You could use the SecureRandom class to create a random string and attach it to the container to keep the name unique.
I would also suggest adding “run” or something to the name to better visually distinguish it from the deployed containers.

This is looking good. Regarding the labels we talked about on how to identify on-demand instances VS deployed instances.
I think a Label cove.type with on-demand or deployed as the values sound like the right path forward. You could apply this label in the respective instance classes. And then change the code that finds existing containers to also respect that label. Feel free to do this in a separate PR.

Feels more descriptive for what is going on.

Should we remove this and related code since it is not used?

How would you feel naming this OnDemandInstance. Another approach could be to make an Instance module and have Instance::OnDemand and Instance::Deployed or something. That would keep those two very closely related concepts closer together.

Can you add the doc for the return type as well? Thanks.

Needs to be deleted, otherwise it overwrites the delegate for labels above.
