This change is similar to https://github.com/ansible/ansible/pull/10465 It extends the logic there to also support none types. Right now if you have a '!!null' in yaml, and that var gets passed around, it will get converted to a string. eg. defaults/main.yml ``` ENABLE_AWESOME_FEATURE: !!null # Yaml Null OTHER_CONFIG: secret1: "so_secret" secret2: "even_more_secret" CONFIG: hostname: "some_hostname" features: awesame_feature: "{{ ENABLE_AWESOME_FEATURE}}" secrets: "{{ OTHER_CONFIG }}" ``` If you output `CONFIG` to json or yaml, the feature flag would get represented in the output as a string instead of as a null, but secrets would get represented as a dictionary. This is a mis-match in behaviour where some "types" are retained and others are not. This change should fix the issue. I also updated the template test to test for this and made the changes to v2. Added a changelog entry specifically for the change from empty string to null as the default. Made the null representation configurable. It still defaults to the python NoneType but can be overriden to be an emptystring by updating the DEFAULT_NULL_REPRESENTATION config. |

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 http://ansible.com/
Many users run straight from the development branch (it's generally fine to do so), but you might also wish to consume a release.
You can find instructions here for a variety of platforms. If you decide to go with the development branch, be sure to run git submodule update --init --recursive
after doing a checkout.
If you want to download a tarball of a release, go to releases.ansible.com, though most users use yum
(using the EPEL instructions linked above), apt
(using the PPA instructions linked above), or pip install ansible
.
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 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
vsgit 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 and 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
- Development list: ansible-devel
- Announcement list: ansible-announce - read only
- irc.freenode.net: #ansible
Branch Info
- Releases are named after Van Halen songs.
- The devel branch corresponds to the release actively under development.
- As of 1.8, modules are kept in different repos, you'll want to follow core and extras
- Various release-X.Y branches exist for previous releases.
- We'd love to have your contributions, read Community Information for notes on how to get started.
