Included Scripts¶

bootstrap-ansible.sh¶

The bootstrap-ansible.sh script installs Ansible including 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+https://github.com/ansible/ansible@devel#egg=ansible"

• 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.

bootstrap-aio.sh¶

The bootstrap-aio.sh 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.

run-playbooks.sh¶

The run-playbooks script is designed to be executed in development and test environments and is also used for automated testing. It executes actions which are definitely not suitable for production environments and must therefore not be used for that purpose.

The default MaxSessions setting for the OpenSSH Daemon is 10. Each Ansible fork makes use of a Session. By default Ansible sets the number of forks to 5, but the run-playbooks.sh script sets the number of forks used based on the number of CPU’s on the deployment host up to a maximum of 10.

If a developer wishes to increase the number of forks used when using this script, override the ANSIBLE_FORKS environment variable. For example:

export ANSIBLE_FORKS=20

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
