Install OpenStack
=================
In the :doc:`previous section <install-juju>`, we installed Juju and created a
Juju controller and model. We are now going to use Juju to install OpenStack
itself.
Despite the length of this page, only two distinct Juju commands will be
employed: :command:`juju deploy` and :command:`juju add-relation`. You may want
to review these pertinent sections of the Juju documentation before continuing:
* `Deploying applications`_
* `Deploying to specific machines`_
* `Managing relations`_
.. TODO
Cloud topology section goes here (modelled on openstack-base README)
This page will show how to install a minimal non-HA OpenStack cloud. See
`Infrastructure high availability`_ for guidance on that subject.
OpenStack release
-----------------
.. TEMPLATE (alternate between the following two paragraphs each six months)
As the :doc:`Overview <install-overview>` of the Installation section
states, OpenStack Xena will be deployed atop Ubuntu 20.04 LTS (Focal) cloud
nodes. In order to achieve this a cloud archive release of
'cloud:focal-xena' will be used during the install of each OpenStack
application. Note that some applications are not part of the OpenStack
project per se and therefore do not apply (exceptionally, Ceph applications
do use this method). Not using a more recent OpenStack release in this way
will result in an Ussuri deployment (i.e. Ussuri is in the Ubuntu package
archive for Focal).
As the :doc:`Overview <install-overview>` of the Installation section states,
OpenStack Yoga will be deployed atop Ubuntu 22.04 LTS (Jammy) cloud nodes. In
order to achieve this the default package archive ("distro") for the cloud
nodes will be used during the install of each OpenStack application. Note that
some applications are not part of the OpenStack project per se and therefore do
not apply (exceptionally, Ceph applications do use this method).
See :ref:`cg:perform_the_upgrade` in the Charm Guide for more details on cloud
archive releases and how they are used when upgrading OpenStack.
.. important::
The chosen OpenStack release may impact the installation and configuration
instructions. **This guide assumes that OpenStack Yoga is being deployed.**
Installation progress
---------------------
There are many moving parts involved in a charmed OpenStack install. During
much of the process there will be components that have not yet been satisfied,
which will cause error-like messages to be displayed in the output of the
:command:`juju status` command. Do not be alarmed. Indeed, these are
opportunities to learn about the interdependencies of the various pieces of
software. Messages such as **Missing relation** and **blocked** will vanish
once the appropriate applications and relations have been added and processed.
.. tip::
One convenient way to monitor the installation progress is to have command
:command:`watch -n 5 -c juju status --color` running in a separate terminal.
Deploy OpenStack
----------------
Assuming you have precisely followed the instructions on the :doc:`Install Juju
<install-juju>` page, you should now have a Juju controller called
'maas-controller' and an empty Juju model called 'openstack'. Change to that
context now:
.. code-block:: none
juju switch maas-controller:openstack
In the following sections, the various OpenStack components will be added to
the 'openstack' model. Each application will be installed from the online
`Charmhub`_ and many will have configuration options specified via a YAML file.
.. note::
You do not need to wait for a Juju command to complete before issuing
further ones. However, it can be very instructive to see the effect one
command has on the current state of the cloud.
Ceph OSD
~~~~~~~~
The ceph-osd application is deployed to four nodes with the `ceph-osd`_ charm.
The name of the block devices backing the OSDs is dependent upon the hardware
on the nodes. All possible devices across the nodes should be given as the
value for the ``osd-devices`` option (space-separated). Here, we'll be using
the same devices on each node: ``/dev/vdb`` and ``/dev/vdc``. File
``ceph-osd.yaml`` contains the configuration:
.. code-block:: yaml
ceph-osd:
osd-devices: /dev/vdb /dev/vdc
source: distro
To deploy the application we'll make use of the 'compute' tag that we placed on
each of these nodes on the :doc:`Install MAAS <install-maas>` page:
.. code-block:: none
juju deploy -n 4 --series jammy --channel quincy/stable --config ceph-osd.yaml --constraints tags=compute ceph-osd
If a message from a ceph-osd unit like "Non-pristine devices detected" appears
in the output of :command:`juju status` you will need to use actions
``zap-disk`` and ``add-disk`` that come with the ceph-osd charm. The
``zap-disk`` action is destructive in nature. Only use it if you want to purge
the disk of all data and signatures for use by Ceph.
.. note::
Since ceph-osd was deployed on four nodes and there are only four nodes
available in this environment, the usage of the 'compute' tag is not
strictly necessary. A tag can help if there are a surplus of nodes however.
Nova Compute
~~~~~~~~~~~~
The nova-compute application is deployed to three nodes with the
`nova-compute`_ charm. File ``nova-compute.yaml`` contains the configuration:
.. code-block:: yaml
nova-compute:
config-flags: default_ephemeral_format=ext4
enable-live-migration: true
enable-resize: true
migration-auth-type: ssh
virt-type: qemu
openstack-origin: distro
The nodes must be targeted by machine ID since there are no more free Juju
machines (MAAS nodes) available. This means we're placing multiple services on
our nodes. We've chosen machines 1, 2, and 3. To deploy:
.. code-block:: none
juju deploy -n 3 --to 1,2,3 --series jammy --channel yoga/stable --config nova-compute.yaml nova-compute
.. note::
The 'nova-compute' charm is designed to support one image format type per
application at any given time. Changing format (see charm option
``libvirt-image-backend``) while existing instances are using the prior
format will require manual image conversion for each instance. See bug `LP
#1826888`_.
MySQL InnoDB Cluster
~~~~~~~~~~~~~~~~~~~~
MySQL InnoDB Cluster always requires at least three database units. They will
be containerised on machines 0, 1, and 2. To deploy:
.. code-block:: none
juju deploy -n 3 --to lxd:0,lxd:1,lxd:2 --series jammy --channel 8.0/stable mysql-innodb-cluster
Vault
~~~~~
Vault is necessary for managing the TLS certificates that will enable encrypted
communication between cloud applications. It will be containerised on machine
3. To deploy:
.. code-block:: none
juju deploy --to lxd:3 --series jammy --channel 1.7/stable vault
This is the first application to be joined with the cloud database that was set
up in the previous section. The process is:
#. create an application-specific instance of mysql-router (a subordinate)
#. add a relation between the mysql-router instance and the database
#. add a relation between the mysql-router instance and the application
The combination of steps 2 and 3 joins the application to the cloud database.
Here are the corresponding commands for Vault:
.. code-block:: none
juju deploy --channel 8.0/stable mysql-router vault-mysql-router
juju add-relation vault-mysql-router:db-router mysql-innodb-cluster:db-router
juju add-relation vault-mysql-router:shared-db vault:shared-db
Vault must now be initialised and unsealed. The vault charm will also need to
be authorised to carry out certain tasks. These steps are covered in the `vault
charm`_ documentation. Perform them now.
Provide Vault with a CA certificate so it can issue certificates to cloud API
services. This is covered on the :ref:`Managing TLS certificates
<add_ca_certificate>` page. Do this now.
Once the above is completed the Unit section output to command :command:`juju
status` should look similar to this:
.. code-block:: console

Cloud applications are TLS-enabled via the ``vault:certificates`` relation.
Below we start with the cloud database. Although the latter has a self-signed
certificate, it is recommended to use the one signed by Vault's CA:
.. code-block:: none
juju add-relation mysql-innodb-cluster:certificates vault:certificates
.. _neutron_networking:
Neutron networking
~~~~~~~~~~~~~~~~~~
Neutron networking is implemented with four applications:
* neutron-api
* neutron-api-plugin-ovn (subordinate)
* ovn-central
* ovn-chassis (subordinate)
File ``neutron.yaml`` contains the configuration necessary for three of them:
.. code-block:: yaml
ovn-chassis:
bridge-interface-mappings: br-ex:enp1s0
ovn-bridge-mappings: physnet1:br-ex
neutron-api:
neutron-security-groups: true
flat-network-providers: physnet1
openstack-origin: distro
ovn-central:
source: distro
The ``bridge-interface-mappings`` setting impacts the OVN Chassis and refers to
a mapping of OVS bridge to network interface. As described in the :ref:`Create
OVS bridge <ovs_bridge>` section on the :doc:`Install MAAS <install-maas>`
page, it is 'br-ex:enp1s0'.
.. note::
To use hardware addresses (as opposed to an interface name common to all
four nodes) the ``bridge-interface-mappings`` option can be expressed in
this way (substitute in your own values):
.. code-block:: yaml
bridge-interface-mappings: >-
br-ex:52:54:00:03:01:01
br-ex:52:54:00:03:01:02
br-ex:52:54:00:03:01:03
br-ex:52:54:00:03:01:04
The ``flat-network-providers`` setting enables the Neutron flat network
provider used in this example scenario and gives it the name of 'physnet1'. The
flat network provider and its name will be referenced when we :ref:`Set up
public networking <public_networking>` on the next page.
