I wonder how to copy my SSH public key to many hosts using Ansible.
First attempt:
ansible all -i inventory -m local_action -a "ssh-copy-id {{ inventory_hostname }}" --ask-pass
But I have the error The module local_action was not found in configured module paths
.
Second attempt using a playbook:
- hosts: all
become: no
tasks:
- local_action: command ssh-copy-id {{ inventory_hostname }}
Finally I have entered my password for each managed host:
ansible all -i inventory --list-hosts | while read h ; do ssh-copy-id "$h" ; done
How to fill password only once while deploying public SSH key to many hosts?
EDIT: I have succeeded to copy my SSH public key to multiple remote hosts using the following playbook from the Konstantin Suvorov's answer.
- hosts: all
tasks:
- authorized_key:
key: "{{ lookup('file', '~/.ssh/id_rsa.pub') }}"
The field user
should be mandatory according to the documentation but it seems to work without. Therefore the above generic playbook may be used for any user when used with this command line:
ansible-playbook -i inventory authorized_key.yml -u "$USER" -k
Why don't you use authorized_key module?
- hosts: all
tasks:
- authorized_key:
user: remote_user_name
state: present
key: "{{ lookup('file', '/local/path/.ssh/id_rsa.pub') }}"
and run playbook with -u remote_user_name -k
