alpine-xmrstak

xmr-stak unified miner in an Alpine Linux Docker container.

Using an Alpine Linux container gets you a very lightweight image of ~4MB and the benefits of Alpine Linux's security model.

This image is configured to run the miner as a dedicated restricted user. It is also configured to use environment variables as a corresponding parameter values and it is required to provide 2 pool urls.

Usage

export POOL=...
export WALLET=...
export PASSWORD=...
export WORKERS=... # eg. number of CPU cores
docker run --restart unless-stopped --read-only -m 50M -c 512 yukoff/docker-alpine-xmrstak ${POOL} ${WALLET} ${PASSWORD} ${WORKERS}

Docker Arguments

--restart unless-stopped

In case the miner crashes we want the docker service to restart it.

--read-only

This image does not need rw access. If there are bug/exploits in the pool/software you are a little bit more protected.

-m 50M

Restricts memory usage to 50MB.

-c 512

By default container will use <= half of system cores. Setting a relevant share count will protect you from a runaway process locking your system.

xmr-stak Arguments

--help

All standard xmr-stak arguments are supported, using --help will list all of them.

docker run yukoff/docker-alpine-xmrstak --help

-t

When manually setting threads with -t you need to configure the correct CPU shares for docker.

IE if you have 4 cores, each core is worth 256 (1024 / 4), so for miner to use 3 threads CPU shares for Docker must be set to 756:

docker run -c 756 yukoff/docker-alpine-xmrstak ... -t 3
