Patrick Ohly fc3ee07b51 e2e pods: fix WaitForPodsResponding retry
The status error was embedded inside the new error constructed by
WaitForPodsResponding's get function, but not wrapped. Therefore
`apierrors.IsServiceUnavailable(err)` didn't find it and returned false -> no
retries.

Wrapping fixes this and Gomega formatting of the error remains useful:

	err := &errors.StatusError{}
	err.ErrStatus.Code = 503
	err.ErrStatus.Message = "temporary failure"

	err2 := fmt.Errorf("Controller %s: failed to Get from replica pod %s:\n%w\nPod status:\n%s",
		"foo", "bar",
		err, "some status")
	fmt.Println(format.Object(err2, 1))
        fmt.Println(errors.IsServiceUnavailable(err2))

=>

    <*fmt.wrapError | 0xc000139340>:
    Controller foo: failed to Get from replica pod bar:
    temporary failure
    Pod status:
    some status
    {
        msg: "Controller foo: failed to Get from replica pod bar:\ntemporary failure\nPod status:\nsome status",
        err: <*errors.StatusError | 0xc0001a01e0>{
            ErrStatus: {

                    RemainingItemCount: nil,
                },
                Status: "",
                Message: "temporary failure",
                Reason: "",

Kubernetes (K8s)

CII Best Practices Go Report Card GitHub release (latest SemVer)


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

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 the 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.
