Ansible 2.0 has depricated the “ssh” from ansible_ssh_user,
ansible_ssh_host, and ansible_ssh_port to become ansible_user,
ansible_host, and ansible_port. If you are using a version of
Ansible prior to 2.0, you should continue using the older style
variables (ansible_ssh_*). These shorter variables are ignored,
without warning, in older versions of Ansible.
added a note like the following to each file hit with unlabled 2.0 changes...
Ansible 2.0 moved away from using ansible_ssh_* variables to accepting
ansible_* variables. If you are using a version of Ansible prior to 2.0,
you should continue using the older style variables (ansible_ssh_*), such
as ansible_ssh_user instead of ansible_user and ansible_ssh_port instead of
ansible_port, which appear in the following content. These shorter variables
are ignored, without warning, in older versions of Ansible.
Now we have the following ways to set additional arguments:
1. [ssh_connection]ssh_args in ansible.cfg: global setting, prepended to
every command line for ssh/scp/sftp. Overrides default ControlPersist
settings.
2. ansible_ssh_common_args inventory variable. Appended to every command
line for ssh/scp/sftp. Used in addition to ssh_args, if set above, or
the default settings.
3. ansible_{sftp,scp,ssh}_extra_args inventory variables. Appended to
every command line for the relevant binary only. Used in addition to
#1 and #2, if set above, or the default settings.
3. Using the --ssh-common-args or --{sftp,scp,ssh}-extra-args command
line options (which are overriden by #2 and #3 above).
This preserves backwards compatibility (for ssh_args in ansible.cfg),
but also permits global settings (e.g. ProxyCommand via _common_args) or
ssh-specific options (e.g. -R via ssh_extra_args).
Fixes#12576
This allows the EC2 inventory plugin to be used with
the same configuration against different EC2 accounts
Profile can be passed using --profile variable or using
EC2_PROFILE environment variable e.g.
```
EC2_PROFILE=prod ansible-playbook -i ec2.py playbook.yml
```
Added documentation on profiles to EC2 dynamic inventory doc
Only tries to use profiles if --profile argument is given
or EC2_PROFILE is set to maintain compatibility will boto < 2.24.
Works around a minor bug in boto where if you try and use
a security token with a profile it fails (boto/boto#2100)
made new sections for vars, started explaining scope, gave example on command line override of connection vars
added some formatting changes and clarifications
