# user-setup

## Prerequisites

- Setup Ansible: follow the [installation](../README.md#installation) guide to setup ansible on your machine.

- Setup a remote machine with passwordless SSH login for the root user

- Install `passlib` used for handling encrypted passwords when setting up a user

  ```bash
  pip install passlib
  ```

## Setup a user

Execute the following commands in the `user-setup` directory

- Create a new `hosts.ini` file:

   ```bash
   cp ../hosts.example.ini hosts.ini
   ```

- Edit the [`hosts.ini`](./hosts.ini) file:

  ```ini
  [deployment_host]
  <host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
  ```

  - Replace `<host_name>` with the desired `hostname` of the remote machine
  - Replace `<target_ip>` with the IP address or hostname of the target machine
  - Replace `<ssh_user>` with `root`

- Verify that you are able to connect to the host using the following command:

  ```bash
  ansible all -m ping -i hosts.ini

  # Expected output:

  # <host_name> | SUCCESS => {
  #  "ansible_facts": {
  #      "discovered_interpreter_python": "/usr/bin/python3.10"
  #  },
  #  "changed": false,
  #  "ping": "pong"
  # }
  ```

- Setup `user-vars.yml`  using the example file

  ```bash
  cp user-vars.example.yml user-vars.yml
  ```

- Edit the `user-vars.yml` file:

  ```bash
  # name of the user you want to setup on the target host
  username: ""

  # password of the user you want to setup on the target host
  password: ""

  # path to the ssh key on your machine, eg: "/home/user/.ssh/id_rsa.pub"
  path_to_ssh_key: ""
  ```

- Execute the `setup-user.yml` Ansible playbook to create a user with passwordless sudo permissions:

  ```bash
  LANG=en_US.utf8 ansible-playbook setup-user.yml -i hosts.ini
  ```
