hubot-mattermost

Hubot adapter for Mattermost. Enables to add a Hubot bot to Mattermost.

Getting your bot connected to Mattermost

Here is a sample run:

Installation

Follow the "Getting Started With Hubot" guide to get a local installation of Hubot
When you run the command yo hubot it should ask for an adapter, input "mattermost" so it can download this adapter automatically for you
Create an incoming webhook and outgoing webhook integration in your mattermost. You can follow the instructions on Incoming Webhooks and Outgoing Webhooks to setup.
Set the environment variables MATTERMOST_ENDPOINT, MATTERMOST_INCOME_URL and MATTERMOST_TOKEN based on your mattermost configuration.
It's important to remember that if you don't run Hubot alongside with Mattermost (locally) you must ensure that Mattermost instance can connect to the machine where Hubot is installed as it will be running on port 8080. This is due to Webhooks nature (both Incoming and Outgoing) where a HTTP POST will be send both ways for communication purposes (sending and receiving Mattermost/Hubot messages).

Example Installation

npm install -g yo generator-hubot
yo hubot --adapter mattermost

Environment variables

The adapter requires the following environment variables to be defined prior to run a Hubot instance:

MATTERMOST_ENDPOINT string, default: none - URI that you want hubot to listen, need to be the uri you specified when creating your outgoing webhook on mattermost. Example: if you create your outgoing webhook with http://127.0.0.1:8080/hubot/incoming you should set it with /hubot/incoming.
MATTERMOST_INCOME_URL string, default: none - Your incoming webhook url. Example: http://:/hooks/ncwc66caqf8d7c4gnqby1196qo
MATTERMOST_TOKEN string, default: none - Token from your outgoing webhook.

In addition, the following optional variables can be set:

MATTERMOST_CHANNEL string, default: none - Override the channel that you want to reply to.
MATTERMOST_ICON_URL string, default: none - If Enable Overriding of Icon from Webhooks is enabled you can set a url with the icon that you want for your hubot.
MATTERMOST_HUBOT_USERNAME string, default: none - If Enable Overriding of Usernames from Webhooks you can set a custom username to show in mattermost.
MATTERMOST_SELFSIGNED_CERT boolean, default: none - If true it will ignore if MATTERMOST_ENDPOINT has a self signed certificate.

Example for Environment variables

export MATTERMOST_ENDPOINT=/hubot/incoming # listen endpoint
export MATTERMOST_CHANNEL=town-square # optional: if you want to override your channel
export MATTERMOST_INCOME_URL=http://<your mattermost instance>:<port>/hooks/ncwc66caqf8d7c4gnqby1196qo # your mattermost income url
export MATTERMOST_TOKEN=oqwx9d4khjra8cw3zbis1w6fqy # your mattermost token
export MATTERMOST_ICON_URL=https://s3-eu-west-1.amazonaws.com/renanvicente/toy13.png # optional: if you want to override hubot icon
export MATTERMOST_HUBOT_USERNAME="matterbot" # optional: if you want to override hubot name
export MATTERMOST_SELFSIGNED_CERT=true # optional: if you want to ignore self signed certificate

Example with Hubot sending to multiple channels

Although Mattermost doesn't allow multiple channels on a single Incoming/Outgoing hook you can do the following in order to allow Hubot to listen to multiple channels:

Create an Outgoing Hook for each channel to wish to have Hubot. That will give you multiple tokens
Set MATTERMOST_TOKEN global variable with multiple tokens separated by comma

Example:

export MATTERMOST_ENDPOINT=/hubot/incoming # listen endpoint
export MATTERMOST_INCOME_URL=http://localhost:8065/hooks/3eo1wjwyxibnmd5rsusk4h4pgh # your mattermost income url
export MATTERMOST_TOKEN="epboqd78ufyi58nxktgzq9zpho,7ftco7zg5fdkixw7j3okmuo3eo" # your mattermost token for **each Channel**
export MATTERMOST_ICON_URL=https://s3-eu-west-1.amazonaws.com/renanvicente/toy13.png # optional: if you want to override hubot icon
export MATTERMOST_HUBOT_USERNAME="matterbot" # optional: if you want to override hubot name

Note that there is no need to create multiple Incoming Hooks as we can use a single Incoming Hook but specify what channel we want to send the message to as described in the documentation.
