hubot-rocketchat

Hubot adapter for Rocket.Chat!

Feel free to join us in the #hubot channel to discuss hubot, and any scripts you might be working on.

Important

BREAKING CHANGES: v2.x.x contains major breaking changes. Starting with this version:

v1.x.x versions of the adapter is only compatible with 0.37.1 and higher of Rocket.Chat Server. Yes, you should be able to continue using v1.x.x adapter and CoffeeScript bots with the most up-to-date version of the server.

If you are using Rocket.Chat 0.35.0 or earlier, please use v0.1.4 of the adapter. (releases between 0.35.0 and 0.37.1 are not recommended for hubot operations)

NOTE

If you want to integrate Rocket.Chat with GitHub or GitLab. Make sure you visit the Rocket.Chat.Ops project before starting. We already have many scripts that add webhook events and access GitHub/GitLab APIs. You can easily extend these scripts for your custom application.

For v2.x.x of the Adapter (Hubot v3 and ES6 support)

If you are writing CoffeeScript bots, need Hubot 2.x and v1.x.x or v0.x.x of the adapter, please see instructions for v1.x.x of the adapter.

The following instructions are ONLY for v2.x.x of the adapter.

Getting your bot connected to Rocket.Chat

Here is a sample run:

picture of a sample interaction with rocketbot

We have a couple of ways for you to get up and started with the Rocket.Chat adapter.

Docker

You can quickly spin up a docker image with:

docker run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
	-e ROCKETCHAT_ROOM='general' \
	-e RESPOND_TO_DM=true \
	-e ROCKETCHAT_USER=bot \
	-e ROCKETCHAT_PASSWORD=bot \
	-e ROCKETCHAT_AUTH=password \
	-e BOT_NAME=bot \
	-e EXTERNAL_SCRIPTS=hubot-pugme,hubot-help \
	rocketchat/hubot-rocketchat
Custom Scripts

If you want to include your own custom scripts you can by doing:

docker run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
	-e ROCKETCHAT_ROOM='general' \
	-e RESPOND_TO_DM=true \
	-e ROCKETCHAT_USER=bot \
	-e ROCKETCHAT_PASSWORD=bot \
	-e ROCKETCHAT_AUTH=password \
	-e BOT_NAME=bot \
	-e EXTERNAL_SCRIPTS=hubot-pugme,hubot-help \
	-v $PWD/scripts:/home/hubot/scripts \
	rocketchat/hubot-rocketchat

Creating a User on the Server

An admin user is required to create the account for the bot to login to.

  1. From Administration > Users menu
  2. Select + to make a new user
  3. Enter Name, Username, Email (tick verified) and Password
  4. Disable Require password change
  5. Select bot from role selection and click Add Role
  6. Disable Join default channels recommended, to avoid accidental listening
  7. Disable Send welcome email
  8. Save

Use these credentials in the bot's environment ROCKETCHAT_USER and ROCKETCHAT_PASSWORD

Note that for bots email, a common workaround to avoid creating multiple accounts is to use gmail +addresses, e.g. youremail+botnam@gmail.com. See this issue for more

Building a Bot

Please see our boilerplate bot [Getting Started docs here][getting-started]!

The boilerplate is essentially just a simple node package that requires Hubot, the Rocket.Chat adapter and Coffeescript for its execution...

"dependencies": {
    "coffeescript": "^2.2.2",
    "hubot": "3",
    "hubot-rocketchat": "^2.0.0"
}

The bot can then be executed using a bin file in production, as seen here. Or via the package scripts locally using npm run local or yarn local

Using the boilerplate example, to start the bot in production, use bin/hubot -a rocketchat - will install dependencies and run the bot with this adapter.

More info in Hubot's own docs here

Configuring Your Bot

In local development, the following can be set in an .env file. In production they would need to be set on server startup.

The Rocket.Chat adapter implements the Rocket.Chat Node.js SDK to load all settings from the environment. So the following are just some of those settings, relevant to Hubot. It has some additional configs, documented here.

