* add support to vmware_guest for template => vm conversion
While the vmware_guest currently supports conversion of VMs to templates
using the is_template argument, it does not support the inverse:
converting templates back into VMs. This change adds that
functionality.
When converting a template back into a VM, the extra config option
"uuid.action" is also set so that VMware will automatically create a new
UUID for the converted VM. If the "uuid.action" setting is already
configured, it will not be modified. Setting this prevents an
interactive question from being raised when attempting to boot the VM.
* Add integration tests for vmware_guest is_template
* Add additional idempotency test for vmware_guest is_template
* ios_logging: Fix typo in documentation
* ios_logging: Fix traceback when setting buffered destination without size
When the size parameter is not configured while configuring the buffered
destination, a traceback occurs due to the fact that validate_size expects the
parameter to be an int. Explicitely converting value to int makes the
check work for every case.
* ios_logging: Update size parameter documentation
Update the documentation of the size paramter to reflect the current behaviour
of setting a default of 4096 for the buffered dest.
* ios_logging: Add unit test
Add unit test for ios_logging testing the behaviour clarified in the previous
commits.
* ios_logging: Fix python 2.6 compliance
Also add tests for vmware_guest_snapshot, but disable them due to
vcsim not fully supporting such operations yet.
Implement changes suggested in review. Also fix same in remove_or_revert_snapshot() for consistency
* Add check for sv binary
This commit adds a check for the sv binary. If the binary is not present
then the module will fail.
Resolves issue #32248
* Change sv check to suggestion by @bcoca
* Amazon kms_facts module
Facts module for Amazon's Key Management Service
* kms_facts provide aliases
Return aliases for keys
Provide `alias` as a filter
Cope when tags can't be listed
Ensure everything is properly snake cased
* Rename kms_facts to aws_kms_facts
There may be conflicting KMS modules for other providers otherwise.
* Fix documentation, add aliases cache
Aliases are called many times, so add a cache
* Reduce amount of info on deleted keys
Getting info on a key is costly (2s) per key, so reduce
info on deleted keys.
* Add policy information to facts
* aws_kms_facts version update
Fix ridiculously long RETURN line
* Remove dangerous-default-value from aws_kms_facts
This reverts commit 07acc579db.
On closer examination of this code, the conditional that had force in it
was not a parent of this one. So handling of force is needed i both
branches.
See the recent comments on #23391
This module's purpose is to specifically manage the ssl keys. It
is essentially the key component of the bigip_ssl_certificate module.
The modules were separated and the key portion deprecated from
bigip_ssl_certificate in favor of this module.
* Allow cloudformation_facts to exit gracefully if stack does not exist

Only do this if a time limit is not set.
* Consolidate settings
* aws_kms: handle updated policy format+cleanup
- create slightly updated policy in that handles lists instead of a single string; the previous version's policy was being rejected if the key was new enough to have the updated base policy.
- removed `dry_run` conditionals, not committing the policy anyhow.
- return the policy in the return data. Leaving undocumented for now.
- update exception handling: don't rethrow in `do_grant`, don't pass anything to `format_exc`.
* whitespace/indent fail
* fix list-plus-brackets
* str and list fixes for ryansb
* port changes from #31667 over, better listification
* Use latest available template
Documentation states:
template_version: version number of the template to be used for VM. By default the latest available version of the template is used.
This was not true because if parameter was not specified, template[0] is choosen, without checking if is the latest. Now, sorting + selecting the latest selects the one with the latest version number.
* Sort in reverse order, style cleanup
Applied fixes from comment
* make ec2-ami examples less verbose
* Fix default values in docs to be the actual default values
Fix default values for `architecture`, `virtualization_type` and
`wait_timeout` in docs to be the actual default values.
* Added note about examples not containing auth details

This patch changes the base parameters class to segment out the
update method. This is done often throughout the f5 modules, so
this just bakes it into the mod utils so that I can delete it
from each module
The platform/distro/etc facts were being passed in
correctly, but service_mgr.py was looking up the
wrong names ('system' vs 'ansible_system') resulting
in service_mgr falling back to default 'service' result.
Fixes#30753, #31095
We do not go through the effort of finding the right PROTOCOL setting if
we have SSLContext in the stdlib. So we do not want to hit the code
that uses PROTOCOL to set the urllib3-provided ssl context when
SSLContext is available. Also, the urllib3 implementation appears to
have a bug in some recent versions. Preferring the stdlib version will
work around that for those with Python-2.7.9+ as well.

