concourse.ci on kubernetes via minikube

README.md

This is a work in progress and gets you to a running state (meaning you can bring the UI up via brower and login). It is not however fully tested.

To generate your keys, see https://concourse.ci/docker-repository.html and https://concourse.ci/binaries.html for notes on getting started.

Also see https://github.com/kubernetes/minikube/releases/tag/v0.12.1 for notes regarding minikube.

In this example, minikube was run on OSX sierra with v0.12.1 and xhyve hypervisor.

Minikube cluster created with minikube start --vm-driver=xhyve
