A Simple Docker-hosted Hubot

Reading time ~1 minute

I’ve been playing with Hubot a bit lately, and decided to up the ante on the endeavor by creating a Hubot Docker container. There were a couple of misadventures before landing on a stable source container from which it will now be crazy easy to extend and deploy.

I set up Docker using the instructions here.

You may notice from reviewing the Dockerfile that line 6 imports a ‘Universe’ apt source. This is to support dependencies associated with installing a newer version of Node.js (v0.10.19) in a container. To facilitate deployment speed, the container doesn’t include this repository by default. Further down on line 9, another apt repository is added to point to a newer Node.js package. You can find more information about this here.

The Dockerfile includes several different conventions, including RUNning commands, and ADDing files and ENVironment variables to the container.

I had initially tried setting up an S3 Brain with the aws2js Hubot script. I got it working several times, but ultimately found the npm package handling for this and a few other Hubot scripts to be far too brittle to recommend currently. Most often, package retrieval would hang, fail, or occasionally fail silently :/ In each case the following error would appear:

Error: Cannot find module 'aws2js'
