Install StarlingX Kubernetes on Virtual Standard with Rook Storage

This section describes the steps to install the StarlingX Kubernetes platform on a StarlingX R5.0 virtual Standard with Rook Storage deployment configuration, deploy rook ceph cluster replacing default native ceph cluster.

Install software on controller-0

In the last step of rook_storage_environ, the controller-0 virtual server 'rookstorage-controller-0' was started by the setup_configuration.sh command.

On the host, attach to the console of virtual controller-0 and select the appropriate installer menu options to start the non-interactive install of StarlingX software on controller-0.

Note

When entering the console, it is very easy to miss the first installer menu selection. Use ESC to navigate to previous menus, to ensure you are at the first installer menu.

virsh console rookstorage-controller-0

Make the following menu selections in the installer:

First menu: Select 'Standard Controller Configuration'
Second menu: Select 'Serial Console'

Wait for the non-interactive install of software to complete and for the server to reboot. This can take 5-10 minutes depending on the performance of the host machine.

Bootstrap system on controller-0

Configure controller-0

On virtual controller-0:

Acquire admin credentials:
```
source /etc/platform/openrc
```

Configure the OAM and MGMT interfaces of controller-0 and specify the attached networks:

OAM_IF=enp7s1
MGMT_IF=enp7s2
system host-if-modify controller-0 lo -c none
IFNET_UUIDS=$(system interface-network-list controller-0 | awk '{if ($6=="lo") print $4;}')
for UUID in $IFNET_UUIDS; do
    system interface-network-remove ${UUID}
done
system host-if-modify controller-0 $OAM_IF -c platform
system interface-network-assign controller-0 $OAM_IF oam
system host-if-modify controller-0 $MGMT_IF -c platform
system interface-network-assign controller-0 $MGMT_IF mgmt
system interface-network-assign controller-0 $MGMT_IF cluster-host

Configure NTP servers for network time synchronization:

Note

In a virtual environment, this can sometimes cause Ceph clock skew alarms. Also, the virtual instance clock is synchronized with the host clock, so it is not absolutely required to configure NTP here.
```
system ntp-modify ntpservers=0.pool.ntp.org,1.pool.ntp.org
```

OpenStack-specific host configuration

Important

This step is required only if the StarlingX OpenStack application (stx-openstack) will be installed.

For OpenStack only: Assign OpenStack host labels to controller-0 in support of installing the stx-openstack manifest/helm-charts later:
```
system host-label-assign controller-0 openstack-control-plane=enabled
```
For OpenStack only: A vSwitch is required.

The default vSwitch is containerized OVS that is packaged with the stx-openstack manifest/helm-charts. StarlingX provides the option to use OVS-DPDK on the host, however, in the virtual environment OVS-DPDK is NOT supported, only OVS is supported. Therefore, simply use the default OVS vSwitch here.

Rook-specific host configuration

Important

This step is required only if the StarlingX Rook application will be installed.

For Rook only: Assign Rook host labels to controller-0 in support of installing the rook-ceph-apps manifest/helm-charts later and add ceph-rook as storage backend:

system host-label-assign controller-0 ceph-mon-placement=enabled
system host-label-assign controller-0 ceph-mgr-placement=enabled
system storage-backend-add ceph-rook --confirmed

Unlock controller-0

Unlock virtual controller-0 in order to bring it into service:

system host-unlock controller-0

Controller-0 will reboot in order to apply configuration changes and come into service. This can take 5-10 minutes, depending on the performance of the host machine.

Install software on controller-1 and worker nodes

On the host, power on the controller-1 virtual server, 'rookstorage-controller-1'. It will automatically attempt to network boot over the management network:
```
virsh start rookstorage-controller-1
```
Attach to the console of virtual controller-1:
```
virsh console rookstorage-controller-1
```
As controller-1 VM boots, a message appears on its console instructing you to configure the personality of the node.

On the console of controller-0, list hosts to see newly discovered controller-1 host (hostname=None):

system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
| 2  | None         | None        | locked         | disabled    | offline      |
+----+--------------+-------------+----------------+-------------+--------------+

Using the host id, set the personality of this host to 'controller':
```
system host-update 2 personality=controller
```
This initiates software installation on controller-1. This can take 5-10 minutes, depending on the performance of the host machine.
While waiting on the previous step to complete, start up and set the personality for 'rookstorage-worker-0' and 'rookstorage-worker-1'. Set the personality to 'worker' and assign a unique hostname for each.

