Use case: e.g. dual homed hosts on production en management network
The inventory_hostname is the regular host name and matches the
dns name on the production network; ansible connects to the host
through a management network; the dns name on the management network
is standardized and equals ${inventory_hostname}-mgt.mynetwork.com
Now this can be configured as the default in group_vars/all:
ansible_ssh_host: {{ inventory_hostname + '-mgt.mynetwork.com' }}
str() throws an UnicodeEncodeError for code points that cannot be
represented in 7-bit ASCII. This makes it impossible to use any
non-ASCII characters in module arguments. Using encode('utf-8')
gives the desired result.
* Moved the --list-hosts option that is common to both `ansible` and
`ansible-playbook` into utils/__init__.py (corrects a FIXME)
* Wrote new help text for the --list-hosts option that makes sense
for both of the commands that it applies to
* Changed the usage argument in `ansible-playbook` so that it is
setup in the base_parser method the same way that it is in
the `ansible` executable
* Updated the help text for several options to correct typos,
clarify meaning, improve readability, or fix grammatical errors.
In the case of `ansible-pull`, I changed the help text so that
it adheres to the same standards as the other executables.
The action doesn't actually change anything on a system, so setting
the status to changed is wrong. add_host is much like set_fact in that
regard.
Since changed is False by default, there is no need to explicity set
it, so just create an empty dict for result and add to it from there.
ansible.constants was calling expanduser (by way of shell_expand_path)
on the entire configured value for the library and *_plugins
configuration values, but these values have always been interpreted as
multiple directories separated by os.pathsep. Thus, if you supplied
multiple directories for one of these values, typically only the first
(at least on *nix) would have e.g. "~" expanded to HOME.
Now PluginLoader does expansion on each individual path in each of
these variables.
A host pattern of the form '!foo' by itself does not work, but
'all:!foo' does. If the first pattern is a negation, this commit
automatically prepends 'all'.

name is used throughout Ansible, it's the "standard". This change
applies that standard to the add_host routine and updates the docs to
reflect that. Related to https://github.com/ansible/ansible/pull/3254

Optionally fail task on undefined variables
This patch introduces a new configuration option called
error_on_undefined_vars, which defaults to false.
If this option is set to true, then a task which has unevaluated
variables in its arguments will fail instead of running. Output looks
like this:
TASK: [set rabbitmq password] *************************************************
fatal: [10.20.0.7] => Undefined variables: rabbitmq_user, rabbitmq_password