* Handle timezone updates on Ubuntu 16.04+ on containers
Although Ubuntu 16.04 will use timedatectl by default,
containers without a working timedatectl need to use the
old method.
A bug in Ubuntu for the old method means having to write
a nasty hack
https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/1554806
* Add tests for timezones
Ensure timezone changes work across various OSs
* added win_audit_rule with integration test
* Updated integration testing to target files as well as directories
and registry keys. Split testing files apart to be more organized.
Updated powershell for better handling when targetting file objects
and optimized a bit. Removed duplicated sections that got there from a
previous merge I think.
* Decided to make all the fact names the same in integration testing.
Seemed like there would be less change of accidentally using the wrong
variable when copy/pasting that way, and not much upside to having
unique names.
Did final cleanup and fixed a few errors in the integration testing.
* Fixed a bug where results was displaying a wrong value
Fixed a bug where removal was failing if multiple rules existed due to
inheritance from higher level objects.
* Resolved issue with unhandled error when used didn't have permissions
for get-acl.
Changed from setauditrule to addauditrule, see comment in script for reasoning.

This code originated in module_utils/basic.py which was BSD licensed.
In moving it and making it aplicable to other pieces of code that were
using similar functions, I added onto it a little.
Module allows you to wait for a bigip device to be
"ready" for configuration. This module will wait for things like
the device coming online as well as the REST API and MCPD being
ready.
If all of the above is not online and ready, then no configuration
will be able to be made.
* Add nosh service manager module
* based on the `svc`, `systemd`, `runit` and proposed `rc_service`
modules
* uses the high-level 'system-control' command and assumes nosh-native
interfaces though it should work with daemontools-style service scanning
* assumes a single service name is provided
* Metadata fixes
* Added "author" and "version_added"
* fixed the RETURN yaml
* PEP8 fixes
* fixed spacing issue
The current code flow precludes the use of the policy_path module
parameter that's documented. It's actually called policy_file in the
code.
What's worse is that the policy_file branch actually tries to open the
file named by the policy parameter, even though policy and policy_file
are marked as mutually-exclusive.
This change fixes the logic bug in policy_file and updates the
documentation to reference policy_file. The old parameter policy_path
is provided as an alias
* Support 'termination protection' for cloudformation stacks
- Pass in the stack_name and desired termination protection state to update_termination_protection
* Fix for failing cloudformation unit test
* Check if cfn has update_termination_protection attr
* Use hasattr to test if cfn supports update_termination_protection
* termination_protection shouldn't prevent update_stack call for existing stacks
in ServiceNow
Remove "updated" as a option for state, per review from bcoca. Update
examples section, and tested.
Update metadata to 1.1
Rip out some more instances of updated from documentation.
Update for ansible 2.5 first version
* better cleanup on task results display
callbacks get 'clean' copy of result objects
moved cleanup into result object itself
removed now redundant callback cleanup
moved no_log tests
* moved import as per feedback
- added `role_arn` to the "role example" example
- removed the irrelevant parameters to the "role example" example
- updated comment on one of the examples
- removed the last example as it was a duplicate of "role example" example
- some other minor changes
In this refactor we moved to the most recent coding standards for
both F5 and Ansible. Many bugs were fixed and some features were
also added (such as ipv6 support).
New conventions for ansible warrant fixes to accomodate those
in bigip_partition.
This patch also includes an import fix that can raise an error when
Ansible unit tests run
This adds a new type of vault-password script (a 'client') that takes advantage of and enhances the
multiple vault password support.
If a vault password script basename ends with the name '-client', consider it a vault password script client.
A vault password script 'client' just means that the script will take a '--vault-id' command line arg.
The previous vault password script (as invoked by --vault-password-file pointing to an executable) takes
no args and returns the password on stdout. But it doesnt know anything about --vault-id or multiple vault
passwords.
The new 'protocol' of the vault password script takes a cli arg ('--vault-id') so that it can lookup that specific
vault-id and return it's password.
Since existing vault password scripts don't know the new 'protocol', a way to distinguish password scripts
that do understand the protocol was needed. The convention now is to consider password scripts that are
named like 'something-client.py' (and executable) to be vault password client scripts.
The new client scripts get invoked with the '--vault-id' they were requested for. An example:
ansible-playbook --vault-id my_vault_id@contrib/vault/vault-keyring-client.py some_playbook.yml
That will cause the 'contrib/vault/vault-keyring-client.py' script to be invoked as:
contrib/vault/vault-keyring-client.py --vault-id my_vault_id
The previous vault-keyring.py password script was extended to become vault-keyring-client.py. It uses
the python 'keyring' module to request secrets from various backends. The plain 'vault-keyring.py' script
would determine which key id and keyring name to use based on values that had to be set in ansible.cfg.
So it was also limited to one keyring name.
The new vault-keyring-client.py will request the secret for the vault id provided via the '--vault-id' option.
The script can be used without config and can be used for multiple keyring ids (and keyrings).
On success, a vault password client script will print the password to stdout and exit with a return code of 0.
If the 'client' script can't find a secret for the --vault-id, the script will exit with return code of 2 and print an error to stderr.
* documentation was not inline with other Ansible modules
* Python 3 specific imports were missing
* monitor_type is no longer required when creating a new pool; it is now the default.
* A new monitor_type choice of "single" was added for a more intuitive way to specify "a single monitor". It uses "and_list" underneath, but provides additional checks to ensure that you are specifying only a single monitor.
* host and port arguments have been deprecated for now. Please use bigip_pool_member instead.
* 'partition' field was missing from documentation.
* A note that "python 2.7 or greater is required" has been added for those who were not aware that this applies for ALL F5 modules.
* Unit tests were fixed to support the above module
* Correct usage for shutil.rmtree

