shardmaster

Allows you to simply manage (semi automatic) sharding of your discord bot running in a docker swarm (across multiple hosts)

Installation

For the master, you can simply use the docker image (greenbigfrog/shardmaster). For the peers add the following to your shard.yml:

dependencies:
  shardmaster:
    github: greenbigfrog/shardmaster
    branch: master

Usage

View example/README.md for more info

Run the master in a docker container called shardmaster and has mutual network with the peers:

docker service create --name shardmaster --network net greenbigfrog/shardmaster /shardmaster 10

Get shard:

require "shardmaster/peer"
shard = Shardmaster::Peer.get_shard
shard_id = shard[:id]
num_shards = shard[:shard_count]

Post ping every < 5 minutes to keep the shard from expiring:

require "shardmaster/peer"
Shardmaster::Peer.post_ping(shard_id)

Development

docker build -t greenbigfrog/shardmaster-example -f example/Dockerfile .

docker build -t greenbigfrog/shardmaster .
