tags

• terkadang kita hanya ingin menjalankan task-task tertentu yang ada di suatu playbook
• contohnya misal task 1 menginstall web server dan task 2 mencopy file html
  • kita sudah tahu bahwa web server sudah terinstall di semua host,
  • jadi kita hanya ingin menjalankan task 2 untuk menghemat waktu
• untuk mengatasi masalah ini kita dapat menggunakan tags
  • nantinya setiap task bisa memiliki beberapa tag

template

tasks:
- name: Install the servers
  ansible.builtin.yum:
    name:
    - httpd
    - memcached
    state: present
  tags:
  - packages
  - webservers

- name: Configure the service
  ansible.builtin.template:
    src: templates/src.j2
    dest: /etc/foo.conf
  tags:
  - configuration

example

  hosts: node_docker
  become: true
  gather_facts: true # defaultnya memang true
  vars: # mendefinisikan variable

• untuk menjalankan task tertentu kita dapat menggunakan --tags <tag1>,<tag2>
• untuk menjalankan task selain yang ditentukan dapat menggunakan option --skip-tags <tag1>,<tag2>

command

ansible-playbook <nama_file.yaml> --check --tags copy_file
