How to create basic loop using with inline dictionary items variables in ansible playbook?

In Ansible, you can create a loop using the with_items keyword and pass an inline dictionary to it. Here’s an example of how to create a basic loop using inline dictionary items variables in an Ansible playbook:

Example:1

- name: Example of a loop with inline dictionary items
  hosts: all
  vars:
    my_dict:
      item1: value1
      item2: value2
      item3: value3
  tasks:
    - name: Print dictionary items
      debug:
        msg: "{{ item.key }}={{ item.value }}"
      with_items: "{{ my_dict|dict2items }}"

In this example, we define a dictionary called my_dict with three key-value pairs. We then use the dict2items filter to convert the dictionary to a list of dictionaries with key and value keys. We pass this list to the with_items keyword to create a loop.

Within the loop, we use the item.key and item.value variables to print out the current key-value pair. The debug module will be called once for each key-value pair in the dictionary, resulting in the following output:

ok: [localhost] => (item={'key': 'item1', 'value': 'value1'}) => {
    "msg": "item1=value1"
}
ok: [localhost] => (item={'key': 'item2', 'value': 'value2'}) => {
    "msg": "item2=value2"
}
ok: [localhost] => (item={'key': 'item3', 'value': 'value3'}) => {
    "msg": "item3=value3"
}

As you can see, the loop iterates over each key-value pair in the dictionary and prints out the key and value for each pair.

Example:2

Create a ansible config file as ansible.cfg file in your project directory:

[defaults]  
inventory = hosts  

Create a hosts file as hosts in the project directory

[webservers]
ansnode1 ansible_ssh_host=192.168.56.202 ansible_python_interpreter=/usr/bin/python   
ansnode2 ansible_ssh_host=192.168.56.203 ansible_python_interpreter=/usr/bin/python   

[webservers:vars]
ansible_port=22  
http_port=8080  


[dbservers]
ansnode3 ansible_ssh_host=192.168.56.204 ansible_python_interpreter=/usr/bin/python    
ansnode4 ansible_ssh_host=192.168.56.205 ansible_python_interpreter=/usr/bin/python   

[dev:children]
webservers  
dbservers  

Create a file named called as user_playbook.yml in your project directory

# the minus in YAML this indicates a list item. The playbook contains a list
#of plays, with each play being a dictionary
- hosts: webservers 
  tasks: 
    - name: add several users 
      user: 
        name: "{{ item.name }}"
        state: present 
        groups: "{{ item.groups }}" 
      with_items: 
        { name: 'testuser1', groups: 'wheel' }
        { name: 'testuser2', groups: 'root' } 
# Three dots indicates the end of YAML document
