We have 2 scenarios where we copy /etc/hosts
- with host network (we just copy the /etc/hosts from node)
- without host network (create a fresh /etc/hosts from pod info)
We are having trouble figuring out whether a /etc/hosts in a
pod/container has been "fixed-up" or not. And whether we used
host network or a fresh /etc/hosts in the various ways we start
up the tests which are:
- VM/box against a remote cluster
- As a container inside the k8s cluster
- DIND scenario in CI where test runs inside a managed container
Please see previous mis-guided attempt to fix this problem at
ba20e63446 In this commit we revert
the code from there as well.
So we should make sure:
- we always add a header if we touched the file
- we add slightly different headers so we can figure out if we used the
host network or not.
Update the test case to inject /etc/hosts from node to another path
(/etc/hosts-original) as well and use that to compare.
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.
