Victor Marmol	d0288f7143	Merge pull request #7301 from yujuhong/no_resurrection Kubelet: filter out terminated pods in SyncPods	2015-04-24 16:17:06 -07:00
Yu-Ju Hong	b0e6926f67	kubelet: filter out terminated pods in SyncPods Once a pod reaches a terminated state (whether failed or succeeded), it should not transit out ever again. Currently, kubelet relies on examining the dead containers to verify that the container has already been run. This is fine in most cases, but if the dead containers were garbage collected, kubelet may falsely concluded that the pod has never been run. It would then try to restart all the containers. This change eliminates most of such possibilities by pre-filtering out the pods in the final states before sending updates to per-pod workers.	2015-04-24 15:28:03 -07:00
Victor Marmol	270d8aec8b	Raise cAdvisor stats cache to 2m. This used to be 60ns which was a bug from when we switched from number of stats to duration. Seems like the type was silently converted/ignored.	2015-04-24 14:44:13 -07:00

Yu-Ju Hong	06125f37d3	Print container statuses in `kubectl get pods` `kubectl get pod` already prints one container per line. This change fills in the status for each container listed. This aims to help users quickly identify unhealthy pods (e.g. in a crash loop) at a glance. - The first row of every pod would display the pod information and status - Each row of the subsequent rows corresponds to a container in that pod: * STATUS refers to the container status (Running, Waiting, Terminated). * CREATED refers to the elapsed time since the last start time of the container. * MESSAGE is a string which explains the last termination reason, and/or the reason behind the waiting status.	2015-04-21 15:42:18 -07:00

Yu-Ju Hong	fd34441d2d	Kubelet: persist restart count of a container Currently, restart count are generated by examine dead docker containers, which are subject to background garbage collection. Therefore, the restart count is capped at 5 and can decrement if GC happens. This change leverages the container statuses recorded in the pod status as a reference point. If a container finished after the last observation, restart count is incremented on top of the last observed count. If container is created after last observation, but GC'd before the current observation time, kubelet would not be aware of the existence of such a container, and would not increase the restart count accordingly. However, the chance of this should be low, given that pod statuses are reported frequently. Also, the restart cound would still be increasing monotonically (with the exception of container insepct error).	2015-04-14 15:06:42 -07:00

Yu-Ju Hong	d01bc660b5	Kubelet: a step towards to better encapsulation of docker functions We want to stop leaking more docker details into kubelet, and we also want to consolidate some of the existing docker interfaces/structs. This change creates DockerManager as the new home of some functions in dockertools/docker.go. It also absorbs containerRunner. In addition, GetDockerPodStatus is renamed to GetPodStatus with the entire pod passed to it so that it is simialr to the what is defined in the container Runtime interface. Eventually, DockerManager should implement the container Runtime interface, and integrate DockerCache with a flag to turn on/off caching. Code in kubelet.go should not be using docker client directly.	2015-04-02 13:26:39 -07:00

Yu-Ju Hong	15e9760bd4	Kubelet: support retrieving stats using UID of mirror pod Kubelet supports retrieving stats for pods/containers with and without UID. This does not always work for the static pods because users may get the UIDs of the mirror pods from the API server, and use them to query Kubelet. In this case, Kubelet would fail to locate the containers due to mismatched UIDs. This change adds a intenral mirror to static pod UID mapping and teaches all public-facing functions to perform UID lookup before proceeding. This allows users to use either mirror or static pod's UID to retrieve stats.	2015-03-20 15:40:49 -07:00

Yu-Ju Hong	0d0fb5f07b	Kubelet: per-pod workers should avoid grabbing the pod array lock Per-pod worker syncs the pod and container status, and write the pod status in the pod status cache. Given that it already owns a copy of the pod, it can bypass the additional pod lookup step completely. This change adds a new generatePodStatusByPod() method to achieve this. In general, per-pod worker should avoid accessing the internal pod array completely, as this would may lead to high contention. This change also changes the return type of GetPodByFullName to reflect the name, and consolidates GetPodByFullName() and GetPodByName().	2015-03-19 18:25:41 -07:00

Yu-Ju Hong	929fb63b33	Sync static pods from Kubelet to the API server Currently, API server is not aware of the static pods (manifests from sources other than the API server, e.g. file and http) at all. This is inconvenient since users cannot check the static pods through kubectl. It is also sub-optimal because scheduler is unaware of the resource consumption by these static pods on the node. This change syncs the information back to the API server by creating a mirror pod via API server for each static pod. - Kubelet creates containers for the static pod, as it would do normally. - If a mirror pod gets deleted, Kubelet will re-create one. The containers are sync'd to the static pods, so they will not be affected. - If a static pod gets removed from the source (e.g. manifest file removed from the directory), the orphaned mirror pod will be deleted. Note that because events are associated with UID, and the mirror pod has a different UID than the original static pod, the events will not be shown for the mirror pod when running `kubectl describe pod <mirror_pod>`.	2015-03-17 08:45:56 -07:00

Victor Marmol	ab3c9de34b	Refactoring cAdvisor interface into a package. This will make it easier to start running the real cAdvisor alongside Kubelet. This change is primarily no-op refactoring. The main behavioral change is that we always create a cAdvisor interface and expect it to always be available. When we make a request, if cAdvisor is not connected the request fails with a connection error. This failure is handled today as well.	2015-03-09 11:19:05 -07:00

Victor Marmol	ca84aae454	Kubelet: wait up to 5m for Docker to come up. The Kubelet assumes Docker is running during its execution and on machine boot it is a race between Docker coming up and Kubelet calling Docker. This PR waits for Docker to be up before the Kubelet begins doing useful work. On timeout, Kubelet exits and expects to be restarted.	2015-03-09 09:50:34 -07:00

Yu-Ju Hong	fe70be9261	kubelet: revamp the pod/container naming scheme There are two main goals for this change. 1. Fix the naming scheme in kubelet so that it accepts DNS subdomain name/namespaces correctly (#4920). The design is discussed in #3453. 2. Prepare for syncing the static pods back to the apiserver(#4090). This includes - Eliminate the source component in the internal full pod name (#4922). Pods no longer need sources as they will all be sync'd via apiserver. - Changing the naming scheme for the static (file-, http-, and etcd-based) pods such that they are distinguishable when syncing back to the apiserver. The changes includes: * name = <pod.Name>-<hostname> * namespace = <cluster_namespace> (i.e. "default" for now). * container_name = k8s_<contianer_name>.<hash_of_container>_<pod_name>_<namespace>_<uid>_<random> Note that this is not backward-compatible, meaning the kubelet won't recognize existing running containers using the old naming scheme.	2015-03-06 13:14:45 -08:00

Yu-Ju Hong	3ccdb8db98	kubelet: reject pods on host port conflict When a host port conflict is detected, kubelet should set the pod status to fail. The failed status will then be polled by other components at a later time, which allows replication controller to create a new pod if necessary. To achieve this, this change stores the pod status information in a status map upon the detecton of port conflict. GetPodStatus() consults this status map before attempting to query docker. The entries in the status map will be removed when the pod is no longer associated with the node.	2015-03-06 10:46:49 -08:00

Victor Marmol	5d6ad845cc	Use Docker name (not ID) to parse Kubernetes components. Since the parsing function doesn't return an error all the components returned empty strings. This caused us to enforce the MaxContainerLimit as a global limit instead of a per-container limit. Fixes #4413.	2015-02-13 13:08:15 -08:00
