Playbook to add hosts to the known hosts list - Ansible

Question

How do I write Ansible Playbook to add hosts to the known host list?

Answer 1

Hey @Kiran, try something like this:

- name: Add EC2 instances as known hosts
  known_hosts:
    name: "{{ item.public_ip }}"
    key: "{{ lookup('pipe', 'ssh-keyscan -t rsa ' + item.public_ip) }}"
  with_items: "{{ ec2_instances.tagged_instances }}"
