Ansible

This is a very frequently used automation tool. Here are simple hints for usage.

An example of command line usage:

 
    
ansible -m ping all                                        -- will check all known hosts and collect details
ansible-playbook inst-software.yml -t firefox              --will run install-software playbook using the tag "firefox" to install it
ansible-playbook inst-rsync -l webserver1                  --will run install-rsync playbook only on host webserver1
ansible-plabyook inst-apache --extra-vars '{"version":"2.4"}' -- will use manually added version variable
