Automatic merge from submit-queue e2e: require minimum completeness in deployment tests @janetkuo should reduce deployment-related flakes For example: https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-gci-gke/5334#k8sio-deployment-scaled-rollout-deployment-should-not-block-on-annotation-check Deployment with 5 pods, all of them updated to the latest replica set. For some reason one of them is never scheduled and even though the strategy parameters in the Deployment allow 2 maxUnavailable the test is stuck for 5mins waiting for the last pod. ``` I0228 12:33:31.406] Feb 28 12:33:20.255: INFO: Pod nginx-2629236890-r7z5n is not available: I0228 12:33:31.406] {TypeMeta:{Kind: APIVersion:} ObjectMeta:{Name:nginx-2629236890-r7z5n GenerateName:nginx-2629236890- Namespace:e2e-tests-deployment-gctjw SelfLink:/api/v1/namespaces/e2e-tests-deployment-gctjw/pods/nginx-2629236890-r7z5n UID:7095ad3e-fdf4-11e6-af4a-42010af00010 ResourceVersion:7804 Generation:0 CreationTimestamp:2017-02-28 12:28:18.408376434 -0800 PST DeletionTimestamp:<nil> DeletionGracePeriodSeconds:<nil> Labels:map[pod-template-hash:2629236890 name:nginx] Annotations:map[kubernetes.io/created-by:{"kind":"SerializedReference","apiVersion":"v1","reference":{"kind":"ReplicaSet","namespace":"e2e-tests-deployment-gctjw","name":"nginx-2629236890","uid":"7085ba3f-fdf4-11e6-af4a-42010af00010","apiVersion":"extensions","resourceVersion":"7743"}} I0228 12:33:31.407] ] OwnerReferences:[{APIVersion:extensions/v1beta1 Kind:ReplicaSet Name:nginx-2629236890 UID:7085ba3f-fdf4-11e6-af4a-42010af00010 Controller:0xc420beccf0}] Finalizers:[] ClusterName:} Spec:{Volumes:[{Name:default-token-58h80 VolumeSource:{HostPath:nil EmptyDir:nil GCEPersistentDisk:nil AWSElasticBlockStore:nil GitRepo:nil Secret:&SecretVolumeSource{SecretName:default-token-58h80,Items:[],DefaultMode:*420,Optional:nil,} NFS:nil ISCSI:nil Glusterfs:nil PersistentVolumeClaim:nil RBD:nil FlexVolume:nil Cinder:nil CephFS:nil Flocker:nil DownwardAPI:nil FC:nil AzureFile:nil ConfigMap:nil VsphereVolume:nil Quobyte:nil AzureDisk:nil PhotonPersistentDisk:nil Projected:nil}}] InitContainers:[] Containers:[{Name:nginx Image:gcr.io/google_containers/update-demo:kitten Command:[] Args:[] WorkingDir: Ports:[] EnvFrom:[] Env:[] Resources:{Limits:map[] Requests:map[]} VolumeMounts:[{Name:default-token-58h80 ReadOnly:true MountPath:/var/run/secrets/kubernetes.io/serviceaccount SubPath:}] LivenessProbe:nil ReadinessProbe:nil Lifecycle:nil TerminationMessagePath:/dev/termination-log TerminationMessagePolicy:File ImagePullPolicy:IfNotPresent SecurityContext:nil Stdin:false StdinOnce:false TTY:false}] RestartPolicy:Always TerminationGracePeriodSeconds:0xc420becd28 ActiveDeadlineSeconds:<nil> DNSPolicy:ClusterFirst NodeSelector:map[] ServiceAccountName:default DeprecatedServiceAccount:default AutomountServiceAccountToken:<nil> NodeName:gke-bootstrap-e2e-default-pool-800b6140-fsl5 HostNetwork:false HostPID:false HostIPC:false SecurityContext:&PodSecurityContext{SELinuxOptions:nil,RunAsUser:nil,RunAsNonRoot:nil,SupplementalGroups:[],FSGroup:nil,} ImagePullSecrets:[] Hostname: Subdomain: Affinity:nil SchedulerName:default-scheduler Tolerations:[]} Status:{Phase:Pending Conditions:[{Type:Initialized Status:True LastProbeTime:0001-01-01 00:00:00 +0000 UTC LastTransitionTime:2017-02-28 12:28:18 -0800 PST Reason: Message:} {Type:Ready Status:False LastProbeTime:0001-01-01 00:00:00 +0000 UTC LastTransitionTime:2017-02-28 12:28:18 -0800 PST Reason:ContainersNotReady Message:containers with unready status: [nginx]} {Type:PodScheduled Status:True LastProbeTime:0001-01-01 00:00:00 +0000 UTC LastTransitionTime:2017-02-28 12:28:18 -0800 PST Reason: Message:}] Message: Reason: HostIP:10.240.0.2 PodIP: StartTime:2017-02-28 12:28:18 -0800 PST InitContainerStatuses:[] ContainerStatuses:[{Name:nginx State:{Waiting:&ContainerStateWaiting{Reason:ContainerCreating,Message:,} Running:nil Terminated:nil} LastTerminationState:{Waiting:nil Running:nil Terminated:nil} Ready:false RestartCount:0 Image:gcr.io/google_containers/update-demo:kitten ImageID: ContainerID:}] QOSClass:BestEffort}} ``` @kubernetes/sig-apps-misc |

Kubernetes
Introduction
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications. Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF).
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Are you ...
- Interested in learning more about using Kubernetes?
- See our documentation on kubernetes.io.
- Try our interactive tutorial.
- Take a free course on Scalable Microservices with Kubernetes.
- Interested in developing the core Kubernetes code base, developing tools using the Kubernetes API or helping in anyway possible? Keep reading!
Code of Conduct
The Kubernetes community abides by the CNCF code of conduct. Here is an excerpt:
As contributors and maintainers of this project, and in the interest of fostering an open and welcoming community, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.
Community
Do you want to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented?. If you are a company, you should consider joining the CNCF. For details about who's involved in CNCF and how Kubernetes plays a role, read the announcement. For general information about our community, see the website community page.
- Join us on social media (Twitter, Google+) and read our blog.
- Ask questions and help answer them on Slack or Stack Overflow.
- Attend our key events (kubecon, cloudnativecon, weekly community meeting).
- Join a Special Interest Group (SIG).
Contribute
If you're interested in being a contributor and want to get involved in developing Kubernetes, get started with this reading:
- The community expectations
- The contributor guidelines
- The Kubernetes Developer Guide
You will then most certainly gain a lot from joining a SIG, attending the regular hangouts as well as the community meeting.
If you have an idea for a new feature, see the Kubernetes Features repository for a list of features that are coming in new releases as well as details on how to propose one.
Building Kubernetes for the impatient
If you want to build Kubernetes right away there are two options:
- You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
- You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
If you are less impatient, head over to the developer's documentation.
Support
While there are many different channels that you can use to get hold of us (Slack, Stack Overflow, Issues, Forums/Mailing lists), you can help make sure that we are efficient in getting you the help that you need.
If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another. We don't bite!
