Docker Example - Hubot Slack bot container image built with Ansible

This is an example lightweight Docker image build using Ansible which builds a usable Hubot chat bot that works with Slack. The example is explained in more detail in Chapter 13 of Ansible for DevOps.

Get a Slack API Token for your bot

Follow the instructions in Slack's guide, Slack Developer Kit for Hubot, and get an API token for a bot attached to a new App installed in the workspace of a Slack organization.

Build the Hubot container image

Make sure you have Docker installed on the workstation or VM where this playbook is located, then enter the command:

$ ansible-playbook main.yml

This will generate a Docker image named a4d/hubot-slack, which you should see listed when you run docker images.

Run the Hubot container image

To run the image, run the command below, replacing TOKEN_HERE with the API token your bot uses from Slack:

$ docker run -d --name "hubot-slack" -e HUBOT_

SLACK_TOKEN=TOKEN_HERE a4d/hubot-slack

The container should be running in the background. You can inspect the logs from the bot using docker logs hubot-slack, and you can kill and remove the container with docker rm -f hubot-slack.
