Ansible commands

Ansible Commands:

ansible all -m ping -u mysql -k
ansible-playbook mysql8.yml -k -vvv
ansible-playbook mysql8.yml -vvv
ansible-galaxy - command to manage Ansible roles in shared repostories
ansible-config - View, edit, and manage ansible configuration
ansible-console - a REPL that allows for running ad-hoc tasks against a chosen inventory
ansible-doc - displays  information  on  modules  installed in Ansible libraries.  It displays a terse listing of plugins and their short descriptions, provides a printout of their DOCUMENTATION strings
ansible-inventory - used to display or dump the configured inventory as Ansible sees it
ansible-playbook - the tool to run Ansible playbooks, which are a configuration and multinode deployment system.
ansible-pull - is  used  to up a remote copy of ansible on each managed node, each set to run via cron and update playbook source via a source repository.  This inverts the default push architecture of ansible into a pull architecture, which has near-limitless scaling potential.
ansible-vault - can  encrypt  any structured data file used by Ansible.

Use user defined inventory location using -i:
$ ansible-playbook <yaml_file_name>.yml -i /<path_to_hosts_file>/hosts
