ansible run list of roles with loop

Question

I have main file, that can initiate different individual roles.

---
- hosts: all
  gather_facts: False
  roles:
    - role: "{{ rnames }}"
...

when I run individual roles, it runs fine

ansible-playbook -i inv initiate.yml -e rnames=install_packages

But what I prefer is to run multiple roles, by providing a list of roles to rname variable

ansible-playbook -i inv initiate.yml -e rnames=install_packages,config_merge

I tried with_items & loop constructs, but can't seem to figure out.

Answer 1

Use include roles in a loop. For example, you'll have to split the comma-separated list of roles

  tasks:
    - include_role:
        name: "{{ item }}"
      loop: "{{ rnames.split(',') }}"
