Organize roles - Ansible roles

Question

I have two hosts - host1 and host2

I need few packages to be installed on host1 and few on host2

host1

• rpm A
• rpm B
• rpm C

host2

• rpm A
• rpm B

How do I organize my roles to achieve this?

Answer 1

One of the ways is to use a generic packages role and pass the rpm to install to the role as a var

generators-playbook
   - roles:
       - { role: packages, packages: ["rpmA","rpmB"] }
executor-playbook
   - roles:
       - { role: packages, packages: ["rpmC"] }
