Ansible script to copy file based on date

I have created below playbook to archive log files on remote server. The script perform based on the key work in the host file.

tasks:
 - name: Create a tar.gz archive of log files.
   archive:
     path:
        - "{{item.path}}"
     dest: "{{item.dest}}"
     format: gz
     force_archive: yes
     owner: ubuntu
   become: true
   when: "inventory_hostname is search(item.key)"
   with_items: 
       - {path: "/var/log/grafana/grafana.log", dest: "/tmp/grafana.log.gz", key: "grafana"}

Is it possible to archive the files based on a date variable. For example, if I pass the date 11-11-2020 at the time of execution, then the script has to archive only the file created at this date?

  • Create a var with all log files.
  • Use stat module to retrieve facts for files, this module reaturns ctime value wich is Time of last metadata update or creation (depends on OS) and register the return values on a variable.
  • In archive task use wiht_nested with files and file_data with a when condition where validate the items of both are the same and the ctime is equal to a date variable.
  • Execute playbook sending date variable as extra-vars.

playbook.yml

- name: Archive files
  hosts: all
  gather_facts: no
    
  vars:
    files:
      - {path: "/home/vagrant/l1.txt", dest: "/tmp/grafana.log.gz", key: "grafana"}
      - {path: "/home/vagrant/l2.txt", dest: "/tmp/grafana.log.gz", key: "grafana"}
      - {path: "/etc/host.conf", dest: "/tmp/grafana.log.gz", key: "grafana"}
    
  tasks:
  - name: Get file data
    stat:
      path: "{{ item.path }}"
    with_items: "{{ files }}"
    register: file_data
    
  - name: Create a tar.gz archive of log files.
    archive:
      path: "{{item[0].path}}"
      dest: "{{item[0].dest}}"
      format: gz
      force_archive: yes
      owner: ubuntu
    become: true
    when: "inventory_hostname is search(item[0].key) and item[0].path == item[1].stat.path and  '%d-%m-%Y' | strftime(item[1].stat.ctime) == {{ date }}"
    with_nested:
      - "{{ files }}"
      - "{{ file_data.results }}"

Execute playbook

ansible-playbook playbook.yml -i inventory -e "date='11-11-2020'"
