How to install DNS with DevStack
================================
The Designate source code contains a DevStack plugin that allows to deploy
an OpenStack installation with the DNS service enabled.
Instructions
~~~~~~~~~~~~
.. note::
If you want to use local sources for development then you should consider
using the contrib/vagrant folder in the
`repository <https://opendev.org/openstack/designate>`_.
1. Get a clean Ubuntu 20.04 VM (see the `DevStack installation
instructions`_ for more details). DevStack "takes over". Don't use
your desktop!
.. _`DevStack installation instructions`: https://docs.openstack.org/devstack/latest/#install-linux
2. Clone DevStack inside the VM
.. code-block:: console
$ git clone https://opendev.org/openstack/devstack.git
3. Move to ``devstack`` directory
.. code-block:: console
$ cd devstack
4. Create a `local.conf` config file
.. literalinclude:: ../../../contrib/vagrant/local.conf
:language: bash
5. Run DevStack
.. code-block:: console
$ ./stack.sh
6. See the status of all Designate processes
.. code-block:: console
$ sudo systemctl status devstack@designate-*.service
See the `Using Systemd in DevStack`_ home page for more options.
.. _`Using Systemd in DevStack`: https://docs.openstack.org/devstack/latest/systemd.html
7. Querying Logs
.. code-block:: console
$ sudo journalctl -f --unit devstack@designate-*.service
See the `Querying Logs`_ home page for more options.
.. _`Querying Logs`: https://docs.openstack.org/devstack/latest/systemd.html#querying-logs
8. Load credentials into the shell
.. code-block:: console
$ export OS_CLOUD=devstack-admin # For the admin user, admin project
$ export OS_CLOUD=devstack # For the demo user, demo project
9. Try out the openstack client
.. code-block:: console
$ openstack zone create --email admin@example.net example.net.
