Red Hat build of MicroShift

Create a virtual machine

You can create a virtual machine by using the Red Hat Enterprise Linux (RHEL) boot ISO image.

Prerequisites

You created the Kickstart file.
You installed the OpenShift CLI (oc).
You have redhat credentials.

Procedure

Download the Red Hat Enterprise Linux (RHEL) boot ISO image from the Download Red Hat Enterprise Linux.
Copy the downloaded file to the /var/lib/libvirt/images directory.
Configure the VMNAME environment variable with your value by running the following command:
```
$ VMNAME=microshift-4.20-bootc
```
Configure the NETNAME environment variable with your value by running the following command:
```
$ NETNAME=default
```

Create a RHEL virtual machine with 2 cores, 2GB of RAM and 20GB of storage by running the following command:

$ sudo virt-install \
    --name ${VMNAME} \
    --vcpus 2 \
    --memory 2048 \
    --disk path=/var/lib/libvirt/images/${VMNAME}.qcow2,size=20 \
    --network network=${NETNAME},model=virtio \
    --events on_reboot=restart \
    --location /var/lib/libvirt/images/rhel-9.6-$(uname -m)-boot.iso \
    --initrd-inject kickstart.ks \
    --extra-args "inst.ks=file://kickstart.ks" \
    --wait

The sudo virt-install command uses the Kickstart file to pull a bootc image from the remote registry and install the RHEL operating system.

Verification

Verify that all of the MicroShift pods are running without error by entering the following command:

$ watch sudo oc get pods -A \
    --kubeconfig /var/lib/microshift/resources/kubeadmin/kubeconfig
