Hi, I have not used docker before and I was looking through documentation but I could only see stuff related to building a docker image for a particular project. I have several meltano projects and would like to store them on GCP. Would it be a good idea to create a single docker image for all the projects and store them on GCP or create a docker image for each meltano project and store them on GCP? Is there a better way to do that? TIA
