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:

• CoffeeScript BOTs will no longer be supported, all new bot scripts should be written in NodeJS 8 compatible JavaScript
• Only Hubot v3 will be supported
• you should only use Rocket.Chat Server version 0.63.0 or higher
• Yeoman generator support is discontinued, you should start your project with our hubot v3 boilerplate
• NodeJS 8 or later is required for operations
• The latest ES6 syntax in NodeJS 8, including the popular async-await, is fully supported

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:

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:

er run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=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:

er run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=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 Passwword
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…

endencies": {
"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 variable | Description | | ———————- | —————————————————– | | Hubot | A subset of relevant Hubot env vars | | HUBOT_ADAPTER | Set to rocketchat (or pass as launch argument) | | HUBOT_NAME | The programmatic name for listeners | | HUBOT_ALIAS | An alternate name for the bot to respond to | | HUBOT_LOG_LEVEL | The minimum level of logs to output | | HUBOT_HTTPD | If the bot needs to listen to or make HTTP requests | | Rocket.Chat SDK | A 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_ROOM | The default room/s for the bot to listen in to (csv) | | LISTEN_ON_ALL_PUBLIC | Whether the bot should be listening everywhere | | RESPOND_TO_DM | If the bot can respond privately or only in the open | | RESPOND_TO_EDITED | If the bot should reply / re-reply to edited messages | | RESPOND_TO_LIVECHAT | If the bot should respond in livechat rooms | | INTEGRATION_ID | Name to ID source of messages in code (e.g Hubot) |

* Required settings, unless running locally with testing defaults:

• url: localhost:3000
• username: bot
• password: pass

If you wish that your bot listen to all public rooms and all private rooms it is joined to set the env LISTEN_ON_ALL_PUBLIC to true. ROCKETCHAT_ROOM will be ignored.

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:

er run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=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:

er run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=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:

etbot ping

And:

etbot help

The example bot under scripts directory responds to:

etbot report status

v2.x.x Development

Docker

First clone the source and then move into the directory.

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

Now we start the docker container.

er run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=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:

• cd node_modules from the bot's project root
• rm -rf hubot-rocketchat to delete the published version
• git clone git@github.com:RocketChat/hubot-rocketchat.git to add dev version
• cd hubot-rocketchat move to dev path
• npm install install dependencies

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.

• Change directory to your development adapter path
• npm link or yarn link to set the origin of the link
• Change directory to your bot's project root
• npm link hubot-rocketchat or yarn link hubot-rocketchat to create the link

Important notes

• The first time you run the docker container, the image needs to be pulled from the public docker registry and it will take some time. Subsequent runs are super fast.
• If you are not running Linux (i.e. if you are on a Mac or PC), you cannot use $PWD to mount the volumes. Instead, read this note here (the 2nd note on the page: If you are using Boot2Docker…) to determine the absolute path where you must place the git-cloned directory.

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):

bot, the popular chatbot (add the bot user first and change the password before starting this image)
t:
age: rocketchat/hubot-rocketchat:v0.1.4
vironment:
- ROCKETCHAT_URL=your-rocket-chat-instance-ip:3000 (e.g. 192.168.2.240:3000)
- ROCKETCHAT_ROOM=
- LISTEN_ON_ALL_PUBLIC=true
- ROCKETCHAT_USER=username-of-your-bot
- ROCKETCHAT_PASSWORD=yourpass
- BOT_NAME=bot
- GOOGLE_API_KEY=yourgoogleapikey
u 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
nks:
- rocketchat:rocketchat
is is used to expose the hubot port for notifications on the host on port 3001, e.g. for hubot-jenkins-notifier
rts:
- 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

duser hubot
 - hubot
rl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
it
 - hubot
m install v4.8.5
m update -g
m install -g yo generator-hubot
dir hubot
 hubot
 hubot (answer questions and use "rocketchat" as adapter)
m 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:

Start=/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

install -g yo generator-hubot

Then you need to start the setup of the bot

r myhubot
yhubot
ubot --adapter="rocketchat@1"

It'll ask you a few questions.

Alternatively you can actually answer the questions in one command:

ubot --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.

rt ROCKETCHAT_ROOM=''
rt LISTEN_ON_ALL_PUBLIC=true
rt ROCKETCHAT_USER=bot
rt ROCKETCHAT_PASSWORD=bot
rt 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.

rt ROCKETCHAT_ROOM=''
rt LISTEN_ON_ALL_PUBLIC=true
rt ROCKETCHAT_USER=rocketbot
rt ROCKETCHAT_PASSWORD=bot
rt ROCKETCHAT_AUTH=ldap

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

Verify your bot is working

Try:

etbot ping

And:

etbot help

The example bot under scripts directory responds to:

etbot report status

Developers

We like to make development as easy on ourselves as possible. So passing the love on to you!

Adapter Development

We'd love to have your help improving this adapter. PR's very welcome :smile:

Docker

First clone the source and then move into the directory.

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

Now we start the docker container.

er run -it -e ROCKETCHAT_URL=<your rocketchat instance>:<port> \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=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:/home/hubot/node_modules/hubot-rocketchat rocketchat/hubot-rocketchat

Standard

Installed in hubot you'd hop over into node_modules.

Delete the hubot-rocketchat folder.

Then clone the git repo.

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

Additional details

Look under the scripts directory, you will find a very basic bot there.

Just add your own script in the directory to have it loaded. If you are new to hubot script writing, find out more here.

If you find a bug or compatibility problem, please open an issue.

If you have any enhancements or feature requests, create an issue. If you like what you see, please star the repo.

Finally, if you have created a bot that other users may find useful, please contribute it.

Some important notes

• The first time you run the docker container, the image needs to be pulled from the public docker registry and it will take some time. Subsequent runs are super fast.
• If you are not running Linux (i.e. if you are on a Mac or PC), you cannot use $PWD to mount the volumes. Instead, read this note here (the 2nd note on the page: If you are using Boot2Docker…) to determine the absolute path where you must place the git-cloned directory.

CONTRIBUTORS WANTED

While it is functional, the current adapter is very basic. We need all the help we can get to add capabilities.

Become part of the project, just pick an issue and file a PR.

The adapter code is under the src directory. To test modified adapter code, exit (ctrl-c) the container and run it again.

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:

• fetches recent sales information from the sales dept server
• fetches personal information from the customer data base
• fetches latest notes made by her/his salesperson from the CRM system
• scans the customer's facebook and twitter posts
• obtains details of the last support ticket for this customer

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:

etbot 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:

• parses the distribution
• concurrently ssh to remote Kubernetes controllers and spawns the specified number of test bot instances to start the load test

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.
