A simple discord bot that creates and deletes a minecraft server using digital ocean's API.
While hosting a private minecraft server, I realized that me and my friends play on it for - at most - 5 hours per day. And sometimes we would spend several days without logging in. This projects spins up and tears down the server on a digital ocean droplet using a discord bot command.
Server costs without this bot: 24$ per month (fixed)
Server costs with the bot: (0.0004$/hr for snapshot storage) + (~0.036$/hr server cost) = 0.288$(fixed) + 5.4$(avg 5hrs everyday) = 5.688$/month
Note: This calculation is based on Digital Ocean's s-2vcpu-4gb droplet, and doesn't factor in the cost of spinning up a new droplet or creating a new snapshot (which typically costs 0.01$)
This project uses the Digital Ocean API to create and delete droplets. You can also use it to backup and restore the server state. In this project, we use Discord.js to create a discord bot with commands to start, backup and then delete a droplet.
To get started, first copy the .example.env file to .env and provide your env variables
DO_TOKEN=YOUR_DIGITAL_OCEAN_API_TOKEN
SSH_FINGERPRINT=id1,id2,id3..
BOT_TOKEN=DISCORD_BOT_TOKEN
SNAPSHOT_NAME=A_NAME_FOR_THE_SAVED_SNAPSHOT
DROPLET_NAME=A_NAME_FOR_THE_DROPLET
DROPLET_REGION=fra1
DROPLET_SIZE=s-2vcpu-2gb
DROPLET_NAME is the name given to the droplet when it is created or deleted. SNAPSHOT_NAME is the name of the snapshot that will be used to create the droplet. and ssh_keys is a comma-separated list of ssh_keys that can access the droplet. Note that this refers to the dogital ocean fingerprint of the ssh keys, not the keys themselves, the fingerprints should look smoething like this: 3b:16:bf:e4:8b:00:8b:b8:59:8c:a9:d3:f0:19:45:fa
