Minimalistic Docker image with Hubot.
Easy to use if you have a lot of custom scripts and external scripts, but don't want to bake them into image.
HUBOT_NAME- name of the Hubot. Not that necessary, defaults torobot.EXTRA_PACKAGES- comma-separated list of NPM packages, required by your scripts.
Following arguments are getting passed to hubot command by default: --name $HUBOT_NAME --adapter slack. If you want to add something extra - rewrite those arguments in command, during a container creation (Eg.: --name $HUBOT_NAME --adapter slack --alias "\!").
If you want to use custom scripts, it's worth to mount it as a volume (-v <your_path_to_scripts>:/home/hubot/scripts). Also, add scripts dependecies to EXTRA_PACKAGES variable (Eg.: -e EXTRA_PACKAGES=aws-sdk,cron). The entrypoint will install at start-up.
If you want some external scripts to be used and enabled, mount external-scripts.json as a volume (-v <your_path_to_external-scripts.json>:/home/hubot/external-scripts.json).
