 tasks:
 - name: Install a list of packages
   apt:
    name: "{{ item }}"
    update_cache: yes
    state: present
   with_items:
    - 'git'
    - 'apache2'
    - 'docker-ce'

 tasks:
 - name: Only run "update_cache=yes" if the last one is more than 3600 seconds ago
   apt:
    update_cache: yes
    cache_valid_time: 3600

Here Ansible will not update the cache if it’s been updated in the last 3600 seconds. Ansible will compare last updated time with this task executed time. If the time gap is less than 3600 seconds it will skip this task. If the time gap is greater than 3600 seconds it will update the cache.

update_cache will updates the list of available packages and their versions, i,e it will update apt's database /etc/apt/sources.ist. Fetches the list of available updates.

ansible apt module upgrade

 tasks:
