Is the YAML file formatting correct throughout the example of the 'Inventory Variables' section? The difference in the relative indentation of webserver1 vs webserver2 doesn't seem too consistent with the initial presentation:

[web_servers]

web_server_1 ansible_user=centos http_port=80
web_server_2 ansible_user=ubuntu http_port=8080

Hello Jeff,

I tried a super simple playbook to read a dict variable:

---    
hosts: instance-01
vars:  
  vlans:
    id: 10
        
tasks: 
  - name: Read dict variable
    debug:
      msg: “{{ vlans[‘id’]  }}“

Output:

ansible-playbook test_dict.yml 
[WARNING]: Skipping unexpected key (servers) in group (local), only "vars", "children" and "hosts" are valid
ERROR! A playbook must be a list of plays, got a  instead

The error appears to be in ‘/home/student/Ansible/klooien/test_dict.yml’: line 2, column 1, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

—
hosts: instance-01
^ here

Help!

In reply to jef.

Hey Jeff, let me have a look at the playbook you are running to verify if the syntax is correct.

TASK [Get custom facts] **************************************************************************************************************************
fatal: [host2]: FAILED! => {“msg”: “The task includes an option with an undefined variable. The error was: ‘dict object’ has no attribute ‘date_time’\n\nThe error appears to be in ‘/rh294/chap4_setup_facts.yaml’: line 11, column 9, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n tasks:\n – name: Get custom facts\n ^ here\n”}

I am getting this error when i run the above custom fact. I am using ansible;

[root@control-node rh294]# ansible –version
