***Editor's note: today's post is by the [1.10 Release
|
||||
Team](https://github.com/kubernetes/sig-release/blob/master/releases/release-1.10/release_team.md)***
|
||||
|
||||
We’re pleased to announce the delivery of Kubernetes 1.10, our first release
|
||||
of 2018!
|
||||
|
||||
Today’s release continues to advance maturity, extensibility, and pluggability
|
||||
of Kubernetes. This newest version stabilizes features in 3 key areas,
|
||||
including storage, security, and networking. Notable additions in this release
|
||||
include the introduction of external kubectl credential providers (alpha), the
|
||||
ability to switch DNS service to CoreDNS at install time (beta), and the move
|
||||
of Container Storage Interface (CSI) and persistent local volumes to beta.
|
||||
|
||||
Let’s dive into the key features of this release:
|
||||
|
||||
## Storage - CSI and Local Storage move to beta
|
||||
|
||||
This is an impactful release for [the Storage Special Interest Group
|
||||
(SIG)](https://github.com/kubernetes/community/tree/master/sig-storage),
|
||||
marking the culmination of their work on multiple features. The [Kubernetes
|
||||
implementation](https://github.com/kubernetes/features/issues/178) of the
|
||||
[Container Storage
|
||||
Interface](https://github.com/container-storage-interface/spec/blob/master/spec.md)
|
||||
(CSI) moves to beta in this release: installing new volume plugins is now as
|
||||
easy as deploying a pod. This in turn enables third-party storage providers to
|
||||
develop their solutions independently outside of the core Kubernetes codebase.
|
||||
This continues the thread of extensibility within the Kubernetes ecosystem.
|
||||
|
||||
[Durable (non-shared) local storage
|
||||
management](https://github.com/kubernetes/features/issues/121) progressed to
|
||||
beta in this release, making locally attached (non-network attached) storage
|
||||
available as a persistent volume source. This means higher performance and
|
||||
lower cost for distributed file systems and databases.
|
||||
|
||||
This release also includes many updates to Persistent Volumes. Kubernetes can
|
||||
automatically [prevent deletion of Persistent Volume Claims that are in use by
|
||||
a pod](https://github.com/kubernetes/features/issues/498) (beta) and [prevent
|
||||
deletion of a Persistent Volume that is bound to a Persistent Volume Claim
|
||||
](https://github.com/kubernetes/features/issues/499)(beta). This helps ensure
|
||||
that storage API objects are deleted in the correct order.
|
||||
|
||||
## Security - External credential providers (alpha)
|
||||
|
||||
Kubernetes, which is
|
||||
already highly extensible, gains another extension point in 1.10 with
|
||||
[external kubectl credential
|
||||
providers](https://github.com/kubernetes/features/issues/541) (alpha). Cloud
|
||||
providers, vendors, and other platform developers can now release binary
|
||||
plugins to handle authentication for specific cloud-provider IAM services, or
|
||||
that integrate with in-house authentication systems that aren’t supported
|
||||
in-tree, such as Active Directory. This complements the [Cloud Controller
|
||||
Manager](https://kubernetes.io/docs/tasks/administer-cluster/running-cloud-controller/)
|
||||
feature added in 1.9.
|
||||
|
||||
## Networking - CoreDNS as a DNS provider (beta)
|
||||
|
||||
The ability to [switch the DNS
|
||||
service](https://github.com/kubernetes/website/pull/7638) to CoreDNS at
|
||||
[install time](https://kubernetes.io/docs/tasks/administer-cluster/coredns/)
|
||||
is now in beta. CoreDNS has fewer moving parts: it’s a single executable and a
|
||||
single process, and supports additional use cases.
|
||||
|
||||
Each Special Interest Group (SIG) within the community continues to deliver
|
||||
the most-requested enhancements, fixes, and functionality for their respective
|
||||
specialty areas. For a complete list of inclusions by SIG, please visit the
|
||||
[release
|
||||
notes](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.10.md#110-release-notes).
