In the process of building up the inventory by parsing each inventory
source with each available inventory plugin, there are three kinds of
possible errors (listed in order from earliest to latest):
1. One source could not be parsed by a particular plugin.
2. One source could not be parsed by any available plugin.
3. ALL sources could not be parsed by any available plugin.
The errors in (1) are a part of normal operation, e.g., the script
plugin is expected to fail to parse an ini-format source, and we will
ignore that error and try the next plugin. There is currently no way to
control this, and no known compelling use-case for a setting to control
it. This commit does not make any changes here.
We implement "any_unparsed_is_failed" to handle (2) above. If enabled,
this requires that every available source be parsed validly by at least
one plugin. In an inventory comprising a static hosts file and ec2.py,
this setting will cause a fatal error if ec2.py fails (a situation that
attracted only a warning earlier).
We clarify that the existing "unparsed_is_failed=true" setting causes a
fatal error only in (3) above, i.e., if NO inventory source could be
parsed. In other words, if there is ANY valid source in the inventory
(e.g., an ini-format static file), no combination of errors and the
setting will cause a fatal error.
If you want to execute your playbooks when your inventory is…
(a) complete, use "any_unparsed_is_failed=true".
(b) not empty, use "unparsed_is_failed=true".
The "unparsed_is_failed" setting should be renamed to
"all_unparsed_is_failed", but this commit does not do so.

|PyPI version| |Docs badge| |Build Status| ******* Ansible ******* Ansible is a radically simple IT automation system. It handles configuration-management, application deployment, cloud provisioning, ad-hoc task-execution, and multinode orchestration -- including trivializing things like zero-downtime rolling updates with load balancers. Read the documentation and more at https://ansible.com/ You can find installation instructions `here <https://docs.ansible.com/intro_getting_started.html>`_ for a variety of platforms. Most users should probably install a released version of Ansible from ``pip``, a package manager or our `release repository <https://releases.ansible.com/ansible/>`_. `Officially supported <https://www.ansible.com/ansible-engine>`_ builds of Ansible are also available. Some power users run directly from the development branch - while significant efforts are made to ensure that ``devel`` is reasonably stable, you're more likely to encounter breaking changes when running Ansible this way. Design Principles ================= * Have a dead simple setup process and a minimal learning curve * Manage machines very quickly and in parallel * Avoid custom-agents and additional open ports, be agentless by leveraging the existing SSH daemon * Describe infrastructure in a language that is both machine and human friendly * Focus on security and easy auditability/review/rewriting of content * Manage new remote machines instantly, without bootstrapping any software * Allow module development in any dynamic language, not just Python * Be usable as non-root * Be the easiest IT automation system to use, ever. Get Involved ============ * Read `Community Information <https://docs.ansible.com/community.html>`_ for all kinds of ways to contribute to and interact with the project, including mailing list information and how to submit bug reports and code to Ansible. * All code submissions are done through pull requests. Take care to make sure no merge commits are in the submission, and use ``git rebase`` vs ``git merge`` for this reason. If submitting a large code change (other than modules), it's probably a good idea to join ansible-devel and talk about what you would like to do or add first to avoid duplicate efforts. This not only helps everyone know what's going on, it also helps save time and effort if we decide some changes are needed. * Users list: `ansible-project <https://groups.google.com/group/ansible-project>`_ * Development list: `ansible-devel <https://groups.google.com/group/ansible-devel>`_ * Announcement list: `ansible-announce <https://groups.google.com/group/ansible-announce>`_ -- read only * irc.freenode.net: #ansible Branch Info =========== * Releases are named after Led Zeppelin songs. (Releases prior to 2.0 were named after Van Halen songs.) * The devel branch corresponds to the release actively under development. * Various release-X.Y branches exist for previous releases. * We'd love to have your contributions, read `Community Information <https://docs.ansible.com/community.html>`_ for notes on how to get started. Roadmap ======= Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.0, 2.1). Subminor versions will generally not have roadmaps published. Ansible 2.1 was the first release which published this and asked for feedback in this manner. Feedback on the roadmap and the new process is quite welcome. The team is aiming for further transparency and better inclusion of both community desires and submissions. These are the team's *best guess* roadmaps based on the Ansible team's experience and are also based on requests and feedback from the community. There are things that may not make it due to time constraints, lack of community maintainers, etc. Each roadmap is published both as an idea of what is upcoming in Ansible, and as a medium for seeking further feedback from the community. There are multiple places for you to submit feedback: - Add to the agenda of an IRC `Core Team Meeting <https://github.com/ansible/community/blob/master/meetings/README.md>`_ (preferred) - Ansible's google-group: ansible-devel - AnsibleFest conferences - IRC Freenode channel: #ansible-devel (this one may have things lost in lots of conversation) For additional details consult the published `Ansible Roadmap <https://docs.ansible.com/ansible/devel/roadmap/>`_. Authors ======= Ansible was created by `Michael DeHaan <https://github.com/mpdehaan>`_ (michael.dehaan/gmail/com) and has contributions from over 1000 users (and growing). Thanks everyone!
