Somebody has done quite a good job : https://github.com/Anthony-Tatowicz/docker-ethminer
But, if you’re using Nvidia’s Pascal cards, you’re better off using CUDA 8.0 not 7.5 as of the above’s Dockerfile says.
So the new Dockerfile should be begin with:
But, if you rush to building it now, if you like me, you will find some errors during
cmake, here is one of them :
Building NVCC (Device) object libethash-cuda/CMakeFiles/ethash-cuda.dir/ethash-cuda_generated_ethash_cuda_miner_kernel.cu.o
Fortunately, there are others facing the very same problem as well, here is the thread: https://forum.ethereum.org/discussion/2227/cuda-miner/p34
And here is the response from the author of CUDA cpp-ethereum, namely Genoil:
@Cubirez yes ran into that myself too. This was caused by somebody who tried to make copatibility with Fedora work. I’ll fix it in the rep later, but for now, add –std=c++11 to the NVCC flags in CMakelists.txt in libethash-cuda folder
So, actually, you have to make some change to the cloned source.
Here, I will change the course of the Dockerfile a bit, so that we can do the change :
git clone https://github.com/Genoil/cpp-ethereum.git cd cpp-ethereum/libethash-cuda vim CMakeLists.txt
To, by adding
Now, to the Dockerfile, instead of cloning we will be copying instead:
COPY cpp-ethereum /cpp-ethereum RUN cd cpp-ethereum \ && mkdir build \ && cd build \ && cmake -DBUNDLE=cudaminer -DCOMPUTE=61 .. \ && make -j8 \ && mkdir /data
Note : I added
-DCOMPUTE=61 flag because I use GTX 1060, this should be optional, but it feels better being explicit.
It should work now!
nvidia-docker run -it --rm <yourimage> /cpp-ethereum/build/ethminer/ethminer -U --benchmark
Note : use
-G = opencl,
-U = cuda
I got something like