|
||||
|
||||

|
||||
## Release team
|
||||
|
||||
This release is made possible through the effort of hundreds of
|
||||
individuals who contributed both technical and non-technical content. Special
|
||||
thanks to the [release
|
||||
team](https://github.com/kubernetes/sig-release/blob/master/releases/release-1.10/release_team.md)
|
||||
led by Jaice Singer DuMars, Kubernetes Ambassador for Microsoft. The 10
|
||||
individuals on the release team coordinate many aspects of the release, from
|
||||
documentation to testing, validation, and feature completeness.
|
||||
|
||||
As the Kubernetes community has grown, our release process represents an
|
||||
amazing demonstration of collaboration in open source software development.
|
||||
Kubernetes continues to gain new users at a rapid clip. This growth creates a
|
||||
positive feedback cycle where more contributors commit code creating a more
|
||||
vibrant ecosystem.
|
||||
|
||||
## Project Velocity
|
||||
|
||||
The CNCF has continued refining an ambitious project to
|
||||
visualize the myriad contributions that go into the project. [K8s
|
||||
DevStats](https://devstats.k8s.io/) illustrates the breakdown of contributions
|
||||
from major company contributors, as well as an impressive set of preconfigured
|
||||
reports on everything from individual contributors to pull request lifecycle
|
||||
times. Thanks to increased automation, issue count at the end of the release
|
||||
was only slightly higher than it was at the beginning. This marks a major
|
||||
shift toward issue manageability. With 75,000+ comments, Kubernetes remains
|
||||
one of the most actively discussed projects on GitHub.
|
||||
|
||||
## User Highlights
|
||||
|
||||
According to a [recent CNCF
|
||||
survey](https://www.cncf.io/blog/2018/03/26/cncf-survey-china/), more than 49%
|
||||
of Asia-based respondents use Kubernetes in production, with another 49%
|
||||
evaluating it for use in production. Established, global organizations are
|
||||
using [Kubernetes in production](https://kubernetes.io/case-studies/) at
|
||||
massive scale. Recently published user stories from the community include:
|
||||
1. **Huawei**, the largest telecommunications equipment manufacturer in the
|
||||
world, [moved its internal IT department’s applications to run on
|
||||
Kubernetes](https://kubernetes.io/case-studies/huawei/). This resulted in the
|
||||
global deployment cycles decreasing from a week to minutes, and the efficiency
|
||||
of application delivery improved by tenfold.
|
||||
1. **Jinjiang Travel International**, one of the top 5 largest OTA and hotel
|
||||
companies, use Kubernetes to [speed up their software release
|
||||
velocity](https://www.linux.com/blog/managing-production-systems-kubernetes-chinese-enterprises)
|
||||
from hours to just minutes. Additionally, they leverage Kubernetes to increase
|
||||
the scalability and availability of their online workloads.
|
||||
1. **Haufe Group**, the Germany-based media and software company, utilized
|
||||
Kubernetes to [deliver a new release in half an
|
||||
hour](https://kubernetes.io/case-studies/haufegroup/) instead of days. The
|
||||
company is also able to scale down to around half the capacity at night,
|
||||
saving 30 percent on hardware costs.
|
||||
1. **BlackRock**, the world’s largest asset manager, was able to move quickly
|
||||
using Kubernetes and built an investor research web app from [inception to
|
||||
delivery in under 100 days](https://kubernetes.io/case-studies/blackrock/).

with the community.
|
||||
|
||||
## Ecosystem Updates
|
||||
|
||||
1. The CNCF is expanding its certification offerings to
|
||||
include a Certified Kubernetes Application Developer exam. The CKAD exam
|
||||
certifies an individual's ability to design, build, configure, and expose
|
||||
cloud native applications for Kubernetes. The CNCF is looking for beta testers
|
||||
for this new program. More information can be found
|
||||
[here](https://www.cncf.io/blog/2018/03/16/cncf-announces-ckad-exam/).
|
||||
1. Kubernetes documentation now features [user
|
||||
journeys](https://k8s.io/docs/home/): specific pathways for learning based on
|
||||
who readers are and what readers want to do. Learning Kubernetes is easier
|
||||
than ever for beginners, and more experienced users can find task journeys
|
||||
specific to cluster admins and application developers.
|
||||
1. CNCF also offers [online
|
||||
training](https://www.cncf.io/certification/training/) that teaches the skills
|
||||
needed to create and configure a real-world Kubernetes cluster.
|
||||
|
||||
