Ansible Changes By Release ========================== 0.6 "Cabo" ------------ pending 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 * with_items no longer creates lots of tasks, creates one task that makes multiple calls * can use host_specific facts inside with_items (see above) * at the top level of a playbook, set 'gather_facts: False' to skip fact gathering * first_available_file and with_items used together will now raise an error * 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: True on a task can be used to allow a task to fail and not stop the play * with_items with the apt module will install/remove/update everything in a single command (yum pending) 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 * copy module takes a remote md5sum to avoid large file transfer * various user and group module fixes (error handling, etc) * apt module now takes an optional force parameter * slightly better psychic service status handling for the service module * fetch module fixes for SSH connection type * modules now consistently all take yes/no for boolean parameters (and DWIM on true/false/1/0/y/n/etc) * 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 * internals: template in common module boilerplate, also causes less SSH operations when used * 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 * sudoing to a user other than root now works more seamlessly (uses /tmp, avoids umask issues) 0.5 "Amsterdam" ------- July 04, 2012 * Service module gets more accurate service states when running with upstart * Jinja2 usage in playbooks (not templates), reinstated, supports %include directive * support for --connection ssh (supports Kerberos, bastion hosts, etc), requires ControlMaster * misc tracebacks replaced with error messages * various API/internals refactoring * vars can be built from other variables * support for exclusion of hosts/groups with "!groupname" * various changes to support md5 tool differences for FreeBSD nodes & OS X clients * "unparseable" command output shows in command output for easier debugging * mktemp is no longer required on remotes (not available on BSD) * support for older versions of python-apt in the apt module * a new "assemble" module, for constructing files from pieces of files (inspired by Puppet "fragments" idiom) * ability to override most default values with ANSIBLE_FOO environment variables * --module-path parameter can support multiple directories seperated with the OS path seperator * with_items can take a variable of type list * ansible_python_interpreter variable available for systems with more than one Python * BIOS and VMware "fact" upgrades * cowsay is used by ansible-playbook if installed to improve output legibility (try installing it) * authorized_key module * SELinux facts now sourced from the python selinux library * removed module debug option -D * added --verbose, which shows output from successful playbook operations * print the output of the raw command inside /usr/bin/ansible as with command/shell * basic setup module support for Solaris * ./library relative to the playbook is always in path so modules can be included in tarballs with playbooks 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 * fix for symlink handling in the file module * service takes an enable=yes|no which works with chkconfig or updates-rc.d as appropriate * service module works better on Ubuntu * git module now does resets and such to work more smoothly on updates * modules all now log to syslog * enabled=yes|no on a service can be used to toggle chkconfig & updates-rc.d states * git module supports branch= * service fixes to better detect status using return codes of the service script * custom facts provided by the setup module mean no dependency on Ruby, facter, or ohai * service now has a state=reloaded * raw module for bootstrapping and talking to routers w/o Python, etc Misc Bugfixes * fixes for variable parsing in only_if lines * misc fixes to key=value parsing * variables with mixed case now legal * fix to internals of hacking/test-module development script 0.3 "Baluchitherium" -- April 23, 2012 * Packaging for Debian, Gentoo, and Arch * Improvements to the apt and yum modules * A virt module * SELinux support for the file module * Ability to use facts from other systems in templates (aka exported resources like support) * Built in Ansible facts so you don't need ohai, facter, or Ruby * tempdir selections that work with noexec mounted /tmp * templates happen locally, not remotely, so no dependency on python-jinja2 for remote computers * advanced inventory format in YAML allows more control over variables per host and per group * variables in playbooks can be structured/nested versus just a flat namespace * manpage upgrades (docs) * various bugfixes * can specify a default --user for playbooks rather than specifying it in the playbook file * able to specify ansible port in ansible host file (see docs) * refactored Inventory API to make it easier to write scripts using Ansible * looping capability for playbooks (with_items) * support for using sudo with a password * module arguments can be unicode * A local connection type, --connection=local, for use with cron or in kickstarts * better module debugging with -D * fetch module for pulling in files from remote hosts * command task supports creates=foo for idempotent semantics, won't run if file foo already exists 0.0.2 and 0.0.1 * Initial stages of project
