Ansible: insert a single word on an existing line in a file

Question

I have to use Ansible modules in order to edit the /etc/ssh/sshd_config file - every time I create a new user I want to append it at these two lines:

AllowUs         


        

Answer 1

This worked for me

 - name: Add Group to AllowGroups
   lineinfile: 
     dest=/etc/ssh/sshd_config
     backup=True
     backrefs=True
     state=present
     regexp='^(AllowGroups(?!.*\b{{ groupname }}\b).*)$'
     line='\1 {{ groupname }}'
