In theory it should be possible, as many of cloud service providers have the option of importing an OVF template into the cloud. Example is google: Importing virtual appliances | Compute Engine Documentation
However from the networking point of view - I have no clue how this type of appliance will perform the actual scans, thats why I am a bit unsure how the VA will be configured. But probably you know this part better.
Why do you want a container? What exactly would you do with it?
We want to use it the same way as standard appliance. But we were asked by our infrastructure team if we can deploy Discovery as a container instead of a virtual appliance. So I'm just trying to find out if it's possible or not. The reason why we were asked to do so is because of our internal policy.
