Install Kubernetes Platform on Standard with Dedicated Storage

This section describes the steps to install the Kubernetes platform on a Standard with Dedicated Storage deployment configuration.

starlingx

Create bootable USB

Refer to Bootable USB <bootable_usb> for instructions on how to create a bootable USB with the StarlingX ISO on your system.

Install software on controller-0

Bootstrap system on controller-0

Configure controller-0

Unlock controller-0

Important

Make sure the Ceph storage backend is configured. If it is not configured, you will not be able to configure storage nodes.

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, storage nodes, and worker nodes

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

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

  3. 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      |
    +----+--------------+-------------+----------------+-------------+--------------+
  4. 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.

  5. While waiting for the previous step to complete, power on the storage-0 and storage-1 servers. Set the personality to 'storage' and assign a unique hostname for each.

    For example, power on storage-0 and wait for the new host (hostname=None) to be discovered by checking 'system host-list':

    system host-update 3 personality=storage

    Repeat for storage-1. Power on storage-1 and wait for the new host (hostname=None) to be discovered by checking 'system host-list':

    system host-update 4 personality=storage

    This initiates the software installation on storage-0 and storage-1. This can take 5-10 minutes, depending on the performance of the host machine.

  6. 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 5 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 6 personality=worker hostname=worker-1

    This initiates the install of software on worker-0 and worker-1.

    starlingx

    Note

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

  7. Wait for the software installation on controller-1, storage-0, storage-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  | storage-0    | storage     | locked         | disabled    | online       |
    | 4  | storage-1    | storage     | locked         | disabled    | online       |
    | 5  | worker-0     | worker      | locked         | disabled    | online       |
    | 6  | worker-1     | worker      | locked         | disabled    | online       |
    +----+--------------+-------------+----------------+-------------+--------------+

Configure controller-1

Unlock controller-1

Configure storage nodes

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

    (Note that the MGMT interfaces are partially set up automatically by the network install procedure.)

    for NODE in storage-0 storage-1; do
       system interface-network-assign $NODE mgmt0 cluster-host
    done
  2. Add to storage-0.

    HOST=storage-0
    
    # List hosts disks and identify disks you want to use for CEPH OSDs, taking note of their UUID
    # By default, /dev/sda is being used as system disk and can not be used for OSD.
    system host-disk-list ${HOST}
    
    # Add disk as an OSD storage
    system host-stor-add ${HOST} osd <disk-uuid>
    
    # List OSD storage devices and wait for configuration of newly added OSD to complete.
    system host-stor-list ${HOST}
  3. Add to storage-1.

    HOST=storage-1
    
    # List hosts disks and identify disks you want to use for CEPH OSDs, taking note of their UUID
    # By default, /dev/sda is being used as system disk and can not be used for OSD.
    system host-disk-list ${HOST}
    
    # Add disk as an OSD storage
    system host-stor-add ${HOST} osd <disk-uuid>
    
    # List OSD storage devices and wait for configuration of newly added OSD to complete.
    system host-stor-list ${HOST}

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.

Configure worker nodes

  1. The MGMT interfaces are partially set up by the network install procedure; configuring the port used for network install as the MGMT port and specifying the attached network of "mgmt".

    Complete the MGMT interface configuration of the worker nodes by specifying the attached network of "cluster-host".

    for NODE in worker-0 worker-1; do
       system interface-network-assign $NODE mgmt0 cluster-host
    done

openstack

OpenStack-specific host configuration

Important

These steps are required only if the application (-openstack) will be installed.

  1. For OpenStack only: Assign OpenStack host labels to the worker nodes in support of installing the stx-openstack manifest and 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
  2. For OpenStack only: Configure the host settings for the vSwitch.

    If using vswitch, run the following commands:

    Default recommendation for worker node is to use a single core on each numa-node for vswitch. This should have been automatically configured, if not run the following command.

    for NODE in worker-0 worker-1; do
    
       # assign 1 core on processor/numa-node 0 on worker-node to vswitch
       system host-cpu-modify -f vswitch -p0 1 $NODE
    
       # assign 1 core on processor/numa-node 1 on worker-node to vswitch
       system host-cpu-modify -f vswitch -p1 1 $NODE
    
    done

    When using , configure 1G of huge pages for vSwitch memory on each node where vswitch is running on the host. It is recommended to configure 1x 1G huge page (-1G 1) for vSwitch memory on each node where vswitch is running on host.

    However, due to a limitation with Kubernetes, only a single huge page size is supported on any one host. If your application require 2M huge pages, then configure 500x 2M huge pages (-2M 500) for vSwitch memory on each node where vswitch is running on host.

    for NODE in worker-0 worker-1; do
    
      # assign 1x 1G huge page on processor/numa-node 0 on worker-node to vswitch
      system host-memory-modify -f vswitch -1G 1 $NODE 0
    
      # assign 1x 1G huge page on processor/numa-node 0 on worker-node to vswitch
      system host-memory-modify -f vswitch -1G 1 $NODE 1
    
    done

    Important

    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 on this host, assuming 1G huge page size is being used on this host, with the following commands:

    for NODE in worker-0 worker-1; do
    
      # assign 10x 1G huge page on processor/numa-node 0 on worker-node to applications
      system host-memory-modify -f application -1G 10 $NODE 0
    
      # assign 10x 1G huge page on processor/numa-node 1 on worker-node to applications
      system host-memory-modify -f application -1G 10 $NODE 1
    
    done
  3. For OpenStack only: Setup disk partition for nova-local volume group, needed for stx-openstack nova ephemeral disks.

    for NODE in worker-0 worker-1; do
       system host-lvg-add ${NODE} nova-local
    
       # Get UUID of DISK to create PARTITION to be added to nova-local local volume group
       # CEPH OSD Disks can NOT be used
       # For best performance, do NOT use system/root disk, use a separate physical disk.
    
