This container will be used to exercise the HostIPC functionality in e2e-node tests. The version of `ipcs` shipped in busybox performs operations that get blocked by SELinux on hosts where it is enabled. The version of `ipcs` in util-linux does not perform those operations, rather it checks whether the /proc files it needs are available and proceeds to reading from them directly. Using `ipcs` from util-linux makes these tests pass, even when running under SELinux enabled, so let's use them here. Tested: On a host where Docker with SELinux enabled: - Checked that `ipcs` from busybox does not work: $ docker run busybox ipcs -m kernel not configured for shared memory - Checked that the one from this container does work: $ docker run gcr.io/kubernetes-e2e-test-images/ipc-utils-amd64:1.0 ipcs -m ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status |

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.
