Get ethereum mining working on Ubuntu + NVIDIA Docker host

gistfile1.txt

Make sure the host has up-to-date nvidia drivers (460 as of this writing)
sudo apt install nvidia-headless-460

Download ethminer to current directory:
wget https://github.com/ethereum-mining/ethminer/releases/download/v0.19.0-alpha.0/ethminer-0.19.0-alpha.0-cuda-9-linux-x86_64.tar.gz

Create Dockerfile as follows:

FROM nvidia/cuda:11.2.0-base-ubuntu18.04
LABEL description="ethminer container for NVIDIA GPU systems"

COPY ethminer-0.19.0-alpha.0-cuda-9-linux-x86_64.tar.gz /ethminer.tar.gz

ENV API_PORT=3333

RUN apt-get update \
    && apt-get install -y --no-install-recommends curl \
    && mkdir -p /ethminer \
    && tar xvfz ethminer.tar.gz -C /ethminer \
    && rm ethminer.tar.gz \
    && apt-get purge --autoremove -y curl \
    && rm -rf /var/lib/apt/lists/* /var/cache/apt/archives/*

EXPOSE $API_PORT

CMD /ethminer/bin/ethminer -U -R \
  -P stratum1+ssl://$ETH_WALLET.$WORKERNAME@us2.ethermine.org:5555 \
  -P stratum1+ssl://$ETH_WALLET.$WORKERNAME@us1.ethermine.org:5555
  
  
Build Docker image:
docker build -t nvethtainer .

Run the container (fill in your own wallet address and worker name)
docker run -d --gpus all --name miner1 -e ETH_WALLET=<your eth wallet address> -e WORKERNAME=<some name> nvethtainer

Monitor mining progress:
docker logs -f --tail 25 miner1
