The lines before are environment variables. We use this to pass important information to the adapter so it knows how to connect to Rocket.Chat. Adding redis or redis brain doesn’t give the bot the ability to remember this.

So a common solution here would be to make use of a bash file. So create a file like start_hubot with contents like this:

#!/bin/bash

export ROCKETCHAT_USER=bot
export ROCKETCHAT_PASSWORD=bot
export ROCKETCHAT_AUTH=password
export HUBOT_YOUTUBE_API_KEY=<your token>

bin/hubot -a rocketchat

Then to make it executable run: chmod +x start_hubot

So then when you want to run hubot you can just do: ./start_hubot
