Create a new group x and users a and b on the target server (192.168.100.251) using Ansible,
I want to attach a and b to x, but I get an error. The OS is CentOS7 for both Ansible operation terminal and target server.

  

user_groups:
  '-{name:' x ', gid: 100}

  

users:
  '-{name:' a ', uid: 123, group:' x '}
  '-{name:' b ', uid: 124, group:' x '}
