Local installation of server

Linux/OSX

• git clone {this repo}
  cd {this repo}/course_project/trade-bot

• Assume you have config.yml or config.yaml file in configs folder of type:

  server:
    port: (int) 
    websocket:
      readBufferSize: (int) 1024 by derfault
      writeBufferSize: (int) 1024 by default
      checkOrigin: (true | false) true by default
  
  client:
    # url of server
    url: (string) example - http://localhost:8000
    
  telegram:
    apiToken: (string) your telegram api token from bot father
    webhookUrl: (string) example service for webhooks - ngrok
  
  postgreDatabase:
    host: (string) example - localhost
    port: (string) eample - 8000
    username: (string)
    dbname:  (string)
    sslmode: (string)
  
  redisDatabase:
    host: (string) example - localhost
    port: (string)
    password: (string)
  
  kraken:
    apiurl: (string)
  
  krakenWS:
    requests:

      pingPeriodInSeconds: (int) 10 by default
      maxMessageSize: (int) 512 by default
    kraken:
      wsapiurl: (string)

• Assume you have .env file at the root of project with following:

  DB_PASSWORD = (your postgres db password)
  
  JWT_ACCESS_SIGNING_KEY = (key for signing jwt tokens)
  
  PUBLIC_API_KEY = (public key from kraken futures)
  PRIVATE_API_KEY = (private key from kraken futures)
  

• Run postgres with settings from your config file

  # Example using docker
  
  docker pull postgres
  docker run --name postgres -e POSTGRES_PASSWORD='qwerty' -p 5432:5432 -d postgres

• Run redis with settings from your config file

  # Example using docker
  
  docker pull redis
  docker run --name redis -p 6379:6379 -d redis

• Run migrate files for postgres using migrate

• migrate installation

• curl -s https://packagecloud.io/install/repositories/golang-migrate/migrate/script.deb.sh | sudo bash
  apt-get update
  apt-get install -y migrate  
  

• run migrate

• migrate -path ./migrations -database 'postgres://{postgres_username}:{postgres_password}@{host}:{port}/postgres?sslmode={sslmode}' up

• Then run server

  go run cmd/api/main.go

Installation of server using Docker

Linux/OSX

• You'll need Docker Compose

• Make sure you have all config files like in local installation with some fixes

• Fixes

    postgreDatabase:
      host: db (like db service name in docker-compose file)
    
    ###
    
    redisDatabase:
      host: redis (like redis service name in docker-compose file)

• Run docker-compose

  docker-compose up --build server

• Now simply run migration files like in local installation
