# Red Hat OpenShift Container Platform Cluster deployment

This section describes the process to deploy Red Hat OpenShift Container Platform 4.

Pre-requisites

Bootstrap node should be up.
Master nodes should be up and ready.

# Deploying an OpenShift cluster

This section covers the steps to deploy a Red Hat OpenShift Container Platform 4 cluster with master nodes and worker nodes running RHCOS. After the operating system is installed on the nodes, verify the installation and then perform the following steps:

Execute the following command to bootstrap the nodes.

> $BASE_DIR/installer/library/openshift_components/openshift-install wait-for bootstrap-complete --log-level=debug

RESULT

DEBUG OpenShift Installer v4.6

DEBUG Built from commit 425e4ff0037487e32571258640b39f56d5ee5572

INFO Waiting up to 30m0s for the Kubernetes API at https://api.ocp.pxelocal.local:6443...

INFO API v1.14.6+76aeb0c up

INFO Waiting up to 30m0s for bootstrapping to complete...

DEBUG Bootstrap status: complete

INFO It is now safe to remove the bootstrap resources

NOTE

You can shut down or remove the bootstrap node after the completion of step 1 and step 2.

Run the following command to append the kubeconfig path to environment variables.
```
> export KUBECONFIG=$BASE_DIR/installer/ignitions/auth/kubeconfig
```
Run the following command to append the oc utility path to environment variables.
```
> export PATH=$PATH:$BASE_DIR/installer/library/openshift_components
```

Provide the PV storage for the registry. Execute the following command to set the image registry storage to an empty directory.

> oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"storage":{"emptyDir":{}}}}'

Execute the following command to complete the RedHat OpenShift Container Platform 4 cluster installation.

> $BASE_DIR/installer/library/openshift_components/openshift-install wait-for install-complete --log-level=debug

The result should appear like what appears below.

INFO Login to the console with user: kubeadmin, password: a6hKv-okLUA-Q9p3q-UXLc3

NOTE

Make a note of the cluster URL and the username for future access.

If the password is lost or forgotten, view the file kubeadmin-password located in the installer machine at $BASE_DIR/installer/library/ignitions/auth/.
