In a playbook , I gathered the user key into the variable "user_key" and
using a add_host module to login to the server and execute the required
tasks .
- name: Writing the key to a file
ansible.builtin.copy:
content: "{{ user_key }}"
dest: /tmp/new_inst.pem
mode: '0600'
follow: yes
register: keyfile
- name: create a temp inventory
ansible.builtin.add_host:
hostname: '{{ servera }}'
groups: mygroup
ansible_ssh_private_key_file: "{{ keyfile.dest }}"
ansible_ssh_user: "root"
ansible_ssh_extra_args: '-o StrictHostKeyChecking=no'
- name: validate the httpd in new hosts
hosts: mygroup
gather_facts: true
become: yes
environment:
ANSIBLE_HOST_KEY_CHECKING: "False"
tasks:
- name: Start service httpd, if not started
service:
name: httpd
state: started
All works fine using the above.
However is there an option to read the content of the key directly , read
the contents of the keyfile to the add_host module with something like
"ansible_ssh_private_key" ??
I want to avoid writing the key to a file, chmod 600 and then remove it
after execution.
Also , is there a way to read the variable "user_key" when manually
feed during the ansible-playbook command , like for the same above codes
usage .
# ansible-playbook playbook -e "user_key={{ssh_content}}"
where ssh_content is a python variable which have the exact key_value
details from another program output .
