Preparing Servers

ToDo - same as bare metal 2x Controllers, 2x Storage and 2x Computes

StarlingX Kubernetes

Installing StarlingX Kubernetes

Create a bootable USB with the StarlingX ISO

Get the StarlingX ISO. This can be from a private StarlingX build or, as shown below, from the public Cengen StarlingX build off 'master' branch:

wget http://mirror.starlingx.cengn.ca/mirror/starlingx/master/centos/latest_build/outputs/iso/bootimage.iso

Create a bootable USB with the StarlingX ISO:

# Insert USB stick

# Identify USB in mounted filesystems
$ df

# Unmount
$ sudo umount /media/vivek/data

# Use 'dd' to copy StarlingX bootimage.iso to USB
$ sudo dd if=artful-desktop-amd64.iso of=/dev/sdd bs=1M status=progress


Install Software on Controller-0

Insert the bootable USB into a bootable USB port on the host you are configuring as controller-0.

Power on the host.

Attach to a console, ensure the host boots from the USB and wait for the StarlingX Installer Menus.

Installer Menu Selections:

  • First Menu
    • Select 'Standard Controller Configuration'
  • Second Menu
    • Select 'Graphical Console' or 'Textual Console' depending on your terminal access to the console port
  • Third Menu
    • Select 'Standard Security Profile'


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

Bootstrap System on Controller-0

Login with username / password of sysadmin / sysadmin.
When logging in for the first time, you will be forced to change the password.

Login: sysadmin
Password:
Changing password for sysadmin.
(current) UNIX Password: sysadmin
New Password:
(repeat) New Password:


External connectivity is required to run the Ansible bootstrap playbook. The StarlingX boot image will DHCP out all interfaces so if a DHCP server is present in your environment, the server may have obtained an IP Address and have external IP connectivity by these means; check with 'ip add' and 'ping 8.8.8.8'.

Otherwise, manually configure an IP Address and Default IP Route.
Use the PORT, IP-ADDRESS/SUBNET-LENGTH and GATEWAY-IP-ADDRESS applicable to your deployment environment.

sudo ip address add <IP-ADDRESS>/<SUBNET-LENGTH> dev <PORT>
sudo ip link set up dev <PORT>
sudo ip route add default via <GATEWAY-IP-ADDRESS> dev <PORT>
ping 8.8.8.8


Ansible is used to bootstrap StarlingX on Controller-0:

  • The default Ansible inventory file, /etc/ansible/hosts, contains a single host, localhost.
  • The Ansible bootstrap playbook is at /usr/share/ansible/stx-ansible/playbooks/bootstrap/bootstrap.yml .
  • The default configuration values for the bootstrap playbook are in /usr/share/ansible/stx-ansible/playbooks/bootstrap/host_vars/default.yml .
  • By default Ansible looks for and imports user configuration override files for hosts in the sysadmin home directory ($HOME), e.g. $HOME/<hostname>.yml .


Specify the user configuration override file for the ansible bootstrap playbook, by copying the above default.yml file to $HOME/localhost.yml and edit the configurable values as desired, based on the commented instructions in the file.
or
Simply create the minimal user configuration override file as shown below, using the OAM IP SUBNET and IP ADDRESSing applicable to your deployment environment.

cd ~
cat <<EOF > localhost.yml 
system_mode: standard

dns_servers:
  - 8.8.8.8
  - 8.8.4.4

external_oam_subnet: <OAM-IP-SUBNET>/<OAM-IP-SUBNET-LENGTH>
external_oam_gateway_address: <OAM-GATEWAY-IP-ADDRESS>
external_oam_floating_address: <OAM-FLOATING-IP-ADDRESS>
external_oam_node_0_address: <OAM-CONTROLLER-0-IP-ADDRESS>
external_oam_node_1_address: <OAM-CONTROLLER-1-IP-ADDRESS>

admin_username: admin
admin_password: <sysadmin-password>
ansible_become_pass: <sysadmin-password>
EOF

Run the Ansible bootstrap playbook:

ansible-playbook /usr/share/ansible/stx-ansible/playbooks/bootstrap/bootstrap.yml

Wait for Ansible bootstrap playbook to complete.
This can take 5-10 mins depending on performance of HOST machine.


Configure Controller-0

Acquire admin credentials:

source /etc/platform/openrc

Configure the OAM and MGMT interfaces of controller-0 and specify the attached networks:
(Use the OAM and MGMT port names, e.g. eth0, applicable to your deployment environment.)

OAM_IF=<OAM-PORT>
MGMT_IF=<MGMT-PORT>
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:

system ntp-modify ntpservers=0.pool.ntp.org,1.pool.ntp.org


Configure data interfaces for controller-0:
(Use the DATA port names, e.g. eth0, applicable to your deployment environment.)

