OpenShift Container Platform 4.6 on Synergy

# Red Hat OpenShift Container Platform Cluster deployment

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

PREREQUISITES

  • 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:

  1. Login to the installer VM as non-root user.

  2. 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.

  1. Run the following command to append the kubeconfig path to environment variables.

    >  export KUBECONFIG=$BASE_DIR/installer/ignitions/auth/kubeconfig

  2. Run the following command to append the oc utility path to environment variables.

    > export PATH=$PATH:$BASE_DIR/installer/library/openshift_components

  3. 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":{}}}}'

  4. 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 To access the cluster as the system:admin user when using 'oc', run 'export KUBECONFIG=/opt/hpe/solutions/ocp/hpe-solutions-openshift/synergy/scalable/installer/library/ignitions/auth/kubeconfig' 

INFO Access the OpenShift web-console here: https://console-openshift-console.apps.ocp.pxelocal.local 

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/.*
