How do I make decision based on arch in Ansible playbooks?

Question

I have been trying to write playbooks where I can run different tasks based on the arch (i.e amd64, arm, ppc64le) that the playbook is running on. I can not figure out how do I get the arch of the system I am running it on.

How to figure out the arch of the system in Ansible playbook?

Answer 1

Ansible gathers suitable information from target hosts and stores it as facts, for example: ansible_architecture, ansible_os_family.

If you are in doubt, you can display all facts with the debug module and choose the ones that suit you best.

You can use the ansible_architecture facts in when conditions, and use it to include different task-files (an example to customise).
