Tagging tasks in Playbook

Tagging tasks in playbooks

Ansible “tags:” is an attribute in ansible-playbook.

If you have a large playbook it may become useful to be able to run a specific part of the

configuration without running the whole playbook.

When you execute a playbook, you can filter tasks based on tags.

Let's see an example,

Here I create a playbook for MySQL install and start running it using tags in this playbook,

[ansible@ansible1 ~]$ cat mysqld.yml

---

- hosts: single

become: yes

tasks:

- name: install mariadb-server

yum: name=mariadb-server state=latest

ignore_errors: yes

register: there

tags:

- packages

- name: start mariadb if there

service: name=mariadb state=started

register: running

tags:

- startup

My playbook is mysqld.yml, here I can use yum to install the MySQL-server latest version and start the service in that.

In that playbook I have added two tags one is ‘package’ and another one is ‘startup’.

Now we can run the playbook using the tags command,

[ansible@ansible1 ~]$ ansible-playbook mysqld.yml --tags "package” “startup"

Go back to the node machine and check service active or not.

Sudo systemctl status mysqld

Yes, it's started, running successfully!!.
