Variables

View Source 
var MaxContainerFailures = 0

Maximum container failures this test tolerates before failing.

Functions

func BadEvents added in v0.21.2 

func BadEvents(events []*api.Event) int

Prints the histogram of the events and returns the number of bad events.

func ClusterLevelLoggingWithElasticsearch(f *Framework)

ClusterLevelLoggingWithElasticsearch is an end to end test for cluster level logging.

func DeleteRC 

func DeleteRC(c *client.Client, ns, name string) error

Delete a Replication Controller and all pods it spawned

func FailedContainers added in v0.21.2 

func FailedContainers(pod *api.Pod) map[string]ContainerFailures

FailedContainers inspects all containers in a pod and returns failure information for containers that have failed or been restarted. A map is returned where the key is the containerID and the value is a struct containing the restart and failure information

func Failf 

func Failf(format string, a ...interface{})

func GetKubeletPods added in v0.21.2 

func GetKubeletPods(c *client.Client, node string) (*api.PodList, error)

GetKubeletPods retrieves the list of running pods on the kubelet. The pods includes necessary information (e.g., UID, name, namespace for pods/containers), but do not contain the full spec.

func HighLatencyRequests added in v0.21.2 

func HighLatencyRequests(c *client.Client, threshold time.Duration, ignoredResources util.StringSet) (int, error)

Prints summary metrics for request types with latency above threshold and returns number of such request types.

func NodeSSHHosts added in v0.21.2 

func NodeSSHHosts(c *client.Client) ([]string, error)

func RunRC 

func RunRC(config RCConfig) error

RunRC Launches (and verifies correctness) of a Replication Controller 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 SSH added in v0.21.2 

func SSH(cmd, host, provider string) (string, string, int, error)

SSH synchronously SSHs to a node running on provider and runs cmd. If there is no error performing the SSH, the stdout, stderr, and exit code are returned.
