Query sends a command to the server and returns the Response.

RemoveCleanupAction removes a function that was installed by AddCleanupAction.

A basic test to check the deployment of an image using a ReplicaSet.

RunCleanupActions runs all functions installed by AddCleanupAction.

RunDeployment Launches (and verifies correctness) of a Deployment and will wait for all pods it spawns to become "Running".

TestE2E checks configuration parameters (specified through flags) and then runs E2E tests using the Ginkgo runner.

RunHostCmd runs the given cmd in the context of the given pod using `kubectl exec` inside of a shell.

RunHostCmdOrDie calls RunHostCmd and dies on error.

RunRC Launches (and verifies correctness) of a Replication Controller and will wait for all pods it spawns to become "Running".

RunReplicaSet launches (and verifies correctness) of a ReplicaSet and waits until all the pods it launches to reach the "Running" state.

A basic test to check the deployment of an image using a replication controller.

Check that the pods comprising a replication controller get spread evenly across available zones.

Check that the pods comprising a service get spread evenly across available zones.

SSH synchronously SSHs to a node running on provider and runs cmd.

Verifies whether 50, 90 and 99th percentiles of PodStartupLatency are within the threshold.

Verifies (currently just by logging them) the scheduling latencies.

NodeStartupThreshold is a rough estimate of the time allocated for a pod to start on a node.