Previous commit c3659741 expanded sudo_user during task construction,
but this is too early as it does not pick up variables set during
the play.
This commit moves sudo_user expansion to the runner after variables
have been merged.
e.g. db[01:10:3]node-[01:10]
- to do this we split off at the first [...] set, getting the list
of hosts and then repeat until none left.
- also add an optional third parameter which contains the step. (Default: 1)
so range can be [01:10:2] -> 01 03 05 07 09
If someone has a " #" in a quoted var string, it
will interpret that as a comment and refuse to
load the inventory file due to an unbalanced
quote. Noisy failure > unexpected behavior.
Previously setting force=no caused copy to subversively
fail when target did not exist on remote host.
Caused by Runner._remote_md5 returning 1
when files don't exist, rather than 0.
PluginLoader._get_paths, as of 391fb98e, was only finding plug-ins that
were in a subdirectory of one of the basedirs (i.e. in a category
directory). For example, action_plugins/foo.py would never be loaded,
but action_plugins/bar/foo.py would work.
This makes it so that "uncategorized" plug-ins in the top level of a
directory such as action_plugins will be loaded, though plug-ins in a
"category" subdirectory will still be preferred. For example,
action_plugins/bar/foo.py would be preferred over action_plugins/foo.py.
If a variable was provided for an include, in either of these ways:
---
- hosts: all
tasks:
- include: included.yml param=www-data
- include: included.yml
vars:
param: www-data
and then that param was used as the value of sudo_user in the included
tasks:
---
- name: do something as a parameterized sudo_user
command: whoami
sudo: yes
sudo_user: $param
you would receive a "failed to parse: usage: sudo" error back and the
command would not execute.
This seemed to be due to a missing call to template.template somewhere,
because the final value being passed through ssh was still `$param`.
After some digging, the issue seems to instead have been a problem with
providing the wrong context to the template for expansion. Inside the
`Task` logic, it was passing `play.vars` as the context, where
`module_vars` seemed more appropriate. After replacing it, my test case
above ran without issue. There was a comment above suggesting that the
template call might be unnecessary, but removing it made the original
error return, since it is not getting escaped later down the line. I
removed the comment since it was inaccurate.
I tried to actually incorporate my test case above into the test suite
as a regression test, but was unable to figure out how to structure it.
The existing test infrastructure seemed to only be testing for correct
number of counts in things (ok vs. changed, etc.), without regard for
whether the content generated by the command is correct. If there is an
example of a test similar to this one (where I would want to check the
JSON generated to make sure sudo_user had been converted), please let me
know and I will be happy to submit an additional patch.
Excplicity set paramiko's logging level to WARNING.
By default it inherits ansible's DEBUG logging level (set in
callbacks.py) and fills the log file with useless debug messages.
Obviously it only applies if log_path is set in ansible.cfg
Added new parameter 'encrypt' with same semantics from that of
vars_prompt. When encryption is requested a random salt will be
generated and stored along the password in the form:
'<password> salt=<salt>'.
Also store passwords with an ending '\n' for easier looking at files
with console tools. File content was being already rstripped so this
is harmless.
From issue #2820, --start-at-task does not actually run tasks
unless --step is specified. This appears to be because skip_task
is being evaluated as True in PlayBook._run_task(). This patch
ensures skip_task is set to False in the callback.
This is intended to fix#2810. It sets the context of the tmp_dest file
after shutil.move() operation and before os.rename(). This should
retain the selinux context of the file across moves.
There are various cases where a UID to username to UID mapping breaks
down. One UID can be used by two usernames, or no username. If we
always use UIDs internally, then these ambiguous cases won't be a
problem.
The old test used syntax that appeared to be bash-specific and did not
work on platforms where /bin/sh did not point to bash. See issue #2742
where copy to solaris hosts failed with the error:
output: {'stdout': '', 'stderr': '/bin/sh: test: argument expected\n',
'rc': 1}
This fixes#2632. Briefly: specifying things like paths using complex
args in a playbook will make the objects unicode instances. The selinux
module does not accept unicode instances for its char * arguments; it
wants str instances.
Per mpdehaan's comment on #2632 I just went ahead and converted all
paths to UTF-8. I don't know if it would be better to do something like
converting to locale.getpreferredencoding(), but I factored all the
conversions out into new method _to_filesystem_str, so there's only one
place that needs to be changed in the future.
This module allows you to set host facts (or export play variables to the playbook scope if you fancy that).
The module also accepts complex arguments.
```yaml
- action: set_fact fact="something" global_fact="${local_var}"'
- action: set_fact
args:
fact: something
global_fact: ${local_var}
```
- add a skip option so it won't raise an exception if you don't match anything
- make it work as a drop-in replacement for first_available_file
- document in the module comments all of the above cases
AR function was leaving some tmp files behind, want to revert, will have better implementation soon, this is the old way now.
This reverts commit f74a1fa4f0.
Lookup plugins 'sequence' and 'template' now import 'ansible.utils'
appropriately in order to use the 'listify_lookup_plugin_terms'
function.
Also, 'dnstxt' and 'env' now check to see if 'terms' is a string;
without this calls like '{{ lookup('env', 'HOME') }}' fail.
The copy action accepts force=no, which tells it not to replace an
existing file even if it differs from the source. The copy action
plug-in wasn't respecting this option when operated in check mode, so it
would report that changes are necessary in check mode even though copy
would make no changes when run normally.
Runner._remote_md5 was changed to make the logic for setting rc perhaps
a little more clear, and to make sure that rc=0 when the file does not
exist.
Look for a file with the base name of the group/host, first without
a file extension, then with a '.yml' extension, and, finally, with
a '.yaml' extension, loading vars from only the first one found.
As documented in #2623, early variable substitution causes when_
tests to fail and possibly other side effects.
I can see the reason for this early substitution, likely introduced
in 1dfe60a6, to allow many playbook parameters to be templated.
This is a valid goal, but the recursive nature of the utils.template
function means that it goes too far.
At this point removing tasks from the list of parameters to be
substituted seems sufficient to make my tests pass. It may be the
case that other parameters should be excluded, but I suspect not.
Adding a test case. I would prefer to analyse not just the aggregate
statistics but also whether the results are as expected - I can't
see an easy way to do that with the available callbacks at present.
Technically this isn't quite valid YAML when this happens, so we make it valid. This means that if a future commander
API allows save/load it should make sure it does similar processing.
evaluate and replace '$item' with ''. Really it doesn't make sense to include multiple playbooks
via a loop variable, as you can do this with task + with_items already (and it's a simpler code
path). Given this is undocumented, this removes that feature, and we'll consider next how to
also add 'with_items' support directly to roles.
When operating on a unicode string in python 2.6, shlex.split returns
a result that does not work with the file constructor.
To reproduce this requires a task include that is templated (this is
because the templated string is a unicode result, whereas a non-
templated string is a non-unicode string)

The proposed fix (coercing the include parameters to string before the
