Vagrant will verify that the current Ansible version does support the
requested compatibility mode (only applicable if not "auto", of course).
As mentioned in the documentation, there is no sanity checks between
`version` option and `compatibility_mode` option.
With this change, the host-based provisioner is also improved to
execute only once the "ansible" command (and store the gathered
information for multiple usages like version requirement and
compatibility checks). On the other hand, the guest-based provisioner
can still potentially execute "ansible" twice (once in the
AnsibleInstalled cap, and via "gather_ansible_version" function via
Base::set_compatibility_mode).
Before this change, only the ansible_local provisioner supported this
option (for ansible version requirement, and pip installation). Now, the
ansible host-based provisioner can also require a exact ansible version.
Resolve#8914
Note: this has been added as part of #6570 resolution, since the
introduction of the `compatibility_mode` auto-detection made both
provisioners made capable to detect ansible version.
Pending: optimize the code to avoid duplicated executions of "ansible
--version" command.
With this change, it is now possible to get rid of many deprecation
messages successively introduced in Ansible 1.9, and 2.0. More
interesting, the generated inventory will contain the recommended
variable names (e.g. `ansible_host` instead of `ansible_ssh_host`)
when the compatibility mode is set to '2.0'.
Details:
- Add `compatibility_mode` option to control the Ansible parameters
format to be used. The value corresponds to the minimal version
supported. For the moment, possible values are '1.8' (corresponding to
Vagrant's former behaviour) or '2.0'.
Note that a dynamic inventory generated in compatibility mode '2.0'
is not supported by Ansible 1.x. On the other hand, Ansible 2.x so far
supports inventory format generated by the compatibility mode '1.8'.
- Add compatibility mode auto-detection, based on the available Ansible
version. This is the default behaviour in order to bring a maximum of
user friendliness. The drawback of this approach is to let potential
compatibility breaking risks, for `ansible` provisioner setups that
already integrate Ansible 2.x **AND** rely on the existence of
the generated `_ssh` variable names. Thanks to the vagrant warnings
(and its release notes), I argue that it is worth to offer
auto-detection by default, which offers a sweet transition to most
users.
- Add `become`, `become_user` and `ask_become_pass` options and their
backwards compatible aliases. The legacy options are now deprecated.
Note that we intentionally didn't provide a '1.9' compatibility mode,
as it would add extra-complexity for practically no added-value.
To my knowledge, the Ansible 2.x series haven't introduced yet any major
changes or deprecations that would motivate to introduce a higher
version compatibility mode (to be confirmed/verified).
Resolve GH-6570
Still Pending:
- Optimization: Reduce the number of `ansible` command executions.
Currently two exec calls will be performed when the compatibility
mode auto-detection is enabled (i.e. by default). We could make the
provisioner a little bit smarter to only execute `ansible` only once
in any situation (by combining "presence" and "version" checks).
- User-friendliness: Add better validator on `compatibility_mode`
option, and shows a warning or an error instead of the silent
fallback on the auto-detection modus.
- Test coverage: All the added behaviours are not fully covered yet.
The patterns "all" is a special keyword that target all hosts in the
inventory. Therefore it makes sense to accept "all:vars" as a group
variable name. Note that "*:vars" pattern is not valid in an Ansible
inventory.

