Importing multiple ansible playbooks

[Chris Bidwell - NOAA Federal]

Hi all,

Is there a way, or what is the syntax since I can't seem to find it on importing an ansible playbook and with that applying a specific tag to one or some of those playbooks?

---
# Add tsg keys
- import_playbook: tsg.yml
- import_playbook: tsgkey.yml
 
# Connect to RHSM
- import_playbook: capsule.yml
 
# Install Server environment for RHEL8
- import_playbook: rhel8_svr_env.yml

  - add tag here??  Doesn't work.
 
# Setup puppet
- import_playbook: chrony.yml
 
# Do updates
- import_playbook: cfu.yml
 
# Reboot after updates
- import_playbook: cfr.yml
 
# Install EPEL
- import_playbook: epel.yml

First you should read these pages that describe the difference between import vs include.

https://docs.ansible.com/ansible/2.9/user_guide/playbooks_reuse_includes.html

https://docs.ansible.com/ansible/2.9/user_guide/playbooks_reuse.html#tradeoffs-and-pitfalls-between-includes-and-imports

Do you want to import these playbooks and parse them once at load time, or "include" and parse them as they are encountered at run-time?

One reason to consider include vs import. If you have a when clause on an imported playbook, all the tasks within the playbook inherit that when clause and are evaluated individually. If you have a when clause on an included playbook, it applies to the include task itself (whether I include and execute the playbook). This can be a huge performance improvement.

Secondly you want to consider whether you want to include "playbooks" or "tasks" files. Task files inherit the inventory, become, gather_facts, etc of the parent playbook that includes them.
