Automatic merge from submit-queue (batch tested with PRs 59873, 59933, 59923, 59944, 59953). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Fix pod scheduled. Fix `PodScheduled` condition. The test `[k8s.io] EquivalenceCache [Serial] validates pod affinity works properly when new replica pod is scheduled` for cri-containerd is flaky. The reason is that it assume all existing pods should have `PodScheduled` condition, but it is not the case: ``` Feb 15 15:31:01.359: INFO: with-label-390d246e-1265-11e8-beb8-0a580a3c7b55 bootstrap-e2e-minion-group-l6qw Running [{Initialized True 0001-01-01 00:00:00 +0000 UTC 2018-02-15 15:30:59 +0000 UTC } {Ready True 0001-01-01 00:00:00 +0000 UTC 2018-02-15 15:31:00 +0000 UTC } {PodScheduled True 0001-01-01 00:00:00 +0000 UTC 2018-02-15 15:30:59 +0000 UTC }] Feb 15 15:31:01.359: INFO: calico-node-7mzxc bootstrap-e2e-minion-group-hztx Running [{Initialized True 0001-01-01 00:00:00 +0000 UTC 2018-02-15 14:17:05 +0000 UTC } {Ready True 0001-01-01 00:00:00 +0000 UTC 2018-02-15 14:17:59 +0000 UTC }] Feb 15 15:31:01.359: INFO: calico-node-kvrsx bootstrap-e2e-minion-group-l6qw Running [{Initialized True 0001-01-01 00:00:00 +0000 UTC 2018-02-15 15:24:54 +0000 UTC } {Ready True 0001-01-01 00:00:00 +0000 UTC 2018-02-15 15:25:20 +0000 UTC }] Feb 15 15:31:01.359: INFO: calico-node-llwjh ``` I'm not sure why this doesn't happen to docker. One theory is that we don't prepull image in cri-containerd, and we do start pod a bit faster for cri-containerd, and that exposes the race condition. /cc @kubernetes/sig-node-bugs Signed-off-by: Lantao Liu <lantaol@google.com> **What this PR does / why we need it**: **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # **Special notes for your reviewer**: **Release note**: ```release-note none ``` |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
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.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
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
For the full story, head over to the developer's documentation.
Support
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.
