Install Kubernetes Platform on Bare Metal Standard with Rook Storage

This section describes the steps to install the StarlingX Kubernetes platform on a StarlingX R7.0 bare metal Standard with Rook Storage deployment configuration.

Create bootable USB

Refer to /deploy_install_guides/bootable_usb for instructions on how to create a bootable USB with the StarlingX ISO on your system.

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.
Make the following menu selections in the installer:
1. First menu: Select 'Standard Controller Configuration'
2. Second menu: Select 'Graphical Console' or 'Textual Console' depending on your terminal access to the console port
Wait for non-interactive install of software to complete and server to reboot. This can take 5-10 minutes, depending on the performance of the server.

Bootstrap system on controller-0

Login using the 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:
```
Verify and/or configure IP connectivity.

External connectivity is required to run the Ansible bootstrap playbook. The StarlingX boot image will DHCP out all interfaces so the server may have obtained an IP address and have external IP connectivity if a DHCP server is present in your environment. Verify this using the ip addr and ping 8.8.8.8 commands.

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
```
Specify user configuration overrides for the Ansible bootstrap playbook.

Ansible is used to bootstrap StarlingX on controller-0. Key files for Ansible configuration are:

/etc/ansible/hosts

The default Ansible inventory file. Contains a single host: localhost.

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

The Ansible bootstrap playbook.

/usr/share/ansible/stx-ansible/playbooks/host_vars/bootstrap/default.yml

The default configuration values for the bootstrap playbook.

sysadmin home directory ($HOME)

The default location where Ansible looks for and imports user configuration override files for hosts. For example: $HOME/<hostname>.yml.

Specify the user configuration override file for the Ansible bootstrap playbook using one of the following methods:
1. Use a copy of the default.yml file listed above to provide your overrides.
  
  The default.yml file lists all available parameters for bootstrap configuration with a brief description for each parameter in the file comments.
  
  To use this method, copy the default.yml file listed above to $HOME/localhost.yml and edit the configurable values as desired.
2. Create a minimal user configuration override file.
  
