Adduser with Ansible in Debian​

Ansible Adduser

This Ansible creates your desired user along with the public key and also places this user in the sudo group and add user to AllowUsers in ssh config.

Customizing files​

1.Change the remote_user in adduser.yaml.

##adduser.yaml

- name: Create user and add SSH key
  hosts: hosts
  remote_user: root
  become: yes


  vars_files:
  - values.yaml

  tasks:
  - name: Add the user
    ansible.builtin.user:
      name: "{{ username }}"
      password: "{{ password }}"
      shell: /bin/bash
      groups: sudo
      createhome: yes
     
  - name: Add the SSH public key
    authorized_key:
      user: "{{ username }}"
      key: "{{ lookup('file', ssh_public_key) }}"
      state: present


  - name: Add user to AllowUsers in sshd_config
    ansible.builtin.shell:
      cmd: "sed -i -e '/^AllowUsers/ s/$/ {{ username }}/' /etc/ssh/sshd_config"

  - name: Restart SSH server
    ansible.builtin.service:
      name: ssh
      state: restarted

2.Add the public key in id_rsa.pub.

##id_rsa.pub

ssh-rsa AAANZ5cZSQyc2EAANDAQA.....

3.Update the IP address and port in the inventory.

##inventory

[hosts]
192.168.100.20:4422

4.Change the username and password and public key path in values.yaml.

##values.yaml

username: YourUserName
password: $2y$10$G0l.owcCMBOtgmr9C/.55OBzliuFiHxD1wuDXuJsmIHJCWIXwFTxq
ssh_public_key: "/path/to/public/key/id_rsa.pub"
caution
