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.

  1. Get a clean Ubuntu 20.04 VM (see the DevStack installation instructions for more details). DevStack "takes over". Don't use your desktop!

  2. Clone DevStack inside the VM

    $ git clone https://opendev.org/openstack/devstack.git
  3. Move to devstack directory

    $ cd devstack
  4. Create a local.conf config file

    ../../../contrib/vagrant/local.conf

  5. Run DevStack

    $ ./stack.sh
  6. See the status of all Designate processes

    $ sudo systemctl status devstack@designate-*.service

    See the Using Systemd in DevStack home page for more options.

  7. Querying Logs

    $ sudo journalctl -f --unit devstack@designate-*.service

    See the Querying Logs home page for more options.

  8. Load credentials into the shell

    $ 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

    $ openstack zone create --email admin@example.net example.net.
