Install an OpenShift cluster

Openshift Installer

Supported Platforms

• AWS
• Libvirt with KVM
• OpenStack (Experimental)

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 requires the terraform binary either alongside openshift-install or in $PATH. If you don't have terraform, run the following to create bin/terraform:

hack/get-terraform.sh

The installer will show a series of prompts for user-specific information (e.g. admin password) and use reasonable defaults for everything else. In non-interactive contexts, prompts can be bypassed by providing appropriately-named environment variables. Refer to the user documentation for more information.

Connect to the cluster

Console

Shortly after the cluster command completes, the OpenShift console will come up at https://${OPENSHIFT_INSTALL_CLUSTER_NAME}-api.${OPENSHIFT_INSTALL_BASE_DOMAIN}:6443/console/. You may need to ignore a certificate warning if you did not configure a certificate authority known to your browser. Log in using the admin credentials you configured when creating the cluster.

Kubeconfig

You can also use the admin kubeconfig which openshift-install create cluster placed under --dir (which defaults to .) in auth/kubeconfig. If you launched the cluster with openshift-install --dir "${DIR}" create cluster, you can use:

export KUBECONFIG="${DIR}/auth/kubeconfig"

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.
