- Have access to an Amazon Web Services account with permissions to be able to create resources including ~s3~ buckets and ~ec2~ instances. In my case I have an AWS Blank Open Environment provisioned through the Red Hat [[https://demo.redhat.com][demo system]].
- Already have the ~aws~ and ~oc~ cli utilities installed.
- Have registered for a Red Hat account (required for obtaining an OpenShift install image pull secret).

* 3 - Install openshift clusters
With our aws credentials working let's move on to deploying the hub and single node openshift cluster required for the live demo.
** 3.1 Download installer tools
Our first step will be to ensure we have the ~openshift-install~ cli tool. We can download it as follows:
#+begin_src tmux
# Download the installer
wget "https://mirror.openshift.com/pub/openshift-v4/$(uname -m)/clients/ocp/stable/openshift-install-linux.tar.gz"
# Extract the archive
tar xf openshift-install-linux.tar.gz
#+end_src
** 3.2 Obtain install pull secret
Next we have a manual step to login to the Red Hat Hybrid Cloud Console and obtain our **Pull Secret** which will be required for our installation configuration.
Open the [[https://console.redhat.com/openshift/create/local][Console]] and click **Download pull secret**. This will download a file called ~pull-secret.txt~ which will be used later on.
** 3.3 Initiate the hub cluster install
Once our install tooling is available let's kick off the installation of our hub cluster by creating a configuration file and then running ~openshift-install~.
