Is it possible to add compute nodes into OpenStack using Kolla-Ansible? Yes, definitely. In this step-by-step guide, you will learn how to add compute nodes into an existing OpenStack deployment using Kolla-Ansible. Kolla-Ansible, a cutting-edge tool in the world of cloud orchestration, simplifies the process of integrating additional compute nodes into an existing OpenStack deployment seamlessly.

Adding Compute Nodes into OpenStack using Kolla-Ansible
In our previous guide, we learnt how to deploy multinode OpenStack with three node, Controller, Storage and compute nodes, using Kolla-Ansible.
When you speak about openstack compute, there are two terms that can be interchangeably used. These terms are compute node and compute host.
Compute Node
- A compute node, also known as a compute server or hypervisor host, is a physical or virtual server that runs virtual machines (VMs). It provides the computational resources, such as CPU, memory, and storage, for running VMs. Compute nodes are responsible for creating, terminating, and managing VMs, including tasks like scheduling and resource allocation.
- In OpenStack, a compute node runs the Nova Compute service and is part of the compute resource pool available for launching and managing VMs.
Compute Host
- A compute host is a term that can be used interchangeably with a compute node in some contexts. However, in other cases, a compute host might refer to the physical or virtual machine that acts as a host for multiple compute nodes.
- For example, in a scenario where multiple compute nodes run on a single physical server or hypervisor, that physical server could be referred to as the compute host.
Let’s confirm the number of compute nodes we currently have in our deployment
source $HOME/kolla-ansible/bin/activatesource /etc/kolla/admin-openrc.shopenstack hypervisor listSample output;
+--------------------------------------+---------------------+-----------------+-----------------+-------+
| ID | Hypervisor Hostname | Hypervisor Type | Host IP | State |
+--------------------------------------+---------------------+-----------------+-----------------+-------+
| 6aa76044-d456-4c3b-8f28-fcfc7e79b658 | compute01 | QEMU | 192.168.200.202 | up |
+--------------------------------------+---------------------+-----------------+-----------------+-------+
As you can see, we only have one single compute node at the moment.
Prepare the Nodes for Addition into OpenStack
Well, since we are using Kolla-Ansible for deployment, most of the pre-requisites will be taken care by Kolla-Ansible.
However, the fresh installation, initial IP assignent to the node, hostname, creation of first user accounts, you need to do this yourself (You can automate if you want).
Also, I would recommend that you use same OS version for uniformity across the cluster and easy management. We are running Ubuntu 22.04 LTS
Based on our basic deployment architecture;
------------------+---------------------------------------------+--------------------------------+

+-----------------+-------------------------+ +-------------+-------------+ +------------+--------------+

we have setup our node, assigned the IP addresses, create required user account with required sudo rights. Our basic architecture will now look like;

Copy Deployment User SSH Keys from Control Node to New Compute Node
Your control node is the node where you are running Kolla-ansible. In our setup, we are running Kolla-ansible in our controller node.
In regards to the deployment user, if you are not using SSH keys, you need to define the username and password in the multinode configuration file for the respective compute to define how Kolla-Ansible will login to configure that respective node.
We are using SSH keys on our guide which we already generated while creating Kolla-Ansible Deployment User Account.
Hence, let just copy the SSH keys into the new compute node.
First of all, let’s ensure the new compute node is reachable via the hostname from the control node.
sudo tee -a /etc/hosts << EOL
192.168.200.203 compute02
EOLLet’s confirm reachability;
ping compute02 -c 4PING compute02 (192.168.200.203) 56(84) bytes of data.

