Ansible: How to use inventory variables in ad-hoc commands

Question

I want to run an ad-hoc command over a host file, in the host file I have defined a variable for each host, How can I use that variable while executing an ad-hoc command.

For example:

ansible -i /home/bob/hosts_file -m shell -a "$VAR/project run"

I have defined the $VAR for each host in "hosts_file", the $VAR is different for every host in the inventory file. How can I use that variable in my ad-hoc command replacing for each host when executing.

Answer 1

Host variables are available to ansible, even while running an ad-hoc command. You insert them as you would through a playbook, using a jinja template.

ansible all -i /home/bob/hosts_file -m shell -a "{{var}}/project run"
