Configure the Dataplane Network

  1. Using a preconfigured yaml file(files/osp-ng-dataplane-netconfig.yaml) we will configure the topology for each data plane network.

If needed cd to files:

cd dp-demo/demo/files

Apply the network confguration:

oc apply -f osp-ng-dataplane-netconfig.yaml

Create VM for Dataplane

Go to https://access.redhat.com/downloads/content/479/ver=/rhel---9/9.3/x86_64/product-software and login. Scroll down to Red Hat Enterprise Linux 9.3 KVM Guest Image and copy the link and replace rhellink below. Keep the double quotes, otherwise the download will fail.

  1. Download the RHEL image on lab-user(hypervisor) server:
sudo -i
cd /var/lib/libvirt/images
curl -o rhel9-3.qcow2 "rhellink"

cp rhel9-3.qcow2 rhel9-guest.qcow2
qemu-img info rhel9-guest.qcow2
qemu-img resize rhel9-guest.qcow2 +90G
chown -R qemu:qemu rhel9-*.qcow2
virt-customize -a rhel9-guest.qcow2 --run-command 'growpart /dev/sda 4'
virt-customize -a rhel9-guest.qcow2 --run-command 'xfs_growfs /'
virt-customize -a rhel9-guest.qcow2 --root-password password:redhat
virt-customize -a rhel9-guest.qcow2 --run-command 'systemctl disable cloud-init'
virt-customize -a /var/lib/libvirt/images/rhel9-guest.qcow2 --ssh-inject root:file:/root/.ssh/id_rsa.pub
virt-customize -a /var/lib/libvirt/images/rhel9-guest.qcow2 --selinux-relabel
qemu-img create -f qcow2 -F qcow2 -b /var/lib/libvirt/images/rhel9-guest.qcow2 /var/lib/libvirt/images/osp-compute-0.qcow2
virt-install --virt-type kvm --ram 16384 --vcpus 4 --cpu=host-passthrough --os-variant rhel8.4 --disk path=/var/lib/libvirt/images/osp-compute-0.qcow2,device=disk,bus=virtio,format=qcow2 --network network:ocp4-provisioning --network network:ocp4-net --boot hd,network --noautoconsole --vnc --name osp-compute0 --noreboot
virsh start osp-compute0

Login to the Compute and verify

  1. Verify IP from 192.168.123.0/24
watch virsh domifaddr osp-compute0 --source agent

(control + C to continue)

virsh domifaddr osp-compute0 --source agent

ssh to the IP assigned

ssh root@192.168.123.61

Install certificates for registry

Replace uuid

ex +'/BEGIN CERTIFICATE/,/END CERTIFICATE/p' <(echo | openssl s_client -showcerts -connect quay.apps.uuid.dynamic.redhatworkshops.io:443) -scq > server.pem
sudo cp server.pem /etc/pki/ca-trust/source/anchors/
sudo cp server.pem /etc/pki/tls/certs/
sudo update-ca-trust

Configure ethernet devices

nmcli co delete 'Wired connection 1'
nmcli con add con-name "static-eth0" ifname eth0 type ethernet ip4 172.22.0.100/24 ipv4.dns "172.22.0.89"
nmcli con up "static-eth0"
nmcli co delete 'Wired connection 2'
nmcli con add con-name "static-eth1" ifname eth1 type ethernet ip4 192.168.123.61/24 ipv4.dns "192.168.123.100" ipv4.gateway "192.168.123.1"
nmcli con up "static-eth1"

cat >> /etc/resolv.conf <<EOF
# Generated by NetworkManager
search aio.example.com
nameserver 172.22.0.89
EOF

And log off VM

logout

Log into the compute server, set hostname, and subscribe it with a validated account

ssh root@172.22.0.100
sudo hostnamectl set-hostname edpm-compute-0.aio.example.com
subscription-manager register

Configure for the RHEL 9.3 Repos

sudo subscription-manager repos --disable=*
subscription-manager repos --enable=rhceph-6-tools-for-rhel-9-x86_64-rpms --enable=rhel-9-for-x86_64-baseos-rpms --enable=rhel-9-for-x86_64-appstream-rpms --enable=rhel-9-for-x86_64-highavailability-rpms --enable=openstack-17.1-for-rhel-9-x86_64-rpms --enable=fast-datapath-for-rhel-9-x86_64-rpms
sudo subscription-manager release --set=9.3

Install podman on the compute and login to registries

sudo dnf install -y podman

podman login registry.redhat.io

podman login  --username "quay_user" --password "openstack" quay.apps.uuid.dynamic.redhatworkshops.io/quay_user/dp3-openstack-operator-index

Log off

logout

Snapshot the Compute

virsh snapshot-create-as osp-compute0 preprovisioned

Set SSH key

scp /root/.ssh/id_rsa root@192.168.123.100:/root/.ssh/id_rsa_compute
scp /root/.ssh/id_rsa.pub root@192.168.123.100:/root/.ssh/id_rsa_compute.pub

Create a secret for the dataplane

  1. Back on the bastion server:
oc create secret generic dataplane-ansible-ssh-private-key-secret --save-config --dry-run=client --from-file=authorized_keys=/root/.ssh/id_rsa_compute.pub --from-file=ssh-privatekey=/root/.ssh/id_rsa_compute --from-file=ssh-publickey=/root/.ssh/id_rsa_compute.pub -n openstack -o yaml | oc apply -f-
ssh-keygen -f ./id -t ecdsa-sha2-nistp521 -N ''
oc create secret generic nova-migration-ssh-key --from-file=ssh-privatekey=id --from-file=ssh-publickey=id.pub -n openstack -o yaml | oc apply -f-
  1. Deploy the Dataplane

Replace uuid in osp-ng-dataplane-node-set-deploy.yaml and apply

oc apply -f osp-ng-dataplane-node-set-deploy.yaml
oc apply -f osp-ng-dataplane-deployment.yaml
