Types

type Driver

type Driver struct {

	// NameSuffix can be set while registering a test to deploy different
	// drivers in the same test namespace.
	NameSuffix string

	// InstanceSuffix can be set while registering a test to deploy two different
	// instances of the same driver. Used to generate unique objects in the API server.
	// The socket path is still the same.
	InstanceSuffix string

	// RollingUpdate can be set to true to enable using different socket names
	// for different pods and thus seamless upgrades. Must be supported by the kubelet!
	RollingUpdate bool

	// Name gets derived automatically from the current test namespace and
	// (if set) the NameSuffix while setting up the driver for a test.
	Name string

	// Nodes contains entries for each node selected for a test when the test runs.
	// In addition, there is one entry for a fictional node.
	Nodes map[string]KubeletPlugin

	NodeV1alpha4 bool
	NodeV1beta1  bool
	// contains filtered or unexported fields
}

func NewDriver

func NewDriver(f *framework.Framework, nodes *Nodes, configureResources func() Resources, devicesPerNode ...map[string]map[resourceapi.QualifiedName]resourceapi.DeviceAttribute) *Driver

NewDriver sets up controller (as client of the cluster) and kubelet plugin (via proxy) before the test runs. It cleans up after the test.

Call this outside of ginkgo.It, then use the instance inside ginkgo.It.

func NewDriverInstance

func NewDriverInstance(f *framework.Framework) *Driver

NewDriverInstance is a variant of NewDriver where the driver is inactive and must be started explicitly with Run. May be used inside ginkgo.It.

func (*Driver) CallCount

func (d *Driver) CallCount(m MethodInstance) int64

func (*Driver) Fail

func (d *Driver) Fail(m MethodInstance, injectError bool)

func (*Driver) IsGone

func (d *Driver) IsGone(ctx context.Context)

IsGone checks that the kubelet is done with the driver. This is done by waiting for the kubelet to remove the driver's ResourceSlices, which takes at least 5 minutes because of the delay in the kubelet. Only use this in slow tests...

func (*Driver) NewGetSlices

NewGetSlices generates a function for gomega.Eventually/Consistently which returns the ResourceSliceList.

func (*Driver) Nodenames

func (d *Driver) Nodenames() (nodenames []string)

func (*Driver) Run

func (d *Driver) Run(nodes *Nodes, configureResources func() Resources, devicesPerNode ...map[string]map[resourceapi.QualifiedName]resourceapi.DeviceAttribute)

func (*Driver) SetUp

func (d *Driver) SetUp(nodes *Nodes, resources Resources, devicesPerNode ...map[string]map[resourceapi.QualifiedName]resourceapi.DeviceAttribute)

func (*Driver) TearDown

func (d *Driver) TearDown(ctx context.Context)

type KubeletPlugin

type KubeletPlugin struct {
	*app.ExamplePlugin
	ClientSet kubernetes.Interface
}

type MethodInstance

type MethodInstance struct {
	Nodename   string
	FullMethod string
}

type Nodes

type Nodes struct {
	NodeNames []string
	// contains filtered or unexported fields
}

func NewNodes

func NewNodes(f *framework.Framework, minNodes, maxNodes int) *Nodes

NewNodes selects nodes to run the test on.

Call this outside of ginkgo.It, then use the instance inside ginkgo.It.

func NewNodesNow

func NewNodesNow(ctx context.Context, f *framework.Framework, minNodes, maxNodes int) *Nodes

NewNodesNow is a variant of NewNodes which can be used inside a ginkgo.It.

type Resources

type Resources struct {
	NodeLocal bool

	// Nodes is a fixed list of node names on which resources are
	// available. Mutually exclusive with NodeLabels.
	Nodes []string

	// Number of devices called "device-000", "device-001", ... on each node or in the cluster.
	MaxAllocations int

	// Tainted causes all devices to be published with a NoExecute taint.
	Tainted bool
}
