func (*HPAUpgradeTest) Test

func (t *HPAUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

Test waits for upgrade to complete and verifies if HPA works correctly.

type IngressUpgradeTest

type IngressUpgradeTest struct {
	// contains filtered or unexported fields
}

IngressUpgradeTest adapts the Ingress e2e for upgrade testing

func (*IngressUpgradeTest) Setup

func (t *IngressUpgradeTest) Setup(f *framework.Framework)

Setup creates a GLBC, allocates an ip, and an ingress resource, then waits for a successful connectivity check to the ip.

func (*IngressUpgradeTest) Teardown

func (t *IngressUpgradeTest) Teardown(f *framework.Framework)

Teardown cleans up any remaining resources.

func (*IngressUpgradeTest) Test

func (t *IngressUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

Test waits for the upgrade to complete, and then verifies with a connectvity check to the loadbalancer ip.

type JobUpgradeTest

type JobUpgradeTest struct {
	// contains filtered or unexported fields
}

JobUpgradeTest is a test harness for batch Jobs.

func (*JobUpgradeTest) Setup

func (t *JobUpgradeTest) Setup(f *framework.Framework)

Setup starts a Job with a parallelism of 2 and 2 completions running.

func (*JobUpgradeTest) Teardown

func (t *JobUpgradeTest) Teardown(f *framework.Framework)

Teardown cleans up any remaining resources.

func (*JobUpgradeTest) Test

func (t *JobUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

Test verifies that the Jobs Pods are running after the an upgrade

type PersistentVolumeUpgradeTest

type PersistentVolumeUpgradeTest struct {
	// contains filtered or unexported fields
}

PersistentVolumeUpgradeTest test that a pv is available before and after a cluster upgrade.

func (*PersistentVolumeUpgradeTest) Setup

Setup creates a pv and then verifies that a pod can consume it. The pod writes data to the volume.

func (*PersistentVolumeUpgradeTest) Teardown

Teardown cleans up any remaining resources.

func (*PersistentVolumeUpgradeTest) Test

func (t *PersistentVolumeUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

Test waits for the upgrade to complete, and then verifies that a pod can still consume the pv and that the volume data persists.

type SecretUpgradeTest

type SecretUpgradeTest struct {
	// contains filtered or unexported fields
}

SecretUpgradeTest test that a secret is available before and after a cluster upgrade.

func (*SecretUpgradeTest) Setup

func (t *SecretUpgradeTest) Setup(f *framework.Framework)

Setup creates a secret and then verifies that a pod can consume it.

func (*SecretUpgradeTest) Teardown

func (t *SecretUpgradeTest) Teardown(f *framework.Framework)

Teardown cleans up any remaining resources.

func (*SecretUpgradeTest) Test

func (t *SecretUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

Test waits for the upgrade to complete, and then verifies that a pod can still consume the secret.

type ServiceUpgradeTest

type ServiceUpgradeTest struct {
	// contains filtered or unexported fields
}

ServiceUpgradeTest tests that a service is available before and after a cluster upgrade. During a master-only upgrade, it will test that a service remains available during the upgrade.

func (*ServiceUpgradeTest) Setup

func (t *ServiceUpgradeTest) Setup(f *framework.Framework)

type StatefulSetUpgradeTest

type StatefulSetUpgradeTest struct {
	// contains filtered or unexported fields
}

StatefulSetUpgradeTest implements an upgrade test harness for StatefulSet upgrade testing.

func (*StatefulSetUpgradeTest) Setup

func (*StatefulSetUpgradeTest) Test

func (t *StatefulSetUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

Waits for the upgrade to complete and verifies the StatefulSet basic functionality

type SysctlUpgradeTest

type SysctlUpgradeTest struct {
	// contains filtered or unexported fields
}

SecretUpgradeTest tests that a pod with sysctls runs before and after an upgrade. During a master upgrade, the exact pod is expected to stay running. A pod with unsafe sysctls is expected to keep failing before and after the upgrade.

func (*SysctlUpgradeTest) Setup

func (t *SysctlUpgradeTest) Setup(f *framework.Framework)

Setup creates two pods: one with safe sysctls, one with unsafe sysctls. It checks that the former launched and the later is rejected.

func (*SysctlUpgradeTest) Teardown

func (t *SysctlUpgradeTest) Teardown(f *framework.Framework)

Teardown cleans up any remaining resources.

func (*SysctlUpgradeTest) Test

func (t *SysctlUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

Test waits for the upgrade to complete, and then verifies that a pod can still consume the ConfigMap.

type Test

type Test interface {
	// Setup should create and verify whatever objects need to
	// exist before the upgrade disruption starts.
	Setup(f *framework.Framework)

	// Test will run during the upgrade. When the upgrade is
	// complete, done will be closed and final validation can
	// begin.
	Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)

	// TearDown should clean up any objects that are created that
	// aren't already cleaned up by the framework.
	Teardown(f *framework.Framework)
}

Test is an interface for upgrade tests.

type UpgradeType

type UpgradeType int

UpgradeType represents different types of upgrades.

const (
	// MasterUpgrade indicates that only the master is being upgraded.
	MasterUpgrade UpgradeType = iota

	// NodeUpgrade indicates that only the nodes are being upgraded.
	NodeUpgrade

	// ClusterUpgrade indicates that both master and nodes are
	// being upgraded.
	ClusterUpgrade

	// EtcdUpgrade indicates that only etcd is being upgraded (or migrated
	// between storage versions).
	EtcdUpgrade
)
