Functions

func KubeletConfigDirCWDDir

func KubeletConfigDirCWDDir() (string, error)

func RunE2EServices

func RunE2EServices(t *testing.T)

RunE2EServices actually start the e2e services. This function is used to start e2e services in current process. This is only used in run-services-mode.

func RunKubelet

func RunKubelet(featureGates map[string]bool)

RunKubelet starts kubelet and waits for termination signal. Once receives the termination signal, it will stop the kubelet gracefully.

func SetFeatureGatesForInProcessComponents

func SetFeatureGatesForInProcessComponents(featureGates map[string]bool) error

func WriteKubeletConfigFile

func WriteKubeletConfigFile(internal *kubeletconfig.KubeletConfiguration, path string) error

WriteKubeletConfigFile writes the kubelet config file based on the args and returns the filename

Types

type APIServer

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

APIServer is a server which manages apiserver.

func NewAPIServer

func NewAPIServer(storageConfig storagebackend.Config) *APIServer

NewAPIServer creates an apiserver.

func (*APIServer) Name

func (a *APIServer) Name() string

Name returns the name of APIServer.

func (*APIServer) Start

func (a *APIServer) Start() error

Start starts the apiserver, returns when apiserver is ready.

func (*APIServer) Stop

func (a *APIServer) Stop() error

Stop stops the apiserver. Currently, there is no way to stop the apiserver. The function is here only for completion.

type E2EServices

type E2EServices struct {
	// contains filtered or unexported fields
}

E2EServices starts and stops e2e services in a separate process. The test uses it to start and stop all e2e services.

func NewE2EServices

func NewE2EServices(monitorParent bool) *E2EServices

NewE2EServices returns a new E2EServices instance.

func (*E2EServices) Start

func (e *E2EServices) Start(featureGates map[string]bool) error

Start starts the e2e services in another process by calling back into the test binary. Returns when all e2e services are ready or an error.

We want to statically link e2e services into the test binary, but we don't want their glog output to pollute the test result. So we run the binary in run-services-mode to start e2e services in another process. The function starts 2 processes: * internal e2e services: services which statically linked in the test binary - apiserver, etcd and namespace controller. * kubelet: kubelet binary is outside. (We plan to move main kubelet start logic out when we have standard kubelet launcher)

func (*E2EServices) Stop

func (e *E2EServices) Stop()

Stop stops the e2e services.

type LogFileData

type LogFileData struct {
	// Name of the log file.
	Name string `json:"name"`
	// Files are possible absolute paths of the log file.
	Files []string `json:"files"`
	// JournalctlCommand is the journalctl command to get log.
	JournalctlCommand []string `json:"journalctl"`
}

LogFileData holds data about logfiles to fetch with a journalctl command or file from a node's file system.

type NamespaceController

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

NamespaceController is a server which manages namespace controller.

func NewNamespaceController

func NewNamespaceController(host string) *NamespaceController

NewNamespaceController creates a new namespace controller.

func (*NamespaceController) Name

func (n *NamespaceController) Name() string

Name returns the name of namespace controller.

func (*NamespaceController) Start

func (n *NamespaceController) Start(ctx context.Context) error

Start starts the namespace controller.

func (*NamespaceController) Stop

func (n *NamespaceController) Stop() error

Stop stops the namespace controller.
