Configuring and deploying the dataplane

Assumptions

Initialize

Switch to the "openstack" namespace

oc project openstack

Change to the nova/nova04delta directory

cd architecture/examples/dt/nova/nova04delta

Edit the edpm/nodeset/values.yaml file to suit your environment.

vi edpm/nodeset/values.yaml

In nodeset/values.yaml, pay special attention to the baremetalhosts section. You will need to provide details for each of your baremetal compute nodes, including:

  • bmc.address: The IP address of the Baseboard Management Controller (BMC).
  • bootMACAddress: The MAC address of the network interface that the node will use to PXE boot.
  • Other parameters as described in the main README.md.

Additionally, you need to provide SSH keys for Nova live migration. The following keys in edpm/nodeset/values.yaml must be populated with base64 encoded values:

  • nova.migration.ssh_keys.private
  • nova.migration.ssh_keys.public

You can encode your keys using the base64 command, for example: cat ~/.ssh/id_rsa | base64 -w0.


### Create the BareMetalHost CRs

Also, ensure the `bmhLabelSelector` in `baremetalSetTemplate` matches the labels you have defined for your `baremetalhosts`. For example, if you use `app: openstack`, your `baremetalhosts` should have a corresponding label.

Before applying the nodeset configuration, you must also create the `bmc-secret` secret that contains the BMC credentials. You can create it with the following command:

oc create secret generic bmc-secret --from-literal=username=CHANGEME --from-literal=password=CHANGEME


Generate the dataplane nodeset CR, which includes the BareMetalHost definitions.

kustomize build nodeset > dataplane-nodeset.yaml


Apply the CR to create the BareMetalHost and the nodeset.

oc apply -f dataplane-nodeset.yaml


Wait for the BareMetalHosts to become available. You can monitor the status with:

oc get bmh -w

The state should change to `available`.

### Configure and deploy the dataplane

Edit `edpm/deployment/values.yaml` if needed.

vi edpm/deployment/values.yaml


Build it with kustomize.

kustomize build deployment > dataplane-deployment.yaml


Wait for dataplane nodeset setup to finish.

oc wait osdpns openstack-edpm --for condition=SetupReady --timeout=600s


Start the deployment

oc apply -f dataplane-deployment.yaml


Wait for dataplane deployment to finish

oc wait osdpd edpm-deployment --for condition=Ready --timeout=40m


After the Nvidia drivers have been blacklisted on the EDPM nodes, and kernel args updated, edpm hosts will be
automatically rebooted.
