.bash_aliases_ansible

# Aliases for the ansible docker image
#
# What the command is doing:
# gather arguments to the variable
# starting docker run command
# remove container after command complete
# allocate a pseudo-tty, keep STDIN open even if not attached
# mounting current directory as ansible working directory
# mounting ssh configuration of current user to the container, read only
#
# To use these:
#
#    1) Copy this file to somewhere (e.g. ~/.bash_aliases_ansible).
#    2) Add the following line to your .bashrc/.zshrc:
#        source ~/.bash_aliases_ansible
#
#   or simply type `. .bash_aliases_ansible` for one time using
#
