# Dynamic inventory script which lets you use aliases from ~/.ssh/config.
|
|
#
|
|
# There were some issues with various Paramiko versions. I took a deeper look
|
|
# and tested heavily. Now, ansible parses this alright with Paramiko versions
|
|
# 1.7.2 to 1.15.2.
|
|
#
|
|
# It prints inventory based on parsed ~/.ssh/config. You can refer to hosts
|
|
# with their alias, rather than with the IP or hostname. It takes advantage
|
|
# of the ansible_ssh_{host,port,user,private_key_file}.
|
|
#
|
|
# If you have in your .ssh/config:
|
|
# Host git
|
|
# HostName git.domain.org
|
|
# User tkarasek
|
|
# IdentityFile /home/tomk/keys/thekey
|
|
#
|
|
# You can do
|
|
# $ ansible git -m ping
|
|
#
|
|
# Example invocation:
|
|
# ssh_config.py --list
|
|
# ssh_config.py --host <alias>
