Dockerized Ethminer for Nicehash (CUDA)

!dockerized_ethminer_for_nicehash_cuda

This file exists because of how naming gists works in GitHub. This system needs to be improved, a lot.

README.md

Purpose

This is a simple setup to mine ethereum for nicehash within docker on a linux host. The docker container runs the miner using the nvidia-docker runtime to allow for cuda usage, and the script+crontab ensure it stays running. The latter is necessary because sometimes the miner encounters errors but will not exit, so restart: on-failure is insufficient.

Usage

To use, enter your address and worker name in the docker-compose.yaml, put the crontab into your crontab, and the script in the correct location. Ensure the base image for your Dockerfile matches the CUDA version on the host. Last, you want to download and extract the latest release of ethminer and place the ethminer executable and kernels folder in the working directory when building the Dockerfile. This keeps the image size down by not including the deps needed to do so within the container.

cron.sh

#!/bin/bash
util=$(nvidia-smi -q -d UTILIZATION | awk '/Gpu/ { print $3 }')
if [ $util -lt 80 ]; then
  echo "restarting container"
  cd /extra/mining/bin
  /usr/local/bin/docker-compose restart
else
  echo "continuing"
fi
