SYNOPSIS

14       kubelet [OPTIONS]
15
16
17

DESCRIPTION

19       The  kubelet is the primary "node agent" that runs on each node. It can
20       register the node with the apiserver using one of: the hostname; a flag
21       to override the hostname; or specific logic for a cloud provider.
22
23
24       The  kubelet  works  in terms of a PodSpec. A PodSpec is a YAML or JSON
25       object that describes a pod. The kubelet takes a set of  PodSpecs  that
26       are  provided  through  various mechanisms (primarily through the apis‐
27       erver) and ensures that the containers described in those PodSpecs  are
28       running  and  healthy. The kubelet doesn't manage containers which were
29       not created by Kubernetes.
30
31
32       Other than from an PodSpec from the apiserver,  there  are  three  ways
33       that a container manifest can be provided to the Kubelet.
34
35
36       File:  Path passed as a flag on the command line. Files under this path
37       will be monitored periodically for updates. The  monitoring  period  is
38       20s by default and is configurable via a flag.
39
40
41       HTTP endpoint: HTTP endpoint passed as a parameter on the command line.
42       This endpoint is checked every 20 seconds  (also  configurable  with  a
43       flag).
44
45
46       HTTP server: The kubelet can also listen for HTTP and respond to a sim‐
47       ple API (underspec'd currently) to submit a new manifest.