  To use this method, create your override file at $HOME/localhost.yml and provide the minimum required parameters for the deployment configuration as shown in the example below. Use the OAM IP SUBNET and IP ADDRESSing applicable to your deployment environment.
```
cd ~
cat <<EOF > localhost.yml
system_mode: duplex

dns_servers:
  - 8.8.8.8
  - 8.8.4.4

Refer to Ansible Bootstrap Configurations <ansible_bootstrap_configs_r7> for information on additional Ansible bootstrap configurations for advanced Ansible bootstrap scenarios, such as Docker proxies when deploying behind a firewall, etc. Refer to Docker Proxy Configuration <docker_proxy_config> for details about Docker proxy settings.
Run the Ansible bootstrap playbook:
```
ansible-playbook /usr/share/ansible/stx-ansible/playbooks/bootstrap.yml
```
Wait for Ansible bootstrap playbook to complete. This can take 5-10 minutes, depending on the performance of the 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, for example eth0, that are 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

If required, and not already done as part of bootstrap, configure Docker to use a proxy server.
1. List Docker proxy parameters:
```
system service-parameter-list platform docker
```
2. Refer to docker_proxy_config for details about Docker proxy settings.

OpenStack-specific host configuration

Important

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

For OpenStack only: Assign OpenStack host labels to controller-0 in support of installing the -openstack manifest and helm-charts later.
```
system host-label-assign controller-0 openstack-control-plane=enabled
```
For OpenStack only: Configure the system setting for the vSwitch.

StarlingX has (kernel-based) vSwitch configured as default:
- Runs in a container; defined within the helm charts of -openstack manifest.
- Shares the core(s) assigned to the platform.
If you require better performance, - ( with the Data Plane Development Kit, which is supported only on bare metal hardware) should be used:
- Runs directly on the host (it is not containerized).
- Requires that at least 1 core be assigned/dedicated to the vSwitch function.
To deploy the default containerized :
```
system modify --vswitch_type none
```
Do not run any vSwitch directly on the host, instead, use the containerized defined in the helm charts of -openstack manifest.

To deploy -, 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 -, any subsequent nodes created will default to automatically assigning 1 vSwitch core for controllers and 2 vSwitch cores for compute-labeled worker nodes.

When using -, configure vSwitch memory per node with the following command:
```
system host-memory-modify -f <function> -1G <1G hugepages number> <hostname or id> <processor>
```
For example:
```
system host-memory-modify -f vswitch -1G 1 worker-0 0
```
created in an - environment must be configured to use huge pages to enable networking and must use a flavor with property: hw:mem_page_size=large

Configure the huge pages for in an - environment with the command:
```
system host-memory-modify -1G <1G hugepages number> <hostname or id> <processor>
```
For example:
```
system host-memory-modify worker-0 0 -1G 10
```
Note

After controller-0 is unlocked, changing vswitch_type requires locking and unlocking all compute-labeled worker nodes (and/or controllers) to apply the change.

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 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

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 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 the install of software on controller-1. This can take 5-10 minutes, depending on the performance of the host machine.
While waiting for the previous step to complete, power on the worker nodes. Set the personality to 'worker' and assign a unique hostname for each.

For example, power on worker-0 and wait for the new host (hostname=None) to be discovered by checking 'system host-list':
```
system host-update 3 personality=worker hostname=worker-0
```
Repeat for worker-1. Power on worker-1 and wait for the new host (hostname=None) to be discovered by checking 'system host-list':
```
system host-update 4 personality=worker hostname=worker-1
```
For rook storage, there is no storage personality. Some hosts with worker personality providers storage service. Here we still named these worker host storage-x. Repeat for storage-0 and storage-1. Power on storage-0, storage-1 and wait for the new host (hostname=None) to be discovered by checking 'system host-list':
```
system host-update 5 personality=worker hostname=storage-0
system host-update 6 personality=worker hostname=storage-1
```
starlingx

Note

A node with Edgeworker personality is also available. See deploy-edgeworker-nodes for details.

Wait for the software installation on controller-1, worker-0, and worker-1 to complete, for all 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  | locked         | disabled    | online       |
| 3  | worker-0     | worker      | locked         | disabled    | online       |
| 4  | worker-1     | worker      | locked         | disabled    | online       |
| 5  | storage-0    | worker      | locked         | disabled    | online       |
| 6  | storage-1    | worker      | locked         | disabled    | online       |
+----+--------------+-------------+----------------+-------------+--------------+

Configure controller-1

Configure the and MGMT interfaces of controller-0 and specify the attached networks. Use the and MGMT port names, for example eth0, that are applicable to your deployment environment.

(Note that the MGMT interface is partially set up automatically by the network install procedure.)

OAM_IF=<OAM-PORT>
MGMT_IF=<MGMT-PORT>
system host-if-modify controller-1 $OAM_IF -c platform
system interface-network-assign controller-1 $OAM_IF oam
system interface-network-assign controller-1 $MGMT_IF cluster-host

OpenStack-specific host configuration

Important

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

For OpenStack only: Assign OpenStack host labels to controller-1 in support of installing the -openstack manifest and helm-charts later.

system host-label-assign controller-1 openstack-control-plane=enabled

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

Unlock controller-1 in order to bring it into service:

system host-unlock controller-1

Controller-1 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

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. Use the DATA port names, for example eth0, that are applicable to your deployment environment.

Important

This step is required for OpenStack.

This step is optional for Kubernetes: Do this step if using network attachments in hosted application containers.

For Kubernetes network attachments:

Configure device plug in:

for NODE in worker-0 worker-1; do
   system host-label-assign ${NODE} sriovdp=enabled
done

If planning on running in containers on this host, configure the number of 1G Huge pages required on both nodes:

for NODE in worker-0 worker-1; do
   system host-memory-modify ${NODE} 0 -1G 100
   system host-memory-modify ${NODE} 1 -1G 100
done

For both Kubernetes and OpenStack:

DATA0IF=<DATA-0-PORT>
DATA1IF=<DATA-1-PORT>
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}

  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 (-openstack) will be installed.

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

starlingx

for NODE in worker-0 worker-1; do

system host-label-assign $NODE openstack-compute-node=enabled kubectl taint nodes $NODE openstack-compute-node:NoSchedule system host-label-assign $NODE system host-label-assign $NODE sriov=enabled

done

partner

For OpenStack only: Set up 'instances' filesystem, which is needed for -openstack nova ephemeral disks.

for NODE in worker-0 worker-1; do
  echo "Configuring 'instances' for Nova ephemeral storage: $NODE"
  system host-fs-add ${NODE} instances=10
done

Unlock worker nodes

Unlock worker nodes in order 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.

Configure storage nodes

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 storage-0 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 storage-0 ceph-mon-placement=enabled
```

Unlock storage nodes

Unlock storage nodes in order to bring them into service:

for STORAGE in storage-0 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.

Install Rook application manifest and helm-charts

On host storage-0 and storage-1:

Erase gpt header of disk sdb.

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

Wait for application "rook-ceph-apps" uploaded
