Including other playbooks
- Including other playbooks in current playbook execution
- Ansible provides two options for executing other playbooks
- include playbooks
- import playbooks
- Major difference b/w include and import tasks are
- import tasks will be parsed at the begining when you run the playbook
- include tasks will be parsed at the moment ansible hits
- Refer Here for the initial changeset with include
- Refer Here for the initial changeset with import
- Refer Here
- For variable usage Refer Here
- In ansible playbooks we can use tags Refer Here for the changeset
- Creatng reusable assets with include and import is a challenging job, Ansible has included roles to create reusability
- Roles move beyond the basic structure of playbooks and provide a framework for fully independent or interdependent, collection of variables, files, tasks, templates and modules
- Refer Here for official docs
- Ansible role directory structure Refer Here
- Refer Here this changeset for sample role structure
- Refer Here for the tomcat-ubuntu role created
- Now lets see how to use these roles
- Refer Here to view the usage of roles
- These roles gives us flexibility to use lot of alreay written open source community roles which are hosted by ansible in Ansible Galaxy
- Lets install mysql on ubuntu using ansible role from galaxy Refer Here
- Refer Here for the change set
- Now run the ansible-playbook and the mysql service will be installed on the nodes
- Now lets add some more roles to ansible-playbook
- Refer Here for the changeset
