S390x (and other architectures) are not supported for latest version of metrics scraper

[Joseph-Goergen]

The metrics scraper v1.0.8 does not support s390x. v1.0.7 does appear to support it

If you run a skopeo inspect on the image, it says it supports the other architectures

# skopeo --override-arch=s390x inspect docker://docker.io/kubernetesui/metrics-scraper:v1.0.8 --raw
{
   "schemaVersion": 2,
   "mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",
   "manifests": [
      {

         "platform": {
            "architecture": "amd64",
            "os": "linux"
         }
      },
...
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "size": 736,

         "platform": {
            "architecture": "s390x",
            "os": "linux"
         }
      }
   ]
}%

But docker inspect says otherwise

We are asking for a new patch release that re-supports the other architectures.

I think the docker build command is missing a --platform, so the image gets the wrong info... The actual contents seem OK though, being cross-compiled using the GOARCH cross-compilation.

[afbjorklund]

Main difference between the images seem to be the use of BuildKit ? (Says docker history anyway)

[tumberino]

@afbjorklund Is it possible to get a new release of the docker images to have the correct architecture labels? Since #56 has been merged.

[tumberino]

@maciaszczykm Is there a plan for a new release or can the get new images published with the architecture fix in?

[maciaszczykm]

New images are there, but it will take few more weeks to release them with chart etc.

[rtheis]

@maciaszczykm where do we find the images? https://hub.docker.com/r/kubernetesui/metrics-scraper/tags show v1.0.8 as the latest release.

[maciaszczykm]

New scraper image was just released.
