# CheSSH
|
|
|
|
CheSSH is a distributed multiplayer implementation of the game of Chess over SSH,
|
|
written in Elixir, with Discord integrations to deliver alerts when players are
|
|
looking for opponents, or in games when it is one's turn.

|
## Usage
|
|
|
|
### Dependencies
|
|
+ `npm`
|
|
+ `elixir`
|
|
+ `postgresql`
|
|
+ `redis` (which you can ignore if you only use the ETS backend for Hammer in
|
|
`config/dev.exs` [set by default])
|
|
|
|
### Installation
|
|
|
|
Do something among the lines of:
|
|
|
|
```
|
|
git clone https://github.com/Simponic/chessh
|
|
cd chessh
|
|
|
|
cp .env.example .env
|
|
chmod 0700 .env
|
|
|
|
# In one shell (after filling in your .env), start CheSSH
|
|
export $(cat .env | xargs)
|
|
mix ecto.create
|
|
mix ecto.migrate
|
|
iex -S mix
|
|
|
|
# In another shell, start the frontend
|
|
export $(cat .env | xargs)
|
|
cd front
|
|
npm install
|
|
npm start
|
|
```
|
|
|
|
## Architecture
|
|
The process of building the pi cluster is wholly contained in the awful
|
|
`buildscripts`, which will individually `ssh` into separate pi's and build the
|
|
services locally there as well as update the load balancer pi's configurations for nginx
|
|
and HAproxy.
|
|
|
|
More architecture talk of CheSSH can be found in my (albeit kinda cringe) FSLC
|
|
presentation on Elixir:

## Environment Variables (mostly optional)

|
|
CheSSH bot
|
|
+ `REACT_APP_DISCORD_OAUTH` is the link (after replacing the GET URL params) that will
|
|
be used to initiate discord OAUTH from the frontend
|
|
+ `CLIENT_REDIRECT_AFTER_OAUTH` & `SERVER_REDIRECT_URI` are self-explanatory
|
|
+ `REACT_APP_SSH_SERVER` and `REACT_APP_SSH_PORT` are used to build the .ssh config
|
|
given to users on the home page of CheSSH after authentication

|
|
looking for an opponent
|
|

|
|
for move reminders and other communications
|
