Host variables

We can further separate out the host variables in the same format as the group variables:

$ mkdir host_vars

In our case, we execute the commands on the localhost, therefore the file under host_vars should be named accordingly, such as host_vars/localhost. Note that we kept the variables declared in group_vars.

    ---    "nexus_devices":      "nx-osv-1":        "hostname": "nx-osv-1"        "username": "{{ username }}"        "password": "{{ password }}"        <skip>        "netflow_enable": True      "nx-osv-2":        "hostname": "nx-osv-2"        "username": "{{ username }}"        "password": "{{ password }}"        <skip>

After we separate out the variables, the playbook now becomes very lightweight and only consists of the logic of our operation:

    $ cat chapter5_9.yml    --- - name: Ansible Group ...
