies correctness) of a Deployment and will wait for all pods it spawns to become "Running". It's the caller's responsibility to clean up externally (i.e. use the namespace lifecycle for handling Cleanup).

func RunJob added in v1.6.0 

func RunJob(config JobConfig) error

RunJob baunches (and verifies correctness) of a Job and will wait for all pods it spawns to become "Running". It's the caller's responsibility to clean up externally (i.e. use the namespace lifecycle for handling Cleanup).

func RunReplicaSet added in v1.5.0 

func RunReplicaSet(config ReplicaSetConfig) error

RunReplicaSet launches (and verifies correctness) of a ReplicaSet and waits until all the pods it launches to reach the "Running" state. It's the caller's responsibility to clean up externally (i.e. use the namespace lifecycle for handling Cleanup).

	pod v1.Pod, waitForRunning bool, logFunc func(fmt string, args ...interface{})) error
