- /var/lib/docker should be mount read-write, because kubelet needs to update /etc/resolv.conf file in container, see #29378 - /var/lib/kubelet should be mount rslave, because mountpoints under this directory must be propagated to other containers - `--pid=host` is needed to run `nsenter --mount=/rootfs/proc/1/ns/mnt -- /usr/bin/systemd-run --scope` correctly - configure cluster dns for kubelet running in a container - should propagate sub-mounts of / to kubelet for local volume - Use rslave to mount /var/lib/docker/ so we can see what the host mounts under this path. - Keep containerized kubelet flags same as non-containerized and check kubelet is running or not. - Use `all_kubelet_flags` to share kubelet flags.
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.