DATA0IF=<DATA-0-PORT>
DATA1IF=<DATA-1-PORT>
export COMPUTE=controller-0
PHYSNET0='physnet0'
PHYSNET1='physnet1'
SPL=/tmp/tmp-system-port-list
SPIL=/tmp/tmp-system-host-if-list
system host-port-list ${COMPUTE} --nowrap > ${SPL}
system host-if-list -a ${COMPUTE} --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 datanetwork-add ${PHYSNET0} vlan

system interface-datanetwork-assign ${COMPUTE} ${DATA0IFUUID} ${PHYSNET0}
system interface-datanetwork-assign ${COMPUTE} ${DATA1IFUUID} ${PHYSNET1}


Add an OSD on controller-0 for ceph:

echo ">>> Add OSDs to primary tier"
system host-disk-list controller-0
system host-disk-list controller-0 | awk '/\/dev\/sdb/{print $2}' | xargs -i system host-stor-add controller-0 {}
system host-stor-list controller-0


OpenStack-specific Host Configuration

Caution icon.svg OpenStack-ONLY

The following configuration is only required if the 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
system host-label-assign controller-0 openstack-compute-node=enabled
system host-label-assign controller-0 openvswitch=enabled
system host-label-assign controller-0 sriov=enabled


For OpenStack ONLY, configure the system setting for the vSwitch.

StarlingX has OVS (kernel-based) vSwitch configured as default:

  • Running in a container; defined within the helm charts of stx-openstack manifest.
  • Shares the core(s) assigned to the Platform.


If you require better performance, OVS-DPDK should be used:

  • Running directly on the host (i.e. NOT containerized).
  • Requires that at least 1 core be assigned/dedicated to the vSwitch function.


To deploy the default containerized OVS:

system modify --vswitch_type none

I.e. do not run any vSwitch directly on the host, and use the containerized OVS defined in the helm charts of stx-openstack manifest.

To deploy OVS-DPDK (OVS with the Data Plane Development Kit, which is supported only on bare metal hardware, run the following command:

system modify --vswitch_type ovs-dpdk
system host-cpu-modify -f vswitch -p0 1 controller-0

Once vswitch_type is set to OVS-DPDK, any subsequent nodes created will default to automatically assigning 1 vSwitch core for AIO Controllers and 2 vSwitch cores for Computes.


When using OVS-DPDK, Virtual Machines must be configured to use a flavor with property: hw:mem_page_size=large.

Caution icon.svg Important

After controller-0 is unlocked, changing vswitch_type would require locking and unlocking all computes (and/or AIO Controllers) in order to apply the change.


For OpenStack Only, setup disk partition for nova-local volume group, needed for stx-openstack nova ephemeral disks.

export COMPUTE=controller-0

echo ">>> Getting root disk info"
ROOT_DISK=$(system host-show ${COMPUTE} | grep rootfs | awk '{print $4}')
ROOT_DISK_UUID=$(system host-disk-list ${COMPUTE} --nowrap | grep ${ROOT_DISK} | awk '{print $2}')
echo "Root disk: $ROOT_DISK, UUID: $ROOT_DISK_UUID"

echo ">>>> Configuring nova-local"
NOVA_SIZE=34
NOVA_PARTITION=$(system host-disk-partition-add -t lvm_phys_vol ${COMPUTE} ${ROOT_DISK_UUID} ${NOVA_SIZE})
NOVA_PARTITION_UUID=$(echo ${NOVA_PARTITION} | grep -ow "| uuid | [a-z0-9\-]* |" | awk '{print $4}')
system host-lvg-add ${COMPUTE} nova-local
system host-pv-add ${COMPUTE} nova-local ${NOVA_PARTITION_UUID}
sleep 2

echo ">>> Wait for partition $NOVA_PARTITION_UUID to be ready."
while true; do system host-disk-partition-list $COMPUTE --nowrap | grep $NOVA_PARTITION_UUID | grep Ready; if [ $? -eq 0 ]; then break; fi; sleep 1; done



Unlock Controller-0

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

system host-unlock controller-0

Controller-0 will reboot in order to apply configuration change and come into service.
This can take 5-10 mins depending on performance of HOST machine.


Install Software on Controller-1 Node

Power on the controller-1 server and force it to network boot with the appropriate BIOS Boot Options for your particular server.

As controller-1 boots, a message appears on its console instructing you to configure the personality of the node.


On console of controller-0,
list hosts to see newly discovered controller-1 host, i.e. host with hostname of 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

Wait for the install of software on controller-1 to complete, controller-1 to reboot and controller-1 to show as locked/disabled/online in 'system host-list'.
This can take 5-10 mins depending on performance of HOST machine.

system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
| 2  | controller-1 | controller  | locked         | disabled    | online      |
+----+--------------+-------------+----------------+-------------+--------------+



Configure Controller-1

Configure the OAM and MGMT interfaces of controller-1 and specify the attached networks:
