Installation Guide

Tuskar source code should be pulled directly from git:

git clone https://git.openstack.org/openstack/tuskar

Dependencies

Setting up a local environment for development can be done with tox:

# install prerequisites
* Ubuntu/Debian:
$ sudo apt-get install python-dev swig libssl-dev python-pip libmysqlclient-dev libxml2-dev libxslt-dev gcc
* Fedora/RHEL:
$ sudo yum install python-devel swig openssl-devel python-pip mysql-devel libxml2-devel libxslt-devel gcc
# Note that as of Fedora 19, you need to use the community
  upstream for mysql, called mariadb-devel

$ sudo pip install virtualenv setuptools-git flake8 tox

You may need to downgrade tox, due to an issue described here: https://bugs.launchpad.net/openstack-ci/+bug/1274135:

$ sudo pip uninstall --yes tox virtualenv
$ sudo rm -rf /tmp/pip-build-* /usr/local/lib/python2.7/dist-packages/tox \
      /usr/local/lib/python2.7/dist-packages/virtualenv \
      /usr/local/bin/tox /usr/local/bin/virtualenv
$ sudo pip install -U tox==1.6.1 virtualenv==1.10.1

Now create your virtualenv:

$ cd <your_src_dir>/tuskar
$ tox -e py27

Note: if pip install fails due to an outdated setuptools, you can try to update it first:

$ sudo pip install --upgrade setuptools

Configuration

Copy the sample configuration file:

$ cp etc/tuskar/tuskar.conf.sample etc/tuskar/tuskar.conf

Edit the config file and uncomment the heat_keystone section at the bottom:

[heat_keystone]

username = heat
password = heat
tenant_name = admin
auth_url = http://localhost:35357/v2.0
insecure = True

Note: replace these values with credentials for our undercloud OpenStack. If you're using Devstack, the username and password are printed out when stack.sh finishes its job.

You will need a local checkout of the tripleo-heat-templates. Uncomment the configuration entry that is defined for this purpose: tht_local_dir should point to your local copy of the tripleo-heat-templates:

tht_local_dir = /etc/tuskar/tripleo-heat-templates/

At tuskar startup, if the directory specified by tht_local_dir in your tuskar.conf doesn't exist startup will fail. You can clone the templates:

(sudo) git clone https://git.openstack.org/openstack/tripleo-heat-templates /etc/tuskar/tripleo-heat-templates/

We need to initialise the database schema:

# activate the virtualenv
$ source .tox/py27/bin/activate

# if you delete tuskar.sqlite this will force creation of tables again - e.g.
# if you added a new resource table definitions etc in an existing migration
# file
$ tuskar-dbsync --config-file etc/tuskar/tuskar.conf

You can verify this was successful (in addition to seeing no error output) with:

$ sqlite3 tuskar/openstack/common/db/tuskar.sqlite .schema

Then, launch the app:

$ tuskar-api --config-file etc/tuskar/tuskar.conf

Assuming this is your first time running with a new database, you should populate the DB with some initial data:

$ python tools/initial_data.py

This will create four Overcloud Roles. You can then verify that everything worked by running:

$ curl -v -X GET -H 'Accept: application/json' http://0.0.0.0:8585/v1/overcloud_roles/ | python -mjson.tool

This command should return JSON for four Overcloud Roles.

Running Tuskar API

Whenever you want to run the API again, just switch to the virtualenv and run tuskar-api command:

$ source .tox/py27/bin/activate
$ tuskar-api --config-file etc/tuskar/tuskar.conf
