# service-provider-setup

## Setup Ansible

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

## Setup a new User

- 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

  # 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
  cd vars
  cp user-vars.example.yml user-vars.yml
  ```

- Edit the following vars:

  ```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
  path_to_ssh_key: "
  ```

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

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

## Become a Service Provider

### Prerequisites

- Buy a domain and configure nameservers to DigitalOcean

- Generate a DigitalOcean access token

- Create a PGP key on your target host

  ```
  gpg --full-generate-key
  ```

- List the secret keys

  ```
  gpg --list-secret-keys --keyid-format=long
  ```

- This will output something like this

  ```
  [keyboxd]
  ---------
  sec   rsa4096/0AFB10B643944C22 2024-05-03 [SC] [expires: 2025-05-03]
        17B3248D6784EC6CB43365A60AFB10B643944C22
  uid                 [ultimate] user <hello@laconic.com>
  ```

  Note the `0AFB10B643944C22` sequence of characters after `sec`. This will be required later.

- Copy the vars files:

  ```bash
  cd vars
  cp dns-vars.example.yml dns-vars.yml
  cp k8s-vars.example.yml k8s-vars.yml
  cp container-vars.example.yml container-vars.yml
  cp webapp-vars.example.yml webapp-vars.yml
  ```

- Update the following values in the respective variable files:

  ```bash
  # vars/dns-vars.yml
  full_domain: ""               # eg: laconic.com
  subdomain_prefix: ""          # eg: lcn-cad
  cluster_control_ip: ""        # eg: 23.111.78.179
  do_api_token: ""              # eg: dop_v1...

  # vars/k8s-vars.yml
  target_host: "deployment_host"
  gpg_key_id: ""                # The sequence obtained in the previous step, eg: 0AFB10B643944C22
  vault_passphrase: ""          # passphrase for GPG key
  org_id: ""                    # eg: lcn
  location_id: ""               # eg: cad
  base_domain: ""               # eg: laconic
  support_email: ""             # eg: support@laconic.com

  # vars/container-vars.yml
  container_registry_username: "" # username to login to the container registry
  container_registry_password: "" # password to login to the container registry

  # vars/webapp-vars.yml
  authority_name: ""      # eg: my-org-name
  cpu_reservation: ""     # Minimum number of cpu cores to be used, eg: 2
  memory_reservation: ""  # Minimum amount of memory in GB to be used, eg: 4G
  ```

- Update `ansible_user` in the [`hosts.ini`](./hosts.ini) file to the user on target host

- Run the `service-provider-setup.yml` ansible-playbook to DNS records, deploy k8s, setup container registry, deploy the webapp-deployer API and webapp-deployer UI

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