"KubeletManagedEtcHosts should test kubelet managed /etc/hosts file" conformance test fails in the CI's Docker-In-Docker environment. This test mounts a /etc/hosts file and checks if "# Kubernetes-managed hosts file." string is present or not under various conditions. The specific failure with DIND happens when the /etc/hosts picked up from the box where e2e test are running already has this string. This happens because our CI runs on kubernetes and the e2e tests are running in a container that was started on kubernetes (and hence already has that string) To avoid this situation, we create a new /etc/hosts file with known contents (and does not have the "# Kubernetes-managed hosts file." string)
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.