The ``ovn-bridge-mappings`` setting maps the data-port interface to the flat
network provider.
The main OVN application is ovn-central and it requires at least three units.
They will be containerised on machines 0, 1, and 2. To deploy:
.. code-block:: none
juju deploy -n 3 --to lxd:0,lxd:1,lxd:2 --series jammy --channel 22.03/stable --config neutron.yaml ovn-central
The neutron-api application will be containerised on machine 1:
.. code-block:: none
juju deploy --to lxd:1 --series jammy --channel yoga/stable --config neutron.yaml neutron-api
Deploy the subordinate charm applications:
.. code-block:: none
juju deploy --channel yoga/stable neutron-api-plugin-ovn
juju deploy --channel 22.03/stable --config neutron.yaml ovn-chassis
Add the necessary relations:
.. code-block:: none
juju add-relation neutron-api-plugin-ovn:neutron-plugin neutron-api:neutron-plugin-api-subordinate
juju add-relation neutron-api-plugin-ovn:ovsdb-cms ovn-central:ovsdb-cms
juju add-relation ovn-chassis:ovsdb ovn-central:ovsdb
juju add-relation ovn-chassis:nova-compute nova-compute:neutron-plugin

juju add-relation neutron-api-plugin-ovn:certificates vault:certificates
juju add-relation ovn-central:certificates vault:certificates
juju add-relation ovn-chassis:certificates vault:certificates
Join neutron-api to the cloud database:
.. code-block:: none
juju deploy --channel 8.0/stable mysql-router neutron-api-mysql-router
juju add-relation neutron-api-mysql-router:db-router mysql-innodb-cluster:db-router
juju add-relation neutron-api-mysql-router:shared-db neutron-api:shared-db
Keystone
~~~~~~~~
The keystone application will be containerised on machine 0 with the
`keystone`_ charm. To deploy:
.. code-block:: none
juju deploy --to lxd:0 --series jammy --channel yoga/stable keystone
Join keystone to the cloud database:
.. code-block:: none
juju deploy --channel 8.0/stable mysql-router keystone-mysql-router
juju add-relation keystone-mysql-router:db-router mysql-innodb-cluster:db-router
juju add-relation keystone-mysql-router:shared-db keystone:shared-db
Two additional relations can be added at this time:
.. code-block:: none
juju add-relation keystone:identity-service neutron-api:identity-service
juju add-relation keystone:certificates vault:certificates
RabbitMQ
~~~~~~~~
The rabbitmq-server application will be containerised on machine 2 with the
`rabbitmq-server`_ charm. To deploy:
.. code-block:: none
juju deploy --to lxd:2 --series jammy --channel 3.9/stable rabbitmq-server
Two relations can be added at this time:
.. code-block:: none
juju add-relation rabbitmq-server:amqp neutron-api:amqp
juju add-relation rabbitmq-server:amqp nova-compute:amqp

Nova cloud controller
~~~~~~~~~~~~~~~~~~~~~
The nova-cloud-controller application, which includes nova-scheduler, nova-api,
and nova-conductor services, will be containerised on machine 3 with the
`nova-cloud-controller`_ charm. File ``ncc.yaml`` contains the configuration:
.. code-block:: yaml

Two additional relations are required:
.. code-block:: none
juju add-relation openstack-dashboard:identity-service keystone:identity-service
juju add-relation openstack-dashboard:certificates vault:certificates

~~~~~~
The glance application will be containerised on machine 3 with the `glance`_
charm. To deploy:
.. code-block:: none
juju deploy --to lxd:3 --series jammy --channel yoga/stable glance
Join glance to the cloud database:

Ceph monitor
~~~~~~~~~~~~
The ceph-mon application will be containerised on machines 0, 1, and 2 with the
`ceph-mon`_ charm. File ``ceph-mon.yaml`` contains the configuration:
.. code-block:: yaml
ceph-mon:
expected-osd-count: 4
monitor-count: 3
source: distro
To deploy:
.. code-block:: none
juju deploy -n 3 --to lxd:0,lxd:1,lxd:2 --series jammy --channel quincy/stable --config ceph-mon.yaml ceph-mon
Three relations can be added at this time:
.. code-block:: none
juju add-relation ceph-mon:osd ceph-osd:mon
juju add-relation ceph-mon:client nova-compute:ceph
juju add-relation ceph-mon:client glance:ceph
For the above relations,
* The nova-compute:ceph relation makes Ceph the storage backend for Nova
non-bootable disk images. The nova-compute charm option
``libvirt-image-backend`` must be set to 'rbd' for this to take effect.
