Build and release for arm7

[mavogel]

I love your projects @caarlos0 . Currently, I'm setting up my raspi, however, I get the error

Failed to pull image "ghcr.io/caarlos0/speedtest-exporter:v1.1.4": rpc error: code = NotFound desc = failed to pull and unpack image "ghcr.io/caarlos0/speedtest-exporter:v1.1.4": no match for platform in manifest: not found

and arch gives me armv7l. AFAICS you are using a general file https://github.com/caarlos0/goreleaserfiles/blob/main/docker.yml, so you might know best how to extend it properly because the effect might then be bigger.

I tried it out locally and got it working by

• adapting the Dockerfile

  FROM alpine
  EXPOSE 9876
  ARG ARCH
  WORKDIR /
  RUN wget -O /tmp/speedtest.tgz "https://install.speedtest.net/app/cli/ookla-speedtest-1.0.0-${ARCH}-linux.tgz" && \
  tar xvfz /tmp/speedtest.tgz -C /usr/local/bin speedtest && \
  rm -rf /tmp/speedtest.tgz
  COPY speedtest-exporter*.apk /tmp
  RUN apk add --allow-untrusted /tmp/speedtest-exporter*.apk
  ENTRYPOINT ["/usr/local/bin/speedtest-exporter"]

• and also passing in a build-arg and making a separate image_templates block as a list of platforms are not supported (see https://github.com/docker/buildx/issues/59) and also in goreleaser the --load is hard-wired (see here) which cannot be combined with --push, which is needed for the lists. So I ended up doing it as follows:

  
  dockers:

• image_templates:
  • 'ghcr.io/caarlos0/{{ .ProjectName }}:{{ .Tag }}-amd64' dockerfile: Dockerfile use: buildx build_flag_templates:
  • "--pull"
  • "--label=org.opencontainers.image.created={{.Date}}"
  • "--label=org.opencontainers.image.name={{.ProjectName}}"
  • "--label=org.opencontainers.image.revision={{.FullCommit}}"
  • "--label=org.opencontainers.image.version={{.Version}}"
  • "--label=org.opencontainers.image.source=https://github.com/caarlos0/{{ .ProjectName }}"
  • "--platform=linux/amd64"
  • "--build-arg=ARCH=x86_64" # <-- here for the speedtest binary download
• image_templates:
  • 'ghcr.io/caarlos0/{{ .ProjectName }}:{{ .Tag }}-arm64' dockerfile: Dockerfile
    use: buildx build_flag_templates:
  • "--pull"
  • "--label=org.opencontainers.image.created={{.Date}}"
  • "--label=org.opencontainers.image.name={{.ProjectName}}"
  • "--label=org.opencontainers.image.revision={{.FullCommit}}"
  • "--label=org.opencontainers.image.version={{.Version}}"

  • "--platform=linux/arm64"
