Audio quality is highly dependent on individual’s internet bandwidth. If you experience audio issues, we recommend you :

1) Turn off your company VPN connection2) Check if you have applications running in the background –

anti-virus can completely cut audio3) If your computer is connected to a virtual environment, it

can effect quality – connect from a PC w/out virtual environment if possible

Red Hat OpenShift Container change – Docker

Red Hat headed towards a world without Docker

• cri-o is only one component (the Kubernetes CRI runtime) of OpenShift

• RHEL will not deliver a Docker engine anymore

• Red Hat replaced it with:

– podman (Docker client compatible CLI)

– skopeo (registry)

– buildah (Docker build)

Introduction to RHEL CoreOS (RHCOS)

Immutable container host based on RHEL 8

• CoreOS is tested and shipped in conjunction with the Red Hat OpenShift platform

• Immutable – can not be changed & no sshand tightly integrated with Red Hat OpenShift

• Self-managing, over-the-air updates, appliance model – like a container

• Host isolation is enforced via Containers and Security Enhanced Linux (SELinux)

CoreOS is operated as part of the cluster with config for components managed by operators.

OpenShift on IBM Z and LinuxONE

Basic installation steps:⚫ Prepare your z/VM environment ( User directories, storage, network ) ⚫ Prepare a RHEL 8.1 Bootstrap (temporary ) server

⚫ Setup an FTP or HTTP server to serve installation files⚫ Prepare the OCP pre-req. Services: DNS, NFS, Load Balancer, DHCP⚫ Download OCP product code from cloud.redhat.com:

⚫ openshift-installer, RH CoreOS image ⚫ Run the openshift-installer to define and create ignition files for the OpenShift cluster⚫ Save the ignition files on the FTP / HTTP server⚫ Copy kernel image, parmfile, coreos-installer image to your z/VM guests⚫ Adjust the parmfile for the z/VM guest

and specify the ignition file for the bootstrap, master, and worker nodes⚫ Punch the installation files into the z/VM virtual readers⚫ Boot (IPL from z/VM virtual reader) the CoreOS-installer

on each node, to install the bootstrap, master, and worker nodes
