Ansible Changes By Release

1.2.1 "Hear About It Later" (reprise) -- July 4, 2013

  • Added a configuration file option [paramiko_connection] record_host_keys which allows the code that paramiko uses to update known_hosts to be disabled. This is done because paramiko can be very slow at doing this if you have a large number of hosts and some folks may not want this behavior. This can be toggled independently of host key checking and does not affect the ssh transport plugin. Use of the ssh transport plugin is preferred if you have ControlPersist capability, and Ansible by default in 1.2.1 and later will autodetect.

1.2.1 "Hear About It Later" -- July 4, 2013

  • Connection default is now "smart", which discovers if the system openssh can support ControlPersist, and uses it if so, if not falls back to paramiko.
  • Host key checking is on by default. Disable it if you like by adding host_key_checking=False in the [default] section of /etc/ansible/ansible.cfg or ~/ansible.cfg or by exporting ANSIBLE_HOST_KEY_CHECKING=False
  • Paramiko now records host keys it was in contact with host key checking is on. It is somewhat sluggish when doing this, so switch to the 'ssh' transport if this concerns you.

1.2 "Right Now" -- June 10, 2013

Core Features:

  • capability to set 'all_errors_fatal: True' in a playbook to force any error to stop execution versus a whole group or serial block needing to fail usable, without breaking the ability to override in ansible
  • ability to use variables from {{ }} syntax in mainline playbooks, new 'when' conditional, as detailed in documentation. Can disable old style replacements in ansible.cfg if so desired, but are still active by default.
  • can set ansible_private_key_file as an inventory variable (similar to ansible_ssh_host, etc)
  • 'when' statement can be affixed to task includes to auto-affix the conditional to each task therein
  • cosmetic: "*****" banners in ansible-playbook output are now constant width
  • --limit can now be given a filename (--limit @filename) to constrain a run to a host list on disk
  • failed playbook runs will create a retry file in /var/tmp/ansible usable with --limit
  • roles allow easy arrangement of reusable tasks/handlers/files/templates
  • pre_tasks and post_tasks allow for separating tasks into blocks where handlers will fire around them automatically
  • "meta: flush_handler" task capability added for when you really need to force handlers to run
  • new --start-at-task option to ansible playbook allows starting at a specific task name in a long playbook
  • added a log file for ansible/ansible-playbook, set 'log_path' in the configuration file or ANSIBLE_LOG_PATH in environment
  • debug mode always outputs debug in playbooks, without needing to specify -v
  • external inventory script added for Spacewalk / Red Hat Satellite servers
  • It is now possible to feed JSON structures to --extra-vars. Pass in a JSON dictionary/hash to feed in complex data.
  • group_vars/ and host_vars/ directories can now be kept alongside the playbook as well as inventory (or both!)
  • more filters: ability to say {{ foo|success }} and {{ foo|failed }} and when: foo|success and when: foo|failed
  • more filters: {{ path|basename }} and {{ path|dirname }}
  • lookup plugins now use the basedir of the file they have included from, avoiding needs of ../../../ in places and increasing the ease at which things can be reorganized.

  • merged ansible-plugins, ansible-resources, and ansible-docs into the main project
  • you can set ANSIBLE_NOCOWS=1 if you want to disable cowsay if it is installed. Though no one should ever want to do this! Cows are great!

  • fatal errors are now properly colored red.
  • skipped messages are now cyan, to differentiate them from unchanged messages.
  • extensive documentation upgrades
  • delegate_action to localhost (aka local_action) will always use the local connection type

Other playbook changes:

  • to_yaml and from_yaml are available as Jinja2 filters
  • $group and $group_names are now accessible in with_items
  • where 'stdout' is provided a new 'stdout_lines' variable (type == list) is now generated and usable with with_items
  • when local_action is used the transport is automatically overridden to the local type
  • output on failed playbook commands is now nicely split for stderr/stdout and syntax errors
  • if local_action is not used and delegate_to was 127.0.0.1 or localhost, use local connection regardless

  • fix for multi_line strings with only_if

New Modules:

  • postgresql modules now take an optional port= parameter
  • /proc/cmdline info is now available in Linux facts
  • public host key detection for OS X

  • additional facts for SunOS virtualization
  • copy module is now atomic when used across volumes
  • url_get module now returns 'dest' with the location of the file saved
  • fix for yum module when using local RPMs vs downloading
