Kolla-CLI

The Kolla-CLI project provides the ability to more easily manage Kolla-Ansible deployments. It provides both a CLI and a python API that you can use to configure and deploy OpenStack using Kolla-Ansible.

Kolla-Ansible requires that hosts, groups, and services are specified in an inventory file. With Kolla-CLI, you can add/remove hosts, change group associations, etc from the CLI or API. Kolla-Ansible also maintains passwords and various configuration variables in a variety of global, group and host files. With Kolla-CLI, you can now view and change these from the CLI/API.

Finally, Kolla-CLI provides commands to setup the SSH keys on hosts, run deployments and perform upgrades.

Installing

The installation process below assumes that the kolla-ansible repository exists at the same level as the kolla-cli repository. This is made clear in the cli_setup.py script which makes a relative '../' reference to the kolla-ansible repository. If your kolla-ansible directory is somewhere else then that location can be passed as an argument to the cli_setup.py script. The location on the system where the kolla-cli expects the kolla-ansible files to be and installs them to can be tweaked by setting the KOLLA_HOME and KOLLA_ETC environment variables before running the cli_setup.py script, and while running the kolla-cli command itself. The default value for KOLLA_HOME is /usr/share/kolla-ansible and the default value for KOLLA_ETC is /etc/kolla.

The following steps can be used to build / run the kolla-cli

• install ansible and docker
• virtualenv .venv
• . .venv/bin/activate
• pip install -r requirements.txt
• python setup.py install
• python ./cli_setup.py
• kolla-cli

At that point you will be dropped into the kollacli shell where you can run commands like help or ? to see what commands are available and any of the sub commands can be executed directly.

Alternately you can not use the shell and just execute commands directly via kollacli host add, etc.

If you make changes to the i18n strings (denoted by methods like _("message")) make sure to re-generate the i18n files with the python setup.py extract_messages command and check in the files generated in openstack-kollacli.

API

To use the API, import the ClientAPI into your module:

from kolla_cli.api.client import ClientApi

Then define a global:

CLIENT = ClientApi()

And then you can use that global to execute API commands, for example, to add a host to the inventory:

CLIENT.host_add(['host_name'])

Generating Documentation

We use Sphinx to maintain the documentation. You can install Sphinx using pip.

$ pip install -U Sphinx

In addition to Sphinx you will also need the following requirements (covered by doc/requirements.txt):

$ pip install openstackdocstheme reno 'reno[sphinx]'

The source code of the documentation are under doc, you can generate the html files using the following command. If the generation succeeds,a build/html dir will be created under doc.

$ cd doc
$ make html

Now you can serve the documentation at http://localhost:8080 as a simple website.

$ cd build/html
$ python -m SimpleHTTPServer 8080
