Install an OpenShift 4.x cluster

OpenShift Installer

Supported Platforms

Quick Start

First, install all build dependencies.

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

hack/build.sh

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

bin/openshift-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 openshift-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:

openshift-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.
