Docker: Re-enable multi-arch build: arm, arm64, amd64

[joekhoobyar]

The last multi-arch build was v0.7.0.

Is there any reason not to re-enable it?

[martivo]

This seems to be when it got dropped #79
To work around it:

FROM alpine:3
LABEL maintainer="The Prometheus Authors <prometheus-developers@googlegroups.com>"
RUN apk add smartmontools

RUN wget https://github.com/prometheus-community/smartctl_exporter/releases/download/v0.9.1/smartctl_exporter-0.9.1.linux-arm64.tar.gz && tar xvzf smartctl_exporter-0.9.1.linux-arm64.tar.gz && ls -l smartctl_exporter-0.9.1.linux-arm64.tar.gz && mv smartctl_exporter-0.9.1.linux-arm64/smartctl_exporter /bin/smartctl_exporter && rm -rf smartctl_exporter-0.9.1.linux-*

EXPOSE      9633
USER        nobody
ENTRYPOINT  [ "/bin/smartctl_exporter" ]

@joekhoobyar I suppose this issue is fixed ... recent builds are for all sorts of archs: https://github.com/prometheus-community/smartctl_exporter/releases/tag/v0.10.0

[NiceGuyIT]

Yup. arm64 was built in the latest release.

[jfcoz]

Hi
arm64 is build in release, but the arm64 docker image is still missing on https://quay.io/repository/prometheuscommunity/smartctl-exporter?tab=tags

[NiceGuyIT]

Thanks for catching that @jfcoz. The title and OP doesn't mention Docker. Let's fix that.

[NiceGuyIT]

@SuperQ Can you elaborate on this issue? I couldn't find a related issue in the Prometheus common repo.

From PR #78 (link):

The problem is alpine doesn't tag their multi-arch images the same way Prometheus busybox does.

[SuperQ]

Our standard base container, the busybox container, has a naming convention so we can select which arch output.

For example:

ARG ARCH="amd64"
ARG OS="linux"
FROM quay.io/prometheus/busybox-${OS}-${ARCH}:latest

We use alpine here for the base container so we can get smartmontools installed. I couldn't figure out a way to parameterize the ARCH in the alpine FROM.

In theory, it should work with FROM arm64v8/alpine:3, but I think we would need to run on an ARM worker node for the apk add to function.

[NiceGuyIT]

Adding the response here to keep the thread.

@jfcoz PR #150 didn't work. The prometheuscommunity/smartctl-exporter image shows 2 hashes for linux/amd64.

Meanwhile, prometheuscommunity/smartctl-exporter-linux-arm64 has a linux/amd64 os/arch.

I'm going to revert the changes.

[stepanbaghdasaryan]

Unfortunately there is still no arm64 image in the latest or in v0.11.0 version.

https://quay.io/repository/prometheuscommunity/smartctl-exporter/manifest/sha256:aa34799fcc8d278e427a3995bbdc334e7be6508cb8b2d406f38a3a1a2b1b582f

Is it known when this will be fixed?

[joryirving]

Also interested in an ARM image.

[joryirving]

Thanks to @martivo I successfully built an ARM image:
https://github.com/LilDrunkenSmurf/containers/pkgs/container/smartctl_exporter/167606210?tag=0.11.0
https://github.com/LilDrunkenSmurf/containers/blob/main/apps/smartctl_exporter/Dockerfile

[stepanbaghdasaryan]

@NiceGuyIT Are there some known issues or blockers why you still don't activate the support for ARM64 Docker images??

[dimm0]

Also interested in re-enabling this

[NiceGuyIT]

@stepanbaghdasaryan This issue is to provide a multi-architecture build in prometheuscommunity/smartctl-exporter. PR #150 did not fix the mutli-arch build and thus was reverted.

However, in hind sight, I see it enabled prometheuscommunity/smartctl-exporter-linux-arm64 which is a different image. I.e. it's not multi-arch. Enabling this build until the mutli-arch is fixed is better than having no build. I'll see about enabling PR #150 or creating another PR.

As for why multi-architecture is not working, see SuperQ's comment.

[dimm0]

I'm using gitlab ci/cd, never used GitHub Actions, but it should be pretty straightforward as well with buildx?

https://blog.thesparktree.com/docker-multi-arch-github-actions

[martivo]

If it is any help this is how we build multi arch images using buildx on github actions:

      - name: Set up QEMU
        uses: docker/setup-qemu-action@v3
      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3
      - name: Build and push image
        env:
          DOCKER_USERNAME: ${{ secrets.DOCKER_USERNAME }}
          DOCKER_PASSWORD: ${{ secrets.DOCKER_PASSWORD }}
        run: |
          echo $DOCKER_PASSWORD | docker login -u $DOCKER_USERNAME --password-stdin
          docker buildx build --push --platform linux/arm64/v8,linux/amd64 -t image:latest .

[kashalls]

This can be done with the official docker/build-push-action and docker/setup-buildx-action available with github actions. I can implement this if someone tells me where it should belong or you can look at how I set this up to build a nodejs package into a container with multi-arch: github.com/kashalls/border

[brettinternet]

Is there a workaround with this when using the helm chart prometheus-smartctl-exporter?

[nairol203]

I would really appreciate an arm version for the docker image

[NiceGuyIT]

@SuperQ Can you give me access to the prometheuscommunity organization on CircleCI so I can troubleshoot the build process? Any insight into the build process is also appreciated.

[kashalls]

@NiceGuyIT At one point, I was just going to PR it so that it builds to GHCR packages. If you want I can still do that.

[alex-dna-tech]

My temporary solution is to build a custom container from the released tarball:

docker-compose.yml

services:
  smartctl-exporter:
    build:
      context: ./
      dockerfile: Dockerfile
      args:
        ARCH: "arm64"
        VERSION: "0.12.0"
    restart: unless-stopped
    privileged: true

Dockerfile

FROM alpine AS downloader
ARG ARCH="amd64"
ARG VERSION="0.12.0"

RUN wget -O release.tar.gz https://github.com/prometheus-community/smartctl_exporter/releases
/download/v${VERSION}/smartctl_exporter-${VERSION}.linux-${ARCH}.tar.gz \
    && tar -xzf release.tar.gz__docker-compose.yml__

FROM alpine:latest
ARG ARCH="amd64"
ARG VERSION="0.12.0"

LABEL maintainer="The Prometheus Authors <prometheus-developers@googlegroups.com>"

RUN apk --no-cache add smartmontools
COPY --from=downloader /smartctl_exporter-${VERSION}.linux-${ARCH}/smartctl_exporter /bin/sma
rtctl_exporter

EXPOSE      9633
USER        nobody
ENTRYPOINT  [ "/bin/smartctl_exporter" ]
