Hi, I have a grape plant that I'm growing in a large container. It was given to me and I have no idea of the variety. I just want to keep it healthy and compact. I'd greatly appreciate any tips on pruning and training!

Even if in a large container, you should consider bonsai training it to make the vine grow and look nice long term. So to help with which buds to keep and where, look up bonsai training techniques. So eventually, it may look something like this:
