Hi @C Riley
Thanks for reaching Microsoft Q&A
This issue is related to the lack of an image manifest, as you can check with the command:
docker manifest inspect docker.io/presearch/node
Azure ACI requires images to have a manifest and so that image although public, currently will not run in Azure ACI,
Please note that Microsoft is aware of this and the product group is looking into this matter,
As a workaround you can push that same image to an Azure ACR or other repository, that will add the required manifest and you will be able to run the container with the image.
Hope this helps. Please "Accept as Answer" if it helped, so that it can help others in the community looking for help on similar topics.
