Hi,
I stumbled onto little mind game with ansible today : D .
I have three roles that are tagged.
- hosts: vagrant
> sudo: yes
> roles:
> - {role: ansible_users, tags: users}
> - {role: ansible_nginx, tags: nginx}
> - {role: ansible_mysql, tags: mysql}
>
I have defaults/main.yml for "ansible_users" and "ansible_mysql" in their
respective places.
This is "ansible_users" defaults:
---
> users:
> - user: detlic
> webdir:
> - woodpecker
> - aligator
> - user: keder
> webdir: []
>
This is "ansible_mysql" defaults:
---
> users:
> - user: detlic
> db:
> - aligatordb
> - woodpeckerdb
> - user: jazavac
> db:
> - badgerdb
> - ddaybdb
>
I have left NGINX role without "defaults". How I understand things is that
NGINX will inherit "defaults" vars from other roles and use them where it
can. But in this case {{ VARS }} are named the same in both USER and MYSQL
roles.
NGINX role is before MYSQL from whoom it should inherit vars? In my test
case it inherits it from the LAST role in the list. So in this case it is
MYSQL. If I remove MYSQL role from a list then everything is fine.
Another thing is if I leave MYSQL role present BUT use TAGS and play roles
with jsut USERS and NGINX tags, still NGINX inherits "defaults" from MYSQL.
Can someone comment on this.
