This extends ansible-pull so that it can support using other
source_control modules for checking out a playbook repository
(issue #3372). This will check to see if the module exists before
it attempts to do the checkout and will exit if the module is not found.
It requires that the module used to check out the repository support the
parameters 'name' and 'version'. The option -C, --checkout is now
optional and defaults to the module's default behavior for selecting a
branch, tag, or commit value. For git, this continues to be HEAD.
Other changes include:
* Remove git from help and use generic term(s) where needed.
* Use SortedOptParser from ansible.utils
* More abstraction of common options used between ansible and
ansible-playbook.
Provide hints to playbook callers that a playbook execution had
unreachable vs failures. 2 == failures, 3 == no failures, but
unreachable hosts. 0 continues to be all good.
With the command line option "-c local", ansible and ansible-playbook
should never ask for a SSH password even if this is set in the config.
Fixes#3720
* 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.
Add option to specify inventory. No default is defined since
ansible-playbook already does this and it allows an ansible.cfg in the
git repository to take precedence.
Overall, this should help ansible-pull work with less setup in advance,
which should be helpful in kickstart scenarios. Much of this was
discussed in issue #2464.
A recent change to ansible-playbook to support json extra-vars
also inadvertently broke the script when no extra-vars are
provided. Simply checking to make sure it is defined and truthy
should take care of the issue.
And also be liberal in what ansible-doc accepts as an empty
requirements specification.
While here fix a typo in template module documentation
wrt jinja2 overrides example.
