Types

type OnDeleteFunc

type OnDeleteFunc func(string, string) error

OnDeleteFunc is a function called on cluster

type OnIncreaseFunc

type OnIncreaseFunc func(string, int) error

OnIncreaseFunc is a function called on node group increase in TestCloudProvider. First parameter is the NodeGroup id, second is the increase delta.

type TestCloudProvider

type TestCloudProvider struct {
	sync.Mutex
	// contains filtered or unexported fields
}

TestCloudProvider is a dummy cloud provider to be used in tests.

func NewTestCloudProvider

func NewTestCloudProvider(onIncrease OnIncreaseFunc, onDelete OnDeleteFunc) *TestCloudProvider

NewTestCloudProvider builds new TestCloudProvider

func (*TestCloudProvider) AddNode

func (tcp *TestCloudProvider) AddNode(nodeGroupId string, node *apiv1.Node)

AddNode adds the given node to the group.

func (*TestCloudProvider) AddNodeGroup

func (tcp *TestCloudProvider) AddNodeGroup(id string, min int, max int, size int)

AddNodeGroup adds node group to test cloud provider.

func (*TestCloudProvider) Name

func (tcp *TestCloudProvider) Name() string

Name returns name of the cloud provider.

func (*TestCloudProvider) NodeGroupForNode

func (tcp *TestCloudProvider) NodeGroupForNode(node *apiv1.Node) (cloudprovider.NodeGroup, error)

NodeGroupForNode returns the node group for the given node, nil if the node should not be processed by cluster autoscaler, or non-nil error if such occurred.

func (*TestCloudProvider) NodeGroups

func (tcp *TestCloudProvider) NodeGroups() []cloudprovider.NodeGroup

NodeGroups returns all node groups configured for this cloud provider.

type TestNodeGroup

type TestNodeGroup struct {
	sync.Mutex
	// contains filtered or unexported fields
}

TestNodeGroup is a node group used by TestCloudProvider.

func (*TestNodeGroup) Debug

func (tng *TestNodeGroup) Debug() string

Debug returns a string containing all information regarding this node group.

func (*TestNodeGroup) DecreaseTargetSize

func (tng *TestNodeGroup) DecreaseTargetSize(delta int) error

DecreaseTargetSize decreases the target size of the node group. This function doesn't permit to delete any existing node and can be used only to reduce the request for new nodes that have not been yet fulfilled. Delta should be negative.

func (*TestNodeGroup) DeleteNodes

func (tng *TestNodeGroup) DeleteNodes(nodes []*apiv1.Node) error

DeleteNodes deletes nodes from this node group. Error is returned either on failure or if the given node doesn't belong to this node group. This function should wait until node group size is updated.

func (*TestNodeGroup) Id

func (tng *TestNodeGroup) Id() string

Id returns an unique identifier of the node group.

func (*TestNodeGroup) IncreaseSize

func (tng *TestNodeGroup) IncreaseSize(delta int) error

IncreaseSize increases the size of the node group. To delete a node you need to explicitly name it and use DeleteNode. This function should wait until node group size is updated.

func (*TestNodeGroup) MaxSize

func (tng *TestNodeGroup) MaxSize() int

MaxSize returns maximum size of the node group.

func (*TestNodeGroup) MinSize

func (tng *TestNodeGroup) MinSize() int

MinSize returns minimum size of the node group.

func (*TestNodeGroup) Nodes

func (tng *TestNodeGroup) Nodes() ([]string, error)

Nodes returns a list of all nodes that belong to this node group.

func (*TestNodeGroup) TargetSize

func (tng *TestNodeGroup) TargetSize() (int, error)

TargetSize returns the current target size of the node group. It is possible that the number of nodes in Kubernetes is different at the moment but should be equal to Size() once everything stabilizes (new nodes finish startup and registration or removed nodes are deleted completely)
