Ansible - Adhoc Run

• The command module is used by default if nothing else is specified.
• Prompting for connection password isn’t needed if you use an SSH key

Super simple examples:

ansible all -m ping -u user1 -k
ansible all -a "uname -a" -k

Use sudo for root perms and prompt for both connection password and sudo password:

ansible all -a "cat /etc/shadow" -bkK

Common useful options:

--become ( -b )       ( typcially sudo for root )
--ask-pass  ( -k )
--ask-become-pass  ( -K )   # prompt for become password
--become_user=produser      # doesn't imply --become
--become-method=su          # sudo is default
--check -C

-u user1   # connect as a user
-f 10      # 10 parallel forks

More examples:

ansible host1 -a "/sbin/reboot" -bkK
ansible prod1 -a "/sbin/reboot" -bkK
ansible webhosts -a "/sbin/reboot" -bkK -f 10 -u testuser # 10 parallel forks

ansible db -m ansible.builtin.copy -a "src=/etc/hosts dest=/tmp/hosts"
ansible webservers -m ansible.builtin.file -a "dest=/opt/data/b.txt mode=600 owner=user1 group=user1"
ansible webservers -m ansible.builtin.file -a "dest=/opt/data mode=755 owner=user1 group=user1 state=directory"

Show all facts:

ansible all -m ansible.builtin.setup