- add task file name to task names for easier troubleshooting when things fail
* Make archive tests work for RHEL/CentOS 6
The older versions of Jinja2 in RHEL/CentOS 6 required assertion tasks using the map filter to be skipped.
The older version of git required gzip compression to be skipped on RHEL/CentOS 6.
* Account for ansible_distribution_major_version missing
* Adding a cli transport option for the bigip_command module.
* Fixing keyerror when using other f5 modules. Adding version_added for new option in bigip_command.
* Removing local connection check because the F5 tasks can be delegated to any host that has the libraries for REST.
* Using the network_common load_provider.
* Adding unit test to cover cli transport and updating previous unit test to ensure cli was not called.
* new module: AIX rootvg backup image using mksysb
This module is simple but very useful for AIX system
administrators. Easy to construct playbooks to generate
and manage rootvg backups using mksysb tool.
* added module_check, pep8, non-written convention
- implemented module_check;
- fixed some pep8 and non-written convention
* removed parameters as global variables and doc
Moved global variables parameters to inside main()
Better doc format for mentioned files
* wait_for: treat broken connections as "unready"

This appears to happen while the host is still starting; we believe something is
accepting our connection but immediately resetting it. In these cases, we'd
prefer to continue waiting instead of immediately failing the play.
This patch has been applied locally for some time, and we have seen no adverse
effects.

this should allow user to control how they want the playbook dirs inspected
for additional vars, default now reverts to 2.3 behaviour (top).
corrected paths order
minor doc reword
* Properly handle user selection of `None` as vars_files
In a playbook, if a user has a playbook like:
```
- hosts: localhost
connection: local
vars_files:
tasks:
- ....
```
Then `vars_files` will be none, and cause a `TypeError` in vars-manager when it
tries to iterate over them. To avoid this, I changed the getter to either send
back the vars files from the user, or an empty list when the user passed
`None`.
* Only replace None with an empty list, not all falsey values
* Catch error when vars_files isn't iterable
* Move whole `for` loop into try/except and catch TypeError
* Line length
this was abandoned early on the manger side but seems like we left behind on plugin side.
more flexible extensions with yaml plugin
validate data correctly for yaml/constructed
fixed issue with only adding one child to keyed, the group only got the host that forced it's creation

Trying to associate an already-associated ElasticIP was failing.
This is however supported by the `boto` method that is used
under the hood, `associate_address`:
To quote `boto` documentation:
```
This option to allow an Elastic IP address that is already
associated with another networkinterface or instance to be
re-associated with the specified instance or interface.
```
This defaults to False, both per backwards-compatibility
and to mirror the boto default value.
Fixes#27385
* Set desired capacity to min_size if no instances exist
* Improve readability of if/then clause
* Only update null desired_capacity to min_size on initial create
Any future updates to the ASG will be able to reference the existing
capacity.
* Make ansible_selinux facts a consistent type
Rather than returning a bool if the Python library is missing, return a dict with one key containing a message explaining there is no way to tell the status of SELinux on the system becasue the Python library is not present.
* Fix unit test
This reverts commit f8005d2737.
fix needs to be rethought as it applies to only newer git versions
and use of env shell breaks with non 'bourne compatible' shells
* Allow any_errors_fatal to be set in playbook.
* Default to the config file value for any_errors_fatal only if it isn't already provided.

# Remove storage domain
- ovirt_storage_domains:
state: absent
name: mystorage_domain
format: true
Without this PR data_center and host parameters where required when we wanted to
remove some storage domain.
Also fixes a regression when trying to remove a detached
storage domain.
The following patch fixes a regression when trying to remove a detached
storage domain.
As part of the remove process the ovirt_storage_domains module first
tries to move the domain to maintenance and detach it.
In case of removing a detached storage domain with no DC attached to it
The maintenace process will fail with 404 (not exists) exception when
trying to fetch the DC using empty Guid.
The fix proposes a solution to return None value in case of a detached
storage domain.
* Add update_only parameter for yum module
When using latest, `update_only: yes` will ensure that only existing
packages are updated and no additional packages are installed.
* Update yum.py
Update version added for `update_only` parameter to 2.5
* add unit tests for update_only flag in yum module
