Ansible - accessing local environment variables

Those variables are in the management machine I suppose source machine in your case.

Check this: https://docs.ansible.com/ansible/devel/collections/ansible/builtin/env_lookup.html

Basically, if you just need to access existing variables, use the ‘env’ lookup plugin. For example, to access the value of the HOME environment variable on management machine:`

Now, if you need to access it in the remote machine you can just run your ansible script locally in the remote machine. Or you could just the ansible facts variables. If it's not in the ansible facts you can just run a shell command to get it.

Use ansible lookup:

- set_fact: env_var="{{ lookup('env','ENV_VAR') }}"

I have a Linux vm running on osx, and for me:

lookup('env', 'HOME') returns "/Users/Gonzalo" (the HOME variable from osx), while ansible_env.HOME returns "/root" (the HOME variable from the vm).

Worth to mention, that ansible_env.VAR fails if the variable does not exists, while lookup('env', 'VAR') does not fail.
