Slack Workspace Permissions/Configuration

In order to run this bot, you first need to add the app to your Slack workspace, getting both a Slack App Token and Bot Token. These must be loaded as environmental variables:

export SLACK_APP_TOKEN=xapp-***
export SLACK_BOT_TOKEN=xoxb-***
python3 gpuslackbot.py

Installing as a Systemd Service

Edit the file systemd/system/gpuslackbot.service.d/gpuslackbot.conf to add the required slack token environmental variable (see above). Next test the service, and ensure that it is running:

Copy the relevant files into your systemd configuration directly, e.g.

$ sudo cp systemd/system/gpuslackbot.service /etc/systemd/system/
$ sudo chmod 644 /etc/systemd/system/gpuslackbot.service
$ sudo mkdir /etc/systemd/system/gpuslackbot.service.d
$ sudo cp systemd/system/gpuslackbot.service.d/gpuslackbot.conf /etc/systemd/system/gpuslackbot.service.d/

$ sudo service gpuslackbot start
$ sudo service gpuslackbot status

Multiple Servers/Hosts

This app uses the Slack Socket interface, which does not broadcast consistently across multiple apps listening on one channel. Therefore, when using with multiple servers, you will need to register a seperate app (APP token and Bot token) for each server. Also ensure the app is setup to listen to the correct command.
