# Working With Quickstart Extras¶

There are several additional roles compatible with tripleo-quickstart that extend the capability of TripleO Quickstart beyond setting up the basic deployment structure on a virthost. There are roles for doing end-to-end deployments and deployment validation both for virthost and baremetal machines and a few auxiliary roles for doing CI related tasks.

These roles are hosted at the tripleo-quickstart-extras repository.

Extras can be installed manually using Python setuptools, but quickstart.sh provides an automated system for building the Python virtual environment and pulling in additional dependencies using pip install and the quickstart-extras-requirements.txt file.

To run a full end-to-end deployment including verification, add these command line options when running quickstart.sh:

--tags all


See quickstart.sh --help for a full list of options, but here is a full example using some common developer settings:

./quickstart.sh --requirements quickstart-extras-requirements.txt \
--tags all \
--teardown all \
--release master \
--no-clone \
--clean \
--config config/general_config/pacemaker.yml \
virthost.example.com


This uses the currently cloned tripleo-quickstart repository instead of re-cloning it in the working directory, doing the following:

• deletes the working directory at ~/.quickstart
• this forces quickstart to create the virtual environment and redownload all the requirements fresh, including the extras
• it does a thorough cleanup of the virthost.example.com machine, reinstalling libvirt, deleting networks and VMs
• deploys both the undercloud and the overcloud
• verifies the deployed environment in a quick and simple way

## Developing new roles¶

Developing new roles is possible by submitting new reviews for this repo, or creating it anywhere and adding a reference to the end of the quickstart-extras-requirements.txt file:

git+https://github.com/organization/ansible-role-example.git/#egg=ansible-role-example


To import a role that you are developing locally use the following syntax:

file:///home/user/folder/ansible-role-example/#egg=ansible-role-example


Once added to the role requirements file quickstart.sh will automatically install the specified extras into the local working directory, which is a Python virtual environment managed by quickstart. By default this environment will be placed in ~/.quickstart but you can specify its location using the --working-dir argument.

To invoke quickstart with a playbook of your own or from a preexisting role run the following command:

./quickstart.sh --requirements $REQUIREMENTS --playbook playbook.yml \ --working-dir$WORKSPACE $VIRTHOST  If the virtual environment in $WORKSPACE has not already been setup then quickstart.sh will create it and install all the extras. This will only happen the first time you run quickstart against that workspace. If you need to add more dependencies or update existing ones, source the virtual and then run the setup.py for the role:

source $WORKSPACE/bin/activate cd$ROLE
python setup.py install


Deleting the environment and allowing quickstart to regenerate it entirely also works. Both $REQUIREMENTS and $WORKSPACE should be absolute paths.

The playbook quickstart-extras.yml is the most complete playbook offered by default, it will perform all tasks up to deployment and testing the overcloud using this same method.

While editing existing playbooks is a good way to become familiar with quickstart for actual usage it’s suggested that you include a default playbook at the start of your own instead of duplicating it in your extra. The example shown below would provide a fully functioning cloud for the rest of your playbook to run against:

- name: Setup the cloud
include: quickstart-extras.yml
