The previous approach with grabbing via a nginx proxy had some drawbacks: - it did not work when the pods only listened on localhost (as configured by kubeadm) and the proxy got deployed on a different node - starting the proxy raced with starting the pods, causing sporadic test failures because the proxy was not set up properly unless it saw all pods when starting the e2e.test - the proxy was always started, whether it is needed or not - the proxy was left running after a test and then the next test run triggered potentially confusing messages when it failed to create objects for the proxy The new approach is similar to "kubectl port-forward" + "kubectl get --raw". It uses the port forwarding feature to establish a TCP connection via a custom dialer, then lets client-go handle TLS and credentials. Somehow verifying the server certificate did not work. As this shouldn't be a big concern for E2E testing, certificate checking gets disabled on the client side instead of investigating this further.
Kubernetes (K8s)
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.
