Container-native Virtualization (CNV) Red Hat Summit Demo 2018

This repository contains a setup which is pretty close to the demo seen at Red Hat Summit 2018.

This includes the eventually modified components:

• KubeVirt
• Client tools
• VM Template
• OpenShift Web Console

This does not include:

• CDI - Due to issues to deploy it robust in a generic setup This script also sets up the CDI, but is not as robust.
• Metrics - Unstable to deploy

Requirements

• OpenShift Client Tool v3.9.0 installed
• oc cluster up configured
• virtctl v0.4.1 installed

Usage

Note: Take a look at the .logs file in case of an error or use tail -f .logs during deployment to view the status.

Note: The required setup time is heavily depending on the speed of your internet connection.

The oc-cnv script does all necessary steps, you can pass the -v flag to see all the relevant calls done to perform the setup.

>     oc login -u system:admin

INFO For CNV: Log into the web console as 'developer' and go to https://127.0.0.1:8443/console/project/myproject/overview
$

Note: Once setup, the virtual machines and templates are accessible in the project My Project

virtctl

In order to start, stop, and connect to a virtual machine console you can use the virtctl tool:

# Important: Login as admin (a known issue)
$ oc login -u system:admin
$ ./virtctl-v0.4.1-linux-amd64 start testvm
$ ./virtctl-v0.4.1-linux-amd64 vnc testvm
$ ./virtctl-v0.4.1-linux-amd64 stop testvm

CLI

The provided template can also be used to instantiate a new virtual machine from the CLI using:

$ oc login -u developer
Logged into "https://127.0.0.1:8443" as "developer" using existing credentials.
...
Using project "myproject".
$ oc new-app --template cirros-vm-template -p NAME=second
--> Deploying template "myproject/cirros-vm-template" to project myproject

     CirrOS Virtual Machine
     ---------
     OCP KubeVirt CirrOS VM template

     * With parameters:
        * NAME=second
        * MEMORY=512Mi
        * CPU_CORES=2

--> Creating resources ...
    offlinevirtualmachine "second" created
--> Success
    Run 'oc status' to view your app.

User Guide

Once started, thre is the KubeVirt user guide to work with the new entities.

Cleanup

Note: This will remove all oc cluster related data.

The setup can be cleaned using:

$ ./oc-cnv clean
