* Restart EC2 instances with multiple network interfaces A previous bug, #3234, caused instances with multiple ENI's to fail when being started or stopped because sourceDestCheck is a per-interface attribute, but we use the boto global access to it (which only works when there's a single ENI). This patch handles a variant of that bug that only surfaced when restarting an instance, and catches the same type of exception. * Default termination_protection to None instead of False AWS defaults the value of termination_protection to False, so we don't need to explicitly send `False` when the user hasn't specified a termination protection level. Before this patch, the below pair of tasks would: 1. Create an instance (enabling termination_protection) 2. Restart that instance (disabling termination_protection) Now, the default None value would prevent the restart task from disabling termination_protection. ``` - name: make an EC2 instance ec2: vpc_subnet_id: {{ subnet }} instance_type: t2.micro termination_protection: yes exact_count: 1 count_tag: Name: TestInstance instance_tags: Name: TestInstance group_id: {{ group }} image: ami-7172b611 wait: yes - name: restart a protected EC2 instance ec2: vpc_subnet_id: {{ subnet }} state: restarted instance_tags: Name: TestInstance group_id: {{ group }} image: ami-7172b611 wait: yes ``` |

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/
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 rebasevsgit mergefor 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 Led Zeppelin songs. (Releases prior to 2.0 were 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.
