IMAGE_NAME=clr
TAG=v1
IMAGE_URI=$USERNAME/$REPOSITORY/$IMAGE_NAME:$TAG
IMAGE_URI_NEW=registry-1.docker.io/hellosivi/library/$IMAGE_NAME:$TAG

ovhai job run $IMAGE_URI_NEW \

--flavor ai1-1-gpu

We added a private registry in dashboard and it created an url :: registry-1.docker.io/hellosivi/library We tried many combinations of the path. No luck.

Do you support private registries?
