Ansible Collection l3d.users

Ansible collection for managing users, groups, SSH keys and more.

There are several ansible roles in this collection. Together they can set up a Unix system with proper users, groups and, if needed, superpowers. The user can be given SSH keys or a password. It is also possible to restrict login via SSH to the defined users. And it is also possible to delete users.

Ansible Roles:

Please note, it is pretty useless to add an ssh key to an non-existing user directory. So please add users first before running other roles

• l3d.users.user: roles/user
• l3d.users.admin: roles/admin
• l3d.users.sshd: roles/sshd
• l3d.users.dotfiles: roles/dotfiles

Using this Collection

You can install the collection using ansible-galaxy by running:

ansible-galaxy collection install l3d.users:1.1.1

Remember you can to Upgrade to the latest version of the l3d.git collection using the --upgrade parameter:

ansible-galaxy collection install l3d.users --upgrade

Or you could clone this collection in your local ansible project for example to collections/ansible_collections/l3d/users/.

# Clone git Repo to specified path
git clone https://github.com/roles-ansible/ansible_collection_users.git collections/ansible_collections/l3d/users/

# change directory
cd collections/ansible_collections/l3d/users/

# optionally install all requirements
ansible-galaxy collection install -r requirements.yml --upgrade

You can also list a collection in requirements.yml:

---
collections:
  - name: l3d.users
    version: ">=1.1.1"
