Cadvisor for ARM

[mboussaa]

I guess the current version of Cadvisor doest not support RPI docker images. I am not sure about that since I did not test it yet.
Is it possible to provide support for ARM images?

I wonder if cross compilation for arm just works.. cc @luxas

I would just add GOARCH=arm to go build command in build/build.sh.
It should just work.

However, if we want to cross-build a docker image, we probably have to base it on debian for other arches than amd64. See the hyperkube image how to do this: https://github.com/kubernetes/kubernetes/blob/master/cluster/images/hyperkube/Makefile

If we decide on a naming convention for non-amd64 cAdvisor and think we should do it, I may send a PR that builds cAdvisor images for arm, arm64, ppc64le.

It might help to automate the docker image release process in cadvisor to
ensure that arm images are built for every release.

So for instance cAdvisor image does not handle ARM image?

[luxas]

@mboussaa I'm not really sure what you mean.
On an ARM host, cAdvisor built for ARM may monitor ARM containers without problems.

The current cadvisor image on docker hub is built for linux/amd64 (like the most other things), so it won't run on an ARM host at all

I tried to cross compile with Docker 4 Mac and a golang:1.6.3 container.

1. docker run -it --rm golang:1.6.3
2. apt-get update && apt-get install vim
3. go get -d github.com/google/cadvisor
4. cd $GOPATH/src/github.com/google/cadvisor
5. vim build/build.sh and add env GOARCH=arm GOBIN=$PWD go "$GO_CMD" ${GO_FLAGS} -ldflags "${ldflags}" "${repo_path}"
6. make build

I get the following error:

vendor/github.com/opencontainers/runc/libcontainer/cgroups/systemd/apply_systemd.go:17:2: no buildable Go source files in /go/src/github.com/google/cadvisor/vendor/github.com/coreos/go-systemd/util
Makefile:35: recipe for target 'build' failed

Do you know what I'm doing wrong ?

I compiled cadvisor and managed to edit the dockerfile to work on my raspberry pi.
I uploaded the result here.
I decided to compile it my self because any other versions weren't up to date :D

[rjlee]

@Brain-Gamer could you provide the dockerfile/instructions so others can do the same ?

[fgardt]

@rjlee sure! It takes maybe a few days but I will do it ;)

[fgardt]

@rjlee I forked this repo and added the information you asked for in the readme. If you need anything else just ask ;)

[rjlee]

@Brain-Gamer many thanks for sharing.
