ansible/CHANGELOG.md

Ansible Changes By Release

1.2 "Right Now" -- release pending

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.

0.6 "Cabo" -- August 6, 2012

playbooks:

• support to tag tasks and includes and use --tags in playbook CLI
• playbooks can now include other playbooks (example/playbooks/nested_playbooks.yml)
• vars_files now usable with with_items, provided file paths don't contain host specific facts
• error reporting if with_items value is unbound

• to catch typos, like 'var' for 'vars', playbooks and tasks now yell on invalid parameters
• automatically load (directory_of_inventory_file)/group_vars/groupname and /host_vars/hostname in vars_files
• playbook is now colorized, set ANSIBLE_NOCOLOR=1 if you do not like this, does not colorize if not a TTY
• hostvars now preserved between plays (regression in 0.5 from 0.4), useful for sharing vars in multinode configs
• ignore_errors: yes on a task can be used to allow a task to fail and not stop the play
• with_items with the apt/yum module will install/remove/update everything in a single command

inventory:

• groups variable available as a hash to return the hosts in each group name
• in YAML inventory, hosts can list their groups in inverted order now also (see tests/yaml_hosts)
• YAML inventory is deprecated and will be removed in 0.7
• ec2 inventory script
• support ranges of hosts in the host file, like www[001-100].example.com (supports leading zeros and also not)

modules:

• fetch module now does not fail a system when requesting file paths (ex: logs) that don't exist
• apt module now takes an optional install-recommends=yes|no (default yes)
• fixes to the return codes of the copy module

• setup module no longer saves to disk, template module now only used in playbooks
• setup module no longer needs to run twice per playbook
• apt module now passes DEBIAN_FRONTEND=noninteractive
• mount module (manages active mounts + fstab)
• setup module fixes if no ipv6 support

• git module fixes
• setup module overhaul, more modular
• minor caching logic added to inventory to reduce hammering of inventory scripts.
• MySQL and PostgreSQL modules for user and db management
• vars_prompt now supports private password entry (see examples/playbooks/prompts.yml)

internals:

• when sudoing to root, still use /etc/ansible/setup as the metadata path, as if root
• paramiko is now only imported if needed when running from source checkout
• cowsay support on Ubuntu
• various ssh connection fixes for old Ubuntu clients
• ./hacking/test-module now supports options like ansible takes and has a debugger mode

0.4 "Unchained" ------- May 23, 2012

Internals/Core

• internal inventory API now more object oriented, parsers decoupled
• async handling improvements
• misc fixes for running ansible on OS X (overlord only)
• sudo improvements, now works much more smoothly
• sudo to a particular user with -U/--sudo-user, or using 'sudo_user: foo' in a playbook
• --private-key CLI option to work with pem files

Inventory

• can use -i host1,host2,host3:port to specify hosts not in inventory (replaces --override-hosts)
• ansible INI style format can do groups of groups [groupname:children] and group vars [groupname:vars]
• groups and users module takes an optional system=yes|no on creation (default no)
• list of hosts in playbooks can be expressed as a YAML list in addition to ; delimited

Playbooks

• variables can be replaced like ${foo.nested_hash_key.nested_subkey[array_index]}
• unicode now ok in templates (assumes utf8)
• able to pass host specifier or group name in to "hosts:" with --extra-vars
• ansible-pull script and example playbook (extreme scaling, remediation)
• inventory_hostname variable available that contains the value of the host as ansible knows it
• variables in the 'all' section can be used to define other variables based on those values
• 'group_names' is now a variable made available to templates
• first_available_file feature, see selective_file_sources.yml in examples/playbooks for info
• --extra-vars="a=2 b=3" etc, now available to inject parameters into playbooks from CLI

Incompatible Changes

• jinja2 is only usable in templates, not playbooks, use $foo instead
• --override-hosts removed, can use -i with comma notation (-i "ahost,bhost")
• modules can no longer include stderr output (paramiko limitation from sudo)

Module Changes

• tweaks to SELinux implementation for file module
• fixes for yum module corner cases on EL5
• file module now correctly returns the mode in octal