For example, start 'rookstorage-worker-0' from the host:
```
virsh start rookstorage-worker-0
```
Wait for new host (hostname=None) to be discovered by checking ‘system host-list’ on virtual controller-0:
```
system host-update 3 personality=worker hostname=rook-storage-0
```
Repeat for 'rookstorage-worker-1'. On the host:
```
virsh start rookstorage-worker-1
```
And wait for new host (hostname=None) to be discovered by checking ‘system host-list’ on virtual controller-0:
```
system host-update 4 personality=worker hostname=rook-storage-1
```
This initiates software installation on storage-0 and storage-1. This can take 5-10 minutes, depending on the performance of the host machine.
While waiting on the previous step to complete, start up and set the personality for 'rookstorage-worker-2' and 'rookstorage-worker-3'. Set the personality to 'worker' and assign a unique hostname for each.

For example, start 'rookstorage-worker-2' from the host:
```
virsh start rookstorage-worker-2
```
Wait for new host (hostname=None) to be discovered by checking ‘system host-list’ on virtual controller-0:
```
system host-update 5 personality=worker hostname=worker-0
```
Repeat for 'rookstorage-worker-3'. On the host:
```
virsh start controllerstorage-worker-3
```
And wait for new host (hostname=None) to be discovered by checking ‘system host-list’ on virtual controller-0:
```
system host-update 6 personality=worker hostname=worker-1
```
This initiates software installation on worker-0 and worker-1.

Wait for the software installation on controller-1, storage-0, storage-1, worker-0, and worker-1 to complete, for all virtual servers to reboot, and for all to show as locked/disabled/online in 'system host-list'.

system host-list
+----+----------------+-------------+----------------+-------------+--------------+
| id | hostname       | personality | administrative | operational | availability |
+----+----------------+-------------+----------------+-------------+--------------+
| 1  | controller-0   | controller  | unlocked       | enabled     | available    |
| 2  | controller-1   | controller  | unlocked       | enabled     | available    |
| 3  | rook-storage-0 | worker      | locked         | disabled    | offline      |
| 4  | rook-storage-1 | worker      | locked         | disabled    | offline      |
| 5  | worker-0       | worker      | locked         | disabled    | offline      |
| 6  | worker-1       | worker      | locked         | disabled    | offline      |
+----+----------------+-------------+----------------+-------------+--------------+

Configure controller-1

Rook-specific host configuration

Important

This step is required only if the StarlingX Rook application will be installed.

For Rook only: Assign Rook host labels to controller-1 in support of installing the rook-ceph-apps manifest/helm-charts later:

system host-label-assign controller-1 ceph-mon-placement=enabled
system host-label-assign controller-1 ceph-mgr-placement=enabled

Unlock controller-1

Configure storage nodes

On virtual controller-0:

Assign the cluster-host network to the MGMT interface for the storage nodes.

Note that the MGMT interfaces are partially set up by the network install procedure.
```
for NODE in rook-storage-0 rook-storage-1; do
   system interface-network-assign $NODE mgmt0 cluster-host
done
```
For Rook only: Assign Rook host labels to storage-0 in support of installing the rook-ceph-apps manifest/helm-charts later:
```
system host-label-assign rook-storage-0 ceph-mon-placement=enabled
```

Unlock storage nodes

Unlock virtual storage nodes in order to bring them into service:

for STORAGE in rook-storage-0 rook-storage-1; do
   system host-unlock $STORAGE
done

The storage nodes will reboot in order to apply configuration changes and come into service. This can take 5-10 minutes, depending on the performance of the host machine.

Configure worker nodes

On virtual controller-0:

Assign the cluster-host network to the MGMT interface for the worker nodes.

Note that the MGMT interfaces are partially set up automatically by the network install procedure.
```
for NODE in worker-0 worker-1; do
   system interface-network-assign $NODE mgmt0 cluster-host
done
```

Configure data interfaces for worker nodes.

Important

This step is required only if the StarlingX OpenStack application (stx-openstack) will be installed.

1G Huge Pages are not supported in the virtual environment and there is no virtual NIC supporting SRIOV. For that reason, data interfaces are not applicable in the virtual environment for the Kubernetes-only scenario.