Env variableDescription
HubotA subset of relevant Hubot env vars
HUBOT_ADAPTERSet to rocketchat (or pass as launch argument)
HUBOT_NAMEThe programmatic name for listeners
HUBOT_ALIASAn alternate name for the bot to respond to
HUBOT_LOG_LEVELThe minimum level of logs to output (error)
HUBOT_HTTPDIf the bot needs to listen to or make HTTP requests
Rocket.Chat SDKA subset of relevant SDK env vars
ROCKETCHAT_URL*Local Rocketchat address (start before the bot)
ROCKETCHAT_USER*Name in the platform (bot user must be created first)
ROCKETCHAT_PASSWORD*Matching the credentials setup in Rocket.Chat
ROCKETCHAT_ROOMThe default room/s for the bot to listen in to (csv)
LISTEN_ON_ALL_PUBLICDEPRECATED - DO NOT USE
RESPOND_TO_DMIf the bot can respond privately or only in the open
RESPOND_TO_EDITEDIf the bot should reply / re-reply to edited messages
RESPOND_TO_LIVECHATIf the bot should respond in livechat rooms
`INTEGRATION_IDName to ID source of messages in code (e.g Hubot)

* Required settings, unless running locally with testing defaults:

Be aware you must add the bot's user as a member of the new private group(s) before it will respond.

Connecting to Rocket.Chat

We have a couple of ways for you to get up and started with the adapter below.

Docker

You can quickly spin up a docker image with:

docker run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
	-e ROCKETCHAT_ROOM='general' \
	-e RESPOND_TO_DM=true \
	-e ROCKETCHAT_USER=bot \
	-e ROCKETCHAT_PASSWORD=bot \
	-e HUBOT_NAME=bot \
	-e EXTERNAL_SCRIPTS=hubot-help,hubot-diagnostics \
	rocketchat/hubot-rocketchat

Custom Scripts

If you want to include your own custom scripts you can by doing:

docker run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
	-e ROCKETCHAT_ROOM='general' \
	-e RESPOND_TO_DM=true \
	-e ROCKETCHAT_USER=botname \
	-e ROCKETCHAT_PASSWORD=botpass \
	-e HUBOT_NAME=botname \
	-e EXTERNAL_SCRIPTS=hubot-help,hubot-diagnostics \
	-v $PWD/scripts:/home/hubot/scripts \
	rocketchat/hubot-rocketchat

Configuration Options

Here are all of the options you can specify to configure the bot.

On Docker you use: -e VAR=Value

Regular hubot via: export VAR=Value or add to pm2 etc

If ROCKETCHAT_URL is using https://, you MUST setup websocket pass-through on your reverse proxy (NGINX, and so on) with a valid certificate (not self-signed). Directly accessing Rocket.Chat without a reverse proxy via https:// is not possible.

Verify your bot is working

Try:

rocketbot ping

And:

rocketbot help

The example bot under scripts directory responds to:

rocketbot report status

v2.x.x Development

Docker

First clone the source and then move into the directory.

git clone git@github.com:RocketChat/hubot-rocketchat.git
cd hubot-rocketchat

Now we start the docker container.

docker run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
	-e ROCKETCHAT_ROOM='general' \
	-e RESPOND_TO_DM=true \
	-e ROCKETCHAT_USER=bot \
	-e ROCKETCHAT_PASSWORD=bot \
	-e HUBOT_NAME=bot \
	-e EXTERNAL_SCRIPTS=hubot-help,hubot-diagnostic \
	-v $PWD:/home/hubot/node_modules/hubot-rocketchat rocketchat/hubot-rocketchat

Standard

In a Hubot instance once hubot-rocketchat is added by npm or yarn, you can replace the package with a development version directly:

Linked

Setting up a locally linked package is easier for continued development and/or using the same development version of the adapter in multiple bots.

