Types

type AgentFlags

type AgentFlags struct {
	KubeConfig          string
	BootstrapKubeconfig string

	// Insert a probability of random errors during calls to the master.
	ChaosChance float64
	// Crash immediately, rather than eating panics.
	ReallyCrashForTesting bool

	// TODO(mtaufen): It is increasingly looking like nobody actually uses the
	//                Kubelet's runonce mode anymore, so it may be a candidate
	//                for deprecation and removal.
	// If runOnce is true, the Kubelet will check the API server once for pods,
	// run those in addition to the pods specified by static pod files, and exit.
	RunOnce bool

	// HostnameOverride is the hostname used to identify the kubelet instead
	// of the actual hostname.
	HostnameOverride string
	// NodeIP is IP address of the node.
	// If set, kubelet will use this IP address for the node.
	NodeIP string

	// Container-runtime-specific options.
	config.ContainerRuntimeOptions

	// certDirectory is the directory where the TLS certs are located (by
	// default /var/run/kubernetes). If tlsCertFile and tlsPrivateKeyFile
	// are provided, this flag will be ignored.
	CertDirectory string

	// cloudProvider is the provider for cloud services.
	// +optional
	CloudProvider string

	// cAdvisorPort is the port of the localhost cAdvisor endpoint (set to 0 to disable)
	CAdvisorPort int32

	// WindowsService should be set to true if kubelet is running as a service on Windows
	// Its corresponding flag only gets registered in Windows builds
	WindowsService bool

	// containerized should be set to true if kubelet is running in a container.
	Containerized bool
	// remoteRuntimeEndpoint is the endpoint of remote runtime service
	RemoteRuntimeEndpoint string

	// lockFilePath is the path that kubelet will use to as a lock file.
	// It uses this file as a lock to synchronize with other kubelet processes
	// that may be running.
	LockFilePath string
	// ExitOnLockContention is a flag that signifies to the kubelet that it is running
	// in "bootstrap" mode. This requires that 'LockFilePath' has been set.
	// This will cause the kubelet to listen to inotify events on the lock file,
	// releasing it and exiting when another process tries to open that file.
	ExitOnLockContention bool
}

A configuration field should go in KubeletFlags instead of KubeletConfiguration if any of these are true:

• its value will never, or cannot safely be changed during the lifetime of a node
• its value cannot be safely shared between nodes at the same time (e.g. a hostname) KubeletConfiguration is intended to be shared between nodes

In general, please try to avoid adding flags or configuration fields, we already have a confusingly large amount of them. type KubeletFlags struct {

type AgentServer

type AgentServer struct {
	AgentFlags
	agent.Config
}

KubeletServer encapsulates all of the parameters necessary for starting up a kubelet. These can either be set via command line or directly.

type KubeletServer struct {
	KubeletFlags
	kubeletconfig.KubeletConfiguration
}
