OpenFaaS PushBullet Connector

Trigger OpenFaaS jobs from Pushbullet

What is Pushbullet?

Pushbullet is a way of connecting your devices together. It has a simple sharing mechanism which allows you to push between desktop, tablet and phone. It allows you to push notes, links and more.

From an OpenFaaS point of view, it's can be used as a managed message queue and allows you to send events from any events with their simple and effective interface.

It's also free and without ads. I've used it for nearly a decade.

Getting started

Getting a Pushbullet token

1. Go to your Pushbullet account homepage
2. Hit the "Create Access Token" button
3. The access token will be displayed once

Create a channel

Pushbullet allows you to create "channels". These can be subscribed to by anyone, but can only be pushed to by the owner. This is perfect for triggering OpenFaaS events.

To create a channel, go to the Pushbullet Create Channel page. This allows you three options - from the point of view of this connector, the only important one is the tag.

• Tag: this MUST be set to the OpenFaaS function's topic name. This is globally-unique.
• Channel name: this is the human-readable channel name. Make it useful.
• Description: the description, obviously.

Topic name

The OpenFaaS Connector SDK sends events to an OpenFaaS function with a topic annotation.

The OpenFaaS Pushbullet Connector treats the Pushbullet tag and the OpenFaaS topic as the same. That means that the event is sent to the OpenFaaS function with a topic annotation that is identical to the Pushbullet tag.

Pushbullet tags are globally-unique.

If the connector can't match the tag to a channel or that the channel doesn't match an OpenFaaS function, the event is simply ignored.