Important notes

For v1.x.x and v0.x.x of the Adatper

Docker-compose

If you want to use docker-compose for this task, add this for v0.1.4 adapter (this must be inserted in your docker-compose.yml):

# hubot, the popular chatbot (add the bot user first and change the password before starting this image)
hubot:
  image: rocketchat/hubot-rocketchat:v0.1.4
  environment:
    - ROCKETCHAT_URL=your-rocket-chat-instance-ip:3000 (e.g. 192.168.2.240:3000)
    - ROCKETCHAT_ROOM=general
    - RESPOND_TO_DM=true
    - ROCKETCHAT_USER=username-of-your-bot
    - ROCKETCHAT_PASSWORD=yourpass
    - BOT_NAME=bot
    - GOOGLE_API_KEY=yourgoogleapikey
# you can add more scripts as you'd like here, they need to be installable by npm
    - EXTERNAL_SCRIPTS=hubot-help,hubot-seen,hubot-links,hubot-diagnostics,hubot-google,hubot-reddit,hubot-bofh,hubot-bookmark,hubot-shipit,hubot-maps
  links:
    - rocketchat:rocketchat
# this is used to expose the hubot port for notifications on the host on port 3001, e.g. for hubot-jenkins-notifier
  ports:
    - 3001:8080

If you wish that your bot listen to all public rooms and all private rooms he is joined to let the env "ROCKETCHAT_ROOM" empty like in the example above and set the env "LISTEN_ON_ALL_PUBLIC" to true.

Please take attention to some external scripts that are in the example above, some of them need your Google-API-Key in the docker compose file.

Alternative Node.js installation with Node Version Manager (nvm) in a local environment on Debian/Ubuntu

# adduser hubot
# su - hubot
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
$ exit
# su - hubot
$ nvm install v4.8.5
$ npm update -g
$ npm install -g yo generator-hubot
$ mkdir hubot
$ cd hubot
$ yo hubot (answer questions and use "rocketchat" as adapter)
$ npm install coffee-script -save

Make sure ~/hubot/bin/hubot is executable: chmod 755 ./bin/hubot

If you need a redis database: apt install redis-server

Set node version: export NODE_VERSION=default

If you want to start your hubot with systemd use nvm-exec:

ExecStart=/home/hubot/.nvm/nvm-exec /home/hubot/hubot/bin/hubot --adapter rocketchat

See EnvironmentFile directive for using environment variables in systemd units

Add adapter to hubot

New install

You can specify the adapter during setup.

First you need to install hubot

npm install -g yo generator-hubot

Then you need to start the setup of the bot

mkdir myhubot
cd myhubot
yo hubot --adapter="rocketchat@1"

It'll ask you a few questions.

Alternatively you can actually answer the questions in one command:

yo hubot --owner="OWNER <owner@example.com>" --name="bot" --description="Bot" --adapter="rocketchat@0.1"

Also be sure to remember the name you specify. This is what the bot will respond to in Rocket.Chat.

You will need to tell the adapter where your install is and what login information to use.

export ROCKETCHAT_ROOM='general'
export RESPOND_TO_DM=true
export ROCKETCHAT_USER=bot
export ROCKETCHAT_PASSWORD=bot
export ROCKETCHAT_AUTH=password

Then start with: bin/hubot -a rocketchat

More Info Here

Existing install

If you already have hubot setup you can add the adapter.

By doing: npm install hubot-rocketchat@2

You will need to tell the adapter where your install is and what login information to use.

export ROCKETCHAT_ROOM='general'
export RESPOND_TO_DM=true
export ROCKETCHAT_USER=rocketbot
export ROCKETCHAT_PASSWORD=bot
export ROCKETCHAT_AUTH=ldap

Then starting your bot specifying the adapter: bin/hubot -a rocketchat

Verify your bot is working

Try:

rocketbot ping

And:

rocketbot help

The example bot under scripts directory responds to:

rocketbot report status

FAQ

Q: I am not trying to stage a denial of service attack, why would I ever want to write a bot?

A: There are many positive and productive use cases for bots. Imagine a customer service support chat. As soon as a customer enters the support channel, a bot immediately identifies the customer and then:

Putting it altogether and then private message the service rep with the information.

Another use-case is a load test bot, imagine a bot that accepts the command:

rocketbot loadtest europe 25, asia 50, usa 100, canada 10

This command specifies a distribution of test bot instances, to be created across globally located data centers.

Once received, the bot:

Q: The architecture of hubot-rocketchat looks interesting, can you tell me more about it?

A: Sure, it is based on hubot-meteorchat. hubot-meteorchat is the hubot integration project for Meteor based chats and real-time messaging systems. Its driver based architecture simplifies creation and customization of adapter for new systems. For example, the hubot-rocketchat integration is just hubot-meteorchat + Rocket.Chat driver.
