Types ¶
type KubeletFlags ¶ added in v1.7.1
type KubeletFlags struct {
KubeConfig flag.StringFlag
BootstrapKubeconfig string
// If true, an invalid KubeConfig will result in the Kubelet exiting with an error.
RequireKubeConfig bool
APIServerList []string // Deprecated -- use KubeConfig instead
// 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 the local manifest, 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
// DockershimRootDirectory is the path to the dockershim root directory. Defaults to
// /var/lib/dockershim if unset. Exposed for integration testing (e.g. in OpenShift).
DockershimRootDirectory string
// This flag, if set, sets the unique id of the instance that an external provider (i.e. cloudprovider)
// can use to identify a specific node
ProviderID string
}
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 KubeletServer ¶
type KubeletServer struct {
KubeletFlags
componentconfig.KubeletConfiguration
}
KubeletServer encapsulates all of the parameters necessary for starting up a kubelet. These can either be set via command line or directly.
func NewKubeletServer ¶
func NewKubeletServer() *KubeletServer
NewKubeletServer will create a new KubeletServer with default values.
