Hi,

For a purpose of performing demo for potential clients a have setup Pega 8.6.0 to run on my MacBook Pro with Apple M1 chip in Docker. The configuration works perfectly fine.

Now I would like to add Cosmos React UI to my local deployment and to achieve this I need to run Constellation UI service.

Thank to this article I managed to elaborate a correct tag (docs still provides wrong tag -- please anyone fix it!) to pull constellation image from Pega's docker registry like this: 

pega-docker.downloads.pega.com/constellationui/service:8.6.0-rc-latest

But now I face another problem: the image seems to be not multi-arch, i.e. it is only built for linux/amd64 architecture.  At least when I run docker manifest inspect command:

docker manifest inspect -v pega-docker.downloads.pega.com/constellationui/service:8.6.0-rc-latest

I am getting the following result:

{
	"Ref": "pega-docker.downloads.pega.com/constellationui/service:8.6.0-rc-latest",
	"Descriptor": {
		"mediaType": "application/vnd.docker.distribution.manifest.v2+json",

		"size": 2620,
		"platform": {
			"architecture": "amd64",
			"os": "linux"
		}
	},
	"SchemaV2Manifest": {

		},
		"layers": [ // omitted for simplicity 
		]
	}
}

When I run similar command for any multi-arch image, for example Nginx:

docker manifest inspect nginx

I am getting manifest list for a number of platforms, including arm64 architecture that M1 is compatible with:

Does anyone know where can I pull constellation UI image for arm64 from? Does anyone have an experience porting amd64 image of constellation UI to arm64?
