Install OpenShift
The qubinode-installer
Download and extract the qubinode-installer as a non root user.
cd $HOME
wget https://github.com/Qubinode/qubinode-installer/archive/master.zip
unzip master.zip
rm master.zip
mv qubinode-installer-master qubinode-installer
Place your pull secret and the rhel qcow image under the qubinode-installer directory.
If you are using tokens it should be:
* $HOME/qubinode-installer/ocp_token
* $HOME/qubinode-installer/rhsm_token
If you downloaded the files instead it should be:
* $HOME/qubinode-installer/pull-secret.txt
* $HOME/qubinode-installer/rhel-server-7.8-x86_64-kvm.qcow2
* $HOME/qubinode-installer/rhel-8.2-x86_64-kvm.qcow2
Install Options
Choose one of the below options. The quick start is ideal if you meet your resource requirements documented in our hardware guide. The advanced option will provide the most flexibilty as you can decide which modules you want to execute and also customize your OCP4 cluster size.
| Standard Deployment | Custom Deployment |
|---|---|
| Answer questions from the installer to deploy a 6 node OpenShift 4.x cluster, 3 controlplane and 3 computes. | This option will allow you to deploy a 3 only or 4 node cluster or to customize the size of the cluster. |
