Nats oriented images don't support arm64 even though they claim they do #21

Closed kamilgregorczyk closed 1 year ago

kamilgregorczyk commented 3 years ago

Hello, I've been using eats-streaming on arm64 based cluster and recently I moved to Jetstream, I found that:

✅ NATS supports arm64 without any problems

All say that the latest tag has arm64 manifest but it's actually not compatible with arm64, I'm getting exec format error on arm64 machine, while NATS works perfectly on exactly the same server.

kozlovic commented 3 years ago

Not clear on what is not working: NATS Server or (config-reloader, nats-box, etc)? Because this is the repo to produce docker image of the NATS Server.

config-reloader, nats-box, etc don't work even though they have arm64 manifests

kozlovic commented 3 years ago

Not sure where you get that they have manifest that say that they support arm64?

$ docker run --rm -ti mplatform/mquery synadia/nats-box:latest
Image: synadia/nats-box:latest (digest: sha256:caf0c9fe15a9a88d001c74fd9d80f7f6fd57474aa243cd63a9a086eda9e202be)
 * Manifest List: No (Image type: application/vnd.docker.distribution.manifest.v2+json)
 * Supports: linux/amd64

as opposed to NATS server for instance:

$ docker run --rm -ti mplatform/mquery nats:latest
Image: nats:latest (digest: sha256:e976c394120e489ed76b54ef3a4cc2ff9bbe34161aaa623070216204131ce123)
 * Manifest List: Yes (Image type: application/vnd.docker.distribution.manifest.list.v2+json)
 * Supported platforms:
   - linux/amd64
   - linux/arm/v6
   - linux/arm/v7
   - linux/arm64/v8
   - windows/amd64:10.0.17763.1999

natsio is used in the helm chart, not synadia ?

kamilgregorczyk commented 3 years ago

example: https://github.com/nats-io/k8s/blob/master/helm/charts/nats/values.yaml#L255

https://hub.docker.com/r/natsio/nats-boot-config/tags?page=1&ordering=last_updated

kozlovic commented 3 years ago

@wallyqs @variadico Not sure who creates the docker images for the aforementioned tools in the natsio docker repo, but the one hosted on Synadia correctly shows only support for linux/amd64 while the one under natsio shows:

$ docker run --rm -ti mplatform/mquery natsio/nats-box:latest
Image: natsio/nats-box:latest (digest: sha256:51f09970f8fd979bdfc8ff9b38205030384e4592de05cf52c065f9c0ff8bc5de)
 * Manifest List: Yes (Image type: application/vnd.docker.distribution.manifest.list.v2+json)
 * Supported platforms:
   - linux/amd64
   - linux/arm64

Same for boot-config, etc..

wallyqs commented 3 years ago

Thanks we need to look into adding support.

For reloader and boot config are here: https://github.com/nats-io/nack/tree/main/docker

And for the exporter: https://github.com/nats-io/prometheus-nats-exporter/blob/master/docker/linux/amd64/Dockerfile

kamilgregorczyk commented 3 years ago

so from your point of view, which repo is more reliable synadia/ or natsio?

kamilgregorczyk commented 3 years ago

ah yes, the box works, the reloader still crashes (from natsio):

These images have been updated to work on ARM. We tested on ARM 64 Ubuntu.
