Ansible- Tags

Ansible – Tags

If you have a large playbook, it becomes useful to be able to run only a specific part of it rather than running everything in the playbook. Ansible supports a tag attribute for this reason.

When you apply tags on things, then you can control whether they are executed by adding command-line options.

When you execute a playbook, you can filter tasks based on the tags in two ways, such as:

  1. On the command line, with the -tags or -skip-tags options.

  2. In Ansible configuration settings, with the TAGS_RUN and TAGS_SKIP options.

an example that tags two tasks with different tags, such as:

tasks:  
- yum:  
    name: ""  
    state: present  
  loop:  
  - httpd  
  - memcached  
  tags:  
  - packages  
  
- template:  
    src: templates/src.j2  
    dest: /etc/foo.conf  
  tags:  
  - configuration

If you want to run the configuration and packages part of a very long playbook, then you can use the -tags option on the command line.
ansible-playbook example.yml --tags "configuration,packages"

if you want to run a playbook without certain tagged tasks, then you can use the -skip-tags command-line option.

ansible-playbook example.yml --skip-tags "packages"