* The ``glance:ceph`` relation makes Ceph the storage backend for Glance.
Cinder
~~~~~~
The cinder application will be containerised on machine 1 with the `cinder`_
charm. File ``cinder.yaml`` contains the configuration:
.. code-block:: yaml
cinder:
block-device: None
glance-api-version: 2
openstack-origin: distro
To deploy:
.. code-block:: none
juju deploy --to lxd:1 --series jammy --channel yoga/stable --config cinder.yaml cinder
Join cinder to the cloud database:
.. code-block:: none
juju deploy --channel 8.0/stable mysql-router cinder-mysql-router
juju add-relation cinder-mysql-router:db-router mysql-innodb-cluster:db-router
juju add-relation cinder-mysql-router:shared-db cinder:shared-db
Five additional relations can be added at this time:
.. code-block:: none
juju add-relation cinder:cinder-volume-service nova-cloud-controller:cinder-volume-service
juju add-relation cinder:identity-service keystone:identity-service
juju add-relation cinder:amqp rabbitmq-server:amqp
juju add-relation cinder:image-service glance:image-service
juju add-relation cinder:certificates vault:certificates
The above ``glance:image-service`` relation will enable Cinder to consume the
Glance API (e.g. making Cinder able to perform volume snapshots of Glance
images).
Like Glance, Cinder will use Ceph as its storage backend (hence ``block-device:
None`` in the configuration file). This will be implemented via the
`cinder-ceph`_ subordinate charm:
.. code-block:: none
juju deploy --channel yoga/stable cinder-ceph
Three relations need to be added:
.. code-block:: none
juju add-relation cinder-ceph:storage-backend cinder:storage-backend
juju add-relation cinder-ceph:ceph ceph-mon:client
juju add-relation cinder-ceph:ceph-access nova-compute:ceph-access
Ceph RADOS Gateway
~~~~~~~~~~~~~~~~~~
The Ceph RADOS Gateway will be deployed to offer an S3 and Swift compatible
HTTP gateway. This is an alternative to using OpenStack Swift.
The ceph-radosgw application will be containerised on machine 0 with the
`ceph-radosgw`_ charm. To deploy:
.. code-block:: none
juju deploy --to lxd:0 --series jammy --channel quincy/stable ceph-radosgw
A single relation is needed:
.. code-block:: none
juju add-relation ceph-radosgw:mon ceph-mon:radosgw
.. COMMENT
At the time of writing a jammy-aware ntp charm was not available.
NTP

The final component is an NTP client to keep the time on each cloud node
synchronised. This is done with the `ntp`_ subordinate charm. To deploy:
.. code-block:: none
juju deploy ntp
The below relation will add an ntp unit alongside each ceph-osd unit, and
thus on each of the four cloud nodes:
.. code-block:: none
juju add-relation ceph-osd:juju-info ntp:juju-info

Final results and dashboard access
----------------------------------
Once all the applications have been deployed and the relations between them
have been added we need to wait for the output of :command:`juju status` to
settle. The final results should be devoid of any error-like messages. Example
output (including relations) for a successful cloud deployment is given
:ref:`here <install_openstack_juju_status>`.
One milestone in the deployment of OpenStack is the first login to the Horizon
dashboard. You will need its IP address and the admin password.
Obtain the address in this way:
.. code-block:: none
juju status --format=yaml openstack-dashboard | grep public-address | awk '{print $2}' | head -1
In this example, the address is '10.0.0.178'.
The password can be queried from Keystone:
.. code-block:: none
juju run --unit keystone/leader leader-get admin_passwd
The dashboard URL then becomes:
**http://10.0.0.178/horizon**
The final credentials needed to log in are:
| User Name: **admin**
| Password: ********************
| Domain: **admin_domain**
|
Once logged in you should see something like this:
.. figure:: ./media/install-openstack_horizon.png
:scale: 70%
:alt: Horizon dashboard
VM consoles
~~~~~~~~~~~
Enable a remote access protocol such as novnc (or spice) if you want to connect
to VM consoles from within the dashboard:
.. code-block:: none
juju config nova-cloud-controller console-access-protocol=novnc
Next steps
----------
You have successfully deployed OpenStack using Juju and MAAS. The next step is
to render the cloud functional for users. This will involve setting up
networks, images, and a user environment. Go to :doc:`Configure OpenStack
<configure-openstack>` now.
