When creating ext3/ext4 volume, disable reserved blocks **What this PR does / why we need it**: When creating ext3/ext4 volume, `mkfs` defaults to reserving 5% of the volume for the super-user (root). This patch changes the `mkfs` to pass `-m0` to disable this setting. Rationale: Reserving a percentage of the volume is generally a neither useful nor desirable feature for volumes that aren't used as root file systems for Linux distributions, since the reserved portion becomes unavailable for non-root users. For containers, the general case is to use the entire volume for data, without running as root. The case where one might want reserved blocks enabled is much rarer. **Special notes for your reviewer**: I also added some comments to describe the flags passed to `mkfs`. **Release note**: ```release-note Changes ext3/ext4 volume creation to not reserve any portion of the volume for the root user. ```
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.
