Error: "skipping: no hosts matched"

There can be multiple reasons this happens, so we’ll step through all of them. We’ll start by assuming you’re running the command

ansible-playbook galaxy.yml

The following things can cause issues:

1. Within your galaxy.yml, you’ve referred to a host group that doesn’t exist or is misspelled. Check the hosts: galaxyservers to ensure it matches the host group defined in the hosts file.
2. Vice-versa, the group in your hosts file should match the hosts selected in the playbook, galaxy.yml.
3. If neither of these are the issue, it’s possible Ansible doesn’t know to check the hosts file for the inventory. Make sure you’ve specified inventory = hosts in your ansible.cfg.