For OpenStack only:

DATA0IF=eth1000
DATA1IF=eth1001
PHYSNET0='physnet0'
PHYSNET1='physnet1'
SPL=/tmp/tmp-system-port-list
SPIL=/tmp/tmp-system-host-if-list

Configure the datanetworks in sysinv, prior to referencing it in the system host-if-modify command.

system datanetwork-add ${PHYSNET0} vlan
system datanetwork-add ${PHYSNET1} vlan

for NODE in worker-0 worker-1; do
  echo "Configuring interface for: $NODE"
  set -ex
  system host-port-list ${NODE} --nowrap > ${SPL}
  system host-if-list -a ${NODE} --nowrap > ${SPIL}
  DATA0PCIADDR=$(cat $SPL | grep $DATA0IF |awk '{print $8}')
  DATA1PCIADDR=$(cat $SPL | grep $DATA1IF |awk '{print $8}')
  DATA0PORTUUID=$(cat $SPL | grep ${DATA0PCIADDR} | awk '{print $2}')
  DATA1PORTUUID=$(cat $SPL | grep ${DATA1PCIADDR} | awk '{print $2}')
  DATA0PORTNAME=$(cat $SPL | grep ${DATA0PCIADDR} | awk '{print $4}')
  DATA1PORTNAME=$(cat $SPL | grep ${DATA1PCIADDR} | awk '{print $4}')
  DATA0IFUUID=$(cat $SPIL | awk -v DATA0PORTNAME=$DATA0PORTNAME '($12 ~ DATA0PORTNAME) {print $2}')
  DATA1IFUUID=$(cat $SPIL | awk -v DATA1PORTNAME=$DATA1PORTNAME '($12 ~ DATA1PORTNAME) {print $2}')
  system host-if-modify -m 1500 -n data0 -c data ${NODE} ${DATA0IFUUID}
  system host-if-modify -m 1500 -n data1 -c data ${NODE} ${DATA1IFUUID}
  system interface-datanetwork-assign ${NODE} ${DATA0IFUUID} ${PHYSNET0}
  system interface-datanetwork-assign ${NODE} ${DATA1IFUUID} ${PHYSNET1}
  set +ex
done

OpenStack-specific host configuration

Important

This step is required only if the StarlingX OpenStack application (stx-openstack) will be installed.

For OpenStack only: Assign OpenStack host labels to the worker nodes in support of installing the stx-openstack manifest/helm-charts later:

for NODE in worker-0 worker-1; do
  system host-label-assign $NODE  openstack-compute-node=enabled
  system host-label-assign $NODE  openvswitch=enabled
  system host-label-assign $NODE  sriov=enabled
done

For OpenStack only: Set up disk partition for nova-local volume group, which is needed for stx-openstack nova ephemeral disks:

for NODE in worker-0 worker-1; do
  echo "Configuring Nova local for: $NODE"
  ROOT_DISK=$(system host-show ${NODE} | grep rootfs | awk '{print $4}')
  ROOT_DISK_UUID=$(system host-disk-list ${NODE} --nowrap | grep ${ROOT_DISK} | awk '{print $2}')
  PARTITION_SIZE=10
  NOVA_PARTITION=$(system host-disk-partition-add -t lvm_phys_vol ${NODE} ${ROOT_DISK_UUID} ${PARTITION_SIZE})
  NOVA_PARTITION_UUID=$(echo ${NOVA_PARTITION} | grep -ow "| uuid | [a-z0-9\-]* |" | awk '{print $4}')
  system host-lvg-add ${NODE} nova-local
  system host-pv-add ${NODE} nova-local ${NOVA_PARTITION_UUID}
done

Unlock worker nodes

Unlock virtual worker nodes to bring them into service:

for NODE in worker-0 worker-1; do
   system host-unlock $NODE
done

The worker nodes will reboot in order to apply configuration changes and come into service. This can take 5-10 minutes, depending on the performance of the host machine.

Install Rook application manifest and helm-charts

On virtual storage-0 and storage-1:

Erase gpt header of disk sdb.

$ system host-disk-wipe -s --confirm rook-storage-0 /dev/sdb
$ system host-disk-wipe -s --confirm rook-storage-1 /dev/sdb

Wait for application "rook-ceph-apps" uploaded

$ source /etc/platform/openrc
$ system application-list
+---------------------+---------+-------------------------------+---------------+----------+-----------+
| application         | version | manifest name                 | manifest file | status   | progress  |
