Reticulum

A hybrid game networking and web API server, focused on Social Mixed Reality.

Development

1. Install Prerequisite Packages:

PostgreSQL (recommended version 11.x):

Linux:

On Ubuntu, you can use

apt install postgresql

Otherwise, consult your package manager of choice for other Linux distributions

Windows: https://www.postgresql.org/download/windows/

Windows WSL: https://github.com/michaeltreat/Windows-Subsystem-For-Linux-Setup-Guide/blob/master/readmes/installs/PostgreSQL.md

Erlang (v22) + Elixr + Phoenix

https://elixir-lang.org/install.html

https://hexdocs.pm/phoenix/installation.html

Ansible

https://docs.ansible.com/ansible/latest/installationguide/introinstallation.html

2. Setup Reticulum:

Run the following commands at the root of the reticulum directory:

1. mix deps.get

2. mix ecto.create

   • If step 2 fails, you may need to change the password for the

     postgres

     role to match the password configured

     dev.exs

     .
   • From within the

     psql

     shell, enter

     ALTER USER postgres WITH PASSWORD 'postgres';

   • If you receive an error that the

     ret_dev

     database does not exist, (using psql again) enter

     create database ret_dev;

3. from the

   assets

   directory,

   npm install

4. From the project directory

   mkdir -p storage/dev

3. Start Reticulum

Run

scripts/run.sh

iex -S mix phx.server

Run Hubs Against a Local Reticulum Instance

1. Setup the

hubs.local

hostname

When running the full stack for Hubs (which includes Reticulum) locally it is necessary to add a

hosts

hubs.local

On MacOS or Linux:

nano /etc/hosts

From there, add a host alias

Example:

bash
127.0.0.1   hubs.local

2. Setting up the Hubs Repository

Clone the Hubs repository and install the npm dependencies.

git clone https://github.com/mozilla/hubs.git
cd hubs
npm ci

3. Start the Hubs Webpack Dev Server

Because we are running Hubs against the local Reticulum client you'll need to use the

npm run local

hubs

4. Navigate To The Client Page

Once both the Hubs Webpack Dev Server and Reticulum server are both running you can navigate to the client by opening up:

https://hubs.local:4000?skipadmin

The

skipadmin

is a temporary measure to bypass being redirected to the admin panel. Once you have logged in you will no longer need this.

5. Logging In

To log into Hubs we use magic links that are sent to your email. When you are running Reticulum locally we do not send those emails. Instead, you'll find the contents of that email in the Reticulum console output.

With the Hubs landing page open click the Sign In button at the top of the page. Enter an email address and click send.

Go to the reticulum terminal session and find a url that looks like https://hubs.local:4000/?authorigin=hubs&authpayload=XXXXX&auth_token=XXXX

Navigate to that url in your browser to finish signing in.

6. Creating an Admin User

After you've started Reticulum for the first time you'll likely want to create an admin user. Assuming you want to make the first account the admin, this can be done in the iex console using the following code:

Ret.Account |> Ret.Repo.all() |> Enum.at(0) |> Ecto.Changeset.change(is_admin: true) |> Ret.Repo.update!()

7. Start the Admin Portal server in local development mode

When running locally, you will need to also run the admin portal, which routes to hubs.local:8989 Using a separate terminal instance, navigate to the

hubs/admin

npm run local

You can now navigate to https://hubs.local:4000/admin to access the admin control panel

Run Spoke Against a Local Reticulum Instance

1. Follow the steps above to setup Hubs
2. Clone and start spoke by running

   ./scripts/run_local_reticulum.sh

   in the root of the spoke project
3. Navigate to https://hubs.local:4000/spoke

Run Reticulum against a local Dialog instance

1. Update the Janus host in

   dev.exs

   :

   dev_janus_host = "hubs.local"
   

2. Update the Janus port in

   dev.exs

   :

   config :ret, Ret.JanusLoadStatus, default_janus_host: dev_janus_host, janus_port: 4443
   

3. Add the Dialog meta endpoint to the CSP rules in

   add_csp.ex

   :

default_janus_csp_rule =
   if default_janus_host,
      do: "wss://#{default_janus_host}:#{janus_port} https://#{default_janus_host}:#{janus_port} https://#{default_janus_host}:#{janus_port}/meta",
      else: ""

1. Edit the Dialog configuration file turnserver.conf and update the PostgreSQL database connection string to use the coturn schema from the Reticulum database:

   psql-userdb="host=hubs.local dbname=ret_dev user=postgres password=postgres options='-c search_path=coturn' connect_timeout=30"
