Ansible ad-hoc commands

Create an inventory file

[host1.something]
[host2.something]
[group1]
group1host.something
group2host.something

Run a command on all hosts ansible -i inventory_file all -m command -a "uptime"

This specifies the inventory file (-i) run on all hosts (all) and run the command module (runs a remote command) with the module argument uptime (-a)

Run a command on all hosts simpler ansible -i inventory_file all  -a "uptime"

Same as above.  Notice that the module name was not specified as the command module is used by default

Run a command on hosts in group1 with sudo ansible -i inventory_file group1 -s -K -a "service rsyslog status"

-s Use sudo

-K ask for the sudo password (can be omitted if not required)

Copy a file to all hosts ansible -i inventory_file all -m copy -a "src=\~/.vimrc dest=\~"
