How do you resolve the problem?
I saw you have the problem too.

NVIDIA/go-nvml#49

[roma-glushko]

@wade-liwei hey Wade 👋 sadly, I had to limit NVIDIA support to linux only in resbeat as nvml doesn't support any other OS (maybe windows, but it was not in the scope of this project).

So I had to add a dummy struct for non-linux platforms:

• https://github.com/roma-glushko/resbeat/blob/main/pkg/resbeat/readers/gpu/nvml_other.go (notice the go:build and +build directives)

..and scope nvml usage to linux only:

• https://github.com/roma-glushko/resbeat/blob/main/pkg/resbeat/readers/gpu/nvml_linux.go (again notice those build directives at the top of the file)

[wade-liwei]

Could you please provide instructions on how to make a Docker image with your project?

[roma-glushko]

@wade-liwei do you want to use it as it was intended e.g. resbeat is installed as an agent into an existing docker image and broadcast utilization of that remaining stuff in the image? In that case, you can simply pull a built binary via curl, for example:

curl -fSL https://github.com/roma-glushko/resbeat/releases/download/1.0.4-dev5/resbeat_Linux_x86_64.tar.gz -o "./resbeat_Linux_x86_64.tar.gz" \
    && tar -vxf resbeat_Linux_x86_64.tar.gz \
    && chmod +x ./resbeat

and then make sure the resbeat is started in the image entrypoint.

You can also built a dedicated resbeat image, but on its own it's not that useful as there is nothing else that would utilize resources that resbeat can measure for you.

[wade-liwei]

got it,
Thank you so much.
But I am not sure the resbeat in alpine work or not.

[roma-glushko]

@wade-liwei yeah, it should work in alpine-based images 👀
I was actually building it in alpine image for dev purposes: https://github.com/roma-glushko/resbeat/blob/main/Dockerfile#L3

[wade-liwei]

Thank you, good man.

[wade-liwei]

hey man

On the 3080 machine, I run the command "make image-build", work ok.
then I run the command "make image" and get the following errors:

[wade-liwei]

I read your build.Dockerfile file, in the file, you just copy go code into the docker image.
In the Dockerfile, build stage,RUN CGO_ENABLED=0 GOOS=linux go build -o /service/resbeat
but failed.

[roma-glushko]

@wade-liwei sorry about delay, Wade 🙏

https://github.com/roma-glushko/resbeat/blob/main/Makefile#L35-L40 - make image may not work with GPU monitoring, you are right. After I introduced that NVML dependency, the binary will be possible to built fully only with NVIDIA tooling in place (which is present in make image-built command since it's using a Dockerfile that is based on a CUDA image
