Deploying Adjutant in Devstack

This is a guide to setting up Adjutant in a running Devstack environment close to how we have been running it for development purposes.

This guide assumes you are running this in a clean ubuntu 16.04 virtual machine with sudo access.

Deploy Devstack

Grab the Devstack repo:

git clone https://opendev.org/openstack/devstack

And then define a basic localrc file with the password set and place that in the devstack folder (adjutant’s default conf assumes ‘openstack’ as the admin password):

ADMIN_PASSWORD=openstack
MYSQL_PASSWORD=openstack
DATABASE_PASSWORD=openstack
RABBIT_PASSWORD=openstack
SERVICE_PASSWORD=openstack

Run the devstack build:

./devstack/stack.sh

Provided your VM has enough ram to handle a devstack install this should take a while, but go smoothly. Ideally give your VM 5gb or more of ram, any less can cause the devstack build to fail.

Deploy Adjutant

Grab the Adjutant repo:

git clone https://opendev.org/openstack/adjutant

Then you’ll want to setup a virtual environment:

cd adjutant
virtualenv venv
source venv/bin/activate

Once that is done you can install Adjutant and its requirements:

pip install -r requirements.txt
python setup.py develop

If you prefer you can install it fully, but using develop instead allows you update the Adjutant code and have the service reflect that without rerunning the install.

Configure Adjutant

Most of the default conf values should work fine against devstack, but one thing that you will need to change is the uuid for the public network in DEFAULT_ACTION_SETTINGS for the actions NewDefaultNetworkAction and NewProjectDefaultNetworkAction. If you don’t set this correctly, then signups or tasks using those actions will not be able to correctly create a default network as they cannot find the correct external public network.

On a fresh devstack there is only one public network so to find the public network uuid you can to run:

openstack network show public

And then grab the id value and put that into the Adjutant conf.

Username is email

The example conf for Adjutant is setup with USERNAME_IS_EMAIL = TRUE which works on the assumption that usernames are emails. This is easy to change in the conf, but a fairly useful way of avoiding username clashes. If you set this to False then usernames will be required as well as emails for most tasks that deal with user creation.

Migrating between the two states hasn’t yet been handled entirely, so once you pick a value for USERNAME_IS_EMAIL stick with it, or clear the database inbetween.

Running Adjutant

Still in the Adjutant repo directory, you will now need to run the migrations to build a basic database. By default this will use sqlite3.:

adjutant-api migrate

Now the that the migrations have been setup and the database built run the service from the same directory, and it will revert to using the config file at ‘conf/conf.yaml’:

adjutant-api runserver 0.0.0.0:5050

Note

The port doesn’t matter, but 5050 is a safe bet as it isn’t used by any other DevStack services and we can then safely assume you will be using the same url for the rest of the guide.

Now you have Adjutant running, keep this window open as you’ll want to keep an eye on the console output.

Add Adjutant to Keystone Catalogue

In a new SSH termimal connected to your ubuntu VM setup your credentials as environment variables:

export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_PROJECT_NAME=demo
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_DOMAIN_NAME=default
export OS_AUTH_URL=http://localhost/identity
export OS_IDENTITY_API_VERSION=3
export OS_REGION_NAME=RegionOne

If you used the localrc file as given above, these should work.

Now setup a new service in Keystone for Adjutant and add an endpoint for it:

openstack service create registration --name adjutant
openstack endpoint create adjutant public http://0.0.0.0:5050/v1 --region RegionOne

Adjutant specific roles

To allow certain actions, Adjutant requires two special roles to exist. You can create them as such:

openstack role create project_admin
openstack role create project_mod

Also because Adjutant by default also adds the role, you will want to create ‘heat_stack_owner’ which isn’t by default present in devstack unless you install Heat:

openstack role create heat_stack_owner

Testing Adjutant via the CLI

Now that the service is running, and the endpoint setup, you will want to install the client and try talking to the service:

sudo pip install python-adjutantclient

In this case the client should be safe to install globally with sudo, but you can also install it in the same virtualenv as Adjutant itself, or make a new virtualenv.

Now lets check the status of the service:

openstack adjutant status

What you should get is:

{
    "error_notifications": [],
    "last_completed_task": null,
    "last_created_task": null
}

Seeing as we’ve done nothing to the service yet this is the expected output.

To list the users on your current project (admin users are hidden by default):

openstack project user list

The above action is only possibly for users with the following roles: ‘admin’, ‘project_admin’, ‘project_mod’

Now lets try inviting a new user:

openstack project user invite bob@example.com project_admin

You will then get a note saying your invitation has been sent. You can list your project users again with ‘openstack project user list’ to see your invite.

Now if you look at the log in the Adjutant terminal you should still have open, you will see a print out of the email that would have been sent to bob@example.com. In the email is a line that looks like this:

http://192.168.122.160:8080/token/e86cbfb187d34222ace90845f900893c

Normally that would direct the user to a Horizon dashboard page where they can submit their password.

Since we don’t have that running, your only option is to submit it via the CLI. This is cumbersome, but doable. From that url in your Adjutant output, grab the values after ‘…/token/’. That is bob’s token. You can submit that via the CLI:

openstack admin task token submit <token> <json_data>
openstack admin task token submit e86cbfb187d34222ace90845f900893c '{"password": "123456"}'

Now if you get the user list, you will see bob is now active:

openstack project user list

And also shows up as a user if you do:

openstack user list

And since you are an admin, you can even take a look at the tasks themselves:

openstack admin task list

The topmost one should be your invite, and if you then do a show using that id you can see some details about it:

openstack admin task show <UUID>

Setting Up Adjutant on Horizon

Adjutant has a Horizon UI plugin, the code and setup instructions for it can be found here.

If you do set this up, you will want to edit the default Adjutant conf to so that the TOKEN_SUBMISSION_URL is correctly set to point at your Horizon.
