Recently we updated our test jobs so that all of them use the `deploy-env` Ansible role which utilizes the Kubeadm to deploy the test Kubernetes cluster. The role works for both multi-node and single-node environments. Although the deployment of Kubernetes itself is out of scope of Openstack-Helm, we recommen using this role to deploy test and development Kubernetes clusters. So at the moment there is no need to provide different sets of tools single-node and multi-node test envs. Now this is a matter of the Ansible inventory file. Also the deployment procedure of OpenStack on top of Kubernetes using Helm is the same for multi-node and single-node clusters because it only relies on the Kubernetes API. We will be improving the `deploy-env` role even futher and we will be cleaning up the deployment scripts and the documentation so to provide a clear experience for the Openstack-Helm users.

Deploy OpenStack
|
|
================
|
|
|
|
Now we are ready for the deployment of OpenStack components.
|
|
Some of them are mandatory while others are optional.
|
|
|
|
Keystone
|
|
--------
|
|
|
|
OpenStack Keystone is the identity and authentication service
|
|
for the OpenStack cloud computing platform. It serves as the
|
|
central point of authentication and authorization, managing user
|
|
identities, roles, and access to OpenStack resources. Keystone
|
|
ensures secure and controlled access to various OpenStack services,
|
|
making it an integral component for user management and security
|
|
in OpenStack deployments.
|
|
|
|
This is a ``mandatory`` component of any OpenStack cluster.
|
|
|
|
To deploy the Keystone service run the script `keystone.sh`_
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/osh/openstack-helm
|
|
./tools/deployment/component/keystone/keystone.sh
|
|
|
|
|
|
Heat
|
|
----
|
|
|
|
OpenStack Heat is an orchestration service that provides templates
|
|
and automation for deploying and managing cloud resources. It enables
|
|
users to define infrastructure as code, making it easier to create
|
|
and manage complex environments in OpenStack through templates and
|
|
automation scripts.
|
|
|
|
Here is the script `heat.sh`_ for the deployment of Heat service.
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/osh/openstack-helm
|
|
./tools/deployment/component/heat/heat.sh
|
|
|
|
Glance
|
|
------
|
|
|
|
OpenStack Glance is the image service component of OpenStack.
|
|
It manages and catalogs virtual machine images, such as operating
|
|
system images and snapshots, making them available for use in
|
|
OpenStack compute instances.
|
|
|
|
This is a ``mandatory`` component.
|
|
|
|
The Glance deployment script is here `glance.sh`_.
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/osh/openstack-helm
|
|
./tools/deployment/component/glance/glance.sh
|
|
|
|
Placement, Nova, Neutron
|
|
------------------------
|
|
|
|
OpenStack Placement is a service that helps manage and allocate
|
|
resources in an OpenStack cloud environment. It helps Nova (compute)
|
|
find and allocate the right resources (CPU, memory, etc.)
|
|
for virtual machine instances.
|
|
|
|
OpenStack Nova is the compute service responsible for managing
|
|
and orchestrating virtual machines in an OpenStack cloud.
|
|
It provisions and schedules instances, handles their lifecycle,
|
|
and interacts with underlying hypervisors.
|
|
|
|
OpenStack Neutron is the networking service that provides network
|
|
connectivity and enables users to create and manage network resources
|
|
for their virtual machines and other services.
|
|
|
|
These three services are ``mandatory`` and together constitue
|
|
so-called ``compute kit``.
|
|
|
|
To set up the compute service, the first step involves deploying the
|
|
hypervisor backend using the `libvirt.sh`_ script. By default, the
|
|
networking service is deployed with OpenvSwitch as the networking
|
|
backend, and the deployment script for OpenvSwitch can be found
|
|
here: `openvswitch.sh`_. And finally the deployment script for
|
|
Placement, Nova and Neutron is here: `compute-kit.sh`_.
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/osh/openstack-helm
|
|
./tools/deployment/component/compute-kit/openvswitch.sh
|
|
./tools/deployment/component/compute-kit/libvirt.sh
|
|
./tools/deployment/component/compute-kit/compute-kit.sh
|
|
|
|
Cinder
|
|
------
|
|
|
|
OpenStack Cinder is the block storage service component of the
|
|
OpenStack cloud computing platform. It manages and provides persistent
|
|
block storage to virtual machines, enabling users to attach and detach
|
|
persistent storage volumes to their VMs as needed.
|
|
|
|
To deploy the OpenStack Cinder service use the script `cinder.sh`_
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/osh/openstack-helm
|
|
./tools/deployment/component/cinder/cinder.sh
