README.md

Deploy OpenStack Xena MultiNode on Ubuntu 20.04LTS

Goals

• Can access on endpoint console.bignetlab.com
• Prometheus & Grafana Ready

Prerequisite

• 3 NODE
  • 1 CONTROLLER
  • 2 WORKER
  • 3 Interface (NAT/BRDIGE(NO IP)/Bridge with IP)
  • 2 Storage (vda&vdb) per Node
• Network
  • ens3 : 192.168.2.0/24
  • ens4 : 192.168.3.0/24 (without IP)
  • ens5 : 192.168.3.0/24 (with IP)

Configuration

• Add Hosts Record

nano /etc/hosts

192.168.2.50 console.gbesar.com
192.168.2.202 ctrl1
192.168.2.203 comp1
192.168.2.204 comp2

All Node

• Add User

  adduser kolla
  usermod -aG sudo kolla
  echo "kolla ALL=(ALL) NOPASSWD:ALL" | tee /etc/sudoers.d/kolla
  

• Create volume group for cinder service

  su - kolla
  sudo pvcreate /dev/vdb
  sudo vgcreate cinder-volumes /dev/vdb 
  sudo vgs
  

Controller Node :

• Install Dependencies

sudo apt-get install python3-dev libffi-dev gcc libssl-dev python3-selinux python3-setuptools python3-venv -y

• Create a virtual environment and activate it

python3 -m venv kolla-venv
source kolla-venv/bin/activate

• Ensure the latest version of pip is installed

pip install -U pip

• Install wheel

pip install wheel

• Install Ansible

pip install 'ansible<3.0'

• Config ansible.cfg - use user kolla (controller)

sudo mkdir -p /etc/ansible
sudo nano /etc/ansible/ansible.cfg

[defaults]
host_key_checking=False
pipelining=True
forks=100

• Install kolla-ansible and its dependencies using pip

pip install kolla-ansible

• Specify Jinja Stable

pip uninstall jinja2
pip install jinja2==3.0.3

• Create the /etc/kolla directory.

sudo mkdir -p /etc/kolla
sudo chown $USER:$USER /etc/kolla

• Copy globals.yml and passwords.yml to /etc/kolla directory

cp -r kolla-venv/share/kolla-ansible/etc_examples/kolla/* /etc/kolla

• Copy all-in-one and multinode inventory files to the current directory.

cp kolla-venv/share/kolla-ansible/ansible/inventory/* .

• Distribute SSH-Keygen to all node

ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub kolla@ctrl1
ssh-copy-id -i ~/.ssh/id_rsa.pub kolla@comp1
ssh-copy-id -i ~/.ssh/id_rsa.pub kolla@comp2

• Specify Role Node

nano ~/multinode 

[control] 
ctrl1

[network] 
ctrl1

[compute] 
comp1
comp2

[monitoring]
ctrl1

[storage]
ctrl1
comp1
comp2

[deployment] 
localhost ansible_connection=local 

Note: Dont change other configuration.

• Check Connection to all Node

ansible -i multinode all -m ping

• Generate Password

kolla-genpwd

• Declare base service what you want to deploy
  • kolla_internal_vip_address are IP from adapter who have access internet and some free pool subnet to access.
  • kolla_internal_fqdn are domain that you want to access to your openstack cluster.
  • neutron_external_interface are adapter that have an some free pool subnet, internet access & not have an IP.

nano /etc/kolla/globals.yml

kolla_base_distro: "ubuntu"
kolla_install_type: "source"
openstack_release: "xena"
kolla_internal_vip_address: "192.168.2.80"
kolla_internal_fqdn: "console.bignetlab.com"
kolla_enable_tls_internal: "yes"
kolla_copy_ca_into_containers: "yes"
kolla_enable_tls_backend: "yes"
openstack_cacert: "/etc/ssl/certs/ca-certificates.crt"
network_interface: "ens3"
neutron_external_interface: "ens4"
neutron_plugin_agent: "openvswitch"
enable_openstack_core: "yes"
enable_haproxy: "yes"
enable_neutron_provider_networks: "yes"
nova_compute_virt_type: "kvm"
enable_cinder: "yes"
enable_cinder_backend_lvm: "yes"
cinder_volume_group: "cinder-volumes"
enable_prometheus: "yes"
enable_prometheus_openstack_exporter: "yes"
enable_grafana: "yes"
enable_mariadb_clustercheck: "yes"

• Ready to Deploy

kolla-ansible -i ./multinode certificates
kolla-ansible -i ./multinode bootstrap-servers
kolla-ansible -i ./multinode prechecks
kolla-ansible -i ./multinode deploy
kolla-ansible post-deploy

Note

• If you not use TLS on your cluster, you can skip the TLS command and declare on globals.yml & certificates on deploy.
• If you use TLS, you can inject TLS key to your admin-openrc.sh with :

  cat /etc/kolla/certificates/ca/root.crt | sudo tee -a /etc/ssl/certs/ca-certificates.crt
  source /etc/kolla/admin-openrc.sh
  

• for Network, you can create and use type FLAT and physnet1 for Variable or you can check with $ grep bridge_mappings /etc/kolla/neutron-openvswitch-agent/openvswitch_agent.ini
• Access anything with VIP_ADDRESS:
  • Horizon on 192.168.2.80 or console.bignetlab.com
  • Grafana on 192.168.2.80:3000 or console.bignetlab.com:3000
  • Prometheus on 192.168.2.80:9090 or console.bignetlab.com:9090
• Make sure you must mark apt-update docker&containerd on linux to avoid crash/auto restarting docker who effect with operational cluster with

  apt-mark showhold
  apt-mark hold docker containerd
