title: Ansible: no hosts matched
body: <p>I'm trying to execute my first remote shell script on Ansible. I've first generated and copied the SSH keys. Here is my yml file:</p>
  
  <pre><code>---
  - name: Ansible remote shell
    hosts: 192.168.10.1
    user: myuser1
    become: true
    become_user: jboss
    tasks:
      - name: Hello server
        shell: /home/jboss/script.sh
  </code></pre>
  
  <p>When launching the playbook however, the outcome is "no hosts matched":</p>
  
  <pre><code>ansible-playbook setup.yml 
  
  PLAY [Ansible remote shell
  ******************************************** 
  skipping: no hosts matched
  
  PLAY RECAP ******************************************************************** 
  </code></pre>
  
  <p>I've tried also using the host name (instead of the IP address), however nothing changed. Any help ?</p>
