Yu-Ju Hong	4846c1e1b2	pleg: add an internal clock for testability ... Also add tests for the health check.	2016-03-01 17:53:03 -08:00
Yu-Ju Hong	94368df91a	kubelet: monitor the health of pleg ... PLEG is reponsible for listing the pods running on the node. If it's hung due to non-responsive container runtime or internal bugs, we should restart kubelet.	2016-03-01 17:24:27 -08:00
Yu-Ju Hong	e770f25882	pleg: add more tests for detecting missing container/pods	2016-03-01 17:23:23 -08:00

Random-Liu	96eeb812ff	kubelet: clear current pod records before relist	2016-02-28 13:19:47 -08:00
Yu-Ju Hong	388689238b	pleg: ensure the cache is updated whenever container are removed ... Even though we don't rely on the cache for garbage collection yet, we should keep it up-to-date.	2016-02-28 13:16:34 -08:00
Yu-Ju Hong	f9880d4a3a	kubelet: lower the verbosity level of some logging messages	2016-02-24 18:42:26 -08:00

Jan Chaloupka	4389b3f0d6	Rewritte util.* -> wait.* wherever reasonable	2016-02-07 12:02:20 +01:00
Yu-Ju Hong	b56ed1a8c2	Support populating the runtime cache in PLEG ... This changes does not turn on this feature (cache) for kubelet.	2016-01-13 10:19:47 -08:00
Yu-Ju Hong	73a4f8225c	PLEG should report events if a container is removed ... Currently, pleg would report a event if a container transitions from running to exited between relisting. However, if would not report any event if a container gets stopped and removed between relisting. This event will eventually be handled when the pod syncs periodically, but this is undesirable. This change ensures that we detect all such events.	2016-01-12 16:25:19 -08:00
Yu-Ju Hong	7d180b337b	Record pleg pod relist interval and latency ... Relisting latency/interval affects how quick kubelet discovers changes. Record the metrics in Prometheus to surface such information.	2016-01-04 10:56:38 -08:00
Random-Liu	3cbdf79f8c	Change original PodStatus to APIPodStatus, and start using kubelet internal PodStatus in dockertools	2015-12-04 17:37:39 -08:00
Yu-Ju Hong	bc6414a873	kubelet: add a generic pod lifecycle event generator ... This change introduces pod lifecycle event generator (PLEG), and adds a generic PLEG. The generic PLEG relies on relisting to discover container events, and is container-runtime-agnostic. Both docker and rkt are changed to use generic PLEG.	2015-11-13 09:55:36 -08:00
