KNI Installer

kni-install is a forked version of openshift-install that serves as a staging area for a new 'baremetal' platform that is intended to eventually be merged into openshift-install itself.

The 'baremetal' platform support will ultimately be implemented using libvirt for the bootstrap VM and the MetalKube baremetal-operator for the masters and workers. However, many hacky short-cuts may used in the interim as the support it prototyped!

The facet project is a closely related project that provides a "day 1" UI (served by a REST API) which gathers information from the user about the cluster configuration and bare metal hosts, before using kni-install to provision the cluster.

Supported Platforms

Quick Start

First, install all build dependencies.

Clone this repository to src/github.com/openshift-metalkube/kni-installer in your GOPATH. Then build the kni-install binary with:

hack/build.sh

This will create bin/kni-install. This binary can then be invoked to create an OpenShift cluster, like so:

bin/kni-install create cluster

The installer will show a series of prompts for user-specific information and use reasonable defaults for everything else. In non-interactive contexts, prompts can be bypassed by providing an install-config.yaml.

If you have trouble, refer to the troubleshooting guide.

Connect to the cluster

Details for connecting to your new cluster are printed by the kni-install binary upon completion, and are also available in the .openshift_install.log file.

Example output:

INFO Waiting 10m0s for the openshift-console route to be created...
INFO Install complete!
INFO To access the cluster as the system:admin user when using 'oc', run 'export KUBECONFIG=/path/to/installer/auth/kubeconfig'
INFO Access the OpenShift web-console here: https://console-openshift-console.apps.${CLUSTER_NAME}.${BASE_DOMAIN}:6443
INFO Login to the console with user: kubeadmin, password: 5char-5char-5char-5char

Cleanup

Destroy the cluster and release associated resources with:

kni-install destroy cluster

Note that you almost certainly also want to clean up the installer state files too, including auth/, terraform.tfstate, etc. The best thing to do is always pass the --dir argument to install and destroy. And if you want to reinstall from scratch, rm -rf the asset directory beforehand.