- The 'ansible-galaxy' + 'ansible-playbook' sequence can now be verified
- The "final true" expectation trick can now be removed
- Fixed some little mistakes in 1a62743 rebase of original e8e248d
With this new option defined, the `ansible-galaxy` and
`ansible-playbook` commands generated by the Ansible provisioners will
be executed with the ANSIBLE_CONFIG environment variable set
accordingly.
Resolve GH-7195
This commit also fix the following open issues:
- Implement the pending RSpec examples about path existence checks
performed by the ansible (remote) provisioner.
- In verbose mode, the ansible remote provisioner now correctly displays
the Ansible Galaxy parameters ("role_file" and "roles_path") with
single quotes (which is safer for potential copy-paste usage).
Additional Notes:
- Test coverage for `ansible_local` provisioner is still not
implemented. See GH-6633.
- Test coverage for galaxy from host is not implemented yet (due to
general issue with mocking both command executions, see
https://github.com/mitchellh/vagrant/pull/6529#r45278451
- Honour `ssh.proxy_command` setting (even when the Docker provider is
used via a proxy host). Silly configurations may lead to silly
behaviors, but let's apply the settings...
- Remove condition on `provider_config.connect_via_ssh`, which is
a provider specific parameter (from vagrant-libvirt provider).
- Add a simple unit test
This commit include the following changes:
- systematically set ANSIBLE_ROLES_PATH environment variable when
galaxy_roles_path is defined.
- slightly refactor to introduce the concept of "provisioning working
directory" (possible usage in the future for resolving GH-7195)
- fix a bug in ansible-galaxy execution by the ansible_local provisioner
if the paths contains blank characters.
Fix#7269
With this change, the presence of Ansible configuration files (like
playbook file, inventory path, galaxy role file, etc.) is no longer
performed by the `config` classes, but by the `provisioner` classes
(at the beginning of the provision command).
This change fixes several issues:
- Resolve#6984 as `provision` method are only executed when remote
(ssh) communication with the guest machine is possible.
- Resolve#6763 in a better way than 4e451c6 initially did.
- Improve the general provisioner speed since the `config` checks are
actually triggered by many vagrant actions (e.g. `destroy`,...), and
can also be triggered multiple times during a vagrant run (e.g. on
callback request made by the machine provider).
Unlike the former `config`-based checks, the provision action won't
collect all the invalid options, but only report the first invalid
option found and abort the execution.
Some unit tests were not implemented yet to save my scarce "open source
contribution time" for other important issues, but they should be done
at last via GH-6633.
With cb80286a4a, the helper function
stringify_ansible_playbook_command was also applied on the
`raw_arguments` content, which is not wanted. Given that users have used
the `raw_arguments` option as a workaround to avoid the bug GH-6726,
this new change ensure that any `--extra-vars` option passed as a raw
argument won't be additonally enquoted by the ansible_local
provisioner.
This change also improves the ansible remote provisioner verbose output,
but has no impact on its behaviour, which was already correct.
Note that this refactoring introduces some code duplications that are not
very elegant (see ansible_playbook_command_for_shell_execution in
host.rb and execute_ansible_playbook_from_host in base.rb). I hope we
can find a better implementation later, but it is good enough for now
since all these parts are covered by corresponding unit tests (the
`ansible_local` stuff being tested via the verbose output of the ansible
remote provisioner).
Before this minor change, the '--limit' and '--start-at-task'
ansible-playbook command line arguments were enclosed into single
quotes. Using double quotes adds a bit more flexibility, especially
about the task name referred by `start_at_task` option.
It also aligns with the handling of the '--extra-vars' parameter
(see cb80286).
Without this change, the JSON string generated from the `extra_vars`
Ruby hash is passed without enclosing quotes and is then not parseable
by the ansible-playbook command when exectuted in a usual shell context.
In this changeset, the ansible (remote) unit test coverage is improved
to cover both usage of `extra_vars` (ansible_local unit tests are still
missing).
Additional Notes:
- Double quotes are favored to single quotes in order to allow usage of
any character for the variable values. For this reason additional
escaping is appended to JSON-inner double quotes and backslashes.
- This problem was not affecting the `ansible` remote provisioner
(which is running the ansible-playbook command via the childprocess
Ruby library). But with this change, the `verbose` output will also
now be correct for a copy-paste reuse.
- After this change, all the "--extra-vars" arguments (also a var
file passed with the @-syntax or anything coming via the
`raw_arguments` option) are "blindly" and systematically enclosed
in double quoted and double-escaped.
This is not optimal and can potentially break with peculiar values
(e.g. a double quote character (") cannot be used in a json value
when using `raw_arguments`). That said, I think that the current
solution is a reasonable trade-off, since the official `extra_vars`
option should now be able to cover a great majority of use cases.
Fix#6726
In cd93721, I relied on a suprising combination of quotes to protect ssh
execution to strip the quoted path to the private key file.
Since any ssh command line argument can be passed via
`ANSIBLE_SSH_ARGS`, it is quite more readable and easy to rely on the
`-i` argument, which is not affected like `-o IdentityFile=...` and also
supports multiple occurences.

Finally fix#6671
Note that I decided to not squash both commits for better
documentation and traceability.
Surprisingly (to me at least), a simple quote enclosure was not enough
to fix the problem.
Caveat: the stringified ansible-playbook command logged in verbose mode
is wrongly formatted (no quotes are escaped).
Fix#6671
With the introduction of inventory variables, group members provided as
String are not splitted (by ' ') into an array (instead of
auto-conversion to a single-item array).
String and Symbol types are different when used as a Hash key. By
default the Vagrant machine names are set in Symbol format, but users
may write their `host_vars` entries with String keys. This is a very
simple way to ensure smooth experience, without having to coerce the
data types during the config validation (e.g. with a library like
Hashie, which is currently not in the Vagrant dependencies)

At the moment, the vagrant ssh username is used as default username when
force_remote_user option is disabled, even for winrm-communiating
machines. This could be improved in the future, but people hitting this
problem can easily work around it by syncing `config.ssh.unsername` and
`config.winrm.username` in their Vagrantfile.
ref #5086
With this change, the existing host-based Ansible provisioner is
refactored to share a maximum of code with this new guest-based Ansible
provisioner.
At this stage of development, the existing unit tests are intentionally
modified as little as possible, to keep safe the existing funtionalities.
Other issues resolved by this changeset:
- Display a warning when running from a Windows host [GH-5292]
- Do not run `ansible-playbook` in verbose mode when the `verbose` option
is set to an empty string.
The benefits of the following "breaking change" are the following:
- default behaviour naturally fits with most common usage (i.e. always
connect with Vagrant SSH settings)
- the autogenerated inventory is more consistent by providing both the
SSH username and private key.
- no longer needed to explain how to override Ansible `remote_user` parameters
Important: With the `force_remote_user` option, people still can fall
back to the former behavior (prior to Vagrant 1.8.0), which means that
Vagrant integration capabilities are still quite open and flexible.
When provisioning multiple machines in sequence (the default vagrant
behaviour), it doesn't make sense to require to provide the private ssh
key(s) via the custom ansible inventory script/file.
To align with the handling of multiple ssh keys per machine, we won't
rely any longer on `--private-key` command line argument, but only pass
the keys via `ANSIBLE_SSH_ARGS` environment variable.
Note that when vagrant generates the ansible inventory and that only one
key is associated to a VM, this step would be redundant, and therefore
won't be applied.
This change fixes the breaking change introduced by 3d62a91.
