## Setup Ansible

To get started, follow the [installation](../README.md#installation) guide to setup ansible on your machine

## Configure DNS

### Prerequisites

- Buy a domain and configure nameservers to DigitalOcean

- Generate a DigitalOcean access token

### Create DNS entries in DigitalOcean

- Copy the [`dns-vars.example.yml`](./vars/dns-vars.example.yml) file

  ```bash
  cd vars/
  cp dns-vars.example.yml dns-vars.yml
  ```

- Set the following values in the `dns-vars.yml` file

  ```bash
  # primary domain for which DNS records will be managed
  # eg: laconic.com
  domain: ""

  # specific prefix for subdomains
  # eg: lcn-cad
  subdomain_prefix: ""

  # The IP address to be used for the A record of the cluster control machine
  # eg: 23.111.78.179
  cluster_control_ip: ""

  # DigitalOcean access token
  # eg: dop_v1...
  do_api_token: ""
  ```

- Run the [`setup-dns.yml`](./setup-dns.yml) ansible playbook to create the necessary DNS entries in DigitalOcean

  ```bash
  ansible-playbook setup-dns.yml
  ```

## Setup User `dev`

- Create a new `hosts.ini` file:

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

- Edit the [`hosts.ini`](./hosts.ini) file to run the playbook on a remote machine:

  ```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 -k

  # Expected output:

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

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

  ```bash
  ansible-playbook setup-user.yml -i hosts.ini --extra-vars='{ "target_host": "deployment_host" }'
  ```
