Ansible multiple hosts for a specific playbook?

normally in ansible you always define a specific host for a specific playbook. But what is if I want to run a playbook for multiple hosts?

For a bit more clarity: I have following groups:

  • Webservers
  • Dev Clients

and following playbooks:

  • install main software
  • install certbot
  • install nginx
  • install vscode

For obvious reasons for sure the nginx playbook should have the entry: hosts: Webservers but what is with the main software playbook. This playbook should include both hosts.

In the end I want to have many different playbooks and groups and the only thing I wanna execute is: ansible-playbook ~/playbooks/webservers.yml and this triggers: "main software, certbot, nginx..." via includes. But this doesn't work without editing the hosts section of every playbook that is included in the webservers.yml.

Is it possible to tell a playbook that it should run on the hosts from the main-playbook which has included it? like: webservers.yml -> hosts -> nginx.yml -> run on all clients which are entered in webservers.yml?

Does somebody of you has an idea? Or is this just not realizable with ansible?

You could use include module with when statement using group_names var as below:

webservers.yml

- hosts: all
  tasks:
    - name: Include Main Software playbook
      include: main_software.yml

    - name: Include Nginx playbook
      include: nginx.yml
      when: "'webservers' in {{ group_names }}"

    - name: Include Vscode playbook
      include: vscode.yml
      when: "'DevClients' in {{ group_names }}"

Remember main_software.yml, nginx.yml and vscode.yml playbooks must have a list of tasks not a play.
