registry image won't run on arm64v8

[milovanderlinden]

I am trying to install registry on a Raspberry Pi 3 B + running the arm64v8 version of hypriot. The registry will not run.

I first tried to run:

Unable to find image 'registry:latest' locally
latest: Pulling from library/registry
docker: no matching manifest for linux/arm64 in the manifest list entries.

Noticed on hub.docker.com that there is a registry for aarch64 and tried:

docker run --platform linux/aarch64 -d -p 5000:5000 --restart always --name registry registry
Unable to find image 'registry:latest' locally
docker: Error response from daemon: invalid platform: invalid platform architecture "aarch64".
See 'docker run --help'.

invalid platform architecture "aarch64".

Looks like the image is reporting the incorrect platform.

@tianon Any ideas here?

Unfortunatly the registry keeps restarting

docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                         PORTS               NAMES
7b4cc8ec0fa5        registry            "/entrypoint.sh /etc…"   36 seconds ago      Restarting (2) 7 seconds ago                       registry

A look at the log shows

docker logs registry
/bin/registry: line 2: syntax error: unexpected word (expecting ")")
/bin/registry: line 2: syntax error: unexpected word (expecting ")")
/bin/registry: line 2: syntax error: unexpected word (expecting ")")

It seems as if the binary in ~/distribution-library-image/registry/registry
is not arm64 compatible.

Hi, here was what I did :
1st: change the base image, which means the image will be bigger than before;

FROM alpine

FROM centos:7

2nd: down load the registry source;
git clone https://github.com/docker/distribution.git

3rd: build registry,and the registry binary file will be created in ./bin/ directory.
make

4th: replace the registry binary file of this project'

5th: rebuild the registry image use this project Dockerfile;
MAYBE TRY!

I just wonder why this repo is not multi-arch supported.

invalid platform architecture "aarch64".

Looks like the image is reporting the incorrect platform.

@tianon Any ideas here?

This specific error looks more to me like a misconfigured daemon or client -- aarch64 shouldn't ever be a platform specifier for Docker images (that'd be arm64 instead).

I think the crux of this issue is really a duplicate of #54 (the registry image doesn't support arm64 right now, and the binary that's included in this repo is a pre-compiled amd64 binary that thus will not and cannot work on arm64 as-is, which is all relevant discussion to have over at #54).

Like workaround, you can use builded image or build from source by self.

Thanks guys, great work. I prefer alpine over centos because of size.
