Kubernetes Operations (kops)

The easiest way to get a production grade Kubernetes cluster up and running.

What is kops?

We like to think of it as kubectl for clusters.

kops lets you deploy production-grade, highly available, Kubernetes clusters from the command line. Deployment is currently supported on Amazon Web Services (AWS), with more platforms planned.

Can I see it in action?

Launching a Kubernetes cluster hosted on AWS

To replicate the above demo, check out our tutorial for launching a Kubernetes cluster hosted on AWS.

Features

• Automate the provisioning of Kubernetes clusters in (AWS)
• Deploy Highly Available (HA) Kubernetes Masters
• Supports upgrading from kube-up
• Built on a state-sync model for dry-runs and automatic idempotency
• Ability to generate Terraform configuration
• Supports custom add-ons for kubectl
• Command line autocompletion
• Community supported!

Installing

kubectl is required, see here.

OSX From Homebrew (Latest Stable Release)

$ brew update && brew install kops

OSX From Homebrew (HEAD of master)

Linux

Download the latest release, then:

$ chmod +x kops-linux-amd64                 # Add execution permissions
$ mv kops-linux-amd64 /usr/local/bin/kops   # Move the kops to /usr/local/bin

From Source

Go 1.7+ and make are required.

$ go get -d k8s.io/kops

Getting involved!

Want to contribute to kops? We would love the extra help from the community. We have a quickstart guide on adding a feature.

Kops also has time set aside every other week to offer help and guidance to the community. Kops maintainers have agreed to set aside time specifically dedicated to working with newcomers, helping with PRs, and discussing new features.

We recommend letting us know beforehand if you plan on attending so we can have time to prepare for the call.

• Open a new issue
• Remember users might be searching for your issue in the future, so please give it a meaningful title to helps others.
• Clearly define the use case, using concrete examples. EG: I type this and kops does that.
• Some of our larger features will require some design. If you would like to include a technical design for your feature please include it in the issue.
• After the new feature is well understood, and the design agreed upon we can start coding the feature. We would love for you to code it. So please open up a WIP (work in progress) pull request, and happy coding.
