To give you more context of my problem, we are trying to sync image between the cloud registry and our on-prem registry. For the cloud registry, we need to authenticate with a service account which has no password, only the service account key json.

How could we authenticate using image syncer for this case? Should we paste the service account key json to the password field? I tried to do so, but seems it is not possible and not a good way.

Kindly seek your help on that. Thank you!
