* play, block, task: New attribute forks With this it is possible to limit the number of concurrent task runs. forks can now be used in play, block and task. If forks is set in different levels in the chain, then the smallest value will be used for the task. The attribute has been added to the Base class as a list to easily provide all the values that have been set in the different levels of the chain. A warning has been added because of the conflict with run_once. forks will be ignored in this case. The forks limitation in StrategyBase._queue_task is not used for the free strategy. Signed-off-by: Thomas Woerner <twoerner@redhat.com> * Handle forks in free strategy The forks attribute for the free strategy is handled in run in the free StrategyModule. This is dony by counting the amount of tasks where the uuid is the same as the current task, that should be queued next. If this amount is bigger or equal to the forks attribute from the chain (task, block, play), then it will be skipped to the next host. Like it is also done with blocked_hosts. Signed-off-by: Thomas Woerner <twoerner@redhat.com> * Test cases for forks with linear and free strategy With ansible_python_interpreter defined in inventory file using ansible_playbook_python. Signed-off-by: Thomas Woerner <twoerner@redhat.com> * Changing forks keyword to throttle and adding some more docs |

Ansible
Ansible is a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy. More information on the Ansible website.
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.
Use Ansible
You can install a released version of Ansible via pip, a
package manager, or our release repository. See
our installation
guide for details on installing Ansible on a variety of
platforms.
Red Hat offers supported builds of Ansible Engine.
Power users and developers can run the devel branch,
which has the latest features and fixes, directly. Although it is
reasonably stable, you are more likely to encounter breaking changes
when running the devel branch. We recommend getting
involved in the Ansible community if you want to run the
devel branch.
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.
- Join a Working Group, an organized community devoted to a specific technology domain or platform.
- Submit a proposed code update through a pull request to the
develbranch. - Talk to us before making larger changes to avoid duplicate efforts. This not only helps everyone know what is going on, it also helps save time and effort if we decide some changes are needed.
- For a list of email lists, IRC channels and Working Groups, see the Communication page
Branch Info
- The
develbranch corresponds to the release actively under development. - The
stable-2.Xbranches correspond to stable releases. - Create a branch based on
develand set up a dev environment if you want to open a PR. - See the Ansible release and maintenance page for information about active branches.
Roadmap
Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.7, 2.8). The Ansible Roadmap page details what is planned and how to influence the roadmap.
