Deployment Diagram
Physical Host Requirements for Virtual Servers
The recommended minimum requirements for the workstation, hosting the virtual machine(s) where StarlingX will be deployed, include:
Hardware Requirements
A workstation computer with minimally:
- Processor: x86_64 only supported architecture with BIOS enabled hardware virtualization extensions
- Cores: 8
- Memory: 32GB RAM
- Hard Disk: 500GB HDD
- Network: One network adapter with active Internet connection
Software Requirements
A workstation computer with Ubuntu 16.04 LTS 64-bit .
All other required packages will be installed by scripts in StarlingX tools repo.
Host Setup
Update OS:
apt-get update
Clone the StarlingX tools repository:
apt-get install -y git cd $HOME git clone https://opendev.org/starlingx/tools
Install required packages:
cd $HOME/tools/deployment/libvirt/ bash install_packages.sh apt install -y apparmor-profiles apt-get install -y ufw ufw disable ufw status
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
Prepare the Virtual Environment and Virtual Servers
Setup virtual platform networks for virtual deployment:
bash setup_network.sh
Create the XML definitions for the virtual servers required by this configuration option.
This will create the XML virtual server definition for:
- simplex-controller-0
The following command will also start the X-based graphical virt-manager application; if their is no X-server present then errors will occur.
The following command will also start/virtually-powered-on the 'simplex-controller-0' virtual server.
bash setup_configuration.sh -c simplex -i ./bootimage.iso
StarlingX Kubernetes
Install the StarlingX Kubernetes Platform
Install Software on Controller-0
The controller-0 virtual server, 'simplex-controller-0', has been started/virtually-powered-on by the previous 'setup_configuration.sh' command.
Attach to the console of virtual controller-0 and select the appropriate installer menu options in order to start the non-interactive install of StarlingX software on controller-0.
When entering the console it is very easy to miss the first installer menu selection; use ESC to go to previous menus, in order to ensure you are at the first installer menu selection.
virsh console simplex-controller-0
Installer Menu Selections:
- First Menu
- Select 'All-in-one Controller Configuration'
- Second Menu
- Select 'Graphical Console'
- 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 HOST machine.
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.
export CONTROLLER0_OAM_CIDR=10.10.10.3/24 export DEFAULT_OAM_GATEWAY=10.10.10.1 sudo ip address add $CONTROLLER0_OAM_CIDR dev enp7s1 sudo ip link set up dev enp7s1 sudo ip route add default via $DEFAULT_OAM_GATEWAY dev enp7s1
Ansible is used to bootstrap StarlingX on Controller-0:
- The default Ansible inventory file, /etc/ansible/hosts, contains a single host, localhost.
- The Ansible bootstrap playbook is at /usr/share/ansible/stx-ansible/playbooks/bootstrap/bootstrap.yml .
- The default configuration values for the bootstrap playbook are in /usr/share/ansible/stx-ansible/playbooks/bootstrap/host_vars/default.yml .
- By default Ansible looks for and imports user configuration override files for hosts in the sysadmin home directory ($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:
cd ~ cat <<EOF > localhost.yml system_mode: simplex dns_servers: - 8.8.8.8 - 8.8.4.4 external_oam_subnet: 10.10.10.0/24 external_oam_gateway_address: 10.10.10.1 external_oam_floating_address: 10.10.10.2 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 interface of controller-0:
OAM_IF=enp7s1 system host-if-modify controller-0 $OAM_IF -c platform system interface-network-assign controller-0 $OAM_IF oam
Configure NTP Servers for network time synchronization:
In virtual environment this can sometimes cause Ceph’s clock skew alarms. Moreover, clock of virtual instances 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
OPTIONALLY for Kubernetes, i.e. if planning on using SRIOV network attachments in application containers, or
REQUIRED for OpenStack,
configure data interfaces for controller-0:
# For Kubernetes SRIOV network attachments # configure SRIOV device plugin system host-label-assign controller-0 sriovdp=enabled # If planning on running DPDK in containers on this hosts, configure number of 1G Huge pages required on both NUMA nodes system host-memory-modify controller-0 0 -1G 100 system host-memory-modify controller-0 0 -1G 100 # For both Kubernetes and OpenStack DATA0IF=eth1000 DATA1IF=eth1001 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 datanetwork-add ${PHYSNET1} vlan system host-if-modify -m 1500 -n data0 -c data ${COMPUTE} ${DATA0IFUUID} system host-if-modify -m 1500 -n data1 -c data ${COMPUTE} ${DATA1IFUUID} 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 $2}' | xargs -i system host-stor-add controller-0 {} system host-stor-list controller-0
OpenStack-specific Host Configuration
The following configuration is only required if the OpenStack application (stx-openstack) will be installed.
For OpenStack ONLY, assign OpenStack host labels to controller-0 in support of installing the stx-openstack manifest/helm-charts later.
system host-label-assign controller-0 openstack-control-plane=enabled system host-label-assign controller-0 openstack-compute-node=enabled system host-label-assign controller-0 openvswitch=enabled system host-label-assign controller-0 sriov=enabled
For OpenStack ONLY, a vSwitch is required.
- The default vSwitch is containerized OVS that is packaged with the stx-openstack manifest/helm-charts. StarlingX provides the option to use OVS-DPDK on the host, however in the virtual environment OVS-DPDK is NOT supported, only OVS is supported. Therefore simply use the default OVS vSwitch here.
For OpenStack Only, setup disk partition for nova-local volume group, needed for stx-openstack nova ephemeral disks.
export COMPUTE=controller-0 echo ">>> Getting root disk info" ROOT_DISK=$(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.
When it completes, your Kubernetes Cluster is up and running.
Access StarlingX Kubernetes
Use Local/Remote CLIs, GUIs and/or REST APIs to access and manage StarlingX Kubernetes and hosted containerized applications. See details on accessing the StarlingX Kubernetes Cluster here.
StarlingX OpenStack
Install StarlingX OpenStack
Other than the OpenStack-specific configurations required in the underlying StarlingX/Kubernetes infrastructure done in the above installation steps for the StarlingX Kubernetes Platform, the installation of containerized OpenStack is independent of deployment configuration and can be found here.
