Types

type Config

type Config struct {
	Logger *zap.Logger
	Stopc  chan struct{}

	EKSConfig *eksconfig.Config
	K8SClient k8s_client.EKS

	ECRAPI ecriface.ECRAPI
}

Config defines hollow nodes configuration.

type NodeGroup

type NodeGroup interface {
	Start() error
	Stop()
	CheckNodes() (readyNodes []string, createdNodes []string, err error)
}

NodeGroup represents a set of hollow node objects.

func CreateNodeGroup

func CreateNodeGroup(cfg NodeGroupConfig) (ng NodeGroup, err error)

CreateNodeGroup creates a new hollow node group.

type NodeGroupConfig

type NodeGroupConfig struct {
	Logger         *zap.Logger
	Client         k8s_client.EKS
	Stopc          chan struct{}
	Nodes          int
	NodeLabels     map[string]string
	MaxOpenFiles   int64
	KubectlPath    string
	KubeConfigPath string
}

NodeGroupConfig is the hollow nodes configuration.

type Tester

type Tester interface {
	// Create installs hollow nodes.
	Create() error
	// Delete deletes hollow nodes.
	Delete() error
}

Tester defines hollow nodes tester.

func NewTester

func NewTester(cfg Config) (Tester, error)
