Types ¶
type DeploymentUpgradeTest ¶
type DeploymentUpgradeTest struct {
// contains filtered or unexported fields
}
DeploymentUpgradeTest tests that a deployment is using the same replica sets before and after a cluster upgrade.
func (*DeploymentUpgradeTest) Setup ¶
func (t *DeploymentUpgradeTest) Setup(f *framework.Framework)
Setup creates a deployment and makes sure it has a new and an old replica set running.
func (*DeploymentUpgradeTest) Teardown ¶
func (t *DeploymentUpgradeTest) Teardown(f *framework.Framework)
Teardown cleans up any remaining resources.
func (*DeploymentUpgradeTest) Test ¶
func (t *DeploymentUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)
Test checks whether the replica sets for a deployment are the same after an upgrade.
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)
Setup creates a service with a load balancer and makes sure it's reachable.
func (*ServiceUpgradeTest) Teardown ¶
func (t *ServiceUpgradeTest) Teardown(f *framework.Framework)
Teardown cleans up any remaining resources.
func (*ServiceUpgradeTest) Test ¶
func (t *ServiceUpgradeTest) Test(f *framework.Framework, done <-chan struct{}, upgrade UpgradeType)
Test runs a connectivity check to the service.
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 )
