kubelet
Synopsis
The kubelet is the primary "node agent" that runs on each node. It can register the node with the apiserver using one of: the hostname; a flag to override the hostname; or specific logic for a cloud provider.
The kubelet works in terms of a PodSpec. A PodSpec is a YAML or JSON object that describes a pod. The kubelet takes a set of PodSpecs that are provided through various mechanisms (primarily through the apiserver) and ensures that the containers described in those PodSpecs are running and healthy. The kubelet doesn't manage containers which were not created by Kubernetes.
Other than from a PodSpec from the apiserver, there are three ways that a container manifest can be provided to the Kubelet.
File: Path passed as a flag on the command line. Files under this path will be monitored periodically for updates. The monitoring period is 20s by default and is configurable via a flag.
HTTP endpoint: HTTP endpoint passed as a parameter on the command line. This endpoint is checked every 20 seconds (also configurable with a flag).
HTTP server: The kubelet can also listen for HTTP and respond to a simple API (underspec'd currently) to submit a new manifest.

(DEPRECATED: This parameter should be set via the config file specified by the Kubelet's --config flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.) | |
| --tls-min-version string | |
| Minimum TLS version supported. Possible values: `VersionTLS10`, `VersionTLS11`, `VersionTLS12`, `VersionTLS13` (DEPRECATED: This parameter should be set via the config file specified by the Kubelet's `--config` flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.) | |
| --tls-private-key-file string | |
| File containing x509 private key matching `--tls-cert-file`. (DEPRECATED: This parameter should be set via the config file specified by the Kubelet's `--config` flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.) | |
| --topology-manager-policy string Default: `none` | |
| Topology Manager policy to use. Possible values: `none`, `best-effort`, `restricted`, `single-numa-node`. (DEPRECATED: This parameter should be set via the config file specified by the Kubelet's `--config` flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.) | |
| -v, --v Level | |
| Number for the log level verbosity | |
| --version version[=true] | |
| Print version information and quit | |
| --vmodule moduleSpec | |
| Comma-separated list of `pattern=N` settings for file-filtered logging | |
| --volume-plugin-dir string Default: `/usr/libexec/kubernetes/kubelet-plugins/volume/exec/` | |
| The full path of the directory in which to search for additional third party volume plugins. (DEPRECATED: This parameter should be set via the config file specified by the Kubelet's `--config` flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.) | |
| --volume-stats-agg-period duration Default: `1m0s` | |
| Specifies interval for kubelet to calculate and cache the volume disk usage for all pods and volumes. To disable volume calculations, set to `0`. (DEPRECATED: This parameter should be set via the config file specified by the Kubelet's `--config` flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.) | |
