Good afternoon everyone, I have a problem because I couldn’t find a similar task to validate mine. I want to export the public key to some machines. I appreciate your attention and help if anyone has already done or gone through the same thing. Below is an example of what I’m trying. Thank you.

* * *

- name: Ansible Checksum, Backup, Validate  
hosts: hosts01  
tasks:  
#Checksum
  - name: Deploy WAR file to Tomcat  
copy:  
src: ~/home/vagrant/.ssh/id\_rsa.pub  
dest: /home/root/.ssh  
checksum: “{{ lookup(‘file’, ‘~/home/vagrant/.ssh/id\_rsa.pub’) | hash(‘sha256’) }}”  
become: true
