PagerBot

Update your Slack user groups based on your PagerDuty Schedules.

At Songkick, we use PagerDuty for managing our on call schedules. We also have a Slack user group pointing to the people currently on call, so anyone can ping them to alert them of any problems. But updating those user groups every week is both slightly boring, and easy to forget. So when you're working with two services that have APIs, why not automate it?

PagerBot is a simple program to do this. Provided with your PagerDuty and Slack API credentials, and some simple configuration, it will update the usergroups automatically, as well as posting a message to channels you select informing everyone who's currently on the rota.

Installation

Install the dependencies with Glide

glide install

Then build

go build

You should have a nice pagerbot binary ready to go. You can also download prebuild binaries from the releases page.

Configuration

A basic configuration file will look like

api_keys:
  slack: "abcd123"
  pagerduty:
    org: "songkick"
    key: "qwerty567"

groups:
  - name: firefighter
    schedules:
      - PAAAAAA
      - PBBBBBB
    update_message:
      message: ":fire_engine: Your firefighters are %s :fire_engine:"
      channels:
        - general
  - name: fielder
    schedules:
      - PCCCCCC
    update_message:
      message: "Your :baseball: TechOps @Fielder :baseball: this week is %s"
      channels:
        - team-engineering

The configuration should be fairly straightforward, under API keys provide your Slack and Pagerduty keys. Under groups configure the Slack groups you'd like to update. Schedules is a list of PagerDuty schedule IDs, update_message is the message you'd like to post, and the channels you'd like to post them in.

Once done, you can run PagerBot with ./pagerbot --config /path/to/config.yml

It's recommended to run PagerBot under Upstart or some other process manager.

N.B. PagerBot matches PagerDuty users to Slack users by their email addresses, so your users must have the same email address in Slack as in PagerDuty. PagerBot will log warnings for any users it finds in PagerDuty but not in Slack.
