Included Scripts

Included Scripts

The repository contains several helper scripts to manage gate jobs, install base requirements, and update repository information. Execute these scripts from the root of the repository clone. For example:

$ scripts/<script_name>.sh


The script installs Ansible, including the core and extras module repositories and Galaxy roles.

While there are several configurable environment variables which this script uses, the following are commonly used:

  • ANSIBLE_PACKAGE - The version of Ansible to install.

For example:

$ export ANSIBLE_PACKAGE="ansible==2.1.0"

Installing directly from git is also supported. For example, from the tip of Ansible development branch:

$ export ANSIBLE_PACKAGE="git+"
  • ANSIBLE_ROLE_FILE - The location of a YAML file which ansible-galaxy can consume which specifies which roles to download and install. The default value for this is ansible-role-requirements.yml.

The script also creates the openstack-ansible wrapper tool that provides the variable files to match /etc/openstack_deploy/user_*.yml as arguments to ansible-playbook as a convenience.

The script prepares a host for an All-In-One (AIO) deployment for the purposes of development and gating. The script creates the necessary partitions, directories, and configurations. The script can be configured using environment variables - more details are provided on the All-In-One page.

Development and Testing

Lint Tests

Python coding conventions are tested using PEP8, with the following convention exceptions:

  • F403 - ‘from ansible.module_utils.basic import *’

Testing may be done locally by executing:

tox -e pep8

Bash coding conventions are tested using Bashate, with the following convention exceptions:

  • E003: Indent not multiple of 4. We prefer to use multiples of 2 instead.
  • E006: Line longer than 79 columns. As many scripts are deployed as templates
    and use jinja templating, this is very difficult to achieve. It is still considered a preference and should be a goal to improve readability, within reason.
  • E040: Syntax error determined using bash -n. As many scripts are deployed
    as templates and use jinja templating, this will often fail. This test is reasonably safely ignored as the syntax error will be identified when executing the resulting script.

Testing may be done locally by executing:

tox -e bashate

Ansible is lint tested using ansible-lint.

Testing may be done locally by executing:

tox -e ansible-lint

Ansible playbook syntax is tested using ansible-playbook.

Testing may be done locally by executing:

tox -e ansible-syntax

A consolidated set of all lint tests may be done locally by executing:

tox -e linters

Documentation Build

Documentation is developed in reStructuredText (RST) and compiled into HTML using Sphinx.

Documentation may be built locally by executing:

tox -e docs
tox -e deploy-guide

Release Notes Build

Release notes are generated using the the reno tool and compiled into HTML using Sphinx.

Release notes may be built locally by executing:

tox -e releasenotes


The releasenotes build argument only tests committed changes. Ensure your local changes are committed before running the releasenotes build.


Every commit to the OpenStack-Ansible integrated build is verified by OpenStack-CI through the following jobs:

  • gate-openstack-ansible-releasenotes: This job executes the Release Notes Build.

  • gate-openstack-ansible-docs-ubuntu-xenial: This job executes the Documentation Build.

  • gate-openstack-ansible-linters-ubuntu-xenial: This job executes the Lint Tests.

  • gate-openstack-ansible-openstack-ansible-aio-ubuntu-xenial: where aio is the scenario, ubuntu is the distribution, and xenial is the version of the distribution.

    The same test is executed against multiple distribution versions, and may be executed against multiple distributions and multiple scenarios too.

    This job executes the script which executes a convergence test and then a functional test.

    The convergence test is the execution of an AIO build which aims to test the primary code path for a functional environment. The functional test then executes OpenStack’s Tempest testing suite to verify that the environment that has deployed successfully actually works.

    While this script is primarily developed and maintained for use in OpenStack-CI, it can be used in other environments.

Dependency Updates

The dependencies for OpenStack-Ansible are updated approximately every two weeks through the use of scripts/ This script updates all pinned SHA’s for OpenStack services, OpenStack-Ansible roles, and other python dependencies which are not handled by the OpenStack global requirements management process. This script also updates the statically held templates/files in each role to ensure that they are always up to date. Finally, it also does a minor version increment of the value for openstack_release.

The update script is used as follows:

# change directory to the openstack-ansible checkout
cd ~/code/openstack-ansible

# ensure that the correct branch is checked out
git checkout stable/pike

# ensure that the branch is up to date
git pull

# create the local branch for the update
git checkout -b sha-update

# execute the script for all openstack services
./scripts/ -b stable/pike -o stable/pike

# execute the script for gnocchi
./scripts/ -s playbooks/defaults/repo_packages/gnocchi.yml -b 4.0 -o stable/pike

# the console code should only be updated when necessary for a security fix, or for the OSA master branch
./scripts/ -s playbooks/defaults/repo_packages/nova_consoles.yml -b master

# the testing repositories should not be updated for stable branches as the new tests
# or other changes introduced may not work for older branches
./scripts/ -s playbooks/defaults/repo_packages/openstack_testing.yml -b master

# commit the changes
new_version=$(awk '/^openstack_release/ {print $2}' inventory/group_vars/all/all.yml)
git add --all
git commit -a -m "Update all SHAs for ${new_version}" -m "This patch updates all the roles to the latest available stable
SHA's, copies the release notes from the updated roles into the
integrated repo, updates all the OpenStack Service SHA's, and
updates the appropriate python requirements pins.
