spotminer

What is this?

spotminer automates the Packet.net spot market and a cryptocurrency miner so that you can lower the costs of mining in the cloud and access bare metal performance.

Packet's Spot Market allows users to bid on spare server capacity at reduced rates.

Features:

Set a budget (max price) for each host
Automatically sets the closest stratum server
Places the minimum bid for the host
Uses my mine-with-docker project and cpuminer
Can be run on a timer - i.e. every 5 minutes to ensure reclaimed hosts are replaced
Easy configuration in YAML
Docker Swarm used as an init process to keep the miner running if it crashes
Configure one of the supported algorithms and Stratum of port i.e. hodl or cryptonight
Atom hosts are supported through a separate Docker image

Note: See disclaimer and check T&Cs with any cloud provider before embarking on mining.

Q&A

Watch my video on why you shouldn't mine Bitcoin

If you have additional questions or you want to try mining but don't want to use this example then consult my mine-with-docker project. You can also rebuild your own Docker image/binaries from source.

Installation

Install Go 1.9
Run go install

go install github.com/alexellis/spotminer

This installs spotminer into your $GOPATH/bin directory, so update your $PATH variable if necessary. $GOPATH is normally set to $HOME/go.

The config file is read from config.yml, so copy config.example.yml as a template and fill in your Packet API key and project ID. Set the CONFIG_FILE environment variable for a different filename or path. You must also configure the bitcoin wallet address for your mining here.

packet:
  project_id: ""
  api_key: ""
preferences:
  max_spot_instances: 6
  max_price: 0.15
  mine_algo: "cryptonight"
  port: 3355
  bitcoin_wallet: wallet_address

For mining Hodl use mine_algo: hodl and port: 3352

Packages:

Dependencies are managed through the dep tool.
