Miciah Masters 5832b84200 kubelet: parseResolvConf: Handle "search ."
When parsing a resolv.conf file that has "search .", parseResolvConf should
accept the "." entry verbatim.  Before this commit, parseResolvConf
unconditionally trimmed the "." suffix, which in the case of "." resulted
in a "" entry (that is, the empty string).  This empty entry could lead
parseResolvConf to produce a resolv.conf file with "search ".  Resolvers
could fail to parse such a resolv.conf file from parseResolvConf, thus
breaking DNS resolution in pods.  After this commit, parseResolvConf
accepts a resolv.conf file with "search ." and passes the "." entry through
verbatim to produce a valid resolv.conf file.  The "." suffix is still
trimmed for any entry that does not solely comprise ".".

Follow-up to commit a215a88d91.

* pkg/kubelet/network/dns/dns.go (parseResolvConf): Handle a "." entry in
the search path by copying it verbatim.
* pkg/kubelet/network/dns/dns_test.go (TestParseResolvConf): Add a test
case for "search .".

Kubernetes (K8s)

GoPkg Widget CII Best Practices


Kubernetes, also known as K8s, is an open source system for managing containerized applications across multiple hosts. It provides 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 your company 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 K8s

See our documentation on kubernetes.io.

Try our interactive tutorial.

Take a free course on Scalable Microservices with Kubernetes.

To use Kubernetes code as a library in other applications, see the list of published components. Use of the k8s.io/kubernetes module or k8s.io/kubernetes/... packages as libraries is not supported.

To start developing K8s

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.
mkdir -p $GOPATH/src/k8s.io
cd $GOPATH/src/k8s.io
git clone https://github.com/kubernetes/kubernetes
cd 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.

Community Meetings

The Calendar has the list of all the meetings in Kubernetes community in a single location.

Adopters

The User Case Studies website has real-world use cases of organizations across industries that are deploying/migrating to Kubernetes.

Governance

Kubernetes project is governed by a framework of principles, values, policies and processes to help our community and constituents towards our shared goals.

The Kubernetes Community is the launching point for learning about how we organize ourselves.

The Kubernetes Steering community repo is used by the Kubernetes Steering Committee, which oversees governance of the Kubernetes project.

Roadmap

The Kubernetes Enhancements repo provides information about Kubernetes releases, as well as feature tracking and backlogs.
