Ansible - Creating users and copying ssh keypair files to the remote server

gistfile1.txt

Put this in your `local-configure.yml` file, add as many users as you need:

    users:
      - name: fulvio
        sudoer: yes
        auth_key: ssh-rsa blahblahblahsomekey this is actually the public key in cleartext
      - name: plone_buildout
        group: plone_group
        sudoer: no
        auth_key: ssh-rsa blahblahblah ansible-generated on default
        keyfiles: keyfiles/plone_buildout

In your playbook root folder, create a folder `keyfiles`.  In it, create a subfolder for 
each username for which you want to copy keyfiles to the server.  Put the private and public key files,
as well as any other files, such as `known_hosts` in the user subfolder.

Add the follwing line in `playbook.yml` under `roles:` (e.g. right under `- role: ANXS.hostname`):

    - role: create_users

Copy the gist file `main.yml` to `/roles/create_users/tasks`.

Now run your playbook.
That's it!

main.yml

Hello,

Could you please review below code and let me know what is missing?

Requirement: Add multiple users along with their home directories & ssh_keys, authorized_keys2 files to each, do let me know if you have any questions.

Add users & keys to destination servers

• hosts: lb:app2
  tasks:
  • name: Add list of users
    user:
    name: "{{ item.name }}"
    uid: "{{ item.uid }}"
    groups: "{{ item.groups }}"
    comment: "{{ item.comment }}"
    password: " {{ item.password }}"
    state: present
    with_items:
    • { name: testuser1, uid: 1002, groups: "wheel, automate", comment: "{{ 'AM Admin ID' }}", password: "{{ '$6$wsix5/A0$Qs46M8HtJXzcpA/ZnvagCPmiXsxl4ifzn.' }}" }
    • { name: testuser2, uid: 1003, groups: "automate", comment: "{{ 'HM Admin ID' }}", password: "{{ '$6$gs3YJV06SUyD89ZNioh2IfVmC14bbqFWWpfC9E/' }}" }
