Ansible Changes By Release ========================== 0.8 "Cathedral" -- release pending Highlighted Core Changes: * fireball mode -- ansible can bootstrap a ephemeral 0mq (zeromq) daemon that runs as a given user and expires after X period of time. It is very fast. * playbooks with errors now return 2 on failure. 1 indicates a more fatal syntax error. Similar for /usr/bin/ansible * server side action code (template, etc) are now fully pluggable * ability to write lookup plugins, like the code powering "with_fileglob" (see below) Other Core Changes: * ansible config file can also go in '.ansible.cfg' in cwd in addition to ~/.ansible.cfg and /etc/ansible/ansible.cfg * fix for inventory hosts at API level when hosts spec is a list and not a colon delimited string * ansible-pull example now sets up logrotate for the ansible-pull cron job log * negative host matching (!hosts) fixed for external inventory script usage * internals: os.executable check replaced with utils function so it plays nice on AIX * Debian packaging now includes ansible-pull manpage * magic variable 'ansible_ssh_host' can override the hostname (great for usage with tunnels) * date command usage in build scripts fixed for OS X * don't use SSH agent with paramiko if a password is specified * make output be cleaner on multi-line command/shell errors * /usr/bin/ansible now prints things when tasks are skipped, like when creates= is used with -m command and /usr/bin/ansible * when trying to async a module that is not a 'normal' asyncable module, ansible will now let you know * ability to access inventory variables via 'hostvars' for hosts not yet included in any play, using on demand lookups * 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! * you can set ANSIBLE_FORCECOLOR=1 to force color mode even when running without a TTY * 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 Highlighted playbook changes: * is_set is available for use inside of an only_if expression: is_set('ansible_eth0'). We intend to further upgrade this with a 'when' keyword providing better options to 'only_if' in the next release. Also is_unset('ansible_eth0') * playbooks can import playbooks in other directories and then be able to import tasks relative to them * FILE($path) now allows access of contents of file in a path, very good for use with SSH keys * similarly PIPE($command) will run a local command and return the results of executing this command * if all hosts in a play fail, stop the playbook, rather than letting the console log spool on by * only_if using register variables that are booleans now works in a boolean way like you'd expect * task includes now work with with_items (such as: include: path/to/wordpress.yml user=$item) * when using a $list variable with $var or ${var} syntax it will automatically join with commas * setup is not run more than once when we know it is has already been run in a play that included another play, etc * can set/override sudo and sudo_user on individual tasks in a play, defaults to what is set in the play if not present * ability to use with_fileglob to iterate over local file patterns * templates now use Jinja2's 'trim_blocks=True' to avoid stray newlines, small changes to templates may be required in rare cases. 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 * when running a playbook, and the statement has changed, prints 'changed:' now versus 'ok:' so it is obvious without colored mode * variables now usable within vars_prompt (just not host/group vars) * setup facts are now retained across plays (dictionary just gets updated as needed) * --sudo-user now works with --extra-vars * fix for multi_line strings with only_if New Modules: * ini_file module for manipulating INI files * new LSB facts (release, distro, etc) * pause module -- (pause seconds=10) (pause minutes=1) (pause prompt=foo) -- it's an action plugin * a module for adding entries to the main crontab (though you may still wish to just drop template files into cron.d) * debug module can be used for outputing messages without using 'shell echo' * a fail module is now available for causing errors, you might want to use it with only_if to fail in certain conditions Other module Changes, Upgrades, and Fixes: * removes= exists on command just like creates= * postgresql modules now take an optional port= parameter * /proc/cmdline info is now available in Linux facts * public host key detection for OS X * lineinfile module now uses 'search' not exact 'match' in regexes, making it much more intuitive and not needing regex syntax most of the time * added force=yes|no (default no) option for file module, which allows transition between files to directories and so on * 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 * cleaner error messages with copy if destination directory does not exist * setup module now still works if PATH is not set * service module status now correct for services with 'subsys locked' status * misc fixes/upgrades to the wait_for module * git module now expands any "~" in provided destination paths * ignore stop error code failure for service module with state=restarted, always try to start * inline documentation for modules allows documentation source to built without pull requests to the ansible-docs project, among other things * variable '$ansible_managed' is now great to include at the top of your templates and includes useful information and a warning that it will be replaced * "~" now expanded in command module when using creates/removes * mysql module can do dumps and imports * selinux policy is only required if setting to not disabled * various fixes for yum module when working with packages not in any present repo 0.7 "Panama" -- Sept 6 2012 Module changes: * login_unix_socket option for mysql user and database modules (see PR #781 for doc notes) * new modules -- pip, easy_install, apt_repository, supervisorctl * error handling for setup module when SELinux is in a weird state * misc yum module fixes * better changed=True/False detection in user module on older Linux distros * nicer errors from modules when arguments are not key=value * backup option on copy (backup=yes), as well as template, assemble, and lineinfile * file module will not recurse on directory properties * yum module now workable without having repoquery installed, but doesn't support comparisons or list= if so * setup module now detects interfaces with aliases * better handling of VM guest type detection in setup module * new module boilerplate code to check for mutually required arguments, arguments required together, exclusive args * add pattern= as a paramter to the service module (for init scripts that don't do status, or do poor status) * various fixes to mysql & postresql modules * added a thirsty= option (boolean, default no) to the get_url module to decide to download the file every time or not * added a wait_for module to poll for ports being open * added a nagios module for controlling outage windows and alert statuses * added a seboolean module for getsebool/setsebool type operations * added a selinux module for controlling overall SELinux policy * added a subversion module * added lineinfile for adding and removing lines from basic files * added facts for ARM-based CPUs * support for systemd in the service module * git moduleforce reset behavior is now controllable * file module can now operate on special files (block devices, etc) Core changes: * ansible --version will now give branch/SHA information if running from git * better sudo permissions when encountering different umasks * when using paramiko and SFTP is not accessible, do not traceback, but return a nice human readable msg * use -vvv for extreme debug levels. -v gives more playbook output as before * -vv shows module arguments to all module calls (and maybe some other things later) * don not pass "--" to sudo to work on older EL5 * make remote_md5 internal function work with non-bash shells * allow user to be passed in via --extra-vars (regression) * add --limit option, which can be used to further confine the pattern given in ansible-playbooks * adds ranged patterns like dbservers[0-49] for usage with patterns or --limit * -u and user: defaults to current user, rather than root, override as before * /etc/ansible/ansible.cfg and ~/ansible.cfg now available to set default values and other things * (developers) ANSIBLE_KEEP_REMOTE_FILES=1 can be used in debugging (envrionment variable) * (developers) connection types are now plugins * (developers) callbacks can now be extended via plugins * added FreeBSD ports packaging scripts * check for terminal properties prior to engaging color modes * explicitly disable password auth with -c ssh, as it is not used anyway Playbooks: * YAML syntax errors detected and show where the problem is * if you ctrl+c a playbook it will not traceback (usually) * vars_prompt now has encryption options (see examples/playbooks/prompts.yml) * allow variables in parameterized task include parameters (regression) * add ability to store the result of any command in a register (see examples/playbooks/register_logic.yml) * --list-hosts to show what hosts are included in each play of a playbook * fix a variable ordering issue that could affect vars_files with selective file source lists * adds 'delegate_to' for a task, which can be used to signal outage windows and load balancers on behalf of hosts * adds 'serial' to playbook, allowing you to specify how many hosts can be processing a playbook at one time (default 0=all) * adds 'local_action: ' as an alias to 'delegate_to: 127.0.0.1' 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 * 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/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:

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
