commit 9921bb9d2002e136c030ff337c14f8b7eab0fc72 Author: Abhijit Menon-Sen <ams@2ndQuadrant.com> Date: Mon Aug 10 20:19:44 2015 +0530 Document --ssh-extra-args command-line option commit 8b25595e7b1cc3658803d0821fbf498c18ee608a Author: Abhijit Menon-Sen <ams@2ndQuadrant.com> Date: Thu Aug 13 13:24:57 2015 +0530 Don't disable GSSAPI/Pubkey authentication when using --ask-pass This commit is based on a bug report and PR by kolbyjack (#6846) which was subsequently closed and rebased as #11690. The original problem was: «The password on the delegated host is different from the one I provided on the command line, so it had to use the pubkey, and the main host doesn't have a pubkey on it yet, so it had to use the password.» (This commit is revised and included here because #11690 would conflict with the changes in #11908 otherwise.) Closes #11690 commit 119d0323892c65e8169ae57e42bbe8e3517551a3 Author: Abhijit Menon-Sen <ams@2ndQuadrant.com> Date: Thu Aug 13 11:16:42 2015 +0530 Be more explicit about why SSH arguments are added This adds vvvvv log messages that spell out in detail where each SSH command-line argument is obtained from. Unfortunately, we can't be sure if, say, self._play_context.remote_user is obtained from ANSIBLE_REMOTE_USER in the environment, remote_user in ansible.cfg, -u on the command line, or an ansible_ssh_user setting in the inventory or on a task or play. In some cases, e.g. timeout, we can't even be sure if it was set by the user or just a default. Nevertheless, on the theory that at five v's you can use all the hints available, I've mentioned the possible sources in the log messages. Note that this caveat applies only to the arguments that ssh.py adds by itself. In the case of ssh_args and ssh_extra_args, we know where they are from, and say so, though we can't say WHERE in the inventory they may be set (e.g. in host_vars or group_vars etc.). commit b605c285baf505f75f0b7d73cb76b00d4723d02e Author: Abhijit Menon-Sen <ams@2ndQuadrant.com> Date: Tue Aug 11 15:19:43 2015 +0530 Add a FAQ entry about ansible_ssh_extra_args commit 49f8edd035cd28dd1cf8945f44ec3d55212910bd Author: Abhijit Menon-Sen <ams@2ndQuadrant.com> Date: Mon Aug 10 20:48:50 2015 +0530 Allow ansible_ssh_args to be set as an inventory variable Before this change, ssh_args could be set only in the [ssh_connection] section of ansible.cfg, and was applied to all hosts. Now it's possible to set ansible_ssh_args as an inventory variable (directly, or through group_vars or host_vars) to selectively override the global setting. Note that the default ControlPath settings are applied only if ssh_args is not set, and this is true of ansible_ssh_args as well. So if you want to override ssh_args but continue to set ControlPath, you'll need to repeat the appropriate options when setting ansible_ssh_args. (If you only need to add options to the default ssh_args, you may be able to use the ansible_ssh_extra_args inventory variable instead.) commit 37c1a5b6794cee29a7809ad056a86365a2c0f886 Author: Abhijit Menon-Sen <ams@2ndQuadrant.com> Date: Mon Aug 10 19:42:30 2015 +0530 Allow overriding ansible_ssh_extra_args on the command-line This patch makes it possible to do: ansible somehost -m setup \ --ssh-extra-args '-o ProxyCommand="ssh -W %h:%p -q user@bouncer.example.com"' This overrides the inventory setting, if any, of ansible_ssh_extra_args. Based on a patch originally by @Richard2ndQuadrant. commit b023ace8a8a7ce6800e29129a27ebe8bf6bd38e0 Author: Abhijit Menon-Sen <ams@2ndQuadrant.com> Date: Mon Aug 10 19:06:19 2015 +0530 Add an ansible_ssh_extra_args inventory variable This can be used to configure a per-host or per-group ProxyCommand to connect to hosts through a jumphost, e.g.: inventory: [gatewayed] foo ansible_ssh_host=192.0.2.1 group_vars/gatewayed.yml: ansible_ssh_extra_args: '-o ProxyCommand="ssh -W %h:%p -q bounceuser@gateway.example.com"' Note that this variable is used in addition to any ssh_args configured in the [ssh_connection] section of ansible.cfg (so you don't need to repeat the ControlPath settings in ansible_ssh_extra_args). |

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.
