Like Vagrant's default SSH behaviors (e.g ssh or ssh-config commands),
the Ansible provisioner should by default not modify or read the user
known host file (e.g. ~/.ssh/known_hosts).
Given that `UserKnownHostsFile=/dev/null` SSH option is usually combined
with `StrictHostKeyChecking=no`, it seems quite reasonable to bind the
activation/disactivation of both options to `host_key_checking`
provisioner attribute.
For the records, a discussion held in Ansible-Development mailing list
clearly confirmed that there is no short-term plan to adapt Ansible to
offer an extra option or change the behavior of
ANSIBLE_HOST_KEY_CHECKING. For this reason, the current implementation
seems reasonable and should be stable on the long run.

- force `--connection=ssh` (any other modes like paramiko or smart are not
supported)
- give the highest priority to `raw_arguments` for sake of simplicity (in
usage, in code and in documentation)
- fix position of the `--limit` argument (the generated inventory could be
shadowed by `raw_arguments`, while ansible.limit was able to override
`raw_arguments`
ref #3396
When `--connection` argument is not specified, Ansible will use the
'smart' mode, which can either use `ssh` or `paramiko` transports,
depending of the version of OpenSSH available. If OpenSSH version is new
enough to support ControlPersist technology, `ssh` will be used.
See also http://docs.ansible.com/intro_configuration.html#transport.
In order to support some advanced features of Vagrant (e.g. multiple ssh
private key identities or ssh forwarding), the Ansible provisioner
already must force `ssh` connection mode.
Having to deal with the possible fallback to `paramiko` increase the
burden of special cases that Ansible provisioner must handle, without
any added value, as Vagrant is based on OpenSSH and its users are
usually using modern operating systems.
With this change, the Ansible provisioner will officially only support
`ssh`. It will still be possible to switch to another connection mode
via `raw_arguments`, but it will breach the "contract", and no
(community) support can be expected in such use case.
ref #3900, #3396
I still cannot explain the cause of these random errors in this unit test,
but it is anyway safe and suitable to update the test code as following:
- use stricter regular expression matching (-l is included in --limit)
- array lengths substraction instead of array contents substraction
Motivation:
By printing out the ansible command used behind the scene, we can ease
the support effort to very quickly identify whether a problem is due to
Vagrant provisioner or Ansible itself.
There's very little difference between the command building on Linux and Windows other than path formatting. All Chef provisioners support the --no-color argument now.
Added unit tests to verify changes.
CommandBuilderWindows would not include the Chef binary in the command when the binary_path was specified in the config.
Backfilled unit tests for CommandBuilderWindows
Combine a maximum of options in the last test:
- Ansible Vault options from [GH-3338]
- raw_arguments
Note: it is not expected from Vagrant to reject incoherent combinations
- Don't mock the config object, but use a true instance
- When possible, take advantage of Rpsec before/after hooks to
reduce code repetitions
- Add an example ("with inventory_path option")
- Use a global variable to store the path of the generated inventory
- Miscellaneous changes in existing examples (style, fixes)
Pull up encrypted data bag secret management into the base classes, thus
also unifying the functionality.
Especially this complements the issues:
* Upload the secret to provisioning path also with chef-solo [GH-1246]
* Delete the secret also with chef-client [GH-2712]
* Remove the secret before uploading also with chef-client [GH-1111]
of `args` itself and as an element inside of an `args` array. Added validation
around passing in arrays for arguments. Just knowing that it is an array is not
enough, because arrays can contain any other type.
