Ansible ad hoc command examples
Ansible is a powerful automation tool that allows for easy configuration management, application deployment, and task automation. One of the most useful features of Ansible is its ad hoc command capability. Ad hoc commands allow you to quickly run a single command on one or multiple remote hosts without the need for a playbook. In this blog post, we will explore some Ansible ad hoc command examples.
Command
ansible group001 -i hosts.ip -m shell -a "run some shell command" --become -f 1 -v
ansible-playbook -i /path/to/my_inventory_file -u my_connection_user -k -f 3 -T 30 -t my_tag -m /path/to/my_modules -b -K my_playbook.yml