Next, copy the keys;
ssh-copy-id kifarunix@compute02Update Kolla-Ansible Inventory
Since we are running a multinode deployment, open the multinode inventory and add your new compute node.
This is a snippet of how our multinode inventory looks like before we add the new compute node;
cat multinode# These initial groups are the only groups required to be modified. The
# additional groups are for more control of the environment.
[control]
controller01 ansible_connection=local neutron_external_interface=vethext
# The above can also be specified as follows:
#control[01:03] ansible_user=kolla
# The network nodes are where your l3-agent and loadbalancers will run
# This can be the same as a host in the control group
[network]
controller01 ansible_connection=local neutron_external_interface=vethext network_interface=br0
[compute]
compute01 neutron_external_interface=enp2s0 network_interface=enp1s0
[monitoring]
controller01 ansible_connection=local neutron_external_interface=vethext
# When compute nodes and control nodes use different interfaces,
# you need to comment out "api_interface" and other interfaces from the globals.yml
# and specify like below:
#compute01 neutron_external_interface=eth0 api_interface=em1 tunnel_interface=em1
[storage]
storage01 neutron_external_interface=enp10s0 network_interface=enp1s0
[deployment]
localhost ansible_connection=local
[baremetal:children]
control
network
compute
storage
monitoring
[tls-backend:children]
control
# You can explicitly specify which hosts run each project by updating the
# groups in the sections below. Common services are grouped together.
[common:children]
control
network
compute
storage
monitoring
...
So, we will update the [compute] group to add our new node such that the configuration looks like;
vim multinode# These initial groups are the only groups required to be modified. The
# additional groups are for more control of the environment.
[control]
controller01 ansible_connection=local neutron_external_interface=vethext
# The above can also be specified as follows:
#control[01:03] ansible_user=kolla
# The network nodes are where your l3-agent and loadbalancers will run
# This can be the same as a host in the control group
[network]
controller01 ansible_connection=local neutron_external_interface=vethext network_interface=br0
[compute]
compute01 neutron_external_interface=enp2s0 network_interface=enp1s0
compute02 neutron_external_interface=enp2s0 network_interface=enp1s0
[monitoring]
controller01 ansible_connection=local neutron_external_interface=vethext
# When compute nodes and control nodes use different interfaces,
# you need to comment out "api_interface" and other interfaces from the globals.yml
# and specify like below:
#compute01 neutron_external_interface=eth0 api_interface=em1 tunnel_interface=em1
[storage]
storage01 neutron_external_interface=enp10s0 network_interface=enp1s0
[deployment]
localhost ansible_connection=local
[baremetal:children]
control
network
compute
storage
monitoring
[tls-backend:children]
control
# You can explicitly specify which hosts run each project by updating the
# groups in the sections below. Common services are grouped together.
[common:children]
control
network
compute
storage
monitoring
...
Activate Kolla-Ansible Virtual Environment
Activate your respective virtual environment;
source ~/kolla-ansible/bin/activateTest Connectivity to the Node
Execute the Ansible command below to check the reachability of node in your inventory using the Ansible ping module.
ansible -i multinode -m ping compute02Sample output;
compute02 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python3"
},
"changed": false,
"ping": "pong"
}
Bootstrap the new compute node
You need to bootstrap your server with kolla deploy dependencies by running the command below.
kolla-ansible -i <inventory> bootstrap-servers [ --limit <limit> ]Replace the <inventory> with your inventory file and <limit> with the compute node hostname defined in the inventory.
Be cautious about re-bootstrapping a cloud that has already been boostrapped. See some considerations for reboostrapping.
Thus, our command will look like;
kolla-ansible -i multinode bootstrap-servers --limit compute02If you are adding multiple compute nodes;
kolla-ansible -i multinode bootstrap-servers --limit compute02,compute03,compute0NSample output;
Bootstrapping servers : ansible-playbook -e @/etc/kolla/globals.yml -e @/etc/kolla/passwords.yml -e CONFIG_DIR=/etc/kolla --limit compute02 -e kolla_action=bootstrap-servers /home/kifarunix/kolla-ansible/share/kolla-ansible/ansible/kolla-host.yml --inventory multinode

Deploy Docker Containers for Required Services on the new Node
Next, deploy Docker containers for the required services on the new hosts.
To begin with, download the container images into the host
kolla-ansible -i multinode pull --limit compute02When the command completes, you can list the container images on the node.
You can login to the node and check list images;
docker imagesor just list them using ansible from the control node;
ansible -i multinode -m raw -a "docker images" compute02Sample output;

Nova-compute service is running.
Launch An Instance to Check if it boots on New Compute Node
You can launch an instance just to check if it is going to boot from the new compute node. As you can see above, the new node has no instances running on it at them moment.
Kindly note that compute nodes use the nova-scheduler service to determine how to dispatch compute requests. For example, the nova-scheduler service determines on which host or node a VM should launch. So sometimes, unless you specify the respective node you want to boot an instance from, the vm will be booted from the random nodes as long as they have resources to support those instances.
So, let’s try to randomly boot an instance from the command line;
source $HOME/kolla-ansible/bin/activatesource /etc/kolla/admin-openrc.shGet the images;

--image jammy \

--wait \
curious_lewin
This command creates a new server with the specified image, hardware configuration, availability zone, network interface, and name. It waits for the server creation process to finish before returning control to the user.
Here’s a breakdown of the command and what it does:
--image jammy: Specifies the image (virtual machine template) to be used for the new server. In this case, it’s using an image named “jammy.”--flavor mini: Specifies the flavor (hardware configuration) for the new server. The “mini” flavor likely represents a predefined set of CPU, memory, and storage resources.--availability-zone nova: Explicitly specifies the availability zone in which the new server will be placed. The availability zone is named “nova” in this case. If you dont specify, nova, which is always the default will be used.--nic net-id=<network-id>: Configures the network interface of the new server. It connects the server to a specific network identified by its network ID. Thenet-idparameter is obtained using a combination of commands, whereopenstack network listlists the available networks,grep -i demo_netsearches for a network named “demo_net,” andawk '{print $2}'extracts the network ID.--wait: Instructs OpenStack to wait for the server creation process to complete and the server to be in a running state before returning.curious_lewin: Specifies the name to assign to the new server. In this case, the server is given the name “curious_lewin.”
