I’m learning Ansible and other things from this guide [https://github.com/Artemmkin/infrastructure-as-code-tutorial/blob/master/docs/06-ansible.md](https://github.com/Artemmkin/infrastructure-as-code-tutorial/blob/master/docs/06-ansible.md) Only problem is whenever I try and run deply.yml I get ` [WARNING]: provided hosts list is empty, only localhost is available.

I can post my hosts.yml deply.yml and ansiblecfg if needed, but all that same info is in the guide I linked. Any help would be very much appreciated as I’m a noob when It comes to Ansible and I really want to learn it better. ---

You would need to, if not we are left to speculate and guess and that is not very productive. > Any help would be very much appreciated as I'm a noob when It comes to > Ansible and I really want to learn it better. The important thing when you need help is to provide as much information that you can. A little to much information is better then to little. ---

You are missing a colon after raddit-instance. ---

Ohhhh, this is why you don’t do this after 2am at night XD. Sadly it’s still giving me that error even after I added the colon :/, clearly I’m missing something still ---

If all three files is in the same directory and you are in that directory when running "ansible-playbook deploy.yml" it should work. ---

Yeah all files are in the same directory and I’m running it from that directory. Yet for some odd reason it’s still giving me that error, I’m wondering if I should setup a fresh vm with ansible to test it on that. The error again just to show it’s the same ` [WARNING]: provided hosts list is empty, only localhost is available.