       # List hosts disks and take note of UUID of disk to be used
       system host-disk-list ${NODE}
       # ( if using ROOT DISK, select disk with device_path of
       #   system host-show ${NODE} --nowrap | fgrep rootfs   )
    
       # Create new PARTITION on selected disk, and take note of new partitions uuid in response
       # The size of the PARTITION needs to be large enough to hold the aggregate size of
       # all nova ephemeral disks of all VMs that you want to be able to host on this host,
       # but is limited by the size and space available on the physical disk you chose above.
       # The following example uses a small PARTITION size such that you can fit it on the
       # root disk, if that is what you chose above.
       # Additional PARTITION(s) from additional disks can be added later if required.
       PARTITION_SIZE=30
    
       system hostdisk-partition-add -t lvm_phys_vol ${NODE} <disk-uuid> ${PARTITION_SIZE}
    
       # Add new partition to nova-local local volume group
       system host-pv-add ${NODE} nova-local <NEW_PARTITION_UUID>
       sleep 2
    done
  4. For OpenStack only: Configure data interfaces for worker nodes. Data class interfaces are vswitch interfaces used by vswitch to provide virtio vNIC connectivity to OpenStack Neutron Tenant Networks on the underlying assigned Data Network.

    Important

    A compute-labeled worker host MUST have at least one Data class interface.

    • Configure the data interfaces for worker nodes.

      # Execute the following lines with
      export NODE=worker-0
      # and then repeat with
      export NODE=worker-1
      
         # List inventoried hosts ports and identify ports to be used as data interfaces,
         # based on displayed linux port name, pci address and device type.
         system host-port-list ${NODE}
      
         # List hosts auto-configured ethernet interfaces,
         # find the interfaces corresponding to the ports identified in previous step, and
         # take note of their UUID
         system host-if-list -a ${NODE}
      
         # Modify configuration for these interfaces
         # Configuring them as data class interfaces, MTU of 1500 and named data#
         system host-if-modify -m 1500 -n data0 -c data ${NODE} <data0-if-uuid>
         system host-if-modify -m 1500 -n data1 -c data ${NODE} <data1-if-uuid>
      
         # Create Data Networks that vswitch 'data' interfaces will be connected to
         DATANET0='datanet0'
         DATANET1='datanet1'
         system datanetwork-add ${DATANET0} vlan
         system datanetwork-add ${DATANET1} vlan
      
         # Assign Data Networks to Data Interfaces
         system interface-datanetwork-assign ${NODE} <data0-if-uuid> ${DATANET0}
         system interface-datanetwork-assign ${NODE} <data1-if-uuid> ${DATANET1}

Optionally Configure PCI-SRIOV Interfaces

  1. Optionally, configure pci-sriov interfaces for worker nodes.

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

    openstack

    This step is optional for OpenStack. Do this step if using vNICs in hosted application . Note that pci-sriov interfaces can have the same Data Networks assigned to them as vswitch data interfaces.

    • Configure the pci-sriov interfaces for worker nodes.

      # Execute the following lines with
      export NODE=worker-0
      # and then repeat with
      export NODE=worker-1
      
         # List inventoried hosts ports and identify ports to be used as pci-sriov interfaces,
         # based on displayed linux port name, pci address and device type.
         system host-port-list ${NODE}
      
         # List hosts auto-configured ethernet interfaces,
         # find the interfaces corresponding to the ports identified in previous step, and
         # take note of their UUID
         system host-if-list -a ${NODE}
      
         # Modify configuration for these interfaces
         # Configuring them as pci-sriov class interfaces, MTU of 1500 and named sriov#
         system host-if-modify -m 1500 -n sriov0 -c pci-sriov ${NODE} <sriov0-if-uuid>
         system host-if-modify -m 1500 -n sriov1 -c pci-sriov ${NODE} <sriov1-if-uuid>
      
         # If not created already, create Data Networks that the 'pci-sriov'
         # interfaces will be connected to
         DATANET0='datanet0'
         DATANET1='datanet1'
         system datanetwork-add ${DATANET0} vlan
         system datanetwork-add ${DATANET1} vlan
      
         # Assign Data Networks to PCI-SRIOV Interfaces
         system interface-datanetwork-assign ${NODE} <sriov0-if-uuid> ${DATANET0}
         system interface-datanetwork-assign ${NODE} <sriov1-if-uuid> ${DATANET1}
    • For Kubernetes only: To enable using network attachments for the above interfaces in Kubernetes hosted application containers:

      • Configure the Kubernetes device plugin.

        for NODE in worker-0 worker-1; do
           system host-label-assign $NODE sriovdp=enabled
        done
      • If planning on running in Kubernetes hosted application containers on this host, configure the number of 1G Huge pages required on both nodes.

        for NODE in worker-0 worker-1; do
        
           # assign 10x 1G huge page on processor/numa-node 0 on worker-node to applications
           system host-memory-modify -f application $NODE 0 -1G 10
        
           # assign 10x 1G huge page on processor/numa-node 1 on worker-node to applications
           system host-memory-modify -f application $NODE 1 -1G 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.
